Laminated Shims

Laminated Shims Overview

Easily peeled laminated shims with a simple scalpel
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.

The advantages of LAMECO laminated shims

LAMECO laminated shims save time, improve on precision, and do away with downtime at the grinding machine. They provide our customers with an excellent quality to price ratio.

  • LAMECO laminated shims can be peeled with scalpel or forefinger (peel shims in INTERCOMPOSITE®, DUOPEEL®, COBRA.X® or X.FIBER®)
  • No need for special tools
  • Quick production line adjustments and field repairs
  • Instantaneous compensation for play or wear and tear without production stoppages
  • Avoids machine reworking
  • Allows level adjustment without taking the machine apart
  • LAMECO laminated shims reduce assembly time
  • Eliminate need for grinding and
  • Eliminate need of solid shims stocks
  • They guarantee optimal precision (which pilings cannot achieve in any way.)
  • They satisfy standards in wide range of industrial machine and assembly line applications.
  • 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.
