SPECIAL MACHINES FOR SPECIAL APPLICATIONS

DESMA offers an extensive range of special machines to fit almost all special rubber molding processes. Elastomers are used in many different industries and applications, many of which have unique requirements. In order to address the needs of our customers in these special fields, we continue to develop and constantly expand our product range. The modular nature (clamping units, injection units, and control architecture) of our machine designs are excellent building blocks to achieve optimal results. Since we have full control of our unique control system, DRC2030 TBM, the resulting special solutions can be very effectively executed.To get more news about 2k injection molding, you can visit asm-mold.com official website.

Special applications include very large machines, vertical machines with horizontally oriented injection units, machines with multiple injection units, very small machines, and machines specific to industries like oil & gas for pump stators, high voltage electrical for insulators, as well as automotive for fuel cells and battery cell gaskets.

In addition to the various special machines listed here, we also work with customers with very specific requirements to create unique solutions for their specific application.

DESMA builds specially designed machines with vertically arranged clamping units (both top and bottom acting) combined with horizontally arranged injection units. These special machines are often used in applications that benefit from the bottom heating platen being stationary during the mold opening/closing process. One such application is for the production of large high voltage electrical insulators. The DESMA 968.560 Tv and 968.700 Tv are perfectly suited for this application and can be fitted with large capacity injection units and large capacity silicone stuffers. This arrangement is ideally suitable for applications that:
Multi-component elastomer injection molding machines can be configured with two (2) or more injection units. The DESMA design approach allows these injection units to be positioned flexibly about the mold carrier, and includes the ability to retract the injection unit from the tooling automatically. This can allow the same machine which is equipped with two (2) injection units to be used with only (1) if required. Special features of this special machine type include:

Very large elastomer articles can be produced on special DESMA machines as well. These machines are used in applications like the production of tire curing bladders, filter mats in clarification systems, and large couplings for the shipbuilding industry. The DESMA Benchmark design can be employed for machines up to 13,500 kN while even larger machines like the 968.1800 ZO and 968.4000 T are also available but require different considerations due to their dimensions.

The DESMA Stator injection machine concept is truly unique in the industry. The concept allows for an essentially unlimited injection volume while achieving injection pressures of up to 3,000 bar depending on chosen equipment. This is accomplished by Stator injection machines are available with single injection units with sizes from 8,000 ccm up to 25,000 ccm while the most common dual injection unit machine is 2X 15,900 ccm.

For production of specialty seals, various unique machine arrangements are available from DESMA including small 100 ton horizontal machines with quick mold and material change capabilities up to very large machines built for EV battery gasket production with heating platens up to 2300 x 1400 mm (90.6 x 55.1 in). Multiple injection units (with or without silicone stuffers) can be employed as required for the application as well as a variety of mold handling systems.

DESMA builds machines in the C-frame style for small specialty applications as well. Known as the 956 and 957 series (for both bottom and top clamping alternatives), such presses are ideal for small articles or low volume articles. The C-frame range varies from 250 kN up to 1600 kN and includes a wide list of special equipment and injection unit options.
