- 24-hour quote response
- ISO 2768 & ASME Y14.5 compliant
What we do
One team. Three disciplines. Zero handoff loss.
Most projects fail in the gaps between design, manufacturing, and automation. We own all three - so your machine ships on schedule, to spec, ready to run.
02 / MANUFACTURE
Precision Manufacturing
We turn drawings into hardware. CNC machining, sheet metal, welded assemblies, and full machine builds - all to your tolerances.
- CNC machining
- Sheet metal fabrication
- Welded structural assemblies
- Full machine integration
03 / AUTOMATE
Industrial Automation
PLC programming, HMI design, sensor integration, and electrical control panels. We commission machines that work on day one.
- PLC programming
- HMI development
- Sensor & vision integration
- Control panel wiring
Recent work
From SolidWorks file to commissioned machine.

Why AptoCAD
Engineering teams choose us for reasons that show up in delivery.
- 01
End-to-end accountability
One contract from concept to commissioned machine. No coordinating between three vendors, no finger-pointing when something doesn't fit.
- 02
Engineering rigor
Every drawing reviewed for DFM. Every weldment checked for clearance. Every PLC program documented for handover. No corners cut.
- 03
Transparent pricing
Fixed-scope quotes with milestone billing. No surprise change orders mid-project. You know what you're paying before we start.
- 04
Built for export
We work under NDA, deliver in your preferred file formats, and ship globally with documented QC. Your IP is treated with care.
Client feedback
What engineering teams say after working with us.
We came to AptoCAD with a concept and they took it from there — calculations, design, and getting the machines built and shipped to us. Both have been running without trouble since. Having one team cover the whole thing instead of coordinating a designer and a fabricator separately made it much simpler on our end.
ChrisFounder & CEO · Irwin Energy EngineeringStump Puller & Stump WasherWe fabricate in-house, so what we need from a design partner is drawings we can actually build from. Ishara's were exactly that — properly detailed, nothing left for us to guess at. We built both the feeder hopper and the screen drum straight off the drawings and they went together as designed.
JoelFounder & CEO · Arctech Circle Welding Services IncFeeder Hopper & Screen DrumAptoCAD handles the design side of our stairs, railings, and steel and aluminium doors and windows. The drawings come back clean and on time, and revisions are turned around fast even with the time difference. Straightforward to work with.
