Welcome to Dezhengkai. We are a leading manufacturer specializing in the design, engineering, and production of custom silicone rubber products, precision silicone gaskets, and durable rubber washers. We transform your unique specifications into reliable, high-quality sealing and insulation solutions to meet the most demanding application requirements.

Whether you need a single prototype or high-volume production runs, we are your one-stop shop for custom-molded rubber components.

We engineer solutions for a vast range of industries, including Automotive, Aerospace, Medical, Food & Beverage, Electronics, HVAC, and Industrial Machinery.

Complex Profiles & Shapes: From bellows and boots to keypads, connectors, and shock absorbers.

Seals & O-Rings: Custom sizes and cord shapes for static and dynamic sealing.

Insulators & Bushings: Electrical and thermal insulation components.

Diaphragms & Valves: Precision parts for fluid and air control systems.

Consumer & Lifestyle Products: Kitchenware, utensils, wearable items, and more.

Sheet Gaskets: Die-cut or waterjet-cut from silicone sheets (various hardnesses and thicknesses).

Formed-in-Place (FIP) Gaskets: Precise, adhesive-backed gaskets applied directly to housings.

Sponge & Solid Silicone: Choose from closed-cell sponge for compressible sealing or solid silicone for robust applications.

High-Temp & Flame-Retardant: Gaskets designed for extreme environments.

Standard & Non-Standard Sizes: Beyond AS568 standards, we make any ID/OD/thickness.

Various Elastomers: Not just silicone! We also work with EPDM, Nitrile (NBR), Neoprene, Viton® (FKM), and Natural Rubber.

Flat Washers, Spacers, & Sealing Rings: For distributing load, preventing leakage, and vibration damping.

• Unmatched Material Expertise: Select from food-grade, medical-grade, conductive, high-temperature (up to 300°C/572°F), and FDA-compliant silicones and rubbers.
• Precision Manufacturing: Tolerances as tight as ±0.01mm achievable with our advanced molding capabilities.
• Cost-Effective at Any Volume: Optimized processes for both low-volume (no minimum order) and high-volume runs.
• Rapid Turnaround: From prototype to production in as little as 2-4 weeks.
• Global Certifications: Compliant with ISO 9001, ISO 13485 (medical), RoHS, REACH, and ULstandards.
