Mould Tools made in the UK

At Pentagon Plastics we offer a range of tooling options for our customer from part owned modular insert systems through to fully owned and dedicated mould tools to manufacture your bespoke products.

The complexity of the fully owned tooling solutions we provide is dependent on the intricacy of the component and volumes required in production. The starting point would be a simple mould tool construction manufactured within soft alloy or mild steel tooling die sets. The most cost effective tools are straight open and shut however loose inserts or very basic side actions can be incorporated to produce side holes, latch features or small undercuts even on quiet basic tool configurations.

Simple tool construction will often have the form of the product cut directly into the core and cavity plates to keep cost down. Our recommendation in these instances is to supply the tool plate in a P20 pre-toughened steel to extend the tool life and reduce wear and tear issues.

This form of tooling will allow for improved temperature control over a modular insert system as dedicated waterways can be designed in to the bolster set which allows you to mould a greater range of thermoplastic materials. Simple mould tools can produce parts in many non-filled thermoplastic materials such as TPE, EVA, PP, PE, ABS and Nylon as an example but would not be recommended for filled materials or harder plastics like PC or PEEK.

Features of a simple mould tool:

  • Basic tool construction
  • Soft alloy or mild steel die sets
  • Form can be cut direct into pre-toughened plates
  • Simple product features
  • Wide range of thermoplastic materials
  • Dedicated temperature control
  • Price range from £3,000 to £6,000 as a guide
  • Lead time for manufacture and sampling 4 to 7 weeks

For the manufacture of more technically challenging components were a more complex tool construction is required we will manufacture vacuum hardened insert systems that will be housed in a mild steel or pre-toughened die set unit. By incorporating hardened steels into the construction of the tool we can maximise the tool life by reducing the wear impact. Although our tools are producing parts in plastic overtime the tool will become worn if the correct material for the application is not used. Many thermoplastic materials also contain fillers such as Glass which is abrasive and can accelerate wear issues.

Hardened mould tools should be used for all filled materials and high engineering grades such as PC, PPS, PEEK, PEI or PES as examples.

Features of a complex mould tool:

  • Intricate tool construction
  • Mild steel or pre-toughened die sets
  • Hardened tool inserts
  • Detailed product features
  • Full range of engineering thermoplastic materials
  • Comprehensive temperature control
  • Price range from £6,500 to £35,000 as a guide
  • Lead time for manufacture and sampling 6 to 14 weeks

The completed tools are held on site of manufacture here in Horsham where we carry out routine preventative maintenance between production runs. The fully owned tooling option means that the completed tool is portable should the customer chose to re-locate it.

The manufacture of all tooling provided by Pentagon is carried out by our highly skilled in-house toolmakers. This provides customer confidence and one point of contact throughout the injection moulding process.
