Laminated Shims

A4 - Metric Letter - Inch

Laminated Shims Overview

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 micro ﬁne strips of a few hundredths of a millimeter / of two tenth thousands 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.

Easily peeled laminated shims with a simple scalpel

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

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

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.

Stacking of solid shims

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.

Allows level adjustment without taking the machine apart

Savings

LAMECO laminated shims reduce assembly time
Eliminate need for grinding and
Eliminate need of solid shims stocks

Flexibility

They satisfy standards in wide range of industrial machine and assembly line applications.

Precision

They guarantee optimal precision (which pilings cannot achieve in any way.)

The LAMECO Specialty: Impeccable Quality

Each individual layer of our laminated shims, including all of the laminated shims in our INSTANT-PEEL® range, is bonded to the next across its entire surface and not just at the edges.
Furthermore, thanks to our proprietary production processes, they are perfectly flat and entirely devoid of burrs - whether made of metal or composite material.
