EPDM Sealing Strip Extruder Machine: Efficient PVC Rubber Seals Manufacturing Solution

A production line for manufacturing rubber/plastic sealing strips (EPDM, PVC, PU, TPE). It integrates a single-screw extruder, foaming mould, immersion cooling tank, belt tractor and cutter/winder to produce finished sealing strips for refrigerators, doors & windows, automobiles and similar applications.

The line is designed for EPDM sealing strips and can also produce PVC, PU and TPE sealing strips by changing raw material and extrusion die.

Production flow: raw material → single-screw extruder → foaming mould → immersion cooling water tank → belt tractor → cutter or winder → product inspection & packing.

Production line speed: 2–8 m/min. Total electrical power: about 26 kW. Appearance (footprint): approximately 15 × 1 × 2 m.

A single-screw extruder with a high-efficiency, high-speed screw designed for high output and strong plastification to ensure stable material melting and throughput.

Dies are specially designed for the chosen raw material to provide even discharge, easy adjustment and minimal or no extruding weld marks, resulting in consistent strip geometry and surface quality.

The line uses an immersion cooling water tank for dimensional cooling and a vacuum setting device. All parts that may contact water are made of stainless steel to resist corrosion and contamination.

A two-claw belt-type high-speed tractor is used with stepless frequency speed control to provide stable hauling and match different line speeds and strip profiles.

Yes — the line supports a precise pneumatic cutter or an automatic winder. These can be configured to automatically cut or collect strips to reduce labor and increase efficiency.

Common end uses include sealing strips for refrigerators, doors & windows, automobiles and other industrial sealing applications where flexible rubber/plastic strips are required.

Yes. Extrusion dies/molds are custom-designed for the specific raw material and strip profile. Foaming parameters and moulds can be adjusted for cellular/solid profiles as required.

Regular tasks include cleaning the extruder barrel and screw, checking and tightening die connections, monitoring cooling water quality, changing hydraulic/lubrication fluids per schedule, and inspecting belts, clamps and pneumatic components for wear.

Stainless-steel water-contact parts reduce corrosion and hygiene risks. Standard industrial safety measures (machine guards, emergency stop, safe electrical grounding) should be implemented; additional safety features can be provided to meet local regulations.

Manufacturers typically supply spare parts, installation assistance and training as well as after-sales support. Exact terms (warranty period, spare parts kit, service contracts) depend on the supplier—contact sales for details.

Contact the supplier with your required strip profile, material, desired output speed and any automation options. The supplier will provide a quotation, lead time and can often produce sample strips or run trial production. Lead time varies by customization and order size—please request current delivery estimates from sales.
