T0sample-first
From steel selection and heat treatment to machining tolerances and assembly. Inserts, slides, unscrew and hot runner are planned per project.
T0 validates dims and surface; revisions are logged. After approval we move to series or contract molding.
A STEP file, resin, rough lot and surface target are enough to quote. Hot runner is chosen by volume, scrap and gate vestige — cold runner is still right for many jobs.
Machining: CNC for bodies and cavities, EDM for ribs / sharp detail, spotting and assembly after heat treat. Cooling circuits follow cycle-time goals.

FAQ
Common questions
What drives lead time?
Part complexity, cavities, steel and hot runner needs.
Is STEP enough?

FAQ
Frequently asked
Hot or cold runner?
Depends on volume, scrap and gate vestige. High volume often hot; pilots may stay cold.
How long?
DFM a few days; tooling typically 4–8 weeks + T0. STEP clarifies.
Which steels?
P20 / 718 / H13 — by part and life.
