Tesla Mechanical Designs is an outsourced mechanical engineering partner for companies that need something built, not just modelled. We turn requirements, sketches, existing equipment and half-finished CAD into models, drawings and analysis your fabricator can act on. Nothing more exotic than that.

We judge every decision against one question. How will this actually get manufactured, assembled, transported and maintained?

Send a sketch, drawing, CAD file or photograph of the problem. We will review the scope and tell you what is missing.

Our Approach

We Do Not Just Design Parts. We Engineer What Happens Next.

A mechanical design does not succeed because it looks finished on screen.

It succeeds when the parts can be cut and formed. When the assembly fits. When the load has a credible path through the structure. When a welder can physically reach the joint. When the tolerances suit the process that will actually make the part. When a technician can get to the component that fails first.

And when the fabricator has enough information to build it without calling you.

That gap, between what engineering intended and what manufacturing builds, is where projects lose weeks and budget. Closing it is the entire job.

Common Starting Points

What Are You Actually Trying to Solve?

We have a concept, but it is nowhere near ready to manufacture.

We develop the mechanical architecture, resolve the interfaces and carry it through to detailed engineering and production documentation. Product Design & Development

Our engineering team is buried.

We take defined modelling, detailing and analysis packages off your critical path, working inside your CAD environment and your drawing standards.

We still have the equipment. We do not have the drawings.

We rebuild editable CAD and manufacturing documentation from measurements, legacy prints, photographs or scan data. Reverse Engineering

Our fabricator keeps coming back with questions.

We produce fabrication, weldment and assembly documentation detailed enough to remove the ambiguity before it reaches the shop floor. Mechanical Drafting

We need confidence before we commit to steel.

FEA and mechanical calculations investigate the critical behaviour while a design change is still cheap. Engineering Analysis

What We Deliver

Our Mechanical Engineering Services

Our outsourced mechanical engineering services run the full path from concept to production release. Engage us for a single defined package, or as a standing extension of your engineering department. Both work.

Design & Product Development

Turning a requirement into a mechanical solution that can be built.

01.
Product Design & Development

concept through production handover for new products, equipment and mechanical assemblies.

02.
Machine Design

purpose-built machinery, mechanisms, frames and automation structures.

03.
3D CAD Modeling

parametric parts, weldments, sheet metal and multi-component assemblies.

Drawings & Manufacturing Documentation

The information your fabricator, machinist and supplier actually work from.

01.
Mechanical Drafting

fabrication, weldment, machining, general-arrangement and assembly drawings with BOMs.

02.
CAD Conversion

PDFs, scans and legacy files rebuilt as editable, revisable CAD.

03.
P&ID Drafting

process plants, skids, utilities and industrial piping systems.

Fabrication & Sheet Metal

Engineering that respects the cutting table, the press brake and the welder.

01.
Fabrication Design

weldments, equipment frames, skids and structural assemblies.

02.
Sheet Metal Design

enclosures, cabinets and brackets with bend allowances, flat patterns and DXF files.

Engineering Analysis

Answers before you commit the money.

01.
Engineering Analysis

structural, thermal and mechanical validation across the design.

02.
Finite Element Analysis

stress, deflection, buckling, fatigue and modal behaviour.

03.
CFD Analysis

airflow, heat transfer, pressure drop and thermal management.

Existing Products & Physical Validation

Working from what already exists.

01.
Reverse Engineering

obsolete parts, legacy equipment and undocumented machinery rebuilt as usable CAD.

02.
Scan to CAD

point clouds and mesh data converted into editable, manufacturing-ready models.

03.
Rapid Prototyping

moving from an approved design to a physical part your team can test.

Why Engineering Teams Work With Us

Mechanical engineering service
Mechanical engineering inspection

We think about manufacturing from the first sketch.

We design around how components get cut, formed, machined, welded, fastened, inspected, transported and serviced. Not around how cleanly they render.

Engineering decisions carry their reasons.

Where calculations or analysis shape a design, you get the assumptions and boundary conditions with the result. We do not bury them inside a finished model.

We work inside your system.

SolidWorks · Creo · Solid Edge · Autodesk Inventor · Fusion 360 · AutoCAD · Plant 3D · CADWorx · NestingWorks · STAAD.Pro · ANSYS Workbench. We agree versions, native-file requirements and delivery formats before work starts.

Confidentiality comes first.

An NDA can be in place before you send anything proprietary. Ask, and we will sign one today.

How It Works

How a Project Runs

01

Tell us the problem

Send whatever exists: a requirement document, sketch, CAD model, drawing, photograph or a clear description of the challenge.

02

We review the scope

We identify the required outputs, the available inputs, the technical unknowns and who owns what.

03

We agree the deliverables

CAD platform, drawings, calculations, file formats, assumptions and review points. All settled before detailed work begins.

04

We design and engineer

Function, loads, interfaces, materials, manufacturing method, assembly and service requirements, resolved together.

05

We verify and deliver

Models, drawings, BOMs and reports checked against the agreed scope, then released.

06

We support the build

Fabrication questions, supplier clarifications, prototype findings and agreed revisions, through to production.

Where We Work

Industries We Support

Our strongest work sits where mechanical design, structural behaviour and fabrication meet: industrial machinery, heavy weldments and structural assemblies, transportation equipment, process and equipment skids, sheet metal enclosures, marine fabrication, material handling, and agricultural and construction equipment.

Your Next Project Can Start With What You Already Have

Outsourced mechanical engineering services should start where you actually are, not where a template says you should be. You do not need a finished specification to talk to us. A sketch will do. So will a CAD file, a photograph of a machine, a marked-up drawing, or an engineering department that has run out of hours.

Send it across. We will review the scope and tell you the practical route from where you are to something your manufacturer can build.
