The Global Landscape of Car Weather Stripping

In the modern automotive industry, weather stripping is no longer just about keeping rain out. It has evolved into a critical component for NVH (Noise, Vibration, and Harshness) control, aerodynamics, and thermal management. The global market for automotive sealing systems is projected to grow significantly as vehicle manufacturers prioritize cabin silence and energy efficiency.

From the bustling factories in Germany to the tech-driven assembly lines in China, the demand for high-performance elastomers like EPDM, TPV, and advanced Silicone has reached an all-time high. Global Tier-1 suppliers are now looking for partners who can offer more than just a product—they need material science expertise and rapid prototyping capabilities.

Shenzhen 101 Electronic Technology Co., Ltd.

Precision Silicone Components Manufacturer | Since 2007

With 17 years of dedicated expertise, Shenzhen 101 Electronic Technology Co., Ltd. is a leading manufacturer of precision silicone components, serving as a trusted partner for industries that demand high-performance sealing and structural solutions. Established in 2007 and certified to both ISO 9001 and IATF 16949 standards, our company operates from an 8,000㎡ state-of-the-art facility equipped with advanced production lines.

We specialize in integrating innovations in material science with precision molding technologies to deliver critical silicone rubber parts that enhance the reliability of products across the automotive, consumer electronics, medical devices, and industrial equipment sectors.

Production Facility

Advanced Core Production Capabilities

Our production infrastructure is designed to meet complex silicone manufacturing demands through a combination of heavy-tonnage molding systems and intelligent automation:

  • Heavy-Tonnage Molding Systems: We operate a comprehensive range of compression presses (250T to 600T) for large-format silicone parts, as well as injection molding machines (350T to 550T) capable of processing both Liquid Silicone Rubber (LSR) and High-Temperature Vulcanized (HTV) silicone.
  • Dimensional Stability: Each machine is equipped with automated demolding systems to ensure dimensional stability within ±0.15mm—essential for applications where precision is critical to product safety and performance.
  • Material Expertise: With over 40 proprietary silicone formulations, we meet diverse functional requirements including conductive silicone (10³–10⁸ Ω·cm) for electromagnetic shielding, food-grade silicone (FDA compliant), and flame-retardant silicone (UL94 V-0 rated).
