PVC door and window profile making machine mainly composed by conical Twin Screw Extruder, Cooling Table, Hauling Machine, Cutting Machine, Stacker. With different moulds, it can produce various UPVC profile, such as: PVC window door profile, PVC wall panel, PVC window sill board, cabinet door board, curtain box, PVC trucking, cable duct, PVC skirting, PVC protection corner and so on.And by changing screw barrel and mould, it can also produce PVC based WPC products, such as: WPC wall panel, WPC window.
UPVC Door And Window Profile Extrusion Machine
PVC door and window profile making machine is essential in the manufacturing of PVC profiles. It's designed to extrude PVC resin into the desired shapes for doors and windows. The machine operates through a precise extrusion process, heating and shaping the material. It usually consists of a hopper, a screw - driven extruder, and a die. This equipment offers high - precision production, enabling the creation of durable, well - shaped PVC profiles that meet various architectural and construction requirements.
Product Advantages
1. High - precision production
The advanced extrusion technology enables the production of PVC profiles with accurate dimensions and consistent quality.
2. High - efficiency operation
PVC door and window profile - making machines can continuously extrude long - length PVC profiles at a stable rate.
3. Versatility
These machines can produce a wide variety of PVC door and window profiles with different shapes and sizes. By simply changing the extrusion die and some parameter settings.
4. Cost - effective
Through precise control of the extrusion process, the waste of PVC materials is minimized.
5. Good product quality
The extrusion process can evenly distribute the additives and modifiers in the PVC material, enhancing the strength, hardness and weather resistance of the profiles.
Technical Specifications
Extrusion Technology
The core application technology of a PVC door and window profile - making machine is extrusion. It involves heating the PVC resin pellets to a molten state. The machine uses a powerful screw - driven system to push the molten PVC through a die. The die is designed with the specific cross - sectional shape of the door or window profile. For example, for a casement window profile, the die will have a shape that includes the frame, sash, and any necessary grooves for glazing and hardware installation.
Vacuum Calibration Technology
After extrusion, vacuum calibration is used to cool and shape the profile precisely. The extruded profile enters a vacuum calibration chamber. The vacuum helps to draw the profile against the calibration tools, which have the exact dimensions of the desired final product. This process removes any irregularities and ensures that the profile has a smooth surface and accurate dimensions.
By creating a vacuum environment, air bubbles in the molten PVC are also removed, improving the quality of the profile. The cooling water in the calibration system rapidly cools the profile, solidifying the PVC and maintaining its shape as it exits the chamber.
Cutting Technology
Automated cutting technology is an important part of the machine's operation. Once the profile has been extruded and calibrated, it needs to be cut to the appropriate lengths. The cutting mechanism can be programmed to cut the profiles at specific lengths according to the requirements of the door and window manufacturing process.
Some advanced machines use high - speed saw blades or laser - cutting technology. Laser - cutting can provide a more precise cut with a smooth edge, reducing the need for further finishing of the cut ends. The cutting process is synchronized with the extrusion speed to ensure continuous and efficient production.
Application
Residential Building Applications
PVC door and window profile - making machines are widely used in the production of profiles for residential buildings. They can produce a variety of profiles for different types of doors and windows such as casement windows, sliding doors, and French doors. These profiles are used to create frames that are lightweight, durable, and have good insulation properties. For example, the profiles for energy - efficient windows can help to reduce heat transfer between the inside and outside of a house, thus saving energy costs for heating and cooling.
Commercial Building Applications
In commercial buildings like offices, shopping malls, and hotels, these machines are used to make large - scale door and window profiles. The profiles produced can be used to fabricate large glass doors and windows that provide good natural light penetration and an aesthetically pleasing appearance. The machine - made PVC profiles can also meet the requirements of fire - resistance and sound - insulation standards in commercial settings. For instance, in a noisy urban area, sound - insulated PVC window profiles can reduce the noise from the street, creating a more comfortable indoor environment.
Industrial Building Applications
For industrial buildings such as factories and warehouses, the PVC door and window profile - making machine is used to produce robust and durable profiles. These profiles are designed to withstand harsher conditions such as exposure to chemicals, heavy impacts, and extreme temperatures. The machine can produce profiles with thicker walls and stronger structures for industrial - grade doors and windows that need to provide security and protection while still allowing for proper ventilation and light access.
