Injection moulds have a gate which allows the plastic to be injected into the cavity of the mould. The gate can have a huge impact on the design of the cap, such as its aesthetic, part dimensions, and warping.
One of the key benefits of injection moulding is its capability to easily change sizes and even switch materials. Significantly reducing production changeover time when compared to compression moulding.
Injection moulding is well-suited for the food and beverage industry as it has the ability to mould in a tamper evidence feature, without the need for costly post-moulding operations. Injection moulding also allows for more complex geometrics forms to be created and other in-mould actions required to achieve special closure features.
