What Are Metal Shims

Metal shims are thin, flat pieces of metal used as spacers or washers between mechanical components to achieve precise alignment or spacing. They are commonly utilized in various high-tech applications where precision is critical. Metal shims help absorb impact, reduce movement or "play," and protect material surfaces from damage.

These shims are manufactured from different types of metals, including stainless steel, aluminum, brass, or copper, depending on the specific requirements of the application. The choice of metal typically depends on factors such as desired strength, corrosion resistance, conductivity, and other mechanical properties needed for the intended application.

Metal shims are widely employed in industries such as aerospace, automotive, electronics, machinery, and manufacturing, where even minor deviations in alignment or spacing can impact the performance and reliability of the equipment or components.

Photolithographically etched metal shims

Photolithography is a highly precise and cost-effective manufacturing process utilized by TMN to tailor metal shims for various applications. TMN offers a variety of material types, including black metals and non-ferrous metal sheets of all grades, along with corrosion-resistant, wear-resistant, and hard-to-etch metals, making them highly suitable for diverse industries.

Our chemical etching advantages

Material Versatility

Thicknesses ranging from 0.03mm to 2.0mm across all metal alloys can undergo photolithography etching.

Ease of Surface Treatment

Photolithography etched shims are readily treated with plating, coating, painting, powder coating, electrophoresis, passivation, deburring, polishing, and brushing.

Cost-Efficiency and Smooth Surface

Compared to stamping, machining, and laser cutting, photolithography etched shims incur no tooling costs, ensuring burr-free, super-smooth, and clean surfaces.

Flexible Designs

Flexible designs including U-shapes, O-rings, and other complex shapes are achievable.

Fast Turnaround

Short delivery times, often within days.

Low Cost

Offers cost-effective manufacturing solutions.
