A Repair Bench for Machine Builders & System Integrators

When your customer's machine is down on hardware you shipped years ago, you need a bench you can trust with a straight answer and a fast turn. We work behind integrators and OEM service teams daily — reseller pricing, blind-ship options, and honest evaluations you can forward to your customer.

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 machine builders & integrators

  • ▸Every HMI family we service
  • ▸Servo drives & VFDs
  • ▸PLC modules & supplies
  • ▸Legacy hardware your OEM no longer supports

Why it matters here

  • ▸Your name is on the machine even when the component failed
  • ▸Obsolete hardware in the field, no stock on the shelf
  • ▸Margins need a wholesale repair price, not retail

How mail-in repair works

  1. 1

    Start your repair online

    Buy a flat-price repair or request a free evaluation. Either way you get an RMA number and shipping instructions instantly.

  2. 2

    Ship us the unit

    Pack it well, write the RMA on the box, and ship to our Dallas–Fort Worth lab with any carrier. Packing guides are in your confirmation.

  3. 3

    We diagnose and repair

    Bench diagnosis, board-level repair with quality components, aged capacitors replaced as standard, then full functional testing. Quote-track units get a firm quote for your approval before any work.

  4. 4

    Tested, returned, warrantied

    Your unit ships back with the return speed you chose — covered by a 24-month warranty, with your program and settings preserved.
