PVC Window Sill Panel Extrusion Mold

This series of PVC windowsill board molds is precision equipment specially designed for the extrusion of windowsill panels used in home and commercial decoration. The finished panels are widely used for windowsills and bay windows in residences, office buildings, shopping malls and other buildings, featuring moisture resistance, wear resistance and easy cleaning.

The mold body is made of high-quality 3CR17 hot-work die steel, processed by precision CNC machining, vacuum quenching and nitriding treatment. Its surface hardness reaches 28 HRC, providing high wear resistance and corrosion resistance. It can operate stably for a long time under high temperature conditions of 165–205 °C, with a service life more than 50% longer than ordinary molds.

The mold adopts a layered pressure-stabilizing runner design, equipped with an intelligent zoned temperature control system, which ensures uniform distribution of PVC melt, accurately controls the thickness, width and chamfer dimensions of the windowsill board, and avoids defects such as uneven thickness, edge burrs and warping. The cavity strictly reproduces the anti-slip edges, drip grooves and other structures of the windowsill board. The formed windowsill panel features a smooth and flat surface and can be directly installed without secondary polishing.

This mold supports customization of conventional straight and special-shaped chamfered windowsill boards, compatible with general PVC and flame-retardant PVC materials. It can be directly connected to single-screw extrusion production lines, with convenient installation and commissioning. The high versatility of wearing parts greatly reduces production downtime.

Compared with traditional molds, this mold improves molding efficiency by more than 20%. The finished panels feature high dimensional accuracy and good toughness, and can effectively resist rain erosion and daily bumps, making them core equipment for the large-scale production of high-quality PVC windowsill boards.
