Custom Thin Stainless Steel Shim Sheets for Industrial Assembly & Gap Adjustment
Metal shims are precision-engineered thin metal spacers used to fill small gaps or adjust alignment between parts. At Shenzhen Xinhaisen Technology, we produce high-accuracy etched metal shims for industries such as automotive, aerospace, medical devices, electronics, and mechanical assemblies. Our shims offer consistent thickness, burr-free edges, and tight tolerances for reliable performance.
We use photochemical etching (chemical milling) to manufacture metal shims:
Material cleaning – Raw metal sheets are thoroughly cleaned.
Lamination & exposure – Photoresist film is applied and exposed with precise shim patterns.
Development – Unexposed areas are removed, revealing the metal.
Etching – Chemical etchant dissolves exposed areas to create shims with high precision.
Stripping – Remaining photoresist is stripped away.
Inspection & packaging – 100% quality check before shipment.
This process produces burr-free, stress-free shims without heat or mechanical impact.
High precision – Tolerances down to ±0.01mm
Ultra-thin capability – From 0.02mm to 1.5mm thick
Fine detail – Minimum hole diameter 0.03mm, line width 0.015mm
No burrs or edge deformation
Consistent thickness across large or small batches
Suitable for prototypes and mass production
