Electronics Repair for Plastics & Injection Molding Plants

Injection molding machines run 20+ years mechanically, but their controllers, HMIs, and drives fail first. We repair the operator screens, servo and hydraulic-system drives, and temperature-control electronics that keep presses cycling — without the controls-migration project a replacement often forces.

Fixed — or it's free

Unrepairable units are refunded; evaluations cost $0

24-month warranty

Every repair covered, parts and labor

3–5 business days bench time

Rush (1–2 day) and emergency service available

Program preserved

Your application and settings stay in the unit

Equipment we repair for plastics & injection molding

  • Machine HMIs & operator panels
  • Servo drives on electric and hybrid presses
  • Heater-band and temperature control boards
  • PLC racks & power supplies
  • VFDs on auxiliaries

Why it matters here

  • A dead HMI idles the press even when the machine is healthy
  • OEM controls support for older presses is gone or priced like a retrofit
  • Validation and setup live in the existing hardware
