Injection Mold Design

Guidelines in Choosing an Injection Mold Design

The importance of processing or creating plastic is not only based on the machine. Although it is where the process starts, the molding part is as important as the melting of the plastic. When the plastic has already been melted and it is transferred into the molding part where the plastic is being cool and hardened, the finished product is soon developed. However, the hard part in the molding process is choosing the right design that you must use.

When choosing your injection mold design there are some important factors that you need to consider. The first factor on the list is the thickness of the mold design. It is important that the thickness of the mold must be uniform to avoid the product from sinking, residual stress, and warping. The wall of the injection mold design must be thick enough in order for the product to have a good exterior design, which means not very thick or very thin. It must also have enough radius on its corner, which should be at least ¼ wall thickness or higher. However, it is still important that your injection mold design must be according to the size of the product that you’ll be processing. An appropriate thickness on the design will also determine the products cooling cycle. You must know the right time when the product is ready to be taken out of the injection mold design. It is also advisable to use a draft with its measurements to make the process much easier. You can also use a gusset or ribs to reduce the product’s thickness especially if it is not uniform.

Injection mold design will still vary on the product that you’ll be producing. Make a draft and calculate well the measurement so that your finish product will have a good quality.
