There are many factors to consider when designing for manufacture through injection moulding. To ensure your design is smooth and the injection mould is successful, here are four design guidelines to follow:
Keep It Simple
Design is about uncomplicated, clean-lined products that are functional. Simple shapes, lines and curves will have your design looking fashionable and aesthetically pleasing.
Avoid Undercuts
Think about where the parting line will need to be. Avoid protrusions that will snag on the mould when it is opened.

Design for Ease of Production
Don’t make everything a challenge for the Toolmaker. Part of product design is creating something that is both pleasing to the customer and relatively easy to manufacture.
Using Standards
When designing your product, don’t specify odd-sized screws and hard-to-source materials. Designing with ‘off the shelf’ standard components in mind will keep your design both efficient an affordable. People will want to use something that is easily maintained, so make your design with the end-user in mind.
