1、 What are the processes of plastic processing
1. Thinning the product. Is foam molding done by adding foam materials such as PVC, PE, and PS? Is it appropriate to use foaming agents to produce plastic? The process of microporous structure.? Almost all thermosets and thermoplastics can be made into foam plastics, and foam molding has become a plastic processing technology? In the middle? An important field.

2. It is a process of using plastic sol or organic sol to coat the surface of substrates such as cloth or paper, making imitation leather products, lacquer cloth or plastic wallpaper, or coating powdered plastic on metal surfaces. Common plastic coated products include synthetic leather, lacquer cloth, plastic wallpaper, and various metal coated products. Casting molding is a method of plastic processing.

3. Vacuum forming, commonly known as vacuum forming, is a plastic processing technique that involves heating a flat plastic sheet to soften it, then vacuum adsorbing it onto the surface of a mold, and cooling it before forming. It is widely used in industries such as plastic packaging, lighting, advertising, and decoration.

4. The main precautions and processes involved in plastic injection molding include the molding cycle of injection molded products, which includes injection molding time and product cooling time. Effective control of these times has a profound impact on the quality of the product. We should clarify the product molding cycle through sample design and other methods before injection molding production.

5. The emergence of plastic packaging bottles has facilitated people's production and life, and has been widely used in various industries. The processing techniques for bottles mainly include extrusion blowing and injection pull blowing, and the types of bottles produced by these two processes also differ.

2、 What are the procedures for making plastic molds
1. If there are ready-made mold templates, all that is needed is to process the cavity and core, and assemble the holes with pliers. If everything starts from scratch, it is necessary to start cutting, milling, planing, grinding, shaping the template, and then start processing the cavity, core, etc.

2. The process of making plastic molds is as follows: during injection molding, the mold is clamped on the injection molding machine, molten plastic is injected into the molding cavity, and cooled and shaped in the cavity. Separate the upper and lower molds, and use the ejection system to eject the product from the mold cavity and leave the mold. The mold is closed again for the next injection molding, and the entire injection molding process is cyclical.

3. Polishing the surface of the flow channel to increase surface smoothness; Before assembly, check and clean to prevent rust; 1. Injection mold assembly; 1. Test the mold, debug it without any problems, and complete it with just one set of molds. Generally speaking, the production time of injection molds is related to the size and complexity of the product, with a typical cycle of 15-20 days. For mobile phone molds, the fastest trial period is 7 days.

4. Precision machining - electrical discharge machining: using the principle of electrical discharge erosion to process fine parts of molds- Numerical control milling: using a numerical control milling machine for high-precision cutting processing. Grinding: Use a grinder to grind the surface of the mold to the required precision and smoothness.

5. According to the results of the trial mold, necessary adjustments and adjustments are made to the mold to ensure that it meets production requirements.

Surface treatments such as coating, painting, etc. are used to improve the corrosion resistance and surface texture of the mold. Conclusion: The production of plastic molds is a complex and intricate process that involves multiple technologies and techniques.

6. It is best to indicate the part number, name, material, material shrinkage rate, drawing scale, etc. below the process diagram. Usually, the process is illustrated on the mold assembly drawing. The final assembly drawing of the mold should include the following content: the structural form of the mold forming part, the pouring system, and the exhaust system.
