Company Introduction

Located in Shenzhen, China, we are a specialized manufacturer of custom silicone extruded gaskets and seals, offering comprehensive solutions from raw material formulation to precision post-processing. With a strong engineering background and a customer-focused approach, we provide high-performance sealing components tailored to exact application requirements across a wide range of industries.

Professional Silicone Extrusion Manufacturing Process

Our production process combines technical expertise, advanced equipment, and stringent quality control, ensuring reliable performance and dimensional accuracy in every batch.

Material Selection & Formulation

We use high-quality solid and sponge silicone rubber in various grades including platinum-cured, FDA-compliant, UL 94-V0 flame-retardant, and high-temperature resistant (up to 315°C) materials.

Custom formulations are available based on hardness (Shore A), color, tensile strength, elongation, and environmental resistance.

Extrusion Process

Silicone is extruded through precision dies to form custom profiles: D-shape, U-channel, P-shape, hollow tube, solid cord, bulb seals, edge trims, and more.

Co-extrusion and multi-durometer profiles are also available to integrate rigid and flexible elements into a single gasket.

Post-Processing Capabilities

Cut to length , Precision cutting by high speed accurate silicone tube cutting machine

Wind to roll : after silicone tube extruded , Coiling and packaging extruded silicone tubes in continuous rolls for efficient storage and installation

Adhesive Lamination: Laminate extruded silicone strips with double side tapes in good adhesion.

Bond into O Rings: Cutting extrudes silicone tube profiles to length and bond into o rings

Punching holes : Punching silicone strips with fixed hole sizes

Industry Applications

Our silicone extruded gaskets and seals are widely used in:

Automotive & Transportation: Door seals, trunk gaskets, window channels, noise and vibration dampening

LED Lighting: Waterproof gaskets, lens sealing, IP-rated housing seals

Electronics & Enclosures: EMI shielding gaskets, weatherproof and dustproof cabinet sealing

HVAC & Appliances: Thermal insulation seals, compressor door gaskets

Medical & Food Equipment: FDA-grade silicone for sanitary applications in cleanrooms and food processing

Architecture & Construction: Curtain wall gaskets, window glazing seals, expansion joint profiles

Energy & Solar: UV-resistant gaskets for outdoor installations and solar panel framing

Customer Use Cases
