Injection molding technology plays a very important role in modern industrial production. It can not only improve production efficiency and product quality, but also reduce production costs, bringing more development opportunities for enterprises. With the continuous development and progress of technology, injection molding technology will be increasingly valued and become the preferred processing technology for more enterprises.
The advantages of injection molding mainly include high production efficiency, stable operation of injection molding equipment, continuous production, and improved production efficiency. Secondly, the product quality is stable. Injection molded products have smooth surfaces, precise dimensions, and stable and reliable quality. Furthermore, the process is flexible and diverse, allowing for the production of various shapes, sizes, and colors of products to meet market demands.
What are the choices of injection molding materials in Dalian?
Polypropylene (PP): Polypropylene has good wear resistance and chemical corrosion resistance, and is a commonly used injection molding material, suitable for making various containers, pipes, furniture and other products.
Polyethylene (PE): Polyethylene is an injection molding material with good heat and low temperature resistance, commonly used to make disposable tableware, packaging bags, toys and other products.
Polystyrene (PS): Polystyrene has high transparency and a flat surface, making it suitable for making transparent packaging boxes, toys, electrical casings, and other products.
Polyacrylamide (PA): Polyacrylamide is an injection molding material with good heat resistance and wear resistance, commonly used in the production of mechanical parts, automotive parts, and other products.
Polycarbonate (PC): Polycarbonate has good transparency and impact resistance, and is suitable for making products such as eyeglass lenses and electronic product casings.
Polystyrene Nitrile Rubber (ABS): ABS has good strength and impact resistance, and is suitable for making products such as telephone cases and electrical enclosures.
Polyvinyl chloride (PVC): PVC is an inexpensive injection molding material commonly used in the production of products such as water pipes and wire sleeves.
Injection molding technology has a high degree of automation and production efficiency. Due to the high degree of automation of injection molding equipment, production efficiency can be greatly improved. Compared to manual operations or other manual processing methods, injection molding technology can complete the manufacturing process of products faster and more accurately, greatly shortening the production cycle.
The process of injection molding generally includes the following steps: raw material pre-treatment, melt injection, mold sealing, cooling and solidification, mold opening, and demolding. Firstly, the plastic particles are subjected to pre-treatment processes such as drying and mixing, and then sent into the injection machine for melting. After the plastic is completely melted, it is injected into the mold under high pressure. After cooling, the plastic solidifies into shape, and then opened by the mold to remove the finished product.
