Automatic and Manumold Injection Moulding  

Low Cost Tooling
How Do They Do That?

The tooling is often a significant part of the total cost of procuring plastic parts. The approach taken by our Project Managers to minimise the overall cost of tooling and parts includes:


Multi Section Moulding

Component Design
  • To eliminate features that would increase tooling work without detracting from the aesthetics or functionality e.g. sharp corners, unnecessarily high tolerances.

  • To design in features that add value to the part be it aesthetic or functional e.g. logo, combining two parts into one.

  • Moulding Process Selection
  • PMP offer automatic moulding and manumolding. Each has an important role and correct selection is vital for the most cost-effective solution.

  • Automoulding for higher volumes where a low piece part price is paramount.

  • Manumolding for lower volumes where the very low tooling cost (up to 70% less) is a priority over slightly higher piece part prices.


  • Detailed Internal Design Work

    Tool Design

    Principles of good tool design are applied with consideration to:

  • Expected tool life.
  • Use of in-house bolsters thereby only requiring cavity inserts to be purchased.
  • Moulding more than one part at a time (multi-impression and "family" tools).
  • Tool Procurement
  • In house for modifications and where our Project Manager needs to keep the closest contact during tool manufacture.
  • UK toolmakers selected to match capabilities with price level.
  • Far East toolmakers benefiting from lower cost and often reduced lead-time whilst our Project Manager retains control of your project.
  • We have an on site Tool Room with E.D.M machine facilities, which means reduced downtime and allows for continued production with required moderations managed on site.

    Our 'Low Cost Tooling' focus means we can offer our customers the most efficient and cost effective tooling and production solutions.
