What should be paid attention to when designing high-precision plastic injection molding
High precision plastic injection molding has higher design requirements for this piece, and the complexity of mold design is also higher than that of ordinary molds. Therefore, all procedures must be determined before confirming the construction, so that there will be no problems during the processing. So in the design of high precision plastic injection molding should pay attention to what problems?

High precision plastic injection molding has higher design requirements for this piece, and the complexity of mold design is also higher than that of ordinary molds. Therefore, all procedures must be determined before confirming the construction, so that there will be no problems during the processing. So in the design of high precision plastic injection molding should pay attention to what problems?
1. Precision injection mold design engineers conduct economic feasibility study and analysis on the plastic product drawings that customers can provide, determine the mold industry structure, and manage the process content of product innovation design in strict accordance with regulations. This is the most important step. Attention should be paid to the careful and earnest completion, which will also save a lot of time for the next development work.
2. According to the design of precision injection mold, analyze the product expansion diagram and prepare various materials required for precision injection mold design. The material preparation according to the product expansion diagram can improve the efficiency and the accuracy of material preparation, reduce the error, and facilitate the rapid completion of the design work.
3. Determine the opening direction and parting line position of the high-precision plastic mold; Determine the opening direction and parting line of each plastic product at the beginning of the design to ensure that the core sliding mechanism is greatly reduced. Reduce the effect of parting lines on appearance. After the opening direction of the high-precision plastic mold is determined, the structural design of the product's reinforcing ribs, bayonet, protrusions, etc. should be consistent with the opening direction to avoid core pulling, reduce joints, and extend the molding time.
4. After determining the opening direction of the high-precision plastic mold, select the appropriate parting line to avoid the phenomenon of direction and improve the appearance and performance of the mold.
5. Properly adjust the demoulding angle of the high-precision plastic mold to avoid white edges, deformation, cracking and other damages on the top of the product. When designing a product with a deep cavity structure, the slope of the outer surface should be as large as possible than the slope of the inner surface to ensure that the core of the injection mold will not move, so as to obtain a uniform product wall thickness, while ensuring the material strength of the product and Open mold time.
6, each method of different plastic has its own certain wall thickness range, generally 0.54mm, when the wall thickness of more than 4mm, it will directly lead to plastic products cooling system time is too long, shrinkage and other issues, it should be fully considered by changing the market structure of enterprise products. Uneven wall thickness results in cell surface shrinkage. As well as air holes and weld lines. In addition, the reasonable choice of reinforcement design can continuously increase the rigidity of the company's products and reduce deformation.

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!
