Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for high-quality automotive wiring harness insulation brackets. Since 2017, we have specialized in precision plastic injection molding, offering custom insert molding solutions using PA66 GF30 material. Our brackets are designed to meet the rigorous demands of the automotive industry, providing reliable insulation and mechanical support for wiring harnesses. With a factory spanning 1,000–3,000 square meters and a team of 51–100 skilled employees, we deliver consistent quality and on-time delivery to clients worldwide, including Southeast Asia, Europe, and the Americas.
Our Automotive Wiring Harness Insulation Brackets are manufactured under strict IATF 16949 quality management standards, ensuring every component meets automotive-grade requirements. The use of PA66 reinforced with 30% glass fiber (GF30) provides exceptional strength, heat resistance, and dimensional stability, making these brackets ideal for under-hood and interior applications. The insert molding process allows for the integration of metal or plastic inserts directly into the bracket, eliminating secondary assembly steps and improving overall reliability.
Key Features & Technical Specifications
- Material: PA66 GF30 – high heat deflection temperature (up to 250°C short-term), excellent chemical resistance, and low moisture absorption.
- Insert Molding: Precision overmolding of metal inserts (brass, steel, aluminum) or plastic inserts for enhanced strength, conductivity, or mounting functions.
- Customization: Fully customizable dimensions, hole patterns, rib designs, and insert configurations to match your specific wiring harness layout.
- Surface Finish: Smooth finish as standard; matte or textured options available for anti-glare or aesthetic requirements.
- Durability: Resistant to vibration, impact, and thermal cycling – ideal for long-term automotive use.
- Precision: Tight tolerances (down to ±0.05mm) achieved through advanced mold design and injection molding process control.
