Common materials for filters are: polyethylene (PE), polypropylene (PP), and polyamide (PA). Advantages: Corrosion resistance, low weight, increased filtration area, improved filtration efficiency

Plastic and metal integration are also called injection molding processing and plastic injection molding processing. Common raw materials: hardware parts are normally attributed to metal composite materials, stainless steel plates, red copper, aluminum alloy profiles, battery charging terminals,cables, steel wires, metal milling parts and other metal parts; some common raw materials for plastics are PC, ABS, PP, POM, TPE, TPU, PVC, PA66, PA6, PA46, hard glue, soft Adhesives, are widely used in all walks of life.

Plastic trestle is mainly manufactured by the injection molding process. The principle is to add granular or powdery raw materials into the hopper of the injection machine, and the raw materials are heated and melted into a flowing state. The gating system enters the mold cavity, and hardens and shapes in the mold cavity. Factors affecting the quality of injection molding: injection pressure, injection time, injection temperature. Plastic molding is divided into horizontal injection molding, vertical injection molding, two-color injection molding, low pressure injection molding, etc.

There are three types of printers: dot matrix printers, inkjet printers, and laser printers. In line with the lightweight trend of printers, the outer shell of the printer is generally made of thermoplastics, and the general-purpose plastics used for ordinary printer shells are generally used in large quantities, with wide uses, good formability, and cheap plastics.
