Thin Gauge Shock Valve Shims for Precise Hydraulic Control

Q: What is the thinnest shim you can reliably produce?

Our standard minimum thickness is 0.5mm with consistent quality. We have produced thinner gauges for specialized applications — please contact our engineering team to discuss feasibility for your specific requirements, including material grade and diameter constraints.

Q: How do you prevent warping or deformation in thin gauge shims?

We use precision-guided stamping tools, controlled feed rates, and optimized clearance settings specifically calibrated for thin materials. Post-stamping, shims undergo flatness inspection. For ultra-thin applications, we can recommend material grades with inherently better dimensional stability after processing.

Q: What is the typical tolerance on a 0.5mm thin shim?

Standard thickness tolerance is ±0.03mm, approximately 20% of material thickness. Tighter tolerances are achievable through secondary processing — please specify your requirements during the RFQ stage for a capability assessment.

Q: Can thin gauge shims be combined with thicker shims in the same stack?

Absolutely. Many damper tuning strategies employ a graduated shim stack where thinner shims at the piston face provide initial low-speed sensitivity, transitioning to progressively thicker shims for high-speed blow-off control. We can supply complete shim stack kits to your specification.

Q: Do you provide shim stack tuning consultation?

While the final damping curve is your design responsibility, our application engineers can discuss material behavior characteristics and stack configuration best practices based on extensive production experience. We also offer sample kits for empirical testing.
