Shenzhen Xunzhi Building Material Industry Co., Ltd. Factory Tour

At Shenzhen Xunzhi Building Materials Industrial Co., Ltd., we operate a modern and efficient production facility equipped with advanced machinery and strict quality management systems. Our factory integrates R&D, mixing, extrusion, cutting, molding, adhesive application, and inspection into a streamlined manufacturing process that ensures consistency, precision, and high output.

Key Production Capabilities:

• Extrusion Lines:

  We operate multiple automated rubber and plastic extrusion lines capable of producing EPDM, PVC, silicone, Santoprene, and dual-hardness co-extruded sealing strips. These lines support both standard and customized profiles for doors, windows, curtain walls, and vehicles.

• Injection Molding Machines:

  Our facility includes precision injection molding equipment for producing molded rubber parts, corner joints, and rubber-plastic combination components. This supports high-accuracy parts with complex geometries.

• Mixing & Compounding:

  Our in-house rubber compounding system ensures material consistency, allowing us to control performance characteristics such as hardness, elasticity, UV resistance, and flame retardancy from the very beginning.

• Adhesive & Tape Application:

  For EVA single- and double-sided adhesive seals, we use automatic gluing and tape laminating machines, ensuring strong adhesion and uniform application—ideal for easy installation on glass and metal frames.

• Cutting & Trimming:

  Precision cutting equipment allows for clean edges, consistent lengths, and customized packaging based on client specifications.

• Quality Control Station:

  Every production batch undergoes strict quality checks including hardness testing, tensile strength, weather resistance, compression set, and dimensional accuracy to meet international standards.

With a skilled technical team and lean production management, Xunzhi delivers high-volume orders with fast turnaround while maintaining the flexibility to handle small-batch customization. Our monthly capacity reaches millions of meters of sealing strips, enabling us to serve clients in diverse sectors including construction, automotive, rail transit, and industrial manufacturing.
