Grip component of Ronchi capping machine goes on 3D diet

Ronchi has been designing and manufacturing machinery for packaging liquid products ranging from foodstuffs to chemical goods and cosmetics. Among this machinery manufacturer's products are capping machines that screw caps onto plastic bottles. Ronchi teamed up with Sirris to examine how 3D printing could further increase the productivity of such units.

Founded in 1966, Ronchi is an Italian machinery manufacturer specializing in producing packaging machinery for liquid products for a very wide variety of sectors, spanning healthcare, food and pharmaceuticals. Ronchi contacted Sirris with a view to reducing the weight of the grip on its capping machine without making it any less robust, as this would allow the machine to operate faster. This provided a perfect business case for 3D printing and the Sirris Additive Manufacturing team. 

Streamlined component

Using sophisticated software, the Sirris team determined how the grip mechanism could be integrated best (i.e. weighing as little as possible) into the machine, with a topological optimization making the grip lighter. A check was also carried out on whether the grip could be made of polyamide 12, using selective laser melting, instead of stainless steel, given this sturdy plastic's noted chemical resistance and outstanding ability to withstand wear and tear.
