Ferromatik Milacron North America's new line of small Maxima two-platen injection machines reportedly combine a compact footprint with short cycle time and energy conservation to deliver high-performance molding capability in an economical package. Six sizes are available with 2,750 to 7,820 kN clamp force, and three models feature wide-platen configuration, allowing them to accommodate molds that normally require the tie-bar spacing of much larger machines. According to the company, an optional electric screw drive further minimizes electric consumption and allows reduced cycle time by overlapping screw and clamp functions.

In a machine footprint of 6,588 x 2,251 x 2,300 mm LWH, the smallest Maxima is a wide-platen configuration, allowing it to accommodate molds up to 3,762-kg weight and 650-mm thickness, with tie-bar spacing of 915 by 660 mm and clamp stroke of 1,060 mm.

The optional electric screw drive is said to be a perfect complement to the machine's already-short tonnage-build time of about 0.5 sec and fast clamp speed of 1,143 mm/sec, allowing simultaneous clamp, eject, and plasticating functions. In addition, the company reports that the electric screw drive reduces energy consumption to about 70 percent of that needed for a conventional hydraulic machine.

According to the company, the machine uses clever design concepts that improve operator friendliness and productivity, while keeping the machine simple to maintain, including:

  • increases in clamp stroke and daylight within a much smaller machine footprint across the product line;

  • faster tonnage build times with reduced oil reservoir requirements;

  • elimination of the need for four tie rod tonnage-build cylinders and their associated seals/plumbing common in other two-platen machines;

  • an open one-piece base to simplify shipping and setup while allowing tri-directional part removal; and

  • a wide range of international injection unit sizes from 120 to 10,100.
