The field and production process characteristics of two-color injection molding in Suzhou
Suzhou Two-color Injection Molding Factory: Application of Suzhou Two-color Injection Molding Technology in Subdivision Fields: Two-color Injection Molding Technology, as its name implies, is also called Two-material Injection Molding Technology. This is a technology that uses two plastic materials to mix and inject plastic products. Its technical connotation is actually to use a mold component to shape the shape and "weld" a continuous molding work in the mold ", therefore, the fundamental principle is to plasticize two different plastic raw materials, and then use the mold for welding and installation, so as to achieve the purpose of two-color injection molding and meet the needs of different customers.

As the name implies, two-color injection molding is also called two-material injection molding technology. This is a technology that uses two plastic materials to mix and inject plastic products. Its technical connotation is actually to use a mold component to shape the shape and "weld" a continuous molding work in the mold. Therefore, the fundamental principle is to plasticize two different plastic raw materials and then use the mold for welding and installation, in order to achieve the purpose of two-color injection molding, to meet the needs of different customers.
1. At present, three-proof mobile phones, three-proof tablets, medical treatment, children's smart watches, electric toothbrushes, law enforcement instruments, TWS Bluetooth wireless headphones, military handheld and other sub-industries have been applied to this process. Compared with ordinary injection molding, Suzhou two-color injection molding technology has higher requirements for mold making and injection molding machines. After years of development, Suzhou two-color injection molding technology has been applied in more and more markets. It is a technology with great development potential, there are few things the industry can do well.
2. When we make hand-board models, we often encounter the needs of customers for two-color projects. Two-color injection molding technology has given us a lot of reference and reference. How to optimize the production of hand-board models through two-color technology is very practical to meet customer needs.
3. The hand-plate model can make use of the good simulation, strength and extremely low shrinkage of silica gel by making the original mold first, then opening the silicone mold, and then forming the two-color hand-plate (plastic-coated) mold for the second time. After repeated use, it can maintain prototype production and small batch production. Under the condition that the product does not have mass mold opening, it can provide plasticity and quickly put into the market, for parts with complex structure, fine pattern, no demoulding slope or reverse demoulding slope and deep grooves, they can be taken out directly after casting, which is unique compared to other molds.
4. The cross-border thinking brought to me by the two-color injection molding technology can be extended to other fields through this technology, which is a good inspiration for CMF micro-innovation. Some special deep texture processes cannot be realized through lithography molds, which can be used for reference.
Suzhou double color injection molding factory: Suzhou double color injection molding products production process characteristics
1. The two-color injection molding machine is composed of two sets of plasticizing injection molding devices with exactly the same structure and specifications. The nozzle has a special structure according to the production mode, or is equipped with two sets of molds with exactly the same structure that can rotate and transpose. When plasticizing injection molding, it is required that the melt temperature, injection pressure, injection melt amount and other process parameters in the two sets of plasticizing injection molding devices are the same, and the fluctuation difference of process parameters in the two sets of devices should be minimized.
2. Two-color injection molding plastic products and ordinary injection molding plastic products, the melt temperature and injection pressure during injection molding should use higher parameter values, the main reason is that the two-color injection molding mold runner is relatively long, the structure is more complex, injection melt flow resistance is larger.
3. Two-color injection molding plastic products should use raw materials with good thermal stability and low melt viscosity to avoid decomposition due to high melt temperature and long residence time in the runner. The most widely used plastics are polyolefin resins, polystyrene and ABS materials.
4. Two-color plastic products in injection molding, in order to make the two different colors of the melt in the mold can be well welded, to ensure the quality of injection molding products, should be used higher melt temperature, higher mold temperature, higher injection pressure and injection rate.

On May 20, 2023, Xinyu launched an outdoor expansion activity with the theme of "Cohesion to Win the Future" in Anji Zhuhai. Through the development of the activity, the cohesion and overall centripetal force of the employee group were enhanced, and the positive communication between employees was established., Mutual trust, unity and cooperation, cultivate team awareness, and increase the sense of responsibility of employees. One by one well-designed team building games aroused everyone's strong interest and enthusiasm. In the process of cross-game experience, the team members won one by one with the cooperation. This activity not only enhanced the cohesion between Xinyu employees, but also cultivated a tacit understanding between each other.
2023/9/21, the launching ceremony of the digital supply chain platform of Wujiang Xinyu Precision Mould Co., Ltd. was solemnly held in Suzhou Taihu International Conference Center. Gan Xiangquan, general manager of the company, spoke on behalf of Xinyu Company. Since then, the company has officially taken a big step towards a new model, a new journey and a new future!
Plastic mold design and manufacturing personnel must carefully carry out mold design according to the above basis and requirements provided by customers. When designing molds, the above contents should be specified one by one and expressed in the form of drawings and technical documents. Then let's learn about the detailed operation of the general procedures for plastic mold design and manufacturing!
Any product has its own quality, so does a set of plastic mold design and manufacturing. Some factories can only produce low-quality molds, while others can produce high-quality plastic molds. Then, let's learn about the design and manufacturing process and technological process of plastic molds!
