A COMPLETE RANGE OF ADJUSTMENT SHIMS FROM LAMINATED PEELABLE TO SOLID SHIMS
Jicey can supply a solution that is perfectly suited to your requirements from its complete range of adjustment shims (peelable, separable, solid, extra-thin and standard), which are available in a wide choice of metal, composite or mixed materials, in any dimensions and all thicknesses (from 0.01 mm for stainless steel).

Alkomposit laminated peelable shims are shims for adjustment made from a composite material. They consist of a stack of basic polyester (Mylar) leaves, joined together by gluing over the whole surface, thereby forming a laminated set of compact appearance. Each basic leaf constituting the stack can be peeled off extremely easily, in complete safety and by hand, until the exact thickness desired is obtained. The shim is therefore perfectly and easily adjusted to compensate accurately for the play in a mechanical assembly. They can satisfy all types of new applications where it is important to introduce concepts of insulation and lightness over a wide range of temperatures. Alkomposit shims can be used advantageously to replace machined or ground solid metal shims.

With dual composition, the thickness is obtained commencing by peeling off the thickest basic leaves, then the fine adjustment is obtained by peeling off the thinnest basic leaves. To optimise the use of dual composition peelable shims, Jicey has developed the Viewtek process. This exclusive and patented process relies on marking the thickness of the basic leaves, written in full, on the central part of the shim. Therefore, because Mylar leaves are transparent, you can see and identify the thickness of the individual leaves you are removing at any time. A colour code makes identification of the various thicknesses (0,025 - 0,05 - 0,1mm) even easier.

ALKOMPOSIT K ™ LAMINATED PEELABLE KAPTON SHIMS     

Les cales pelables Alkomposit existent en polyimide (Alkomposit K pour Kapton). Alkomposit K peelable shims are available in polyimide (K stands for Kapton). Alkomposit shims have physical, chemical and electrical properties (opposite) that are extremely advantageous for all applications in which there are essential requirements for electrical insulation, excellent resistance to chemical agents, high resistance to temperature (from - 70°C to + 400°C), low density (50% of that of aluminium) and also good safety in use. In addition, the use of Alkomposit shims prevents problems of contact corrosion.

Alkomposit peelable shims can be produced in any geometrical shape, by cutting out or machining, to your dimensions and specifications. If the dimensions are large, it is possible to produce shims in several parts, mechanically connected or otherwise. Peelable U shims are also available in standard dimensions.

SHIMPACK ™ SEPARABLE PEELABLE SHIMS       

Shimpack separable shims are adjustment shims consisting of a stack of basic leaves joined together by points of adhesive on the edge. They have the advantage that they can be peeled off very easily by hand, without tools, until the desired thickness is obtained. The applications are mainly shimming of mechanical components that only require medium shimming accuracy.

The use of Shimpack separable shims is especially appropriate in challenging climatic and environmental conditions (public works, heavy engineering, agricultural machinery, etc.). Another advantage is that any basic leaf removed can be reused as an individual shimming item for another adjustment, making it a particularly economical process.

Shimpack separable shims are available in steel, stainless steel or brass and can be made to measure, in any shape to your dimensions and specifications. Shimpack separable shims may consist of basic leaves of the same thickness, possibly with a solid portion. They may also consist of basic leaves of different thickness accessible on one side or the other. In this case, a solid portion may also be added.

SOLID SHIMS AND FOILS       

Strictly made to measure, solid shims, whether ground or otherwise, consist of a close-grained material of predetermined thickness. They are used in all cases in which there are significant stresses (vibration, tension, shear forces, etc.). They are of very high accuracy since they are strictly made to measure and for immediate use on site. They are therefore found in some aeronautical mechanical assemblies such as mountings for equipments mounted on civil and military aircraft engines.

Solid shims are available in a very wide range of dimensions, thicknesses, hardnesses and materials:

• Carbon steels from foils or sheets of 1000 x 1000 or 1500 x 2500 mm (DC03 / DC04 steel with average mechanical resistance, XC75 steel, tempered or not, with strong
• mechanical resistance)
• Stainless steels from foils or sheets of 1000 x 1000 or 1500 x 2500 mm (AISI 304 / 306 / 321 stainless steel)
• Special aeronautical steels from sheets of 1000 x 2000, 5/10ths to 3 mm thick (X17U4 / 15CDV6 steel)
• Aluminium (1050 - 2024)
• Brass (UZ10 / 30 / 33)
• Bronze (UBE2)
• Titanium
• PVC, ABS, Polyester, Kapton, Mylar

EXTRA-THIN SOLID SHIMS       

Individual extra-thin shims are solid shims used to compensate for play that is often less than 1/100th of a millimetre. Made to drawing, in steel, aluminium, stainless steel or polymer, they are produced in thicknesses of 0.025, 0.05, 0.10 and 0.20 mm and even down to 0.01 mm for stainless steel.

Whatever the shape, they are machined and not cut out. Jicey therefore guarantees a high precision part without burrs for very thin shimming.

PEELPACK ™ LAMIPACK ™ SINGLEPACK ™      
STANDARD U-SHAPE ADJUSTMENT SHIMS       

Standard U-shape shims are very often used for the alignment of transmission shafts between an engine and a load. They are available in steel, stainless steel and brass, but also in composite material on request.
