The number-one difference we find is that the operator on the hydraulic machine has the tendency to set the ejector positions beyond the mold eject mechanism travel capability.

Newer electric machine designs and technology today have motors and drives with more power capability than ever before.

Machines put into service over 20 years ago are still in operation.

With good maintenance and proper operation, the annual cost has been under $500 per year.

Normal items such as grease, screw tip assembly, heater bands and thermocouples.

Belt technology has advanced over the 30 years of all-electric technology, and today’s belts can be expected to last +10 years.

Regular cleaning of the machine and observing for any lubrication issues (lack of).Cleaning or replacing the air filter for the electrical/drive cabinet.Replacement of the grease supply.Listening to the machine for any unusual noise, which might indicate the beginning of a mechanical problem.

Many factors need to be considered, and every customer will have different circumstances in making a decision to either maintain or replace their existing hydraulic machines.

The elimination of oil, valves, hoses, etc. requires less housekeeping since leaks are avoided. Hydraulic systems must have the ability to “breath” when the oil is flowing in and out of their oil reservoirs.

Hydraulic oil tends to behave differently as temperatures change and also as the oil becomes dirty.

Overlapping of operations (ie: clamp and extruder; clamp and injection - pre-injection; eject on fly) is a built-in design capability.

There are several answers to this, depending on the age and type of technology used in the machine being replaced and the molding cycle conditions.

All electric injection molding machines turn injection molding into a predictable, robotic operation.

Exacting computer controls have always been at the heart of the speed and precision of all-electric injection molding machines.

When you’re a successful injection molder with more than 40 years under your belt and more than 50 presses producing 1.8 billion containers and lids for food-packaging containers annually, what do you do when you feel the time is right to expand?

In late August, Milacron LLC, Batavia, Ohio, completed its purchase of the former Milacron Inc.

Stress-free production of large car windows, in-mold painting, and an injection unit that applies pack and hold while accumulating the next shot were a few of the cutting-edge technologies on display.
