They are used in a variety of products, from window frames to tubing, plastic profiles are popular due to being lightweight, durable and easily shaped. However, it may be difficult to obtain these profiles from manufacturing, where warping, surface defects, shrinkage, brittleness and lack of color uniformity are some of the potential problems. Lianzhen and others can produce good quality Plastic Profile by knowing these trouble and the methods to solve them
The demand for small, lightweight profiles for doors and windows in high- quality PVC systems is as great as ever
A quick guide to cooling of PVC profiles Development in modern machinery technology and production systems have made it possible to produce high quality products with improved quality while at the same time reducing costs at various stages of production. Understanding what the cause(s) is also means that this problem can be solved
If the plastic profiles are not properly cooled, they can warp
Warpage occurs due to uneven cooling of the plastic. To avoid this, it is crucial that the cooling process be regulated with great care. On the Lianzhen side, we ensure even, slow cooling, allowing the profiles to retain their shape. We also have specific devices to cool the profiles on all surfaces so they are perfect
Through the use of appropriate tooling and process settings, the surface quality of plastic profiles can be enhanced to minimize roughness and imperfections
Plastic profiles may occasionally be produced with a rough surface or imperfections. This can be corrected by applying the appropriate tools and methods. More from Lianzhen we regularly test our tools to see if they are sharp and well maintained. We’ll change my machines so that the Plastic comes out smooth, looks good. That way, our profiles not just perform well, but also look good
By addressing shrinkage causes such as insufficient temperature control and inappropriate mold design, will prevent plastic profiles from keeping to the proper dimensions
Shrinkage is when the plastic profiles are smaller than they should be when they are cooled. Shrinkage can be successfully dealt with by the careful control of the temperature and using molds designed to accommodate it. At Lianzhen, we carefully monitor the temperature as we produce our materials and use molds of high quality produced in this way to deliver profiles exactly as they should be. Choosing the right material and ensuring optimized extrusion parameters may also help to avoid the profiles becoming brittle and cracking when they are under acute stress. If the production process uses poor material quality or preparation, the profile produced runs the risk of becoming brittle and breaking
At Lianzhen, we only use top-quality materials and top-of-the-line extrusion mechanisms. We ensure that the Plastic is heated to the optimal temperature required and pushed through the flow at the correct velocity. This ensures that our plastic profiles are durable and resistant to breaking from outside pressure. It is also essential to ensure that the pigment used is spread evenly and consistently mixed
