In the field of injection mold design, Yize Mould, with its 18 years of professional experience, has assembled a core team of engineers who have unique insights and skills in gating system design. Today, let’s delve into the world of seasoned designers and uncover the secrets of their gating system design.
The gating system, as a crucial part of an injection mold, has essential design principles that are vital. These principles are mainly reflected in the following aspects:
Firstly, good ventilation design is the foundation of the gating system. It must not only guide the melt smoothly into every corner of the mold cavity but also ensure that the gas inside the cavity can be discharged smoothly to avoid affecting the molding quality.
Secondly, reducing the flow distance of the melt is key to improving production efficiency and product quality. The melt should fill the cavity in the shortest distance possible. This can shorten the molding cycle, improve the quality of plastic products, and reduce raw material consumption.
Furthermore, preventing core and insert deformation is an aspect that cannot be ignored in gating system design. When the melt enters the cavity quickly, it should avoid directly impacting the core or insert to prevent deformation. For large or high-precision plastic parts, adopting a multi-point gate feeding method is an effective solution.
In addition, avoiding significant differences in wall thickness is also a factor that needs to be considered in gating system design. Designing two or more different geometric shapes of products in the same mold is difficult. Therefore, products with significantly different wall thicknesses should be avoided in the same mold to ensure molding quality.
At the same time, minimizing heat and pressure losses is also an important principle in gating system design. The gating system should be as short as possible to reduce pressure losses and significant temperature drops during injection molding, ensuring the fluidity and molding quality of the melt.
Finally, the design of the gating system should facilitate trimming the gate and removing gate vestiges. This can not only improve production efficiency but also reduce the difficulty and cost of subsequent processing.
The above are the tips for gating system design in injection molds shared by the engineers at Yize Mold. It is hoped that these principles can provide useful references and help for everyone in the process of injection mold design.
