We produce PVC sealing strip production lines that deliver consistently shaped, flexible strips for windows, doors, automotive seals and industrial closures. Our solutions combine controlled extrusion, precision sizing and automated coiling so you get strips with stable cross-section profiles, excellent rebound properties and minimal flash. I collaborate with clients to select the right tooling, shore hardness targets and surface treatments necessary for temperature and chemical resistance.
Why choose our PVC-Sealing-Strip Production Line?
Sealing strips must deliver tight tolerances and long-term elasticity. Our lines emphasize accurate melt temperature control, high-precision calibration and online profile measurement to ensure each batch meets dimensional and mechanical specs. We include options for co-extrusion, foaming or sponge-like cores when improved insulation or compression recovery are required.
Products from these lines are widely used in building envelopes, refrigeration units and vehicle doors. We offer installation support, staff training and spare parts logistics to minimize downtime. For operational details and spare parts lists, review our technical documentation on your product page and then Contact us to request a quote or arrange a factory visit.
PVC sealing strip equipment is mainly used for the production of PVC material sealing strips, achieving large-scale production through extrusion molding technology. Its core equipment includes screw extruders, mold forming systems and cooling devices, which can meet the sealing requirements in fields such as doors and Windows and automobiles.
