FOUNDRY TECHNOLOGY
The Zollern factories The ZOLLERN GmbH & Co. KG is a company with worldwide operations, employing over 3000 employees in the business fields of transmission technology (automation, gears and winches), plain bearing technology, engineering elements, foundry technology and steel profiles. Copper-aluminium alloys 4 Copper-tin and copper-tin-zinc casting alloys 6 Copper-zinc casting alloys 8 Copper-lead-tin casting alloys 8 Copper-nickel casting alloys 10 Copper casting alloys 10
FOUNDRY TECHNOLOGY 2 3 Casting on highest level Since the company foundation in 1708 components of metallic materials are cast. Besides an iron and steel a bronze foundry was erected around 1890. Nowadays mainly sand castings of copper and copper alloys are produced but also castings of high and low alloyed steels and nickel alloys. For the hand- or automatically formed parts resinoid-bonded sands are used. This ensures an excellent surface as well as very close tolerances. Components with special requirements can be cast as per the shell moulding process using ceramic moulds and ceramic cores. Castings of copper alloys can be realized up to unit weights of abt. 7,000 kgs and up to abt. 1,200 kgs of steel. A well equipped machine shop with latest CNC lathes allows pre- or finish-machining of castings as per customers drawings. In the laboratory and testing department all destructive and non-destruc - tive tests and examinations are possible. Our production is certified to DIN EN ISO 9001 : 2000. Quality and service are our basis for successful work on the national and international market.

Components for the electrical, welding and mechanical engineering sector, e.g. electrode holders, also with cast-in cooling pipes, welding jaws, copperized bars, contacts and clamping jaws in resistance welding applications, cooling elements for chemical and metallurgical processes. 1 For ISO, F and GB the abbreviations, and for the USA the alloy number introduced in all standards (ASTM, SAE, MIL etc.) has been specified. largely in agreement; () partially in agreement. 2 G = sand casting; GZ = centrifugal casting; M = shell mould casting. The values indicated are minimum values ascertained on separately cast test bars in the case of G and M. In the case of GZ, the test bar is taken from the casting; here the specified values apply only for wall thicknesses up to 50 mm. Guarantee values must be agreed. 3 Guideline values 4 Material perfomance sheet Forms of delivery: G: Castings according to provided patterns, max. piece weight 7000 kg. GZ: Centrifugal cast and rough turned bushes/rings from appr. 50 mm bore diameter, max. outside diameter 800 mm, max. length appr. 500 mm. M: Castings according to metal pattern equipment, max. outside diameter 350 mm, max. piece weight 25 kg.
