FAQ

Here are answers to some of the most common questions regarding shim selection and application.

Q1: What materials are commonly used for precision shims?
The choice of material depends on the operating environment and application requirements. Common materials include:

• Stainless Steel (e.g., SUS304, SUS316): Offers excellent corrosion resistance and durability.
• Brass/Copper: Ideal for electrical conductivity and thermal applications.
• Plastic/PTFE: Used for electrical insulation or low-friction environments.
• Aluminum: Lightweight and suitable for general spacing tasks.

Q2: Can you manufacture custom shims with non-standard shapes?
Yes, we specialize in custom manufacturing. Beyond standard washers and discs, we can produce shims in complex geometries, including squares, rectangles, and custom profiles based on your technical drawings or CAD files.

Q3: What is the thinnest shim thickness you can produce?
For high-precision applications, such as optical systems, we can manufacture ultra-thin shims with thicknesses as low as 0.01mm. We also offer etched shims for intricate, burr-free designs.

Q4: How do I determine the correct tolerance for my application?
Tolerance selection depends on the precision required by your assembly.

• Standard Tolerance: Suitable for general industrial spacing and gap filling.
• Precision/Tight Tolerance: Necessary for sensitive equipment like motors, sensors, and optical devices where minute deviations affect performance.

Q5: Do you offer small quantity orders for prototyping?
Yes, we understand the importance of testing and validation. We support both low-volume prototype orders and high-volume mass production to meet your development and commercial needs.
