The Problem

What Goes Wrong Here

Most tooling disputes are not about price. They are about a mold that arrived without a design record, without a trial report, and without anyone who can say why the cooling runs where it runs.

How We Take It

Our Answer

Mold making is ninety percent of what we do. Design is completed to one hundred percent detail and checked in a design review meeting before it is sent to you, and the mold leaves with trial reports and a sample dimension report.

Who This Is For

  • OEMs moving a program to an Asian tooling source
  • Product companies needing a tool and the engineering behind it
  • Buyers replacing a tool that failed in production
  • Teams needing rapid prototype tooling before committing to steel

Where These Parts Are Used

  • Two-plate and three-plate production molds
  • Slide and lifter action tools
  • Multi-cavity family and balanced-runner molds
  • Rapid prototype molds ahead of a production tool

FAQ

Plastic Injection Molds — Questions We Are Asked

How many plastic injection molds do you show?

12, all photographed from our own work. Each one has its own page with the tooling route behind it.

What is the lead time on tooling for plastic injection molds?

Lead time depends on the size of the tool, the number of cavities and the side actions involved, so we put it in the quotation rather than publishing one figure. The quotation itself comes back within two working days. Programme lead times: TBC per project.

Which mold standard will you use?

Yours if you have one. Otherwise DME, Meusburger, HASCO, Progressive or MISUMI — naming it in the enquiry avoids re-specifying components later in the design.

Will we see a design before you cut steel?

Yes. The mold design is completed to one hundred percent detail, checked in a design review meeting, and sent to you together with the DFM for comment before fabrication starts.

What do you need to quote plastic injection molds?

3D part data, the resin, the expected annual volume and the mold standard. With those four items we can quote without a second round of questions.
