Targeting different media (oil, water, gas, chemical reagents), temperature ranges (-50℃~200℃), and pressure conditions, we set up dedicated R&D teams to provide end-to-end customized services from seal structure design, material selection to prototype trial production. We solve core pain points such as high wear resistance, leakage prevention, and anti-aging.

We optimize core processes including molding, injection molding, and vulcanization, enhancing product weather resistance, adaptability, and service life to meet the rigorous requirements of high-end equipment for seals.

Equipped with a professional R&D and testing laboratory, we own core testing instruments such as oil seal fatigue test equipment, tensile testing machines, and Akron abrasion testers. We conduct comprehensive verification on product indicators including sealing performance, tensile strength, wear resistance, and medium corrosion resistance, ensuring the stability and reliability of R&D results.

Introducing core equipment such as high-precision trimming machines and CNC machining equipment, we adopt a standardized process of "Raw Material Pretreatment - Precision Molding - Secondary Vulcanization - Precision Machining". We strictly control the process parameters of each production step to ensure product dimensional accuracy and consistency.

With an annual production capacity of 18 million pieces (sets), we can undertake bulk orders and rush orders. Combined with efficient supply chain management, we achieve rapid order response and on-time delivery to meet customers' mass production needs.

We have established a full-process quality traceability mechanism, covering incoming raw material inspection, in-process patrol inspection, and final outgoing product inspection. Each batch of products records production batches and testing data to ensure zero outflow of unqualified products, complying with the ISO9001 quality management system standards.

R&D teams dive deep into the production frontline, rapidly transforming laboratory technologies into mass production processes to ensure the manufacturability and cost controllability of customized products.

We select high-quality raw material suppliers from home and abroad, implement comprehensive control over the production process, and all products pass multiple rigorous tests such as pressure resistance, temperature resistance, and wear resistance.

Our product range includes oil seals, O-rings, gaskets, mechanical seals, and other full-series products, adapting to multiple fields such as automotive engines, industrial pumps and valves, construction machinery, and hydraulic equipment, providing one-stop sealing solutions.
