Below: The most common injection mould tools we can offer you e.g. automatic unscrewing tool. If you have a requirement for injection mould tools not listed below, 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. Tool cost lower than automatic c.p.tool, moulding costs higher.
Core Pulling (Automatic)	Contains mechanism to automatically produce holes & features in part/s which otherwise could not be released from the tool.	Medium-high quantities of more complex parts. Tool cost higher than manual c.p.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. Tool cost more than std. 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, Tool cost higher 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 Unscrewing (Manual)	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. Tool cost lower than automatic unscrewing tool, moulding costs higher.
Thread Unscrewing (Automatic)	Contains mechanism to automatically make & unscrew part/s with screw threads.	Medium-high quantities of screw threaded parts. Tool cost higher 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. Tool & part 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. Tool cost higher than if tool made to make e.g. just 1 part.
