Sheet Metal Shim Fabrication
Metal shims are thin metal parts that fill in the narrow gap or spaces between two objects. They can provide support, adjust fit, or extend out the rough surface, among other things. Many industry experts make shims from whatever materials are accessible at the time. Higher-quality metal shims, on the other hand, industrially come in a multitude of materials, including aluminum, copper, brass, lead, nickel, and many others.
At KDM, we offer expertise in designing and producing custom shims for industrial OEMs, energy production, and the petroleum industry. We have decades of work expertise in developing custom raw material solutions; we also have a highly qualified production team and cutting-edge manufacturing equipment. We generate shims in nearly any form, dimension, or complexity.

Shim rings, also known as tolerance rings, are used to establish a firm grip on bearings in embossed, crafted, or worn housing. They are frequently used in conjunction with securing rings to eliminate play between machined parts.

Arbor shims, also called slitter shims, are thin discs used to avoid axial movement in constructed parts. These are machined to certain tolerances for a precise fit. It is used in machinery adjustment uses on rotating blades, saws, and grinding tools.

Slotted shims are available in many patterns and can be used for a variety of uses. Their most unique characteristic is an open, primarily U-shaped slot. They are used as spacers or fastened all over existing bolts and nuts.

There are two types of variable shims: shortened version and lengthened. They are used to increase or decrease the overall length of shoulder bolts (also called stripper bolts or shoulder screws). These are frequently used in punch and die assemblies.

Pre-cut shims are shaped steel parts that are used to raise or lower your machinery in order to maintain shaft alignment. Labeled with their exact thickness, making it simple to determine the shim size required for your needs.
Metal Shim Features

Begin aligning immediately after opening the package. No need to waste time trying to cut your own shims.

All pieces are obviously laser marking of the exact shim thickness. Making it easy to identify the thickness you need.

Offers a higher hardness than standard metal shims on the market. Able to support the heavy load while keeping its thickness.

We offer custom shims made of metal such as stainless steel, brass, etc. It ensures corrosive prevention and long life.

The list consists of common material plating/finishing services that we offer as an extra.
Primer – painting: Shims are commonly painted with primer and finish. We can paint to almost any commercial or military configuration.
Blackening: It is a conversion protective layer that adds mild corrosion protection and appearance. One of its advantages is it does not change the thickness of the shims.
Chemical film: It is a common method of preparing shims for painting.
Anodizing: It is a regular process for aluminum metals. Anodizing improves abrasion resistance while also serving as a surface treatment for paint primers.
Custom Metal Shim for Specific Uses

Metal shims are made of finest grade aluminum materials for motor mount spacing applications. Accessible in different thicknesses ranging from .001” to 0.060”. Its thickness label is color-coded for accurate and easy identification.

Standard U-shaped metal shims are commonly used for aligning shaft and motor. Comes in different thicknesses and can be adjusted. These are used in numerous industries including automotive, power generation, electrical, and so much more.

Steel shims are made of steel that goes between your coil springs and your spring perch. On leaf spring vehicle types, these are used to reconfigure rear axle angles and accomplish appropriate driveline geometric features. They come in different thicknesses for exact fit.

The metal shims are cut into different forms in order to support wear malfunctions. When installed between two machined parts, shims can significantly reduce machining costs. This can lead to increased efficiency gains and cost reductions.
