Q:

A:

Injection Molding (IM) is the most advanced typical method of molding rubber products. Injection molding produces the most consistent results by automating all aspects of how the rubber gets into the mold. In injection molding, the rubber is worked and warmed and then injected into the mold at controlled speeds, pressures and temperatures.

Q:

A:

IM will eliminate material weighing and prepping by buying direct from material supplier in strip form.

IM will reduce cure time by introducing the material into the mold cavity a preheated optimum temperature. 

Reducing cure time will reduce cycle time and make your piece/part price drop. 

IM will reduce scrap rate with a more controllable process with several new parameters. 

IM will reduce material scrap rate by producing the same exact shot volume every cycle. 

IM will improve article quality with a much more homogeneous mixture of material.

Founded in 1946, Desma Werke GMBH at Achim, near Bremen, originally produced presses for the production of shoes and soles. The name Desma an acronym for DEutsche SchuhMAschinen (German Shoe Machines). In the early sixties, Desma started to produce specialized injection molding machines for direct injection of PVC shoe soles and boots. In addition, in the early sixties, a booming market for rubber soles inspired Desma to build the first 300 and 500 ton 10-station rotary rubber injection molding machines. These machines also began to be used for the production of technical rubber parts for the automotive and consumer goods industries. Several hundred of these machines were built in the sixties, seventies, and eighties in the factory at Achim. In the year 1965, a new plant was built in Fridingen, South Germany, and single station rubber injection molding machines were developed and built in this factory. In 1981, Desma was purchased by Klockner Werke AG, a large producer of steel and various types of machinery. In 1991, the complete rubber machinery division of Desma became a separate, independent operating unit of Klockner and all activities were transferred to the expanded plant at Fridingen.  Development and production of both single station and rotary machine with clamping forces from 50 to 4000 tons and injection capacities from 100 cm³ to 32,000 cm³ are now done at Fridingen. DESMA has been active in the USA since the 60’s when Desma Industrial Machines was formed in Waltham, Mass. Since then we have grown and moved, first to Waltham, Mass., then to Erlanger, Ky., and most recently to our new plant in Hebron, Ky.
