LAMECO Laminated shims are designed with special materials which have the property of being easily peelable into thin strips of a few hundredths 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 hundredths 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 observed in the finished assembly:
| The Grinding of Adjustment Shims |
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 totally replace the inefficient machining and grinding of component parts to achieve the required accuracy.
How are laminated shims manufactured?
An extremely fine resin film (in the order of 0.00008” / 0.002 mm) is laid out between the material foils. A combination of enormous pressure and a prolonged thermal treatment bonds the sandwiched materials together.
By this long developed proprietary technique not only is the optimal hardening of the resin is achieved, but also the adhesive film's thickness is reduced to such proportions that it can no longer be measured.
LAMECO laminated shims save time, improve on precision, and do away with downtime at the grinding machine.
