Mold Manufacturing


High Performance Injection Molds

DML PLASTIC is a world class mold making facility. The high performance injection molds created by DML blend Craftsmanship with Technology. They are products that combine innovation and artistry – they are products that we, as DML, are extremely proud of.


We are able to manufacture molds with mold bases up to 2000 x 1250MM holding sizes within .005MM and positions within .01MM.

Our machines are capable of manufacturing hardened tool steel components at 62+ Rockwell.
We have machines with 3, 4, 5 axis capability (mill/turn).

Many of our machines are equipped with pallet changers and/or 3R multi station work holding systems. This enables us to run our machines unattended.

EDM Department has CNC sinkers wire machines equipped with 3R tooling, along with three robots and three automatic tool changers allowing for unattended machining.

We also have extensive grinding capabilities which include:

Jig Grinding
Surface/Wet Grinding parts up to 1150 x 1500 MM flat and parallel within .005 MM
CNC O.D./I.D Grinding parts up to 305 MM in dia. (O.D.) and 600MM long


Plate Machining: 1200 wide x1780MM long
Mold Handling Weight: Crane capacity to 9000 kg.
Average molds under construction: 60
Annual Mold Production: ~200 molds

The implementation of advanced machining and manufacturing techniques allows DML to produce all mold components in the shortest time. For example, computer workstations are located on the mold manufacturing work floor. This allows manufacturing personnel to directly query the engineering database to find reference points or an inspection datum. Efficient processes don’t just save time; they also save money.
