| − | ===Preface===
| |
| − | The purpose of this wiki page is to go in depth of how the different alloys are produced by Paiste’s supplier(s), past and present.
| |
| − | Paiste is a unique cymbal company in that their alloys are substantially different in quality and sound characteristics compared to the “Turkish way” of B20 alloy production. Specifically, this difference in sound quality and consistency is a result of the way the alloys are manufactured.
| |
| − | This page will also cover briefly other major cymbal companies and how their alloy is manufactured.<br>
| |
| − |
| |
| − | ==Paiste’s development and use of B20 alloy==
| |
| − | Paiste does not have a foundry, they have traditionally used an outside supplier to provide all of their alloys with the first production stage completed: blanks are produced at the specified size and thickness and delivered to Paiste.<br>
| |
| − |
| |
| − | *The B20 “blanks” were supplied by [https://de.wikipedia.org/wiki/Swissmetal '''Swissmetal'''] from 1957 to 1994, they were originally called "Metallwerke Dornach AG".<br>
| |
| − |
| |
| − | *Metallwerke Dornach supplied B20 alloy for the Swiss mint, Swiss coins were made out of B20 bronze.<br>
| |
| − |
| |
| − | *Robert Paiste founded the Swiss factory across the lake from where Metallwerke Dornach was located by accident (Paiste had not used B20 alloy up to that point), little did he know they were the only foundry and mill that produced B20 bronze in all of Switzerland and possibly all of western Europe!<br>
| |
| − |
| |
| − | *Robert Paiste initially worked with Swissmetal and developed a process of rolling B20 thin enough for B20 cymbal production: [https://youtu.be/KH2TPkhL0Ik?si=fTiEIgBqsqbBE5d9 <b>Fritz Steger's explanation of the sourcing and development of Paiste's B20 alloy</b>].<br>
| |
| − |
| |
| − | *The Formula 602 and Sound creation lines were discontinued around 1994 because Swissmetal stopped making B20 blanks. It is understood that Swissmetal went through substantial financial difficulties during this time, it’s also assumed it wasn’t cost effective anymore as Paiste would have been a small volume customer. In addition, Paiste was promoting the "Signature" or B15 cymbals that were designed to replace both series, so Robert Paiste did not pursue a replacement supplier.
| |
| − |
| |
| − | *"Weilandworks" in Vöhringen Germany now supply all of Paiste's alloys but specifically: they supply the B20 blanks for the “classic 602’s” and "Modern essentials 602’s". when first presented to Robert Paiste, he asked for some small changes (changes in processing temperature in order to reproduce the classic 602 sound)<br>
| |
| − |
| |
| − | *B20 and B15 are "two-phase" alloys: meaning some of the tin is not dissolved in the copper grains but exists between them, in its natural state it is very brittle, there is a large amount of work done to the material (reheating/recrystallisation) to get the material conditioned so it can be rolled to the correct thickness without it cracking.<br><br>

| |
| − | [[File:Slide 2.jpg|thumb|right|350px|hot vs. cold rolling showing change in crystalline structure]]
| |
| − | *It believed that Paiste's material suppliers (Weiland works and Swissmetal) have used this production process for a long time, possibly as far back as 1957 when Swissmetal first starting supplying B20 blanks to the Swiss factory.
| |
| − | *Wielandworks has their continuous casting system in their plant in England. <br>
| |
| − |
| |
| − | ===Continuous strip or band casting process===
| |
| − |
| |
| − | Weilandworks uses the continuous strip or band casting process for producing B8, B15 (and most likely) B20 blanks it supplies to Paiste.<br>
| |
| − |
| |
| − | '''What is the difference between gravity/ingot casting and continuous casting?'''<br>
| |
| − |
| |
| − | In "ingot casting", individual molds are filled with molten bronze to produce "ingots" whereas in continuous casting, the molten alloy is solidified into a very long "semi finished" billet, and at the same time, cut into slabs or planks for subsequent hot or cold rolling in the finishing mills.<br>
| |
| − |
| |
| − | '''What is the advantage of continuous casting?'''<br>
| |
| − |
| |
| − | Continuous casting helps improve the quality of metal products by reducing impurities and variations in size and shape, this results in consistent and higher-quality products with fewer defects.<br>
| |
| − | The continuous casting method offers a superior surface finish and virtually eliminates internal porosity and centerline shrinkage during cooling compared to ingot casting.<br>
| |
| − | The majority of bronze castings are produced through the individual ingot casting process. However, there are clear deficiencies in the this choice when compared to continuous casting.<br>
| |
| − |
| |
| − | '''What are the disadvantages of continuous casting?'''
| |
| − |
| |
| − | It isn't economical to use this method with special metal alloys in low volume and small quantities<br>
| |
| − |
| |
| − | In conclusion, continuous casting offers several advantages, including high productivity, consistent quality, and cost-effectiveness.<br>
| |
| − |
| |
| − | ===Second hot rolling stage:===
| |
| − | At the mill, the desired thickness is created by hot rolling [1] (see bottom of page for notes) B20 and B15 in multiple passes from a thick plank into a long thin sheet slightly thicker than the thickness required by the heaviest cymbal.
| |
| − | The hot rolling process forms the desired crystalline structure that contributes to the sound of cymbal and makes the material durable but pliable enough that it can be worked and hammered without cracking.<br>
| |
| − | After being rolled out to approximate size and thickness, round blanks are cut to the specified size and delivered to Paiste.<br>
| |
| − |
| |
| − | *All of Paiste's cymbal blanks use this process with the exception of the Masters, Twenty and Twenty Custom Collection series.<br>
| |
| − |
| |
| − | *Both B20 and B15 alloys are cut into slabs before hot rolling (B20) and cold rolling (B15) to reduce the thickness to the proper level.
| |
| − |
| |
| − | *Wielandworks rolls the B15 alloy at their Birmingham England facility.
| |
| − |
| |
| − | *B15 slabs have to be reheated (annealed[3]) after several cold rolling passes, they then have the surface cracks ground off before final finishing.
| |
| − |
| |
| − | *In a 2006 interview, Robert Paiste stated that his big regret in 1994 was when their original B20 supplier Swissmetal stopped production, Robert did not buy and remove the 2nd hot rolling stage and move it to a new facility where Paiste could finish rolling the B20 slabs themselves.<br>

| − | ==Stage 2. Paiste's production process at their factory==
| |
| − | '''Hammering:''' <br>
| |
| − | Paiste is the only company out of the major cymbals companies that uses the "manual machine hammering" technique to shape the curve or “bow” of all of their top line cymbals, they invented and have used the same process since 1952 (they got their first hammering machine in 1952).<br>
| |
| − | Up until 1986 all Paiste cymbals were manual machine hammering with the exception of the 101 series.<br>
| |
| − | An electro pneumatic hammer is operated manually by the cymbal-smith, he wears a mount with a spindle on his left knee that holds the cymbal, he uses his thigh to move the cymbal in and out from the hammer to position the blows, with his right foot he controls the power/depth of the hammer blows, with his hands he rotates the cymbal to evenly distribute the hammer marks.<br>
| |
| − | Paiste has been using this technique and the same type of machines since at least the mid 50’s or earlier.<br>
| |
| − | The next step is fine tuning: a different cymbal-smith now hammers the cymbal by hand to fine tune the shape and checks the bow with a ruler and on a steel flat table to make sure the edges are straight, he also checks the cymbal against a “master” for hammer pattern and shape of the bow.<br>
| |
| − |
| |
| − | '''Specification card:'''<br>
| |
| − | Each cymbal-smith has a “specification card” that travels with each model/size of cymbal, it tells him the exact weight, thickness and hammering pattern for that cymbal.<br>
| |
| − |
| |
| − | '''Lathing:''' <br>
| |
| − | All Paiste's top line cymbals are lathed by hand, up until 1986 all Paiste cymbals were lathed by hand with the exception pf the 101<br>
| |
| − | Lathing does two things: brings the cymbal down to the desired thickness and creates the lathing grooves which refines the sound and defines the character of that cymbal line.<br>
| |
| − | The cymbal-smith checks the thickness of the cymbal with a micrometer during this process, the thickness must be no more or less than 0.01mm.<br>
| |
| − |
| |
| − | '''Finishing:''' <br>
| |
| − | The edges are cleaned up and chamfered, a serial number is laser etched into the bottom. The cymbals then have their respective logo, model, size printed on them and a protective coating is applied (Paiste was the 1st. to do this with the 602 series in the 1960’s).<br>
| |
| − |
| |
| − | '''Quality control:''' <br>
| |
| − | Each cymbal is tested against a finished “Klangmuster” ("sound sample") for consistency, if it does not pass the cymbal is rejected and scraped.<br>
| |
| − |
| |
| − | == The German factory ==
| |
| − | [[File:German 602.jpg|thumb|right|350px|Early 602 finished at the German factory]]
| |
| − | The German factory was the 1st, to restart production after WWII around 1947/48, in 1957 Robert Paiste moved to Nottwil Switzerland by himself and setup the Swiss factory.<br>
| |
| − | The German factory is the sole producer of gongs, and has been since opening.<br>
| |
| − | Historically, both factories made both levels of product except the German factory didn't make any B20 cymbals or Giant beats.<br>
| |
| − | Many 2002's were made at the German factory in 70s and 80s, there is a notion among some drummers that the Swiss versions are better quality... they are not, some German versions are usually a little heavier and a little darker sounding. <br>
| |
| − | The German factory also "finished" a small number of 602s during the preserial days, there are also examples of German 602's from the mid 1970's as well.<br>
| |
| − | The German factory made practically all the vintage Paiste lines: 2002 (up to 1986), Sound formula, 2000, 1000, 400, 200, Stambul '65, Stambul, 404, 505, Ludwig cymbals, Dixies, Supers, Stanoples, Zilkos, etc.<br>
| |
| − | They still make all the lower lines and "OEM" cymbals.<br>
| |
| − | American drummers are less familiar with German Paistes because the Swiss factory did most of the exporting, the German Paistes were meant for the German market and probably certain countries in central and eastern Europe.<br>
| |
| − | It is believed that only the German factory has the spin forming machines so all the current lower lines are "started" there and finished in Nottwil for export.

| − | Past: Visions, Sound formula.<br>
| |
| − |
| |
| − | Paiste's B15 (Signature Sound Alloy) were initially supplied by "Kovohutí Příbram" foundry/mill in the Czech republic, they had serious issues with cracking of the finished cymbals, Weilandworks resolved the issue and production was moved there pernamently: [https://youtu.be/senTufOv2n4?si=cA11bOQev74yQqoq Fritz Steger describes the early production issues with B15]<br>
| |
| − | B15 like B20, goes through some of the same processes: initially hot rolled to about 60mm thickness then the last stages is cold rolled. <br>
| |
| − | Cold rolling alloy allows for greater consistency between blanks compared to traditional B20 cymbal alloy, and is more inline with Paiste's B8 production methods.<br>
| |
| − | When they reach the Paiste factory, B15 blanks are reheated to "anneal" them (soften) and then quenched in water, a bell is stamped in the blank, it is now ready for hammering.<br>
| |
| − | After this process, the blank is allowed to cool for 24 hours. As a result of annealing, the material is now more pliable, tougher and ready for hammering.<br>
| |
| − | Once we reach this stage the production process (hammering/lathing) is virtually identical to all the other top line series regardless of alloy.

| |
| − | '''Paiste's description of the production process in the U.S. patent'''<br>
| |
| − | "<i>An alloy containing, for example, 14.7 percent by weight tin, 0.08 percent by weight phosphorus and 85.22 percent by weight copper is initially melted in an induction melting furnace.<br>
| |
| − | The melt is delivered at a temperature of 1000° C. to 1200° C. into a heat retention or holding furnace of '''a strip or band casting installation. A strip or band is cast'''.<br>
| |
| − | The cast strip or band has, for example, a width of 670 mm and a thickness of 18 mm. This strip or band cannot be coiled and is therefore cut into plates of approximately 3 to 4 meters length.<br>
| |
| − | Such plates are now homogenized at 600° C. to 700° C. during about 10 to 25 hours.<br>
| |
| − | Then the casting and oxidation skin is removed by means of a milling tool or cutter or equivalent structure.<br>
| |
| − | Thereafter the plates are initially only slightly cold rolled, i.e. by about 20 percent and then recrystallized at temperatures between 500° C. and 700° C.<br>
| |
| − | This process cycle of cold rolling and recrystallization takes place until a final sheet or plate thickness of 1 to 2 mm is obtained.<br>
| |
| − | Then a final annealing is carried out at temperatures between 400° C. and 500° C.<br>
| |
| − | The obtained grain size then should be between 0.003 and 0.015 mm. The hardness should lie between 150 250 kilopounds per square millimeter, depending on the strived for sound or tone character.<br>
| |
| − | Now circular blanks or discs of, for example, 200 to 610 mm in diameter are cut out of this sheet or plate from which there is formed the aforedescribed cymbal."<br>

| |
| − |
| |
| − | B8 alloy is very different compared to B20 and B15: it's softer, much more malleable, easier to work and doesn't require multiple heating cycles before each rolling stage in order to prepare it for hammering.<br>
| |
| − | Paiste's B8 alloy blanks originally came from Metallwerke Dornach AG, aka: Swissmetal, the same source as their B20, they are now supplied by the "Wieland works".<br>
| |
| − | (Cold rolling operation actually increases the strength via "strain hardening" up to 20%, it also improves the surface finish and holds tighter tolerances).<br>
| |
| − | Once they arrive at Paiste, they would heat the center of the cymbal in order to press the in the bell. <br>
| |
| − | For the china type cymbals they "spinform" the shape of the bell into the unique cylindrical shape.<br>

| |
| − | [[File:Spin forming.jpg|thumb|right|350px|Spin forming]]
| |
| − | Staring in 1978 with the 101 series, Paiste started using the "spin forming" process to shape their cymbals instead of hammering. In 1986 it is believed that several of the new lower lines (200, 400 and 1000) used this process and the majority of the lower lines since 1986 use the spin forming process.<br>
| |
| − | It is believed that only the German factory has the spin forming machines, so all the lower lines would start there before being finished at the Swiss factory.<br>
| |
| − | Current lines most likely using this process: 900, 900 colorsound, Pst 8, Pst 7, Pst 5, Pst3, 101 brass, Pst X.<br>
| |
| − |
| |
| − | '''What is the spin forming process?'''<br>
| |
| − |
| |
| − | Metal spinning, also known as spin forming most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. Spinning can be performed by hand or by a CNC lathe.<br>
| |
| − | A pre-sized metal disk is then clamped against the block by a pressure pad, which is attached to the tail stock. The block and workpiece are then rotated together at high speeds. A localized force is then applied to the workpiece to cause it to flow over the block. The force is usually applied via various levered tools.
| |
| − | The metal is formed into seamless asymmetric shapes by a combination of rotational motion and force. In this process a tube or a disc of metal is rotated at a high speed, and is then transformed into the desired axially symmetrical object. This process of metal spinning has similar techniques to clay pottery sculpting and can be performed using CNC, hydraulic power or by hand. <br>

| − | ===Twenty and Twenty Masters Collection production===
| |
| − | The original “Twenty” blanks were supplied from the Foundry of Murat Diril in Turkey along with pre-work done to the cymbals before they were shipped off to Switzerland for completion.<br>
| |
| − | There were well publicized issues with the quality of the blanks and high rejection rate, so Turkish suppliers were changed before the current Twenty Custom/Twenty Masters series started.<br>
| |
| − | The process with their new supplier according to Paiste: "They begin by being hammered and shaped in Turkey, then we send them to Switzerland where we do the finish hammering and lathing and all the other work that makes it a Paiste cymbal." <br>
| |
| − | All the hammering is done by hand according to Erik Paiste: “Paiste emphasizes that every crucial stage of the production is completed by hand, from the initial casting to the lathing and hammering.”<br>

Michael is widely respected as one of the finest cymbal makers there is. He has definitely inherited all of his father's experience and knowledge.

| − | ==Why is UFIP important and why are they different?==
| |
| − | [[File:Centrifugal-casting-process.jpg|thumb|right|350px|centrifugal casting]]
| |
| − | UFIP is the second oldest cymbal company (est. 1931) to produce cymbals from B20.<br>
| |
| − | UFIP is unique because they come from the Italian culture of church bell making or “bronze casters” as they call themselves, their cymbals are not hot or cold rolled in anyway.<br>
| |
| − | UFIP uses the traditional techniques that have been used for several hundred if not a thousand years on casting bronze church bells.
| |
| − | Originally their cymbals were gravity cast, at some point we believe possibly in the mid-1970s UFIP developed the “rotocasting” technique where molten B20 bronze is poured into a spinning mold that is made in the shape of a cymbal, this includes the bell and the “bow” or curve of the cymbal. This process produces a dense and consistent alloy without inclusions, porosity or defects. This process also creates a different sounding cymbal because it is not hot rolled or cold rolled at any point.<br>

| |
| − | ===What is centrifugal casting and why is it better?===
| |
| − |
| |
| − | The process involves using a centrifugal force (high-speed rotation action) to exert pressure on the molten metal, and it is poured from an external source into a spinning die. The centrifugal force acts to distribute the molten metal in the spinning die at pressures close to 100 times the force of gravity. The mold rotates until the whole casting solidifies. Because of the high G-forces involved in this casting method, the less dense materials, including impurities, are forced to go to the inside diameter periphery of the part, which is subsequently removed by machining, and defects related to gas and porosity are reduced.<br>

| − | == A word about "cast" vs. "sheet bronze" cymbals ==
| |
| − | Zildjian and Sabian (mainly Zildjian) have for many years used these terms in their marketing and advertising, they've alluded to in the past about B8 (and possibly B20 602's as well) "sheet bronze", "cookie cutter" cymbals being "stamped and formed" and inferior in both sound and quality (see advertisements below).<br>
| |
| − | There are many misconceptions created by these statements: both alloys are "cast" at some point, B20 is delivered to Zildjian and Sabian as cast ingots from their in house foundry, they then heat and "hot roll/cross roll"<br> (see link below) the ingots to the general size and thickness, they must be reheated after every rolling stage (Paiste's B20 supplier uses this same process), they are also tempered/annealed and quenched (see link below) during this time and before being stamped into shape (for most of thier lines) and lathing.<br>
| |
| − | The reason for this is the B20 alloy is very brittle (the tin doesn't completely mix with the copper at a microscopic level, in the B8 alloy it does), there is a large amount of work done (heating, reheating quenching) to the material just to get it conditioned so it can be hammered and lathed without cracking!<br>
| |
| − | The B8 alloy is very different, it's much more malleable and workable, the foundry (Weilandworks) most likely pours out long square ingot bars (the casting part), it is then cooled and "cold rolled" multiple times (see link below) into long thin sheets (hence Zildjian's term "sheet bronze"), they then cut circular discs out of the sheet and deliver them to Paiste. Cold rolling operation actually increases the strength via "strain hardening" up to 20%, it also improves the surface finish and holds tighter tolerances.<br>
| |
| − |
| |
| − | To summarize:
| |
| − | B8 production techniques and the alloy itself does not make it inferior for cymbal making, it's just different, it's inherently easier to work with, its' more consistent batch to batch and doesn't suffer the higher rejection/defect rate that B20 does, this means B8 cymbals are less expensive to produce, not inferior quality. Paiste figured this out in the early/mid 60's and has mastered the production techniques and sound qualities of this alloy.<br>
| |
| − | It's also telling that neither Zildjian or Sabian have attempted to produce a top level B8 cymbal (Meinl has for decades), could it be that Zildjian and Sabian can't or don't want to compete with Paiste and Meinl head to head with this alloy?<br>
| |
| − | '''We recently received first hand accounts that both Sabian and Zildjian use "Weiland works" as their supplier for B8 blanks, the same foundry that Paiste uses!'''<br>

| |
| − | === Rolling ===
| |
| − | <i>'''[1]''' Rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.<br>
| |
| − | The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled:<br>
| |
| − | *If the temperature of the metal is above its recrystallization temperature, then the process is known as '''hot rolling.'''<br>
| |
| − | *If the temperature of the metal is below its recrystallization temperature, the process is known as '''cold rolling.'''<br>
| |
| − |
| |
| − | ===Cross rolling===
| |
| − | '''[2]''' Cross rolling is a way of reducing the directional dependency of different properties of the rolled plate.<br>
| |
| − | Cross rolling is normally done by changing the rolling direction by 90° about the normal direction.<br>
| |
| − | Changes in residual stress distribution cross rolling leads to rolled product of comparatively uniform mechanical properties in all directions.<br>
| |
| − |
| |
| − | ===Annealing===
| |
| − | '''[3]''' Annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness and makes it more workable.<br>
| |
| − | It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooled.<br>
| |
| − | Bronze can be either cooled slowly in air, or quickly by quenching in water. In this fashion, the metal is softened and prepared for further work such as hammering, shaping, stamping, or forming.<br>
| |
| − |
| |
| − | ===Tempering===
| |
| − | '''[4]''' Tempering is a process of heat treating, it is done to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.<br>
| |
| − | The exact temperature determines the amount of hardness removed, and depends on both the specific composition of the alloy and on the desired properties in the finished product.</i><br><br>
