China automatic 45 degree miter 90 degree square cut saw Manufacturer, Supplier, Factory

This dual-head seamless welding machine is a core fabrication unit for high-end uPVC, PVC, and vinyl window and door production. Two synchronized welding heads (left fixed, right movable with pneumatic brake) complete 90° and V-shaped corner joints in one cycle, delivering a 0.2 mm invisible seam without upper/lower welding beads—eliminating most manual corner cleaning for both white and color-foil / co-extruded profiles.

PVC Water Slot Milling Machine for Windows is a multifunctional double-head copy routing and drilling machine specially designed for aluminum and PVC door and window profile processing. It integrates water slot milling, key lock hole routing and special groove drilling functions in one equipment. Supporting dual copying modes of template simulation and auxiliary positioning, the machine realizes high-precision one-time forming of various profile holes and grooves. With foot-switch pneumatic pressing control, compact body structure and adjustable templates, it ensures safe operation, strong compatibility and stable processing quality, serving as essential auxiliary equipment for standardized UPVC and aluminum window production lines.

Engineered for high-throughput architectural aluminum fabrication, this 4-meter CNC machining center is built to handle long-span profiles with uncompromising precision. Unlike standard short-bed machines, it processes full-length window, door, and curtain wall profiles in a single cycle—eliminating mid-profile repositioning and ensuring perfect linear accuracy. Equipped with a high-speed electrospindle, automatic tool changer (ATC), and servo-driven clamping system, it seamlessly executes drilling, tapping, milling, and slotting operations with ±0.1mm accuracy. Designed for manufacturers who demand both volume and versatility, it drastically reduces labor costs, minimizes material handling, and guarantees consistent quality across every meter of the profile

The Arbitrary Angle Welding Machine for PVC / UPVC Windows​ is a specialized single-head corner welding solution designed for non-90° and arch window fabrication. It supports continuous angle adjustment from 30° to 180°, enabling precise welding of special-shaped vinyl window and door frames. Equipped with a PLC control system, pneumatic clamping, and an intuitive touch screen interface, it delivers ±0.2mm welding accuracy with stable, repeatable results. Ideal for UPVC manufacturers producing curved, angled, or custom-profile frames beyond standard right-angle joints.

The 450mm CNC Double Head Internal Swing Precision Cutting Saw (45°/90°) is a high-end profile cutting machine designed for aluminum, thermal-break aluminum, and UPVC/PVC window and door production. Equipped with two synchronized Ø450mm TCT carbide blades and CNC-controlled inward-swing saw heads, it performs simultaneous two-end mitre cutting at 45° and 90° with repeat accuracy up to ±0.1mm. The machine features pneumatic auto-feed with adjustable damping, horizontal and vertical pneumatic clamping, and CNC digital positioning for cutting lengths up to 3700mm. The internal swing head design saves floor space while ensuring stable, vibration-free operation. Built for batch production, it delivers burr-free, square ends ready for assembly. CE certification and voltage customization (220V/380V/415V) available for global markets.

A 1600mm horizontal heated roller press​ designed for the final sealing and curing of flexible spacer (Super Spacer / rubber strip) insulating glass units. After spacer application, glass passes through quartz heating zones (0–300°C) to soften the spacer, then through synchronized upper and lower rubber rollers that apply uniform pressure for a permanent, airtight bond — no bubbles, no gaps, no rework.
