Rubber EPDM Plastic PVC TPE TPV Windows Door Sealing Strip Extruding Production Line

When it comes to sealing strips, we will think of their application in car parts such as doors, windows, bodies, seats, sunroofs, engine cases, and trunk, as well as their waterproof, sealing, sound insulation, dust prevention, antifreeze, shock absorption, and other functions. As a professional enterprise producing sealing strips, we not only delve into every process of mold design, structural manufacturing, processing, assembly, trial molding, trial production, and mass production, but also pay great attention to the design of the sealing strip mold. As sealing strips are applied in different parts of the car, they have different purposes and functions, so the structural design of the mold is also crucial.

The rubber sealing strip production line consists of rubber extruder → Vulcanizing Tunnel → cooling tunnel( can add chiller) → haul off machine → winding machine.

Extruder Use and Maintenance

① The machine head should be assembled together and installed as a whole on the extruder.

② Before assembling the machine head, the grease applied during storage should be wiped off, and the surface of the mold cavity should be carefully checked for scratches, scratches, and rust spots. Necessary polishing should be carried out, and then a layer of silicone oil should be applied to the surface of the flow channel.

③ Assemble the various plates of the machine head in sequence, apply high-temperature grease to the threads of the bolts, and then tighten the bolts and flange.

④ Place the porous plate between the machine head flanges to ensure that it is tightly pressed without overflowing.

⑤ Before tightening the fastening bolts of the connecting flange between the machine head and the extruder, the horizontal position of the mouth mold should be adjusted. The square machine head can be horizontally adjusted, while the circular machine head should be leveled with the bottom surface of the machine head mouth mold based on the fixed model adhesive surface.

⑥ Tighten the connecting flange bolts, tighten the machine head fastening bolts, install the heating ring and thermocouple, and ensure that the heating ring is tightly attached to the outer surface of the machine head.

⑦ Install the set sleeve and adjust it in place. Check if the center line of the host, set sleeve, and traction machine is aligned. After adjustment, tighten the fixing bolts. Connect all water pipes and vacuum pipes of the set sleeve.

⑧ Turn on the heating power and evenly heat the machine head and machine casing. At the same time, open the cooling water at the bottom of the feeding hopper and the gearbox, as well as the inlet valve of the exhaust vacuum pump. When heating, adjust the temperature of each section to 140 ℃ first, and hold it for 30-40 minutes when the temperature rises to 140 ℃. Then, raise the temperature to the normal production temperature.
