Fabrication Excellence & Quality Assurance
At Wintech UPVC Solutions, engineering precision is at the heart of every window and door system. We utilize automated double-head cutting saws, precision routing, and high-temperature fusion welding to guarantee structural integrity, weather-tight sealing, and millimeter-accurate tolerances.
6-Stage Precision Manufacturing Process
Precision Cutting
uPVC profiles and steel reinforcements are cut to exact millimeter dimensions using automated double-head cutting saws.
Steel Insertion
Galvanized steel is inserted and securely fastened inside the profiles for structural integrity.
Routing & Drilling
Automated CNC machines route water drainage slots and drill precise holes for handles and locking mechanisms.
Fusion Welding
Profile corners are melted and fused together at 250°C, creating a seamless, immensely strong joint.
Corner Cleaning
Automated corner cleaners remove excess weld sprues, leaving a flawless, aesthetic finish.
Hardware Assembly & Glazing
Premium hardware is attached, EPDM gaskets are installed, and the chosen glass is carefully fitted and beaded.
Quality Control Tests
Dimensional accuracy, corner weld strength testing, water tightness inspection, and manual hardware checks.
Technical Profile Composition
Internal cross-section engineering that separates Wintech from ordinary fabricators.
Multi-Chambered uPVC Profile
The core of our windows features 3, 4, or 5 distinct internal chambers. These chambers provide structural rigidity and trap dead air for thermal and acoustic insulation.
Galvanized Steel Reinforcement
Every main profile is internally reinforced with G.I. (Galvanized Iron) steel liners ranging from 1.2mm to 2.0mm in thickness, depending on wind load requirements. This prevents bending and allows for large-scale window designs.
EPDM Weather Gaskets
High-grade EPDM rubber gaskets provide an airtight and watertight seal, preventing dust, water, and drafts from entering the premises.
Fusion Welded Joints
Unlike aluminum windows which are mechanically joined with screws, Wintech uPVC corners are fusion-welded at extremely high temperatures (250°C). This creates a solid, single-piece frame that is structurally superior and completely leak-proof.
Glazing Bead
A co-extruded glazing bead securely holds the glass in place while allowing for easy glass replacement if ever required.
4 Rigorous Factory Quality Control Tests
Dimensional Accuracy
Ensuring the frame perfectly matches the site survey measurements.
Weld Strength Test
Corners are pressure-tested to ensure they will not break under structural stress.
Water Tightness
Drain slots and gaskets are checked to guarantee zero water leakage.
Hardware Operation
Every handle, lock, and roller is operated manually to ensure smooth functionality.
