The trend towards customised shoe production in particular has far-reaching consequences, with steadily decreasing batch sizes. Thanks to Desma machinery, however, mass customisation has already become reality.
At the same time, footwear manufacturers have to reconcile the growing demands of their customers with production processes which are not only cost-effective, but which also ensure minimum impact on the environment. This balance can only be achieved with automated processes and the use of innovative technologies. And this is where Desma can help with its innovative production solutions (Industry 4.0), highly automated machinery, professional excellence and comprehensive support.
The heart of the Desma portfolio is its direct soling systems, which mould soles made of polyurethane, rubber, thermoplastic polyurethane or other synthetics directly onto the uppers. Desma rotary tables with 18, 24, 30 or 36 clamping units are designed as modular systems which can be equipped with a large variety of extras, enabling them to deliver the optimum mixture of a high degree of automation and manual functions. The sole material is directly injected and combined with the upper, thus ensuring perfect adhesion between upper and sole. The sole material surrounds the upper, which means there are virtually no limits when it comes to designing creative soles, different combinations and special effects.
In response to the trend towards customisation, Desma has developed Multi Section Injection (MSI) technology, for example. Material injections into various sections of the sole can achieve different properties, such as hardness; what’s more, this can be individually controlled, changing from shot to shot. This offers the wearer optimum comfort, energy absorption and stability.
Two new processes called Centre Wedge and DESwing now make it possible to enlarge the range of design options and/or the range of features for multi-coloured soles as well as the mix of different materials. These new methods are achieved in a combination of mouldmaking and machine control, delivering a wide range of benefits for the customer. Desma has also developed an In-Mould Labelling process in which the use of integrated plastic sheeting or textiles creates new product varieties for the outsoles, giving a virtually unlimited choice of colours and colour effects for the shoe.
