Direct sheet molding compound (D-SMC)
This innovative one-step process eliminates the need for a maturation period, and consequently reduces the processing time from the raw material to the finished product from several days to a matter of minutes.
The direct sheet molding compounding process (D-SMC) was developed in order to further improve efficiency and quality assurance in processing. In this manufacturing process, the SMC compound is manufactured in a production line developed in house, and then hot-pressed, without the maturation time needed in conventional SMC processing. This renders the manufacturing process more consistent, producing semi-finished products with reliable properties.
As a result of the elimination of this intermediate step, each individual component making up the material, including the fillers and reinforcing fibers, can be varied during the ongoing process, allowing maximum flexibility during component manufacture. Short processing times of 20-30 minutes from the processing of the raw materials to the removal of the component from the mold increase the cost-efficiency of the process.
