400mm Double Head precision Cutting Saw PVC Window Profile Processing Equipment
The 400mm Double Head Cutting Saw is a professional profile cutting machine engineered for PVC, UPVC, and vinyl window and door production. Equipped with two synchronized carbide-tipped saw blades (Ø400mm), it performs simultaneous two-end cutting at 45° and 90°, delivering burr-free, melt-free ends with repeat accuracy up to ±0.3mm. The machine features pneumatic auto-feed with adjustable damping, horizontal and vertical pneumatic clamping, and a movable head with digital length positioning (450–3500mm range). Designed for batch processing, it cuts window frames, sashes, mullions, and transoms in a single pass, significantly improving production efficiency. Built with a welded steel frame and precision linear guides, it offers low-vibration, long-service operation. CE certification and voltage customization (220V/380V/415V) are available for global markets.
The 400mm Double Head Cutting Saw is a dedicated profile cutting machine for PVC, UPVC, Vinyl and plastic window and door manufacturing. Equipped with two synchronized carbide-tipped saw heads (Ø400 mm), it performs simultaneous two-end cutting at 45° and 90°, delivering square, burr-free, melt-free ends ready for welding or assembly.
Designed around a pneumatic feed + pneumatic clamping system with adjustable damping cylinders, the machine combines clean cutting, stable operation and high repeatability — ideal for batch production of window frames, sashes, mullions and transoms.
Profile height capacity spans from 20 to 110 mm, covering most standard window and door extrusions. The drivetrain combines a 2.2 kW motor with a gearbox and bearing set chosen for steady, low-failure-rate operation during continuous shifts. In a typical eight-hour shift, the machine handles enough cutting for roughly 25 to 35 standard window frames, depending on profile geometry. Power supply can be configured to match the local voltage and frequency at the time of order, and the standard build accepts both 380V and 220V three-phase inputs.
Each machine undergoes a factory-run test before shipment, with a machinery test report and an outgoing-inspection video provided as documentation. The welded frame measures 4000 × 900 × 1500 mm and weighs approximately 600 kg. Lebulang Machine, which has manufactured window and door processing equipment at its China factory for close to 30 years, produces this saw. The unit holds CE and ISO certification, and custom OEM specifications are accepted. Supply is on a factory-direct basis, the design is laid out for straightforward daily upkeep, and remote installation guidance is included at no extra charge.

Key Features
Dual Saw Heads, One Pass — Both heads cut simultaneously, reducing cycle time by up to 50% vs. single-head saws; perfect squareness on both profile ends
Optimized for PVC / UPVC — Cutter speed and blade tooth count (Z≈144 for PVC) tuned for thermoplastics: smooth edges, no melting, no tearing
Standard 45° / 90° + Adjustable Angles — Rotary worktable indexes between -45°, 90°, +45°; intermediate angles set manually with quick-pin stops
Pneumatic Auto Feed with Damping — Air-driven saw advance with adjustable speed; smooth, chatter-free cutting, longer blade life
Horizontal + Vertical Pneumatic Clamps — 4 clamping cylinders lock the profile firmly, preventing thin-wall deformation or shifting
High Repeat Accuracy — Repeat positioning ≤ 0.3 mm; angle tolerance ±5′; cut surface flatness ≤ 0.10 mm
Digital Display Optional — Digital length ruler for fast, precise movable head positioning
Movable Safety Shields — Self-closing saw covers on both heads for operator protection
Also Cuts Light Aluminum — Suitable for thin aluminum and composite profiles (coolant spray optional)
FAQ
Q1: What types of profiles can this four-head welding machine process?
A: It is fully applicable to ordinary UPVC/PVC profiles, co-extruded colored profiles, and film-coated profiles. It can effectively avoid film tearing and foaming, ensuring flawless and seamless welding for high-end colored window frames.
Q2: What welding angles can the machine achieve?
A: This machine supports multi-angle welding ranging from 30° to 180°. The machine heads can work separately or in combination, realizing standard 90° right-angle welding and special irregular angle welding for customized window and door frames.
Q3: Is the weld seam adjustable? What is the adjustment range?
A: Yes. Equipped with profile clamps with cutters, the welding seam is precisely adjustable from 0.2mm to 2mm, meeting both standard and colored profile processing requirements, with clean and flat welding corners.
Q4: Do you support customization and OEM service?
A: Yes. We support OEM/ODM, custom machine color, special fixtures, film-coating anti-tearing functions and special size parameters to match customers' unique profile production needs.
