Full Range of Mechanical & Subassembly Solutions

MSI TEC has been modifying motors and mechanical assemblies for over 20 years. We’ve shipped thousands of high quality subassemblies to our  customers. Our Subassembly Technical Engineer Center provides electrical sub-panels for customers who prefer to keep final panel assembly in-house. Our customers cover a wide range of industries, from medical device companies seeking FDA approval to aerospace and defense.
There are many benefits of using an MSI TEC subassembly:

  • The MSI TEC quality program, process documentation, and work standards meet or exceed the highest industry standards.
  • We help you save time and money on how best to implement your design.
  • Out-of-the-box subassembly solutions.
  • With our Southern California custom stocking and delivery programs, we can deliver next day shipments to most customers.

Full Range of Solutions

We’ll work closely with you to design the most cost effective assembly for your machine. We provide detailed work instructions that include photographic instructions for assembly and test procedures for each subassembly.
