Custom stainless steel shims are designed to meet specific engineering requirements for spacing, alignment, and tolerance adjustment. As an OEM precision shim manufacturer, we provide fully customized solutions based on drawings or technical specifications. From ultra-thin shims to complex shapes with holes and slots, our custom shims ensure high accuracy, consistent quality, and reliable performance for industrial and precision applications.

What Is a Custom Shim

A custom shim is a precision metal spacer manufactured according to specific design requirements, rather than standard sizes. It is widely used in assemblies where unique shapes, thicknesses, or structures are required.

Custom shims can include:

• Special outer shapes 
• Inner holes or slots 
• Multi-hole patterns 
• Ultra-thin thickness 

👉 Ideal for OEM projects and non-standard applications.

What We Can Customize

We support a wide range of customization options:

✔ Thickness

• From 0.01mm to 1.0mm 
• Tight tolerance control available 

✔ Shape & Structure

• Round / square / irregular shapes 
• Slotted shims for easy installation 
• Notched or tab shims for positioning 
• Multi-hole designs 

✔ Material

• Stainless Steel 304 / 316 
• Brass / Copper (optional) 

✔ Surface & Quality

• Burr-free edges 
• High flatness 
• Clean surface finish 

👉 Suitable for both simple and complex shim designs.

Custom Shim Manufacturing Process

We select the most suitable process based on your design:

• Chemical Etching → Best for ultra-thin and complex shapes 
• Laser Cutting → Fast and flexible for medium thickness 
• CNC Machining → Suitable for thicker precision parts 

👉 Etching is especially recommended for high precision and intricate geometries.

Custom Order Process

We provide a clear and efficient OEM process:

Step 1 – Inquiry

Send us your drawing (DWG/DXF/PDF) or specifications
