We apply the Engineering Approach to Successful Design.

"With involvement in every step of design process, we can reduce costs and delays using best practices and lessons learned making products manufacturable with consistent quality controls in place" _Onset Engineering Inc.

mechanical & Electrical design engineering services

Onset Engineering Inc. was founded by a couple of manufacturing engineers who have decades of experience in the design and manufacturing for the Medical Device & Aerospace industries, from cable assemblies, electro-mechanical systems, box builds, and more.

  • Complex Assemblies

  • Cable Harness

  • Electrical/Control Panels

  • Industrial Design

  • Design for Manufacturability

  • Design for Automation


  • Reverse Engineering

  • Tooling/Fixture/Enclosures

  • Pneumatic System

We have 3D printing farm capability, a high speed HASS CNC machine, and multiple injection molding machines. When we are assigned a design project, we design parallel with developing a manufacturing process as projected scale from our clients. Therefore, as the product is transferred from our design to manufacturing, there is no additional cost and time for design editing. In additional, everything is built locally in-house in the USA only.

As a manufacturing company, we do benefit from the long-term success of a product, therefore, we do offer an affordable prototyping services include designing, manufacturing process development for prototyping.

on-demand 3D CAD design with us

  • We estimate each project need where rates are based on the complexity of the project and the skills required. Our rate is $75/hr.
  • Design time includes all features of the design received plus any deliverables. Customer not responsible if it takes longer than expected to complete or if corrections are needed.
  • New Design changes or updates are charged at a minimum of 2 hours.
  • Functional Prototype estimate subject to change based on dramatic design changes or additional requirements.

Additional Services

Detailed 2D Engineering Drawings

We do understand engineering drawings determine the success of the projects. We are committed to providing our clients top quality design and drawings thanks to our experiences in design engineering and manufacturing. As our drawings are delivered, our clients should expect that engineering drawings be complete, clear, accurate, conform to standards, and functional appropriateness of our engineering drawings.

Reverse Engineering

With high precision measuring system, we can take hundreds of measurement and geometry recognition and re- product or reconstruct another product. This service is aimed to help customer build the same product with a different method.
