LVT (Luxury Vinyl Tile) is another name for PVC sheet flooring. In 2013, Gwell successfully developed LVT floor extrusion lamination production line, and realized one-time lamination of WPC floor laminating materials, which improved production line efficiency and quality stability. It has been exported to some countries in Europe and America. Because its design and color are rich, it is popular to be used at home outfit and commercial domain. LVT extrusion production process: floor materials such as PVC plasticizer, calcium powder, mixed by high speed mixer mixing and delivered by rotating conveyor to the conical twin-screw extruder, then extuded by T die and attach the wear-resisting layer and printing layer to the product with specified thickness. Extrusion laminating process can replace the traditional rolling, laminated and complex process. It is easy to operate, has low investment cost, and can reduce the labor intensity of workers. Also it can keep workshop clean, and the production line will adopt optical sensor detection and alarm, so it has a high degree of automation.

A machine screw is a screw with a slotted head or socket heads often used for fastening metal parts securely together in various types of machinery or construction. Machine screws are unique, though, because of their size. These are used in threaded holes and are likely to end up with a stronger joint.
