Formula, the new generation of upper injection moulding machinesInnovative and versatile, the new Stemma S.r.l. injection moulding system can also be adapted to complex production systems, like TPU film vacuum forming, varnishing directly in the mould and spray-up.

render-tactical-2The increase in the labour costs in the countries of South-East Asia is pushing footwear manufacturers to find new solutions for their productions.

In this scenario, also thanks to the introduction of lighter and better performing polyurethane materials, more and more companies are opting for “direct injection systems” for their development programs.The injection onto uppers, which so far has been used mainly to manufacture work shoes or, when possible, to contain labour costs on large-scale lines, today is a concrete alternative for sports and fashionable productions. In order to meet new needs, Stemma proposes Formula, the new machine for the direct injection of Polyurethane soles onto uppers, designed to offer maximum adaptability to increasingly comprehensive and complex manufacturing processes.

Besides traditional shoes with double density soles (PUPU, TPUPU), Formula enables the use of new systems like the vacuum in the mould for the use of TPU films, varnishing made directly in the mould and the innovative spray moulding technology.

Thanks to an extremely large mould-holder and a mould handling system patented by Stemma, Formula enables the production of shoes with a double density/hardness midsole moulded on a rubber or TPU outsole.
