Injection mould tool types that Toolcraft Plastics can offer you
Below are the most common injection mould tool types we can offer you. We also offer rapid production of steel & aluminium alloy injection mould tools. Hardened steel injection mould tools are very durable & capable of millions of parts, whereas aluminium alloy mould tools are capable of tens to hundreds of thousands of parts, are lower in cost & take less time to make

We can offer you various mould tool options e.g. a family tool or separate automatic unscrewing tools, thus you can choose the type to match your project needs.

For details of our range of conventional & CNC machines, please view our plant list or if you have a requirement for an injection mould tool please contact us.



Tool Type Definition Suitability / Comments
Core Pulling (Manual) Makes part/s with side holes & features, but needs m/c operator to manually remove tool parts to get finished part. Low-medium quantities of more complex parts. Lower tool cost than automatic cp tool - moulding costs higher
Core Pulling (Automatic) Contains mechanism to automatically produce holes & features in part/s which otherwise could not be released from tool Medium-high quantities of more complex parts. Higher tool cost than manual cp tool - moulding costs lower, larger amounts made quicker.
Family Makes several different shaped & sized parts to produce set made in same mat'l. & colour. Low-medium quantities of kit type parts e.g. knife, fork & spoon set.
Hot Runner Uses heated tool parts so std. cavity feed not needed & only parts (no waste) are made. Medium-high quantities of parts needing lower costs. Higher tool cost than standard tool
Insert (Manual) Makes parts with feature holes which enable metal inserts to be e.g. pushed in afterwards. Low-medium quantities. Cost benefits or losses depend on job.
Insert (Semi-Auto) Moulds around inserts put in tool by m/c operator to make part/s inc. metal inserts. Low-medium quantities. Cost benefits or losses depend on job.
Multi Impression Makes several identical parts. Medium-large quantities, higher tool cost than single impression, moulding costs lower, larger amounts made quicker.
Overmould Moulds around parts put in tool by m/c operator to make final part e.g. shaver plug. Low-medium quantities of parts needing encapsulation.
Single Impression Makes one part only. Low quantities, tool cost lower than multi impression, moulding costs higher.
Thread
manual
unscrewing		 Makes part/s with screw thread/s, but m/c operator needed to manually unscrew tool inserts to get finished parts. Low-medium quantities of screw threaded parts. Lower tool cost than automatic unscrewing tool - moulding costs higher
Thread automatic
unscrewing		 Contains mechanism to automatically make & unscrew part/s with screw threads. Medium-high quantities of screw threaded parts. Higher tool cost than manual unscrewing tool - moulding costs lower, larger amounts made quicker
Universal Gate position offset or moved to enable parts to be made in e.g. small m/c & split position. All moulding quantities. Part & tool costs lower than std. due to m/c efficiency.
Upgradeable Larger than if made to make e.g. just 1 part, only 1 or more impressions produce parts, with others blank, but upgradeable in future. Where moulding quantities may increase in the future. Higher tool cost than if tool made to make e.g. just 1 part
