Design Guidelines For Injection Molding

Introduction:

Injection Molding is one of the most popularly known methods used to manufacture various plastic mould parts such as pipe fitting mould, plastic pallet mould, chair mould, automotive parts mould, home appliances mould and many more. There is some design guidelines considered while manufacturing, such as plastic mould parts.

Design Guidelines:

The manufacturer should avoid small holes, as that will lead to increasing the risks of tool breakage. This will increase your costs, so it is better to consider through-holes in mould parts. 

It is difficult to find out the variance in angle or surface consistency. The manufacturer should find out such variance if the design requires an exact angle or surface consistency.

Flatness allowed in both per unit or at reasonable values and is totally calculated as an overall tolerance. This will avoid even a small change in surface variation.

Another key thing is to consider dimensional tolerance. The manufacturer should adjust and balance the machining tool to allow dimensional tolerance. Cutter compensation used to get such tolerance.

To make easy use of plastic mould parts like plastic pallet mould, uniform screw sizes used. This design will help your customers to use it easily.

For manufacturing mating parts, it is better to consider stacked-up tolerance, as this is crucial for relating the male and female joining parts, as otherwise requires a redesign of mating parts. 

All the above guidelines strictly followed by some organizations, One such leading producer in China named HQ Mould manufacturing all plastic mould parts by following the above design guidelines. Thus, choose to buy your products from such professionals.
