When it comes to Injection plastic mold design guidelines, there are several important considerations to keep in mind, such as strength requirements, environment exposure, resin selection and more.

Below, we outline some of the most important aspects to consider when you design for plastic injection molding.

Use
How your part will be used is undoubtedly one of the most important considerations for plastic injection molding design. While this may seem straightforward, there may be some important questions you have missed as part of this identification process, such as:

What function(s) will your part serve?
Is it a single component or part of an assembly
What market(s) is your part intended for?
What application(s) will it be used in?
Who will be handling your end product?
Will the part endure continual use or periodic?
Properties
When you design for plastic injection molding, you have to consider the characteristic properties your part will require. It’s important consider variables for:

Part Weight
Tensile Strength
Impact Strength
Opacity
Rigidity or Flexibility
Deflection Temperature
Service Temperature
High Temp Stability
Dimensional Stability
Environment
Environment is also a priority when discussing plastic injection molding design guidelines. Moisture, heat, chemicals, UV radiation, flammability and corrosion are all top environment considerations to take into account.

Depending on the environment your part will be exposed to you’ll want to consider:

Weatherability
UV resistant
Water resistant
Heat resistant
Fire resistant
Stress-cracking resistant
Corrosion resistant
Aesthetics
Aesthetics need to be addressed as part of the plastic injection molding design process. Below are some of the top questions to consider when dealing with aesthetics:

What is the size and shape?
The size and shape of a part can have a dramatic effect on how the plastic injection molding process is executed. Aspects like uneven wall thickness, thin walls, sharp corners and complex geometries will all affect how the final part will be produced.

Are there brand identity requirements?
Some parts may require brand compliance, which may include color, imprints, logo, labeling, packaging, etc. It’s important to understand any brand identity requirements prior to starting the plastic injection molding process.

Does your part require a particular surface finish?
Depending on your parts function and end-use, your part may need to possess a finish that’s smooth, high gloss, matte or textured.
