High Precision Molding Design
Plastic injection mold design: To produce a complete plastic product, a good mold is the key to determine the quality of the finished product. For injection molding, both the mold and the injection machine have a great impact on the quality of the final product, and the mold even has a greater impact on the finished product than the injection machine. The following points should be considered when designing the mold :
Mold draft angleIn order to smoothly extract the molded product from the mold, the draft angle is a detail that cannot be ignored in the design and manufacturing of the mold. If there is no draft angle, there will be resistance when the finished product is demoulded, and even the demoulding cannot be successful. If the mold is deeper, a larger draft angle is required. When the draft angle is insufficient, it is very likely that the finished product will be scratched or have severe ejection pin marks during demoulding.
Rounded corners instead of sharp cornersIn order to ensure that the finished product has a consistent meat thickness, the rounded corners will be taken into consideration when making the mold. Rounding the sharp corners can not only make the finished product easier to release from the mold, but also It also allows the plastic to flow more smoothly during plastic molding. This design can also reduce the manufacturing cost of the product. Due to the reduction of stress, the product is less likely to crack during manufacturing, making it more durable.
Avoid dead corners and undercutsIf the mold has dead corners or undercuts during design or manufacturing, it will make it more difficult to demould the finished product and may cause surface scratches and other effects. Therefore, when designing the mold, try to avoid dead corners and undercuts in the mold.
Thin shell design can be used insideThe thin shell design inside the product can effectively avoid shrinkage or deformation caused by product cooling, and compared with solid products, the thin shell design can save excess manufacturing costs. In addition, when the required shape is larger, strong ribs can be added to provide additional support to the product to solve the problem of easy breakage.
