Types of injection mould tool that Toolcraft
can offer you
Below: The most common injection mould tool types we can offer e.g. hot runner tool. If you have a requirement for an injection mould tool type 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. |
