Toolshop

Most of our Mould Tools are produced using Alumec 89 Tooling Plate, which is the ideal material for prototype tools, being cheaper to produce exceptionally high quality mould tools. These are capable of moulding extremely large quantities if required. For example, we have Alumec tools that have done 340,000 shots with minimal maintenance. It also lends itself to tool modification as required. Alumec is better than steel for our applications as it has 1/3 density, high machinability, 4 times the thermal conductivity, superior corrosion resistance and higher strength levels than steel. Steel inserts and cores are also used.

Initial high start up costs are further minimised by producing tool inserts that fit into our standard bolsters.

Tool Types Available

• Core Puller - enables holes and features in moulding
• Family Tools - makes several different sized and shaped parts eg. model car shock absorbers
• Hot Runner - no waste or sprue witness
• Insert - metal standard and bespoke inserts added to tool (either during or post moulding)
• Multi-impression - identical parts moulded at the same time
• Overmould - moulding on top of another part (moulding or metal part)
• Single impression - one part moulded by itself
• Threaded - screw thread produced from tool cavity

New injection moulds are sampled in our mould shop and sent out with an approval form. We can modify as required until the design is optimised. Once approved, an identical sample is then stored in the locked approved cupboard in readiness for production. As our Tool Setters sample, any accompanying jigs are tested and perfected for standardising production and minimising operator error. The settings are finalised and recorded for future moulding runs.The mould tools are retained on site and mouldings are ordered as required.

A single impression Injection Mould Tool created for the Manumould operator controlled machine for short-runs, can be modified at a later date to a Production Tool on an Arburg Automatic Machine with multiple impressions if so required.
