Motoplast receives the International Innovative State-Of-The-Art and
Product Of The Year awards
yet again


Association of Rotational Molders International has awarded Motoral Oy Motoplast with the Innovative-State-Of-The-Art and the Product Of The Year for 2009. The award recognizes the best innovative and collaborative development, designing and manufacturing of a rotationally molded product.
The competition took place in Minneapolis, USA on September -09


The awarded product is the noise reduction hood of a Sandvik drill rig. The development of the product began with a demand to reduce the disturbing noise directed to the surroundings of the machine under drilling operations. Plastic construction was chosen because of its high noise reduction properties and also as the added weight to the drill rig had to be kept at a minimum. Plastic gave the best possible means to design the product as well. Rotational molding of plastic was the production method of choice, as it allowed the molding of a hollow double wall structure for the hood, which resulted in added strength as well as extra noise reduction.


The over 7 meters tall noise reduction hood consists of twelve rotationally molded plastic parts which are attached both to the drill rig as well as to each other.


Rotational molding is an option which is worth while to study before the final decision regarding utility vehicle components manufacturing method is made. With rotational molding better, more economic and competitive solutions can be achieved.
