The stable machine design with a tremendously deflection-resistant clamping unit ensures high-quality rubber and silicone moulded parts. In conjunction with a DESMA FlowControl cold runner block and/or a DESFlex system competitive edges in elastomer processing are secured.
The stable clamping unit in 4-column technique ensures minimum deflection and allows for platens and hydraulic lifting devices to be precisely guided. Since being equipped with the retractable injection unit FIFO B, deflections within the nozzle area are almost completely reduced due to a minimum platen through-hole and the additional contact force of the injection unit. With the D 969.300 Z (S1) and the D 969.400 Z (S1) SEALMASTER for the field of precision seals and O-rings, DESMA developed special machines with very high specific surface compressing and high deflection resistance with compact external dimensions – just one example of many of the innovative strength of the enterprise.
Facts about the horizontal machine series D 969 / SEALMASTER
The horizontal machine D 969.100 Z (S1) sized up to a clamping force of 1,000 kN provides all equipment features of a big machine.
The clamping of 1,600 kN and the largely dimensioned clamping unit make the horizontal machine D 969.160 Z (S1) an efficient "seal machine".
The most successful DESMA horizontal machine for precision articles made of rubber and silicone - the D 969.300 Z (S1) - is fitted with 3,000 kN clamping force. Compact external dimensions, specific surface compressing and injection pressures up to 3,500 bar ensure perfect production results.
The horizontal machine D 969.400 Z (S1) with 4,000 kN clamping force is meant for high-value and efficient large-scale series.
The innovative horizontal machine D 969.560 Z (S1) is also a further development of DESMA. It is equipped with an innovative automation system.
Large clamping forces with shot volumes up to 14,200 cm³ are also available on the D 969.700 Z and the D 969.1000 Z. The opening strokes are very long in order to implement 2-deck article productions.

As trailblazer of innovative automation for horizontal machines, DESMA provides know-how for a versatile range of applications. In this context DESMA can look back on a tremendous development work.
Among other things, DESMA was able to integrate electrical axes, servo axes, laser-scanning of mould surfaces, rubber rolls, silent and highly effective brush bodies into the control systems and to establish them successfully in the rubber and silicone processing.
The article and waste sorting as well as the automatic separation of tear-trims are also part of the DESMA control technology. The automation technology is used throughout a clamping force range of 1,000 kN to 10,000 kN with shot volumes up to 25,000 cm3.
