UPVC PVC Waterproof Construction Interior Window Extrusion Die Mold
Product Detailed Description
The UPVC PVC Waterproof Construction Interior Window Extrusion Die Mold is a core precision forming equipment specifically developed for modern high-performance energy-saving door and window systems. This mold is widely used in the production of various high-end architectural profiles, perfectly adapting to the high standards required for a UPVC profile extrusion die for construction. As a professional UPVC waterproof frame extrusion die, its design core lies in achieving precise forming of multi-cavity irregular structures. It can extrude complex cross-sections (such as seven-chamber structures) containing air-tight chambers, drainage grooves, and steel reinforcement ribs in a single pass. The flow channel adopts a geometric smooth transition and stagnation-free zone design to ensure uniform wall thickness (meeting national standards ≥2.8mm) and consistent dimensions of sealing strip slots, laying a solid foundation for the excellent waterproof and sound insulation performance of the finished product. Additionally, this equipment is an ideal choice for producing high-quality products using a PVC window mold for interior decoration, meeting diverse architectural decoration needs.

Product details
Precise Forming of Multi-Cavity Irregular Structures: Optimized for the characteristics of a UPVC profile extrusion die for construction, the internal flow channel undergoes fluid dynamics optimization to support the one-pass extrusion of complex structures like seven-chamber designs. The unique geometric smooth transition design eliminates melt stagnation, ensuring uniform wall thickness and precise sealing slot dimensions, effectively guaranteeing the air tightness and water tightness of the window.
Corrosion-Resistant and Wear-Resistant Material & Surface Treatment: The mold body is made of high-quality 3Cr13 or 2Cr13 stainless steel (Hardness HRC≥24), treated with mirror polishing and nitriding. This highly corrosion-resistant surface effectively resists acid erosion generated during PVC processing, extending the service life of the UPVC waterproof frame extrusion die while preventing crystal points or scratches on the profile surface, ensuring appearance quality.
Dry/Wet Composite Calibration Mold with Efficient Cooling: The calibration section features multi-zone independent water cooling, floating cavities, and a high-sealing vacuum box. This efficient cooling and vacuum control system enables rapid setting and significantly reduces internal stress shrinkage, achieving a dimensional accuracy of ±0.03 mm. It perfectly adapts to high-speed extrusion lines (1–3 m/min), greatly improving production efficiency.
Co-extrusion Compatibility & Automation Adaptation: High-end PVC window molds for interior decoration support synchronous co-extrusion of the UPVC body with foam or colored layers (e.g., wood grain effects) with balanced flow pressure distribution. The modular design not only facilitates maintenance but also seamlessly integrates with automatic mold changing systems, online inspection equipment, and MES systems, meeting smart manufacturing requirements.
Integrated Waterproof Structure Forming Capability: Through precision die micro-structure design (such as rabbets and drip lines), the window frame profile comes with built-in drainage and diversion functions. This not only reduces reliance on sealants in later stages but also enhances the overall water tightness of the window (reaching GB/T 7106 ≥ Level 3), reflecting the superior functional design advantages of the UPVC waterproof frame extrusion die.
