ENGINEERING JOURNAL
Practical answers.
Better tooling decisions.
From a replacement insert to a production mold. Find clear guidance on machining, materials, interfaces, trials and the information a supplier needs to review your project.
Start with the decision you need to make.
Buying mold components
Blank, semi-finished or ready to fit?
Define the material condition, remaining work, inspection and fitting responsibility before comparing prices.
Before cutting steel
What should DFM and Moldflow decide?
Connect the design review and simulation to drawing changes, trial questions and acceptance criteria.
Materials & service conditions
P20, H13 or stainless mold steel?
Compare the application, finish and manufacturing route—not a grade name or hardness number alone.
Find a specific answer.
Machining & fit
CNC, EDM or grinding?
M8 tap-drill size
Replacement-insert fit
Threads & standards
Material & surface
Heat treatment and dimensions
SPI, VDI, texture and Ra

Preparing an MT Ferrule Development Brief
Prepare an MT ferrule development brief covering hole arrays, guide interfaces, material and sample conditions, tooling, dimensional inspection and optical-test responsibilities.
Before Tooling a Small Silicone Seal
Review a small silicone seal through its mating geometry, material, flash zones, insert condition, inspection and assembled function before releasing the tool.
Mold Tolerance Is Not Molded-Part Tolerance
Separate machine or instrument specifications, mold-component tolerances and finished molded-part acceptance before comparing a supplier’s accuracy claims.
What to Include in a Precision Mold RFQ
Prepare a precision-mold RFQ that defines purchasing scope, controlled drawings, materials, critical acceptance points, quantities and the real delivery milestone.
