In the highly engineered automotive manufacturing industry, custom automotive rubber parts are critical, specialized components that ensure vehicle safety, performance, and longevity. The custom rubber component production process enables manufacturers to create custom rubber components that meet the exacting specifications of a variety of automotive applications.

Natural Rubber (NR)
Natural rubber has excellent elasticity and tensile strength, making it an ideal choice for components subjected to dynamic stress, vibration, or repeated flexing. Hongsinn processes NR into durable, vibration-absorbing components such as bushings, isolators, and industrial dampers, ensuring consistent performance in high-motion applications.

Nitrile (NBR)
Nitrile rubber is known for its superior resistance to oils, fuels, and greases, making it particularly suitable for automotive and industrial gaskets, seals, and hoses. Our CNC machining process ensures that NBR components from TOPS maintain structural integrity and mechanical properties in harsh chemical environments.

Ethylene Propylene Diene Monomer (EPDM)
EPDM excels in resistance to weathering, UV rays, ozone, and high temperatures, making it a top choice for outdoor sealing applications. We process EPDM into automotive weatherstripping, roof membranes, and water system components, providing durable weatherproofing in demanding environments.

Silicone
Silicone offers excellent flexibility, heat resistance, and solvent resistance. Hongsinn specializes in machining medical-grade and food-grade silicone components that meet stringent biocompatibility and hygiene requirements for a wide range of applications in the aerospace, healthcare, and food processing industries.

Fluorocarbon (FKM)
Viton is designed for extreme environments, offering excellent chemical resistance and temperature stability up to 250°C. We machine Viton parts for the aerospace, chemical processing, and oil and gas industries, where heat, pressure, and corrosive fluids demand perfect sealing performance.

Chloroprene (CR)
Chloroprene offers a balance of oil resistance, mechanical durability, and weather resistance, making it a versatile material. Hongsinn precision-machines gaskets, protective covers, and HVAC components made of neoprene, providing reliable performance both indoors and outdoors, even in challenging industrial conditions.
