With the continuous development of the plastics industry, the multi-functional composite structure and green environmental protection of plastic products will become the development direction of the plastics industry. Various new injection molding machines and injection molding processes are emerging, and backward and inefficient production technologies are bound to follow the injection molding technology. With progress and elimination, production companies can only adapt to the development of the market by continuously updating or improving production equipment and technology. Hybrid color mixing plastic product production technology is actually a kind of co-injection molding technology. The co-injection molding technology is an injection molding machine with multiple injection systems, which simultaneously or sequentially injects plastics of different colors or different materials or different colors and materials. method. There are two methods for forming two-color plastic products: One is to use two sets of independent ordinary injection molding machines, one injection molding machine injection molding a color plastic insert, and then placing the insert on another injection molding machine, and then injecting another color of plastic, Finally, a two-color plastic product is obtained. This method is a relatively traditional molding method. The equipment used is simple and the method is easy, but it requires high labor cost, and under the production efficiency, the production technology is backward, and the large-scale enterprises have already eliminated the production method. The second method is to directly use a two-color injection molding machine. Two colors or materials of plastic are injection molded on the same injection molding machine. The two-color injection molding machine uses two independent injection molding machines to plasticize different colors and types of plastics through different barrels. The intermediate process does not require manual participation, enabling automatic production of two-color plastic products. However, the use of this method to produce two-color plastic products, the initial equipment investment costs are high, equipment maintenance management requirements are high, it is difficult for small and medium-sized enterprises to introduce the production equipment on a large scale. Polypropylene is a kind of thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general plastic. It has chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear-resisting processing properties. It is widely used in the production of fiber products such as clothing, blankets, medical devices, automobiles, bicycles, parts, transportation pipes, chemical containers, etc., as well as food and drug packaging Pp Resin,Polypropylene Resin,Polypropylene Resin Pellets,Polypropylene Resin Plastic Jiangsu Zijun International Trade Co., Ltd. , https://www.zijunplastic.com
