With more than four decades of dedicated expertise, Dalian Bohai Rubber & Plastic Co., Ltd. specializes in the research, development, and manufacturing of rubber and plastic components. Leveraging its mature technological capabilities, stringent quality control, and one-stop custom‑solution services, the company delivers reliable sealing and vibration‑damping solutions across a wide range of industries, including automotive, construction machinery, semiconductors, and automation equipment.
1. End-to-end in-house R&D and production, with proprietary control over core technologies in formulation and tooling. The company has integrated rubber formulation development, mixing, vulcanization and molding, stamping, and die-cutting into a seamless production process. Beyond standard materials such as NBR, EPDM, and silicone, it also offers customized specialty compounds. Leveraging its in-house mold design and manufacturing capabilities, the company swiftly addresses customers’ non‑standard customization and mold‑development needs, thereby shortening project delivery cycles.
II. Automotive‑grade quality management system, with stability rigorously validated by major OEMs. The company has obtained IATF 16949 certification for the automotive industry and has long been a reliable supplier to OEMs such as BAIC and Li Auto, actively participating in the co‑development of component standards. From raw material receipt and in‑process inspections to end‑product aging‑performance testing, the entire process is subject to closed‑loop control, resulting in low failure rates and extended service life.
3. Compatible with multiple materials and operating conditions, covering a diverse range of high- and low-end application scenarios. The product line includes O-rings, sealing gaskets, hole plugs, stop blocks, buffer blocks, dust boots, bellows, bushings, vibration‑damping rubber components, and more. These products meet demanding service requirements such as high‑temperature and low‑temperature resistance, oil resistance, corrosion resistance, and food‑contact cleanliness, while also satisfying the stringent specifications of both domestic and international equipment.
4. Strong R&D capabilities in high‑tech fields, offering end‑to‑end technical solutions. As a national‑level high‑tech enterprise, we are equipped with specialized testing facilities for aging and weathering tests. For demanding operating conditions, we conduct material selection and structural simulation optimization, providing customers with comprehensive technical support—from product selection to final‑product implementation—going beyond mere contract manufacturing.
5. One-stop comprehensive services, catering to both standard and customized needs: We can deliver standardized seals in large volumes while also supporting small‑batch, multi‑specification customizations; this reduces customers’ costs associated with sourcing from multiple suppliers and enables centralized procurement of sealing and vibration‑damping components.
Going forward, Bohai Rubber will continue to refine the quality of its rubber products and consistently deliver cost-effective, highly reliable rubber and plastic components to customers across various industries.
