Laminated Shims Overview

The LAMECO laminated shim can be easily peeled with a simple scalpel.

LAMECO Laminated Shims, also called Peel Shims, Peelable Shims or Peel-Off Shims, are designed with special materials which have the property of being easily peelable into thin strips of a few thousandths of an inch.

They are used to precisely fill space between components, to achieve the truest possible fit within mechanical assemblies.

Any complex mechanical assembly suffers from the accumulated faults created by machining tolerances. This is why clearances of several thousandths of an inch will be found once the assembly is completed. These clearances must be compensated in order for the assembly to fulfill its intended function.
Before the invention of laminated shims, technicians could only resort to one of two methods, which today Lameco has rendered obsolete, to correct unacceptable clearances:

Grinding of adjustment shims	Stacking of solid shims
Principle: after measuring the clearance needing to be compensated, the technician resorts to a grinding process in order to manufacture 'adjustment shims'. Disadvantage: this process is wasteful of time, money, and resources. It requires the purchase of a grinding machine, and the use of highly skilled (and costly) technicians. It also adds an extra stage to the manufacturing process.	Principle: starting as before - and measuring the clearance needing to be compensated, technicians stack thin metal sheets, inserted with difficulty into often almost inaccessible places. Disadvantage: this method risks dangerous imprecision. Due to residual matter such as dust, grease and material chips which get in during the creation of the stack, any precision of the end result becomes very hit and miss.

Laminated shims are invaluable design and assembly tools that replace the inefficient techniques of the past to achieve superior accuracy.
