SL Engineering
Product and engineering design, technical documentation, and design-for-manufacture consulting — the thinking that has to be right before a single part gets cut.

SL Engineering works upstream of the workshop floor: turning a problem, a sketch, or a rough idea into engineering drawings, a feasible build plan, and documentation a manufacturer can actually work from — across industrial equipment, architectural and hospitality fixtures, and early-stage hardware products.
What we do
Concept development and mechanical design, worked through until a shape is also a function.
Fabrication-ready drawings, tolerances, and bills of materials that a workshop can quote and build from directly.
An honest read on whether an idea is buildable, at what cost, and what the real technical risks are before money is committed.
Reworking a design against the realities of the process that will actually make it — CNC, sheet metal, casting, or print.
An outside engineering opinion on a stalled project, a failed part, or a decision between two ways of building the same thing.
Who we work with
How we work
Understanding the problem, the constraints, and what "done" actually needs to look like.
Working through the options and settling on a direction before detail design begins.
Detailed mechanical design, checked against the process that will manufacture it.
Drawings, tolerances and a bill of materials a workshop can quote and build from without guesswork.
A finished package, handed to the manufacturer of your choice — or to ours.
Why SL Engineering
Anyone can draw a part. The harder job is knowing which decisions actually matter — where to spend tolerance, which process will make a design cheaper without making it worse, and when an idea needs to change rather than just be documented. That's the work SL Engineering does before a design ever reaches a workshop floor.
