JinHai possesses professional wire harness customization capabilities. We provide comprehensive solutions encompassing functionality, materials, and application environments. We are confident in meeting your requirements for product functionality, quality, and budget.
- High-temperature environments: Select heat-resistant materials such as silicone rubber or specially formulated cross-linked polyolefin.
 - Chemically corrosive environments: Choose materials with superior acid and alkali resistance, such as PTFE or specially formulated EPDM rubber.
 - Marine environments: Materials must exhibit superior salt spray resistance and waterproofing, with consideration for mold growth prevention.
 - High-frequency electromagnetic signal environments: Employ composite sheath structures with metal braiding layers to ensure signal integrity while preventing external interference.
 -  Mechanical protection design for sheaths varies based on specific application scenarios, such as:
- Crush-exposed harnesses (e.g., vehicle chassis wiring): Sheaths must possess sufficient compressive strength;
 - Outdoor-exposed harnesses: Sheaths require UV resistance;
 - Vibration environments (e.g., agricultural machinery): Sheath materials should exhibit fatigue resistance and be adapted to harness mounting methods.
 
 - Moderate sheath wall thickness provides adequate protection while minimizing costs.
 
Connectors serve critical functions in physical protection and environmental sealing, with material selection tailored to specific application requirements. Common connector materials include:
- PVC
 - Thermoplastic Elastomer (TPE)
 - Chloroprene Rubber (CR)
 - Polyurethane (PU)
 
															- Passenger vehicles, commercial vehicles, and new energy vehicles
 - Industrial equipment manufacturing, automotive manufacturing, and machinery
 - Heavy-duty trucks and construction machinery
