Danish Rotations Plastic ApS was founded in 1965 by Ib Endsgaard.
Danish Rotations Plastic ApS (DRP) is a 100% family owned special factory for rotationally molded plastic.
Ib Endsgaard handed over the control to his children, Michael Endsgaard, Hans Endsgaard and Vicki Endsgaard, in 2001. In present time, they oversee the holding company's daily operations and they are responsible for approximately 20 employees.
With our more than 45 years combined experience in rotational molding, DRP, both in the private and municipal sector, solved many special projects within rotational molded plastic parts.
Therefore with years of experience, we have solid knowledge of the industry, and currently we cover a large part of the Danish and European market.
In 1976, an international association of rotation-moulders formed. It was called "ARM": Association of Rotational Moulders, and DRP has been a member ever since.
Hereby, we have a very large and international network, so DRP is truly one of the pioneers in rotational molding.
It is a process in which an outer shape of metal, or aluminum, is heated during rotation, and the molding of thermoplastic materials made from powder is formed into finished cavity-topics, of virtually any shape and size, limited by the capacity of the rotary.
The advantages of the process are: Low cost forms, small series, potential subjects, colors to order, quick delivery.
People were desperately seeking for a technique to produce large plastic items in a reasonably easy manner. They made experiments with molding polyethylene granules in some primitive iron molds, which were warmed up and the result was thereafter.
One could not melt granules into finished tubs, but the possibilities were apparent. Plastic Powder was the case, it could be seamlessly fused into finished products. For many years, only simple rotation about an axis was used. It was much too difficult to fill the molds entirely with powder and after a time drain the excess material out again, and shiny products are finished.
Double rotation is the thing to do today and has been for many years. The rotation is set by product form and nature, and one can thus obtain a uniform thickness within approx. 1mm.
New high-tech churns provide complete uniform powder.
