What your process engineer actually checks

From printed prototype to molded part

We use injection molding to bridge our own printed prototypes into short runs, so install includes validated parameters for your resin and tooling guidance. The team that trains you actually molds parts — not a distributor reading a manual.

About this product

Swap mold inserts in minutes on your APSX-PIM

The MUD (Master Unit Die) base is a universal mold frame for the APSX-PIM desktop injection molding machine. Mount a 3D-printed or machined metal mold insert, align it on the pre-installed guide pins and bushings, and start molding — then swap to the next insert without redesigning your clamping scheme.

Rapid changeovers — swap inserts without a new clamping setup
Dense ½″ mounting grid of 1/4-20 threaded holes for flexible hole patterns and secure insert retention
Repeatable alignment and consistent insert positioning, shot after shot
Ideal for prototype molds, low-volume production, and education/training

Built for 3D-printed mold inserts

Print mold inserts in rigid, high-temperature tooling materials (high-temp SLA/DLP tooling resins or 3D-printed metal), bolt them to the grid, and iterate mold designs in days instead of weeks. Mold inserts are not included. Note: there is no temperature-sensor hole for 3D-printed inserts, and a mold insulator is recommended to keep mold temperature stable over longer runs.

No high-temp tooling printer in-house? Additive Plus prints mold inserts to your CAD — materials advice included. Get in touch →

Pairs well with the APSX-PIM Plastic Material Starter Kit for process tuning on new molds.

FAQs

Does it include mold inserts?

No — the base ships with bushings and guide pins installed; you mount your own 3D-printed or machined metal inserts. Additive Plus can also print inserts to your CAD.

What insert mounting does it use?

Each half carries a 9×7 grid of 1/4-20 threaded holes on a 0.500″ (half-inch) pitch, so you can bolt down inserts, clamp bars, and custom retention plates in flexible patterns.

Which machine is it for?

The APSX-PIM desktop plastic injection molding machine.
