High-precision biocompatible custom medical rubber components and device seals.

High-Precision Medical Rubber Components

We manufacture cleanroom-molded, high-quality medical rubber components engineered for sensitive healthcare devices and life-science applications. Formulated using pure platinum-cured silicone, these parts meet strict biocompatibility standards, feature zero toxicity, and withstand continuous autoclave sterilization cycles.

Durable and customizable printed custom silicone keypads for electronics.

Custom Silicone Keypads & Elastomeric Switches

Our secondary finishing and custom molding lines produce durable, customizable silicone rubber keypads for high-cycle electronic devices. We integrate customized tactile push forces, screen-printed graphic layouts, backlit windows, and protective PU coatings to ensure complete symbol durability over millions of operations.

Precision Metal Dome Keypad Assemblies

We design and manufacture high-performance metal dome assemblies that provide immediate tactile feedback inside custom elastomeric switch interfaces. Our manufacturing team structurally integrates premium stainless steel domes beneath silicone outer buttons to deliver clean, physical switch action and electrical reliability.

Co-molded and overmolded custom rubber to plastic bonded components.

Multi-Material Rubber-to-Plastic Bonding & Overmolding

We specialize in manufacturing combined rubber-to-plastic bonded parts and overmolded assemblies for complex industrial machinery. By chemically or mechanically locking elastomeric seals onto rigid plastic chassis substrates, we deliver robust, leakproof, and vibration-dampening components that reduce final assembly steps for our clients.

Flexible custom rubber extruded tubing for automotive and medical operations.

High-Performance Custom Rubber Extruded Tubing

Our extrusion lines fabricate high-tolerance custom rubber extruded tubing tailored for medical, industrial fluid handling, and automotive transfer lines. We extrude premium EPDM, Nitrile (NBR), and high-purity Silicone profiles that resist severe ozone, chemical exposure, and high temperatures.

Custom extruded rubber profiles showing varying channel designs and shapes.

Flexible Extruded Rubber Profiles & Sealing Gaskets

We manufacture a comprehensive line of flexible extruded rubber profiles, cords, and channel seals. Engineered for complex outdoor enclosures, cabinet insulation, and impact protection, our custom profiles provide a robust, watertight barrier that holds up under extreme mechanical compression.
