Sample Testing & Feasibility Evaluation

Before building a custom automation line, we can evaluate your product drawings, 

materials and assembly requirements.

For suitable projects, sample welding validation can be arranged. Tooling or fixture cost

may apply depending on product structure.

This helps reduce development risk and confirms process feasibility before production.
