The Plastic injection molding China offers versatile solutions for manufacturing variety of applications. It also helps in producing high quality parts at low cost. This process is surely far better and beneficial in comparison to other molding processes, but the success of any part depends upon its design. The design can affect a lot in consistency and efficiency and poor design can be more costly and time-consuming. So let’s just discuss few design elements that should be taken into account while applying plastic injection molding China process to achieve quality and precision of the parts.
Thickness of Wall
Now you have the flexibility of reducing injection molded part defects by laying out a smart and well designed wall thickness design. Keep in mind that the thickness of all walls should remain uniform as molten plastic will try to come out of the path of the larger walls leaving the smaller wall areas unfilled. So a thoughtful design layout will play a great role in achieving the accurate and refined injected molded parts.
When you are doing high volume production with plastic injection molding China process, the plastic parts having extreme features can become susceptible to defects as molten plastic always flows from the path that offers the least resistance to it and harsh and sharp angles can prevent the molten plastic to move. So, it is very important to keep all corners curved and therefore it is recommended to have smooth corner transitions for better plastic flow.
These weld lines occur when two sections of a single flow meet. They occur mostly around holes or any other type of obstructions where the plastic flow separates them in order to pass through them and then fostering them to come back together afterward. The injection molded part produced by plastic injection molding China has weld lines and your objective should be to design your part so that the weld lines occur at places where they don’t impact on part’s strength.
