FE All-Electric Series

The DKM FE Series are new generation all-electric plastic injection molding machines. All movements are driven directly by servo motors and no hydraulic oil is used.

Outstanding Features

• Over 95% energy efficiency — against the 30–50% efficiency of classic hydraulic systems, much lower energy consumption thanks to direct servo motor drive
• 0.01 mm positioning accuracy — suitable for medical, optical and micro part production thanks to the servo motor and the precise control system
• 10 ms response time — 10 times faster than the 100 ms response time of classic hydraulic systems; the cycle time gets shorter and efficiency rises
• No hydraulic oil — no oil change/cleaning cost, no environmental pollution from leakage, cleanroom compatible
• 5-point double toggle clamping — a computer-optimized, highly rigid toggle mechanism; mold life is extended
• Linear guide supported unit — all injection unit movements are on a linear guide, high precision and stability
• 15" HD touch screen — Techmation SANDAL II all-electric dedicated control, NET and CAN communication

Fields of Application

Medical: Blood collection tubes, Luer syringes, medical connectors, micro precision parts

Automotive: Optical lenses, headlamp/tail lamp parts, precise electronic connectors

Electronics: Micro connectors, sensor housings, portable device parts Packaging: Thin-wall packaging, caps/closures, clean production in contact with food

Tonnage Range

7 main models (between 90 and 460 tons), with 2–4 different injection unit options at each tonnage, for a total of 25 configurations. Small volume/high pressure or large volume options are offered according to your requirement.

An all-electric structure provides the highest energy efficiency and precision, but in return the investment cost is higher. For hybrid and servo hydraulic alternatives see the comparison on the injection molding machine range page.

What the absence of hydraulic oil changes

On all-electric machines all movements are made by servo motors; there is no hydraulic circuit. This has three direct consequences: the risk of leakage disappears, oil changes and filter maintenance are not needed, and the area around the machine stays clean. In medical, optical and food-contact production the last of these can be decisive on its own.

Energy and precision

Servo motors draw power only during movement; consumption at standstill is almost zero. In hydraulic systems, on the other hand, the pump runs throughout the cycle. Positional accuracy is also noticeably higher with electric drive — on small parts requiring repeatability that difference is reflected in the scrap rate.

The investment balance

All-electric machines require a higher investment than servo hydraulic ones. The decision is made by looking at the operating hours: in a plant working one shift the energy difference struggles to close the investment; in a plant working three shifts the period gets noticeably shorter. You can make the calculation with the energy and cost tools.

Its limit

On work requiring very high tonnage and a very large shot volume an all-electric structure is not economical; the FE series is positioned in the 90–460 ton band. For requirements above that, the other series should be looked at.
