Through "type segmentation + parameter customization", our extruders achieve accurate adaptation of "cost reduction for small capacity, efficiency improvement for large capacity, and quality guarantee for complex profiles". Whether for small and medium-batch production (BLX-150 series) or large-scale mass production (BLX-850), the optimal screw configuration can be matched to help customers balance the three core demands of "production capacity, energy consumption, and product qualification rate", and reduce comprehensive production costs.
2. Die of PVC Window Profile Extrusion Lines
High precision of molds is a difficulty in window profile molding, but it is our core advantage. With "unique precision processing technology + accurate customization" as the core, Blesson helps customers enhance product competitiveness:
- 1. Extrusion die head options: FS136 high-grade mold steel (hardness up to HRC50-52) or 2Cr13 stainless steel;
- 2. Universal calibration die: The main body of the calibration die is uniformly made of 2Cr13 stainless steel, supporting multi-section combination of 200~300mm/section for flexible adaptation to production needs;
- 3. Core Advantages: The service life of FS136 material molds is increased by more than 40% compared with conventional materials, reducing mold change downtime and replacement costs, and helping customers lower comprehensive costs; 2Cr13 stainless steel calibration dies are rust-resistant and durable, suitable for various PVC-U raw material characteristics;
- 4. Precision Processing Technology (standard for all PVC Window Profile Production Lines): All supporting molds for PVC Window Profile Extrusion Lines adopt 5-axis machining centers for integrated cavity forming, combined with ultra-precision polishing technology (surface roughness Ra≤0.4μm), ensuring scratch-free and flawless surfaces of produced PVC/UPVC window profiles; the molds adopt "stepwise temperature control + stress relief" heat treatment process as a whole, with multi-zone temperature control accuracy of ±1℃ and deformation controlled within 0.02mm/m, which can avoid mold deviation and dimensional drift of UPVC Windows Profile Making Machines during long-term operation, and ensure consistent quality of mass-produced PVC/UPVC window profiles.
The core competitiveness of Blesson molds lies in "model-specific matching":
- 1:1 Accurate Development: Exclusive molds can be customized for each model of PVC Window Profile Extrusion Line according to physical samples, CAD drawings or 3D models provided by customers, supporting the development of various window profiles such as casement windows, sliding windows, system windows, as well as special structures with drainage grooves and reinforcing ribs.

The cutting action can be seamlessly linked with the traction system, which not only ensures production continuity but also reduces material waste. It is one of the iconic advantages of the efficient operation of UPVC Window Profile Extrusion Machine.
6. Control System of PVC Window Profile Extrusion Line
The control system of Window Profile Extrusion Line is compatible with PVC Profile Extrusion Line and UPVC Window Profile Extrusion Line, and can realize precise coordination of all processes such as extrusion, traction and cutting. The system supports storing multiple sets of production formulas, and can quickly call the corresponding parameters when switching products, greatly reducing debugging time and significantly improving production efficiency. This function plays a key supporting role in optimizing the daily production processes of PVC profile extrusion machine and UPVC Windows Profile Making Machine.
5 Advantages of PVC Window Profile Compared with Aluminum and Wooden Doors and Windows
- 1. The cost of windows is highly controllable:
Under the same strength, the cost of PVC raw materials is much lower than that of aluminum (the advantage is more obvious after metal price increases), ensuring better profit margins.
- 2. The product application range of PVC window profiles is extensive.:
Relying on color film/co-extrusion technology, it can realize multi-style adaptation, which not only avoids the problem of frequent maintenance of wooden windows but also solves the shortcoming of high price of colored aluminum windows.
- 3. The window's durability is prominent:
PVC Window Profile contains embedded steel, multi-cavity drainage structure and anti-ultraviolet components, with long service life and low after-sales cost.
- 4. Excellent Thermal Insulation:
The thermal conductivity is much lower than that of aluminum profiles. Combined with the multi-cavity design, it has a prominent heat insulation effect. For the same type of room using PVC Window Profile, the room temperature is 5-7℃ lower than that with aluminum windows in summer and 8-15℃ higher in winter.
- 5. Strong Sound Insulation:
Adopting welded assembly + closed multi-cavity structure, combined with insulating glass with good sealing effect, it has a significant sound insulation effect, especially suitable for the sound insulation needs of urban center residences.
