What we solve

Get a manufacturable tool without over-buying steel

The source site positions TJ-Teck as a middle-sized toolmaker that started in 2017 with its first machine. The work is aimed at small and middle-sized projects. Engineering pages cover DFM, moldflow, 3D/2D design, and a quote menu of mold types, steels, and hot-runner brands the shop can offer.

Quote from imperfect data

2D, 3D, or a simple sketch is enough to start. If you are not a tooling expert, TJ-Teck can suggest an approach against your budget.

Lock the tool on paper first

A DFM report walks parting line, slides, draft, gates, ejection, and undercuts before construction. The design page states a good design is 60% of a new mold.

Check fill before steel

Moldflow is used to verify gating and filling, venting, cooling, clamp force, and distortion — to reduce manufacturing defects.
