Rock 'n' Roll HRM Series - Rotational Molding Plants

Machine for the molding of very large items, with a rocking oven.

The only one in the market with carts that move automatically: the oven descends to enclose the cart, goes back up to carry out the tilting movement and at the end of the cycle, it releases the carts which automatically follow each other in the oven.

Cutting edge technology for rotomolding of very big parts: boats, swimming pools, kayak, silos, etc.

Designed with a rotomolding rocking oven placed on a deck structure and with one or two carts that transport the mold-holder arms horizontally from the multipurpose cooling and loading / unloading station to the point where they are hooked for the ascent towards the oven.

Large-Scale Rotational Molding

Depending on the size, the system can be equipped with a diverse number of digital fans and burners. Once the doors close, the rocking movement of the oven and rotations of the mold begin.

This unique design allows operators to work at ground level and manage all molding operations from consoles installed on the machine. Rotation of the carousels is fully automatic and the only operations required are those involved in extracting the product and loading the material, which are carried out in the multipurpose areas.

Offset or straight arms can be mounted on the mold holder arms for simultaneous production of several rotational articles. The machine provides sophisticated movement control during oven rocking, in combination with primary and secondary rotation speeds to ensure the uniform distribution of material, especially when producing hollow forms with elongated shapes, such as kayaks, or when molding and rotational machines are used for rotolining. Data settings related to cycle times, temperature and rotation speed are registered in the production recipe for each part.

Due to the size and weight of these manufactured products, it is useful to use transport and dosing systems, to ensure the best working conditions and avoid waste.
