How about Changchun Zhongtuo Molding Technology Co., Ltd.

Changchun zhongtuo molding technology co., ltd was established in November 29 and is a wholly-owned subsidiary of Beijing zhongtuo machinery co., ltd. With a registered capital of 15 million yuan, it is located in Erdao Industrial Cluster in Changchun, with an existing factory building of 1, square meters. There are 32 Haitian energy-saving MA series injection molding machines and one low-pressure micro-foaming injection molding machine. Is a high-tech enterprise integrating scientific research, development, production and sales. It is a qualified designated supplier of plastic products for FAW-Volkswagen and FAW Car. Relying on new technology, expanding the company's new business in the field of plastic products is an important part of China Extension's development plan. At present, in the aspect of new plastic technology and new products, the research achievements with independent intellectual property rights (many patents have been applied) are as follows:

1. Weld-free injection technology and equipment In the injection process, a special mold heating and cooling control system is adopted, and the mold is quickly heated to a certain temperature before injection, and the sol does not cool down during the flow, but quickly cools down after injection to shorten the molding cycle. This technology is mainly used in the production of plastic parts (such as TV front frame, etc.), high transparency plastic parts (such as car lampshade, etc.) and automobile central control panel without spraying. Can improve product quality and reduce production cost.

2. microcellular foaming low-pressure injection molding and extrusion technology and equipment. A certain proportion of inert gas (N2 or CO2) is dissolved in the sol, and the gas is precipitated to form tiny pores during cooling. The outstanding advantages of this technology are: reducing the viscosity of sol, reducing injection pressure, improving the dimensional stability of products, saving materials and so on. At present, the developed equipment and technology have been successfully applied to the industrial production of plastic sheet extrusion, and injection molding has also been successfully tested.

3. The sudden emergence of IMD technology in recent years will surely bring about a revolution in automobile interior decoration. The embedded in-mold labeling technology independently developed by our company will soon form industrial scale production.
