Quality

Quality control in machining, checked before despatch

Quality control in machining, for us, means measuring during manufacture, a trial run before despatch, and documentation that stays with the customer.

How we check

Dimensional inspection starts during machining

A tool measured only when it is finished is a tool measured too late. By then the material has been machined, hardened and assembled, so every error costs the whole component instead of one operation.

So we measure between operations: after roughing, after heat treatment and after EDM. Hardening moves dimensions, and that movement is caught before grinding rather than after assembly.

The final check is the trial run. A trial shows what measurement cannot — how the part releases from the cavity, where flash appears, whether the cooling works evenly, and whether the tool halves align under pressure.

The same procedure applies to every injection mould and stamping die; measuring starts on the machines in our machine park, and the finished parts can be seen in the shop floor gallery.

What we insist on

Four things we do not skip

01
Checking the documentation first

Before the first cut we go through the drawing and report anything we see as a risk in manufacture or in service. It is better to argue about a drawing than about a finished tool.
02
Measuring after hardening

Heat treatment moves dimensions, and it does not move them the same way on every part. Hardened components are therefore EDM-cut and ground after hardening, to the measured condition.
03
A trial run, without exception

No tool leaves the shop without a trial. The trial is the only moment before despatch when the tool does the thing it was built to do.
04
Responsibility after despatch

The warranty is not the end of the relationship. For tools from our own production we continue service and refurbishment beyond the warranty period.

What you get

The paperwork ships with the tool

With the tool we supply the documentation a customer needs later, not only at handover: drawings of the wearing parts, details of the standard components fitted, and maintenance instructions where they are needed.

If we have refurbished a tool for which no drawing existed, the documentation we produced by measuring it stays with the customer. Next time nothing has to be measured again.
