Product Overview

Wear Resistant Shock Valve Shim for Hydraulic Shock Absorbers

XIAYI's shock absorber valve shim is engineered for maximum wear resistance in demanding hydraulic environments. This stamped metal washer serves as a critical flow control element within shock absorber valving systems, precisely metering hydraulic oil passage to deliver consistent, tunable damping performance across the full range of operating conditions.

The carefully selected material composition and specialized surface finishing create a shim that maintains its dimensional integrity and surface quality even under continuous high-pressure oil flow, translating directly to extended shock absorber service intervals.

Frequently Asked Questions
What is the function of a valve shim in a shock absorber?
Valve shims (also called valve discs or spring washers) are thin, precision-stamped metal discs that form the valving stack inside a shock absorber. They flex under hydraulic pressure to control oil flow between chambers, directly determining the damping force characteristics. By stacking shims of different thicknesses and diameters, manufacturers can tune compression and rebound damping curves precisely.
What materials are available for valve shims?
XIAYI offers SK4 and SK5 carbon tool steels, 65MN spring steel, CK101/C100S high-carbon steels, SUS stainless steel grades, and 20C low-carbon steel. Material selection depends on the application's requirements for strength, fatigue life, corrosion resistance, and cost targets.
What thickness range and tolerances can XIAYI achieve?
XIAYI manufactures valve shims from 0.1mm to 3.5mm thickness (up to 10mm for certain configurations) with precision tolerances. Our laser measurement systems and statistical process control ensure consistent thickness across production batches for predictable damping performance.
What is the difference between stamping and fine blanking for valve shims?
Conventional stamping cuts material by fracture, leaving rough edges with burrs. Fine blanking uses a triple-action press to produce fully sheared, smooth edges with minimal rollover and no burrs — critical for preventing stress risers and ensuring consistent oil flow patterns.
What is the minimum order quantity (MOQ) for custom valve shims?
MOQ varies based on specifications. With over 3,500 existing mold configurations, common sizes can be produced with minimal setup. For new custom designs, our engineering team provides a quotation including tooling development timeline and per-piece pricing.
What quality certifications does XIAYI hold?
XIAYI is IATF 16949:2016 and ISO 9001:2008 certified. We provide material certifications, dimensional inspection reports, hardness testing data, and flatness verification. FAIR and PPAP documentation are available to support OEM qualification requirements.
How do you ensure consistent flatness across production batches?
Flatness is verified through incoming material inspection, in-process monitoring, post-process laser flatness scanning, and final QC sampling. Shims not meeting specified flatness tolerance are rejected. For extremely tight requirements, additional precision grinding or roller leveling can be incorporated.
Can XIAYI provide custom heat treatment for specific hardness requirements?
Yes. XIAYI offers quenching and tempering, austempering, and martempering to achieve specific hardness, toughness, and elastic properties. Heat treatment is tailored to the material grade and operating conditions, validated through hardness testing and metallurgical analysis of each batch.
