Over 20 Years of Focused Spring Washer Manufacturing

Hangzhou Huiying Spring Washer Co., Ltd. has operated continuously as a specialized production facility in Hangzhou, China. Our operations remain centered entirely on manufacturing split lock, wave, and conical washers for machinery and fastener buyers worldwide, adhering strictly to verifiable engineering standards without relying on unverified claims or invented statistics.

Every production run follows disciplined workshop routines covering raw material selection, precision stamping, heat treatment, and final dimensional verification. Our technical team checks tolerances and spring performance to ensure consistency across standard and custom batches.

Quality control procedures are integrated into every stage of manufacturing to verify that thickness, outer diameter, and inner diameter meet specified technical requirements before packaging and export.

We coordinate directly with overseas distributors, importers, and OEM buyers to review drawings, confirm specifications, and manage production schedules efficiently. Clear communication ensures that technical requirements for non-standard or custom washers are understood before tooling begins.

Packaging and shipment preparation are handled with careful attention to secure export standards, ensuring products arrive ready for integration into industrial machinery and fastener assemblies.
