What surface finishes are available for your products?

Normally the product surface color is silver (Trivalent Zinc Plating). Black, yellow, red, green, and blue are also available via powder or paint spraying.

How do you handle product quality control?

All products undergo six checks: material inspection, product inspection, routing inspection, inspection before plating, final inspection after plating, and inspection before delivery.

What is your policy on product marking and logos?

Supplier typeThe supplier is a manufacturer and seller of springs, mechanical parts, vibration and noise-reduction equipment, rubber and plastic products, hydraulic machinery components, and related equipment. Its registered business scope indicates a multi-product industrial manufacturer rather than a pure trading intermediary.

After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints, as well as documented corrective and preventive action procedures. This supports an established complaint-resolution process, although the slices do not provide response times, service results, warranty terms, or overseas service coverage.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, indicating ongoing product-development activity. However, it reports no available SDK, and no details are provided on R&D staffing, patents, laboratories, or development resources.

Production capacityProduction evidence includes dedicated winding, grinding, spraying, polishing, and punching facilities, four quality inspectors, documented finished-product inspection instructions, inventory capability, and valid contracts with associated subcontractors. The supplier also reports lead times within 15 working days in both peak and off-season and describes a strict quality system, but the stated monthly production figure is unclear and cannot support a precise capacity assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad product-development and customization support.

Client casesThe supplier states that it provides OEM services to recognized brands and has received positive customer recognition from the seal, automotive and motorcycle, mechanical, electrical, electronics, and appliance industries. No customer names, project descriptions, order scope, or independently verifiable case details are provided.
