Plastic mold design manufacturers to explain the two-color injection molding materials should meet what requirements?
Plastic mold design manufacturers tell you two-color injection molding and two-color injection molding is an important process: filling and holding pressure, then we in the molding of two-color injection mold should be how to control the injection pressure.

Plastic mold design manufacturers: two-color injection molding materials should meet what requirements?
Two-color injection molding industry is developing rapidly and the market is booming at present. Two-color injection molding process can make products look more beautiful and change color easily without spraying. However, the price is expensive and the technical requirements are high. However, the matching materials of two-color injection molding should meet two basic compatibility conditions: adhesive compatibility and processing compatibility. In addition, the following requirements should be met:
(1) The injection unit is a single-cylinder injection structure with parallel, parallel and reverse, horizontal and vertical L-shape and Y-shape;
(2) clamping mold, standard parts, vertical turntable, horizontal turntable, rotating shaft, manipulator rotating mechanism, etc,
(3) Feeding, in addition to standard hydraulic motor drive, there is ESD(ElectricScrewDrive) electric feeding structure;
(4) Mixing nozzle, special nozzle with pattern, wave, flow mark, gradient and interlayer;
(5) The oil circuit adopts ACC pressure accumulation, high-speed injection and closed-circuit design.
The above is the introduction of "what requirements should be met by two-color injection molding materials" by plastic mold design and production manufacturers. I hope it will be helpful to you. Two-color injection molding can achieve high responsiveness and repeatability and improve speed stability. Two raw materials or two colors can be formed at the same time, greatly reducing the process and manpower, and realizing cost savings. The parameters are set and the system is adjusted to a very simple digital operation.
Plastic mold design and production manufacturers talk about pressure control in the two-color injection molding process
Plastic mold design manufacturers tell you two-color injection molding and two-color injection molding is an important process: filling and holding pressure, then we in the molding of two-color injection mold should be how to control the injection pressure.
1. Injection pressure
At present, in the production of two-color injection molding, the injection pressure of almost all injection molding machines is based on the pressure exerted on the plastic by the top of the plunger or screw (converted from oil pressure). The role of injection pressure in injection molding is to overcome the flow resistance of plastic from the barrel to the cavity, endowing the melt filling rate and compacting the melt.
2. Plasticizing pressure
In injection, the plasticizing pressure varies with the design of the screw, the requirements of product quality and the type of plastic. If these conditions and the screw speed remain unchanged, increasing the plasticizing pressure will strengthen the shear, that is, it will increase the melt temperature, but it will reduce Plasticizing efficiency, increase countercurrent and leakage, and increase driving power.
In addition, increasing the plasticizing pressure can often make the melt temperature uniform, the pigment is mixed evenly, and the gas is discharged from the melt. Under normal circumstances, under the premise of ensuring good product quality, the plasticizing pressure should be determined as low as possible. The specific value varies with the variety of plastic two-color molds used, but usually rarely exceeds 20kg/square centimeter.
Today, the plastic mold design and production factory will talk about it first. I hope I can help you. Thank you for watching. I'll see you next time.

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!
