9 Tips to Reduce Injection Moulding Costs

In our new injection moulding design tip we provide practical advice on keeping your manufacturing costs to a minimum.  For example, did you know one of the easiest ways to reduce price per part cost is by increasing your order quantity—this is because up to 25,000 parts can be moulded from the same tool.



Read Tip

Walls in any moulded plastic part should be no less than 40 to 60 percent that of adjacent walls, and all should fit within recommended thickness ranges for the selected material.

The deep-rib approach (left) shows a box designed with walls as rubs, resulting in higher a cost to machine and polish the mould cavity. With the core-cavity approach (right), the box allows features to be milled with a faster cutter, and is easier to polish. This saves you time and money.
