Rotational molding process introduction
Rotational molding, also known as
rotational molding, rotary molding, rotary molding, rotary casting,
rotary molding, etc., the English expression is the Rotational Molding.
Rotational molding process is the first plastic raw materials added to
the mold, and then along the vertical axis of the mold and rotate the
two constantly heated, the mold of plastic raw materials in the role of
gravity and thermal energy, gradually uniform coating, melt adhesion to
the mold The cavity on the entire surface, forming the required shape,
and then by cooling stereotypes from products. In this case,plastic and
composite materials, there are many processing and molding process, in
addition to our common extrusion, injection molding, blow molding and
other processes, rotational molding is a plastic products processing
methods. At present, the rotomolding industry abroad is developing very
fast, and the rotational speed of the rotomolding industry is lower than
other plastic molding processing industry due to various factors, such
as the slow processing cycle and the materials used.
Apparently, the rotational efficiency of the product is very
low. Generally, a product take 30-60 minutes time ranging
for production, including forming, cooling, removable mold. So the
amount of product is determined by the number of molds, you have a
number of molds on the machine rotation production at the same time, it
will improve the efficiency.
