(英文)多模加工：老技术、新方法

Saviplast (Vicenza, Italy) decided to make multimolding a key part of its strategy to deal with a stagnant market, and invested in new production cells and a skills-upgrading program to make it work. Primarily a custom molder making technical parts for European electronics, industrial, furniture, and sporting goods markets, 30% to 40% of Saviplast's production serves its own line of pump and electric motor components. Many of its products are housings, some for underwater use. Making the gaskets for these products within the mold, rather than separately, substantially increases productivity and quality.

Seeing multimolding as a key strategy to overcome a down market, Saviplast invested in a pair of two-material production cells from Mir to integrate gaskets with its broad line of pump and motor housings. A three-component cell was added later and a fourth cell is being installed currently.

To accommodate the variety of these components, three fully automated production cells from Mir SpA based on 140-, 180-, and 280-ton multicomponent injection machines from its RMPE Series have joined Saviplast's existing 27 injection systems. The 140- and 180-ton systems are two-component machines, with the second injection unit mounted vertically. Saviplast decided to forego a rotary machine platen since the gasket overmolding to be done in these cells is well suited for sliding core molds.

The multimolding strategy has proven effective. A fourth Mir production cell is being installed at Saviplast's primary factory to make an innovative component for underwater pumps.
