PVC TPU TPE Seal Profile Extrusion Line

Achieving consistent quality in sealing strips is one of the biggest challenges for manufacturers in the construction and automotive industries. Variations in hardness, deformation caused by excessive shear, and unstable extrusion speed often lead to sealing products that fail under real-world conditions. The PVC TPU TPE Seal Profile Extrusion Line is engineered to eliminate these pain points by delivering stable output, low melt temperature, and smooth processing for a wide range of sealing materials. Whether you produce door and window seals, automotive weatherstrips, or custom industrial sealing solutions, this profile extrusion line offers a reliable and scalable platform for long-term production.

Developed with both European and domestic advanced extrusion technology, the PVC TPU TPE Seal Profile Extrusion Line is built for high-performance thermoplastic sealing profiles. It supports PVC, TPU, TPE, TPR, TPV and other elastomeric materials, with optional co-extrusion modules for multi-layer sealing structures. The combination of a professional screw design, low-shear processing, SIEMENS PLC control, and energy-efficient operation enables the extrusion machine to maintain stable melt flow, precise temperature regulation, and excellent surface finish across all seal profile types.

High-stability extrusion for complex sealing materials
Purpose-designed screws ensure low shear and controlled melt temperature, preventing over-plasticizing and improving dimensional stability of every seal profile.

Flexible configuration for diverse applications
Supports single-layer and co-extruded sealing strips. Different L/D ratios and compression ratios are available to match PVC, TPU, TPE, TPR, and TPV processing requirements.

Reliable automation & user-friendly operation
Equipped with SIEMENS PLC, smart touchscreen interface, imported AC inverter, and RKC temperature controllers for accurate control and easier maintenance.

Low energy consumption, high output
Optimized screw geometry and durable alloy steel components increase throughput while reducing operating costs-ideal for continuous industrial production.

Durable structure with long service life
Screws and barrels are made from high-performance alloy steel, providing superior wear resistance, corrosion resistance, and long-term reliability.

What is a sealing strip?

A sealing strip is a functional profile designed to block water, air, dust, noise, or vibration. It plays a crucial role in insulation, waterproofing, shock absorption, and improving structural integrity.

What types of sealing strips can be produced?

The extrusion line covers door seals, window seals, decorative strips, glass seals, automotive weatherstrips, luggage box seals, engine hood seals, and more.

Why choose thermoplastic sealing materials like PVC, TPU, TPE ?

They offer excellent weather resistance, anti-aging performance, corrosion resistance, and elasticity-especially important for doors, windows, and automotive systems.
