Tooling Accuracy And Why It Matters More Than Machine Specs
Why 0.002 mm on mold steel tells you more about a molder than the tonnage list on their homepage.
The Part Cannot Be Better Than The Cavity
Every dimension on a moulded part comes from a surface in the tool. A molding machine can hold a process steady, but it cannot add accuracy the cavity does not have. This is why our machining accuracy of 0.002 to 0.005 mm on ground surfaces is a more useful number than a machine count.
Where The Accuracy Comes From
Complex surfaces are completed on five axis machines, high precision detail on high speed machines, and features below conventional cutter size by spark erosion on Makino and GF equipment. Medical and plug in mold work is controlled at 0.002 mm.
Accuracy Has To Survive Production
A tool that leaves the tool room accurate can still drift in production. That is why in process checks run through the shift rather than only at its ends, and why the tool record and the lot record are linked in our ERP system.
What To Ask For In A Quotation
Ask for the machining accuracy on ground surfaces, the sampling method at tool release, and the maximum mold size and weight the shop can handle. Ours are 0.002 to 0.005 mm, cavity by cavity sampling, and 5 tonnes at 1000 x 800 x 700 mm.

Questions On This Topic
What accuracy do you hold on mold steel?
0.002 to 0.005 mm on ground surfaces, with medical and plug in mold work controlled at 0.002 mm.
Does tooling accuracy equal part tolerance?
No. Part tolerance also depends on resin shrinkage and wall section, which is why we confirm it against your drawing at mold flow review rather than quoting a blanket figure.
