At Matissart, every extrusion-blow molding tool is the result of meticulous teamwork—and at the heart of this process lies a unique and essential profession: the precision fitter. Often overlooked, this role is a cornerstone of product quality. The precision fitter steps in at a critical stage—assembling, adjusting, and validating the mold’s mechanical components with an attention to detail that leaves no room for error.

In an extrusion-blow mold, every hundredth of a millimeter matters. The precision fitter ensures that every component of the mold—including base plates, heads, bodies, bottoms, and peripheral tooling—fits together flawlessly, meeting the functional clearances and tolerances specified in the technical drawings, and ensuring optimal sealing. This behind-the-scenes work is vital: it guarantees the durability, performance, and quality of every part produced by the mold.

The profession requires strong training in general mechanics, technical drawing interpretation, and metrology. At Matissart, new hires are supported from day one through a dedicated internal training program combining theory, hands-on workshop experience, and one-on-one mentorship from seasoned experts.
