About us
3S MECH — custom part fabrication specialist
3S MECH is a custom fabrication specialist. A drawing, a photo, or a broken part pulled off the line is enough to start. We measure, draft, select the material, cut and machine it, then deliver the part assembled and ready to install.
Based in Georgia, we supply parts to nearby manufacturing plants including the Hyundai facility. Downtime is cost, so we take short-lead-time jobs and one-off single pieces without hesitation.
Our work is not limited to automotive. Jigs, tooling and motion components for rail car build and maintenance are made to the same standard.

Korea Branch MSTech · 엠에스테크
Daegu, South Korea · since 2003 · two plants
MSTech is the Korea branch of 3S MECH — an automation and precision machining manufacturer operating two plants in Daegu, South Korea. Since 2003 MSTech has designed and built automation systems, special-purpose machines and jigs, and mass-produced precision components for LM guides and ball screws.
3S MECH brings those two decades of engineering and build experience to customers on the ground in Georgia — proven Korean manufacturing know-how, with local, fast response.

Equipment we have built
Photos show equipment designed and built by MSTech, our Korea branch.
Industries
Different floors, different requirements
Automotive
AUTOMOTIVEJigs, welding fixtures, conveyor parts and inspection gauges for body and assembly lines — built to the same mounting dimensions as the original so they drop straight in.
Rail
RAILHeavy support stands, bogie supports and fitting-out workbenches for rail car build and maintenance. Load-bearing structures are checked down to the weld.
Capabilities
Drawing to delivery, one supplier
Drafting
2D drawings · 3D modeling · reverse engineering
No drawing needed. We measure the physical part, or work from photos and sketches, and turn it into a production drawing. Revisions, unit conversion (mm↔inch) and breaking assemblies into machining drawings are included.
Precision cutting
Steel · aluminium · stainless
Plate cutting, structural section cutting and hole work to drawing dimensions. Edges are dressed and chamfered so no extra work is needed at assembly.
Part fabrication
Machine elements · structures · assemblies
From structures like support bases, brackets and frames to motion assemblies using LM guides and ball screws. We source the standard components and assemble, so the unit arrives complete.
Equipment improvement
Retrofit · part replacement · upgrades
Discontinued parts, imported items with long lead times and repeat failure points are remade to equal or better spec. We also visit the floor and propose fixes for ergonomic or safety issues on existing equipment.
How it works

Request
Send whatever you have — drawing, photo or the part itself.
Review
We confirm dimensions and material, visiting the site if needed.
Quote
We quote price and lead time, then get the drawing approved.
Fabrication
Cutting, machining, welding and assembly.
Delivery
Dimensional check, delivery to site and fit-up confirmation.
