About MOLDSIA

Hands-on toolmaking experience with an engineering mindset

MOLDSIA combines hands-on toolmaking experience, precision manufacturing and applied engineering to develop plastic injection molds, industrial tooling, fixtures, jigs and technical components made to drawing.

Our work comes from the real manufacturing routine: part analysis, tooling definition, machining, fitting, assembly, maintenance and technical validation. This background helps deliver more robust, productive solutions aligned with industrial requirements.

We work both on new tooling development and on maintenance, modification and improvement of existing molds, always focused on dimensional accuracy, production reliability and execution quality.

From technical drawing to tooling in production: applied engineering to turn product design into manufacturing tooling.
