Company introduction
**Hebei Shuzhi Rubber Products Co., Ltd. - Precision Engineered Sealing & Fluid Transfer Solutions** ### **Core Product Expertise** As a specialist in high-performance rubber components, we deliver critical solutions for automotive and industrial sectors through five core product lines: 1. **EPDM Automotive Sealing Strips** Engineered for doors, windows, trunks, and sunroofs, our EPDM seals offer exceptional resistance to UV, ozone, and extreme temperatures (-50° C to +140° C). Features include integrated metal carriers for structural integrity, low compression set (<25%), and customizable surface finishes (smooth/flocked/coated) to reduce friction and noise. Compliant with ISO 4637 and OEM standards like PV 3341. 2. **NBR Foam Sealing Strips** Designed for oil-rich environments, these closed-cell foam strips serve engine covers, fuel systems, and industrial machinery. With NBR hardness grades from 70A-90A and densities of 150-500 kg/m³, they provide superior resistance to fuels/solvents (<15% oil swell per ASTM D471), effective vibration damping, and IP67-rated sealing. 3. **EPDM Sponge/Foam Sealing Strips** Ideal for HVAC, electrical enclosures, and architectural weatherstripping, our microcellular EPDM foam achieves 35-40 dB sound transmission loss (STC) and maintains watertight integrity with 70% compression recovery. Flame-retardant options meet UL94-HB specifications. 4. **Custom Molded Rubber Components** Utilizing 100-500 ton presses, we manufacture precision O-rings, grommets, vibration mounts, and complex geometries in EPDM, NBR, Silicone, or FKM. Tolerances held within ± 0.1mm (ISO 3302-1) ensure consistent performance in sealing, insulation, and impact absorption applications. 5. **Automotive Water/Coolant Hoses** Reinforced with 3-4 ply fabric/steel wire, our EPDM hoses withstand burst pressures exceeding 600 kPa and temperatures from -40° C to +150° C. Fully compliant with SAE J20 R6/R7/R9 standards for radiator, heater, and coolant systems in EVs and ICE vehicles. --- ### **Manufacturing Excellence** Our **8 specialized production lines** enable vertical integration from raw material compounding to finished products: - **4 Continuous EPDM Extrusion Lines** with laser-guided profile control - **2 Automated Foam Sealing Lines** featuring nitrogen-assisted foaming technology - **1 High-Capacity Molding Unit** supporting multi-cavity tools - **1 Braided Hose Line** with mandrel wrapping precision *Annual Capacity: 14+ million linear meters of seals 500, 000+ molded parts 200, 000+ hose assemblies* --- ### **Quality & Certification** Operating under IATF 16949 and ISO 9001 certifications, we enforce rigorous protocols: - **Material Validation**: FTIR, DSC, and TGA analysis - **Performance Testing**: 1, 000-hour salt spray, thermal aging (135° C/168h), fatigue cycling - **Traceability**: Batch-controlled production with statistical process control (SPC) - **Compliance**: REACH/RoHS, ASTM, SAE, and ISO standards --- ### **Why Choose Shuzhi? ** - **End-to-End Customization**: Profile design (. Dxf/. Dwg support), material compounding (custom hardness/colors/additives), and value-added processing (precision cutting, splicing, packaging) - **Automotive Focus**: IATF 16949-certified processes with OEM audit experience - **Global Reach**: Exports to 30+ countries across Europe, Americas, and Asia-Pacific - **Engineering Partnership**: Collaborative R&D for complex sealing challenges --- **Contact Our Expert Team Today! **
