High-Tech is a company specialised in micro-moulding of technical parts in plastic featuring, high technical precision and small sizes (down to fractions of a millimetre). Micro-moulding is an essential process for sectors such as the eyewear industry, precision mechanics, telecommunications, technology applied to medicine and biotechnology, etc.

Micro-moulding issues go beyond the difficulties of moulding small parts, they are also about the ability to manage different reactions of materials on a micrometric scale.

For this reason, Mr Marco Belli, co-owner of High-Tech, has chosen TURRA as its partner for the production of eyewear hinge. TURRA, since 1955, has been operating in the field of engineering and manufacturing of vertical injection presses being the suitable solution for overmoulding of inserts with different sizes and specific shapes.

In consideration of the small size and the structure of the requested part, High-Tech and Turra technical teams had to implement an innovative production process dedicated to this type of product. This project is a perfect synthesis of two of our company’s technological skills: micro-moulding on the one hand, overmoulding on the other.

To meet the final customer’s requirements, one of the world leaders in the production of glasses, to the Turra RT 60 Traditional vertical press with three-stations rotary table and 30 ton injection unit, a fully-automatic production island was set up including a robot integrated with a quality control process.

Vertical presses of the RT series (available in both the Traditional and Ergon lines up to 200 tons) are in fact equipped with a rotating table with high-precision electric movement, a solution that is suitable to be integrated with automation systems to optimize the process of inserts loading and finished part unloading.

This solution has allowed High Tech to increase repeatability of overmoulded pieces and to control the quantity of the volumes with a reduction in costs that was in part dependent on the fact that labour was no longer required.
