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.

Design Rules for Injection Moulded Products



Injection Molding is a versatile process easily applied to manufacture all kinds of mould parts. Injection Molding is the industry standard and even custom mould maker makes use of plastic injection molding process to design custom mould plastic parts. Here will see some few design rules to ensure quality and durability.

Maximum Wall Thickness:

The wall thickness of plastic part is directly proportional to both the cooling time of process and the total materials required to produce the plastics. When you decrease the wall thickness, it will help to decrease the cycle time and production costs as well. If the wall thickness is too high, then it will lead to the problems like sink age and war page, where one has to redesign the product again.

Corners:

If it difficult to force the plastic into a perfect corner, which results in messy product. Thus, mark all the corners to increase the aesthetic and durability.

Applying a Draft:

A draft is a tiny angle ranging from one to two degrees. This angle applied to the mould on the face perpendicular to the parting line. Draft will allow for easy removal of any portions from the plastic mould. Custom mould maker makes use for this design feature to correct the defects in the products.

Ribs:

Ribs are another design feature needed to acquire the overall stability control. Ribs will give greater structural support, as they add as thin wall protrusions. Manufacturer like HQ Mould considers all the above design features, to manufacture their plastics with zero defects.
