Engineering & Design
Mull Group's in-house mechanical engineering team — CAD drawings, reverse engineering, engineering studies, failure analysis, and capacity upgrades.

Mechanical Engineering.
In-house.
In-house.
Our in-house mechanical engineering team produces all drawings, engineering studies, and analysis work — for our own manufacturing and as a standalone service for customers. Reverse engineering, capacity upgrades, failure analysis, and CAD work the OEMs won’t do.
- Our Approach
Every drawing we ship. We draw ourselves.
Most machine shops run on OEM drawings. When the OEM drawing is wrong, obsolete, or unavailable, the shop stops. Mull Group has its own mechanical engineering team — real engineers with real CAD stations — doing the design, analysis, and drawing work that keeps our manufacturing moving and that we also offer to customers as a standalone service.
If your OEM has vanished, your print is 40 years old, or your equipment is failing because the original design didn’t account for today’s tonnage — we can study it, redraw it, analyze it, and upgrade it. You don’t need a consulting firm. You need engineers who also know how to build what they design.
- Three Ways We Deliver
Study the problem. Draw the solution.
Upgrade the design.
01
Studies & Analysis
Engineering studies that answer the "why is this failing?" question — and the "how do we fix it?" question that follows.
- Failure root-cause analysis
- Design integrity review
- Load / stress calculations
- Feasibility and concept studies
02
CAD & Drawings
2D prints and 3D models — production drawings that your shop or ours can build from.
- Production drawings with full GD&T
- 3D solid models (STEP, Parasolid)
- Assembly drawings and BOMs
- Revision control and drawing management
03
Reverse Engineering & Upgrades
When the OEM is gone or the original design can't handle today's load — we measure, redraw, redesign, and document.
- Reverse engineering from physical sample
- Capacity upgrade redesign
- Obsolete component replacement design
- Complete as-built documentation
- Capabilities
Engineering capability. Verified.

- Typical Engineering Work
What we get asked to figure out.
Obsolete OEM Redraws
Rebuild drawings when the OEM is gone.
Capacity Upgrades
Redesign for higher tonnage or speed.
Failure Analysis
Root-cause reports with photo and data.
Reverse Engineering
Physical sample → production drawing.
Design Integrity
Review existing design against current loads.
Component Redesign
Replace failing components with improved versions.
Assembly Design
Multi-piece assembly drawings and BOMs.
Feasibility Studies
"Can this be done?" — with the math to back it.
