Engel injection molding machine repair in Illinois

Austrian molding machines in Illinois plastics plants

Engel, the Austrian injection molding machine builder, is a major presence in Illinois plastics plants. Engel victory tie-bar-less machines, duo two-platen machines for large parts, e-mac and e-motion all-electric machines, and older Engel hydraulic machines run in molders making medical, packaging, automotive, consumer and industrial parts across the Chicago area, often paired with Engel viper robots.

LocalSpindle techs work on Engel machines, including the hydraulics, servo drives, heats, injection units, clamps, controls and the robots and auxiliaries in the cell.

Engel machine types and what fails

Engel victory machines use a tie-bar-less clamp, which makes mold changes easier and gives more space for molds. Their clamp design has its own maintenance needs, and problems can show up in platen parallelism, clamp force or the clamp’s hydraulics. Engel duo two-platen machines are used for large molds and have hydraulic clamp, locking and platen movement systems that need regular service. All-electric e-mac and e-motion machines use servo motors and ballscrews or toggles, and their problems often involve drives, motors, ballscrews and lubrication.

Older Engel hydraulic machines are still running in many plants. They have hydraulic pumps, valves, cylinders and accumulators that wear with age, and controls that may be aging.

Engel controls

Engel machines have used several generations of controls, including the CC100, CC200 and CC300. Each has its own diagnostics, alarm system and data backup. Common control problems include display and touch screen failures, I/O module problems, communication faults and software or data issues. We back up the machine’s data before working on it.

Heats, injection and the barrel

Heater bands, thermocouples and temperature controllers fail regularly on any molding machine. A dead barrel zone, an erratic temperature reading or a zone that won’t reach setpoint can stop production. We test heaters, thermocouples and wiring, and replace what’s failing.

Injection problems, like short shots, inconsistent shot weight and screw recovery problems, can come from worn check rings, screws or barrels, hydraulic or servo problems, or process issues. We check the machine first, then help you separate machine problems from process problems.

Robots and the molding cell

Engel viper robots and other sprue pickers and robots remove parts and runners from the mold. Robot problems often look like machine problems, because the machine waits on the robot’s signals. We troubleshoot the robot, the machine and the signals between them, along with dryers, temperature controllers, chillers and conveyors in the cell.

Maintenance for Engel machines

A planned maintenance visit checks hydraulic oil and filters, pressures and leaks, inspects clamp components and platen parallelism, checks heaters and thermocouples, lubricates ballscrews and toggles on electric machines, inspects the robot and backs up machine data. We schedule around your production and mold changes.
