Supplier typeThe supplier is a Guangzhou-based manufacturer specializing in construction-machine sealing products, with integrated seal R&D, production, and service. Its stated product scope includes hydraulic seals, O-rings, PU seals, dust seals, wear rings, and backup rings.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaints, and supplier-service assessment. However, it reports no overseas showroom, overseas agent or branch, overseas service coverage, or offline trade-show participation, limiting evidence of international on-site support.

R&D capabilityThe supplier does not provide an SDK or 3D software design service and reports no new products in the previous year. Although it offers ODM services and minor or flexible customization, the explicit evidence does not demonstrate strong recent product innovation.

Production capacityThe factory uses mould-center, CNC, sintering, and vacuum-thermoforming equipment and produces multiple seal categories. It reports substantial annual quantities for backup rings, O-rings, hydraulic seals, and piston seals, supporting established manufacturing capability.

Customization capabilityThe supplier explicitly offers minor customization and flexible customization through its design and R&D capability, and also provides ODM services. It does not provide 3D software design services, so customization is supported but not evidenced as fully digital or highly advanced.
