QC is name quality control. We pay great attention to QC. QC people is set to keep good quality in each procedure.
Precision designed tooling is the key factor in the quality control of manufactured rubber products. Scheduled tool inspection ensures that proper O-Ring dimension and surface quality is maintained.

All O-Rings are inspected prior to shipment. Every O-Ring must pass a rigorous 1.5 A.Q.L. Such low tolerances are usually reserved for military applications. In addition, all custom molded rubber products receive a 100% dimensional and visual inspection.

Singwax  maintains 100% batch and lot traceability on all rubber compounds produced. To support your quality documentation requirements, you can also request certificates of compliance for your order. In addition, we maintain destructive tests materials, available to you upon request.
