Shims are products for underlaying and for simultaneously compensating production tolerances.
By underlaying or inserting shims, production tolerances of components can be reduced: when joining components, these shims can reduce or replace processing costs from machining work which would otherwise be necessary. With regard to repair and maintenance, the use of shims reduces the cost of the work required.
Shims can be divided up into many sub-groups:
As well as standard products, parts are also produced according to customer drawings in both areas.
Below is a list of the different product groups and their previous product names:
Scope of product definition
The selection of the base materials and the basic form constitute possible distinctions between these and other shim products.
The base materials are usually strip stock made of metallic materials. The forms of the parts are adapted to the stamping technique. This means that highly intricate structures such as those produced by laser processing or chemical caustic processes are not possible.
In general, all separation methods can be used to manufacture shims. At Georg Martin GmbH, the favoured methods are a combination of shear separation, stamping and nibbling.
