1. Thin the product. Foam molding is added to foam materials (PVC, PE and PS, etc.). Proper blowing agent to make plastic production? The process of microporous structure.? Almost all thermosets and thermoplastics can be made into foams. Middle? important areas.
2. It is a process that uses plastisol or organosol to coat the surface of cloth or paper and other substrates to make imitation leather products, lacquered cloth or plastic wallpaper, etc., or coat powdered plastic on the metal surface. Common plastic coated products include artificial leather, lacquered cloth, plastic wallpaper and various metal coated products. 1 Pouring molding is a method of plastic processing.
3. Vacuum forming, often known as blistering, is a plastic processing technology, the main principle is to heat the flat plastic hard sheet to soften, use vacuum adsorption on the surface of the mold, cooling and molding, widely used in plastic packaging, lighting, advertising, decoration and other industries.
4. The main precautions for plastic injection molding processing and the processes included therein: The molding cycle of injection molding products, which includes injection molding time and product cooling time, has a profound impact on the quality of the product. Before the injection molding production, we should clarify the product molding cycle through the sample pattern and other methods.
5. The emergence of plastic packaging bottles has facilitated people's production and life, and has been widely used in all walks of life. There are two main types of bottle processing technology: extrusion blowing and injection pull blowing, and the types of bottles produced by these two processes are also different.
1. If there is a ready-made mold template, only the process cavity and core need to be processed, and the fitter can do the hole assembly. If everything is done from scratch, it is necessary to start cutting, milling, planing, grinding, the shape of the template, and then start processing the cavity, core, etc.
2. The process of plastic mold production is as follows: during injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the molding mold cavity, and cooled and shaped in the cavity. The upper and lower molds are separated, and the products are ejected from the mold cavity and out of the mold through the ejection system. The mold is then closed for the next injection molding, and the entire injection molding process is cyclical.
3. The surface of the runner is polished to increase the surface finish; 1. Check before assembly, and do a good job of cleaning and rust prevention; 1. Injection mold assembly; 1. Mold test, no problem in debugging, a pair of molds is completed. Generally speaking, the production time of injection molds is related to the size and complexity of the product, usually the cycle is 15-20 days, and the fastest 7 days for mobile phone molds.
4. Finishing - EDM: Using the principle of EDM erosion, the fine parts of the mold are processed. - CNC milling: High-precision cutting with a CNC milling machine. Grinding uses a grinder to grind the surface of the mold to the desired precision and finish.
5. Mold adjustment and trimming According to the results of the mold test, make necessary adjustments and trimming to the mold to ensure that it meets the production needs.
Surface treatment such as coating, painting, etc., to improve the corrosion resistance and surface texture of the mold. Conclusion Plastic mold making is a complex and delicate process, involving a variety of technologies and processes.
6. It is best to mark the part number, name, material, material shrinkage, drawing ratio, etc. under the process diagram.
Usually the process drawing is drawn on the mold ** diagram. The mold diagram should include the following: The structure of the mold forming part The structure of the gating system and the exhaust system.
