AI-Powered supplier vetting

SummaryLiuzhou Pinmo Sealing Sci-Tech Co., Ltd. presents broad manufacturing and technical-service capabilities, including OEM for recognized brands, ODM services, product customization, and stated experience across multiple international markets. Its management certifications include TS 16949, ISO 14001, ISO 9001, and SA 8000. The supplier reports inventory capability, standardized finished-product inspection instructions, and lead times within 15 working days in both peak and off-peak periods. However, evidence is incomplete regarding after-sales support, financial strength, customer references, and contract status. The supplier lacks an SDK, overseas warehouses, overseas showrooms, overseas agents or branches, and reported participation in offline trade shows. It also reported no regular fire drills during the past year.

Supplier typeThe stated business scope covers technical services, technology development and transfer, seals, plastic and rubber products, mechanical parts, glass-fiber-reinforced plastic products, and auto parts. The supplier also describes a factory, broad product range, and worldwide industry service, indicating a manufacturer with technical-service capabilities rather than a narrowly focused trading profile.

CertificationsThe supplier reports holding TS 16949, ISO 14001, ISO 9001, and SA 8000 certifications. These explicitly indicate coverage of automotive quality management, environmental management, quality management, and social accountability systems.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has R&D engineers with total experience in the stated 6–10 range. However, it reports no available SDK, so its innovation support is demonstrated through product development and ODM rather than software-development integration.

Production capacityThe supplier reports inventory capability, finished-product inspection instructions that are uniformly followed, annual output information of 10,000,000 sets, and lead times within 15 working days in both peak and off-peak seasons. Its manufacturing capacity is therefore explicitly supported, although the manufacturing-contract status is unknown.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and minor customization. It also reports ODM service availability, providing direct evidence of multiple customization routes.

Product Q&A

Q:What is the main difference between a USH seal and a UPH seal?

The primary difference lies in the cross-section. The USH seal features a significantly smaller section than the UPH type, making it the ideal choice for applications with narrow integrated grooves where space is limited, while still providing excellent general-purpose sealing for both pistons and rods.

Q:Can this single USH packing truly be used for both piston and rod sealing?

Absolutely. The USH is designed as a universal U-cup packing. Its symmetrical or near-symmetrical lip structure allows it to work effectively as a piston seal on the inner diameter and as a rod seal on the outer diameter in light to medium-duty hydraulic circuits.

Q:What material is the standard USH packing made of, and what are its operating limits?

Our standard USH seals are molded from high-performance polyurethane (PU) with a typical temperature range of -30C to +100C and a pressure rating up to 400 bar when used with proper backup rings. Custom materials such as NBR or FKM are also available for special fluids or higher temperature requirements.

Q:How should I correctly install a USH seal into an integrated groove?

Ensure the hardware groove is clean and burr-free, then apply a light coat of system oil to the seal. Because of its compact section, the USH can be gently snapped into place by hand. Just make sure the sealing lips face the pressure side, and avoid twisting the packing during installation to ensure a perfect static and dynamic seal.
