Bespoke and Custom Rubber Components for Automotive and Plastic Applications

In today's precision-driven manufacturing environment, the demand for custom rubber components and custom automotive rubber parts continues to grow. The synergy between rubber and plastic components represents a key engineering partnership that provides innovative solutions for challenging applications.

Hongsinn specializes in developing high-precision rubber components using advanced CNC machining and custom tooling. Our equipment is capable of processing both flexible compounds and rigid elastomers, suitable for both low-volume prototypes and high-volume production.

Leveraging years of practical experience, we provide precision-machined O-rings, seals, gaskets, bumpers, and vibration isolators. We maintain a ±0.05 mm tolerance and consistent quality even when machining complex geometries and multi-material parts. This high standard of precision and quality enables us to meet our customers' stringent requirements for rubber components.

What is Rubber CNC Machining?

Hongsinn's rubber CNC machining involves the high-precision removal of material from vulcanized or thermoplastic rubber using specialized CNC lathes and milling machines optimized for elastomeric materials. Unlike molding or extrusion processes, our machining method starts with a solid rubber blank, enabling superior dimensional control.

We utilize custom fixtures and high-speed tooling to prevent deformation or tearing of the flexible substrate. This approach enables us to consistently deliver parts with tight tolerances, repeatable performance, and complex geometries, making it particularly suitable for the manufacture of critical seals, dampers, and high-performance rubber components.

Different Rubber Properties

Elasticity
Ideal seals and dampers, our rubber parts maintain flexibility and high dimensional accuracy.

Tensile Strength
We process strong rubbers like nitrile rubber to handle dynamic loads without tearing.

Tear Strength
Our components offer excellent resistance to tearing and flex fatigue, ensuring a longer service life.

Wear Resistance
We use tough compounds like neoprene and polyurethane (PU) to produce wear-resistant rollers and pads.

Chemical Resistance
EPDM, VITON, and other rubbers enable precision processing in harsh chemical environments.

Thermal Stability
Silicone and FKM parts can withstand temperatures up to 250°C, making them ideal for high-temperature applications.

Electrical Insulation
We process dielectric rubbers for secure, precise components in electronics and moisture-sensitive systems.

Weather and Ozone Resistance
EPDM parts are UV, ozone, and moisture-resistant, making them ideal for outdoor and HVAC applications.

Compression Set Resistance
Our seals maintain their shape and function under long-term pressure and heat.
