Modular machine concepts for the rubber and silicone industry
State-of-the-art and flexible machine concepts are the basis for successful turnkey packages. The open control architecture of the injection moulding machines of DESMA enables the integration of complex automation systems as well.
Innovative mould shop
With the in-house DESMA mould shop new ideas are realized in a hands-on and process-oriented way. Short ways in the production process ensure steady success of the enterprise in the rubber and silicone industry in the long run.
Worldwide service and hands-on transfer of knowledge
Especially for extensive complete systems DESMA provides project-focused classes in order to ensure an efficient introduction into your production. The knowledgeable DESMA service team is available for you around the world and keeps your production running.
The experienced DESMA project engineers support and advise you from project engineering to run-off tests. In the realization phase the engineer in charge of your project is your contact. Thus DESMA guarantees a seamless communication.
New methods for elastomer processing are developed and made ready for the production stage by versed application technicians and process engineers in the DESMA process engineering center - a state-of-the-art test center at the Fridingen location. It goes without saying that the cooperation between DESMA and their customers is particularly close in the development phases.
The margins in the market for elastomer technology are globally under high pressure. The investment expenditure is here often overrated as against the total cost of ownership. DESMA looks also at costs that arise in addition to the investment and the depreciation involved. Thus among the total costs of ownership are mainly the utility costs as well as the expenses for personnel, maintenance, efficient material usage, quality, floor space required and productivity. These costs contribute to the same degree as the investment charges -frequently even more - to the total part costs.
The DESMA construction and project engineering philosophy serves the single purpose of creating customized added value solutions for more efficient production processes.
Three significant examples taken from DESMA's practical experience are described in the following.

The production of Viton seals was realized through a DESMA 14-nozzle FlowControl cold runner block. The annual production time amounts to 6,000 hrs with an average efficiency factor of 85 %. With a material price of 20 €/kg and a runner weight plus waste of 5 grammes, it results an annual cost advantage of 95,331 €. The one-time extra investment amounts on the other hand to 75,000 € (CRB + temperation units + triggering).

For a LSR adapter production with hydraulic parallel movement and a closing time of 6 seconds, the degree of utilization can be raised to 98,710 cycles. The production volume rises accordingly to 592,258 pieces. With an article price without material costs of 0.6 € it is possible to save 8,527 € per year. The one-time extra investment amounts to 5,500 € only.

The manufacture of a valve bonnet gasket is feasible in 2 decks on a D 968.400 ZO. Here the cure time amounts to 90 seconds and the cycle time to 140 seconds. The increase of the number of cavities from 4 (with 1 deck only) to 8 in this procedure allows for an annual production volume to be doubled from 564,923 to 1,049,143 pieces. The machine-hour rate rises with the multiple-deck production, i.e. with a second mould deck to 125 €. The production costs per article go down from 0.797 € to 0.715 €. This corresponds to a cost advantage of 39,560 per year. Customers are thus in a position to save one machine. Numerically it is 250,000 €.
The video examples show your potential cost savings in terms of total cost of ownership with innovative DESMA injection moulding machines.
