Workshop process designed annual output of 10,000 tons of door and window profile
Abstract: Plastic doors and windows has excellent performance that traditional doors and windows difficult to compare. It is so energy-saving and environment-friendly as to becoming the product that ministry of our construction promotes it’s use. For the present, plastic doors and windows has been widely used in all kinds of architectural engineering, it has a bright future.U - PVC plastic as an emerging energy-saving materials in the current applications have played more and more important role in building energy efficiency and improve, living environment plays a significant role.This design, starting from PVC production technology choice commonly used twin-screw extrusion molding method production PVC plastic doors and Windows, through the formula selection, material calculation, equipment selection, process parameters are controlled for the whole process flow process such as more detailed elaboration.
Key Words: plastic windows and doors；PVC-U；production workshop；process design
