Company News

As a national high-tech enterprise with a decade of deep expertise in the rubber and plastic field, Shenzhen Donglan Rubber & Plastic Technology Co., Ltd. has always been driven by technology and centered on quality. In the silicone products sector, we have established a high-end smart manufacturing system that integrates research and development, design, and production. With advanced equipment, mature processes, and full-process quality control capabilities, we continuously provide global customers with high-precision, high-performance silicone solutions.

Core Manufacturing Capabilities – Setting the Benchmark for Silicone Smart Manufacturing

Fully Automated Intelligent Production Lines

The company has introduced world-leading silicone production equipment, including fully automated vacuum vulcanizing machines, precision injection molding machines, and high-precision mold processing equipment. This enables fully automated production from raw material mixing and molding vulcanization to post-processing. Through intelligent control systems, we ensure product dimensional accuracy of ±0.05mm, meeting the stringent requirements for silicone products in fields such as medical and electronics.

Precision Mold Development Capabilities

With an in-house mold R&D center equipped with CNC machining centers, 3D precision measuring instruments, and other advanced tools, we can quickly respond to customer needs and develop complex silicone molds (e.g., multi-cavity molds, stacked molds). Our molds have a lifespan exceeding 500,000 cycles, ensuring efficiency and stability in large-scale production.

Multi-Process Coverage to Meet Diverse Needs

Compression Molding: Suitable for standard components such as sealing rings, buttons, and shock-absorbing pads, with customizable features like high-temperature resistance (-50°C to 250°C) and anti-aging properties.

Liquid Silicone Rubber Injection Molding (LSR): Used for highly transparent and clean products like medical catheters, baby products, and precision electronic components, delivering burr-free and residue-free results.

Extrusion Molding: Produces long-dimension products such as silicone tubes and custom-shaped sealing strips, supporting food-grade and medical-grade certified raw materials.

Full-Process Quality Control System

From raw material intake to finished product delivery, we strictly adhere to ISO 9001, ISO 13485 (medical), and IATF 16949 (automotive) quality management standards. Equipped with advanced testing devices such as spectrum analyzers, tensile testing machines, and airtightness testers, we ensure that product performance meets customer specifications 100%.

Technical Advantages – Empowering Industry Innovation

Material Modification Technology

Through techniques like nano-modification and blend reinforcement, we have developed specialized materials such as antibacterial silicone, conductive silicone, and high-tear-resistance silicone, breaking through the limitations of traditional performance.

Medical and Food-Grade Certifications

Our products have passed international certifications such as FDA, LFGB, and ROHS, making them widely applicable in safety-sensitive fields like medical devices, baby products, and food packaging.

Green Smart Manufacturing

By adopting eco-friendly silicone raw materials and low-energy production processes, we help customers achieve sustainable development goals.
