Rock and Roll Type Rotomoulding Machines
Also known as rotational molding, rotomoulding is a most economical molding process for
creating hollow items especially the large hollow items of plastic. When compared to other
molding processes like injection moulding and blow moulding the tooling or die cost of the
equipment is less in case of rotomoulding. The main purpose of using this rotational molding
process is to create consistency in wall thickness and density. Machines used for rotomoulding
generally consist of parts like molds, oven, cooling chamber and mold spindles. The molds are
used to create the item where as the oven to heat the item while rotating it and the coolingchamber is the place where the hot item is placed until it cools and the spindles are mounted to
rotate to provide a uniform coat of plastic inside each mold. Manufacturing such machines for
rotomoulding using advanced technologies is what N.A. Group of Companies, an ISO
9001:2000 certified rotomoulding machines manufacturer is expert at. With sound industrial
knowledge and good understanding of customer requirements it provides rotational moulding
machines like rock and roll rotomoulding machines, bi-axial rotomoulding machines and
ancillary equipments including pulveriser, mixer, extruder, scrap grinder & MS, SS and
aluminum die casting moulds for use in various industries.

Rock and Roll Type Rotomoulding Machines:
Rock and roll rotomoulding machines are the specialized single arm machines which can rotate
up to 360 degrees in a direction and at the same time also rotate the mold 45 degrees in other
direction. These machines generally use forced hot air to heat up the mold and are the best
ones to cast large hollow parts having long length-to-width ratio. These are the ultimate heat
cost savers because of the small heating chambers that they contain. The rock and roll type
rotomoulding machines manufactured by N.A Group are the advanced machines available in
different frame sizes ranging from 1.5 x 2.5 meters to 3.5 x 7.0 meters to produce up to
10000USG capacity. Best to manufacture large hollow items especially pipes, boats up to 6.5
meters, these are the sturdy and most economical rotomoulders that can be adjusted to
different speeds for rocking and rolling for better control of the product. These machines are
also available in models of closed oven type rock and roll models with cooling station present in
it.

Bi Axial Rotomoulding Machines:
In bi-axial rotomoulding machines the mold rotates on two perpendicular axes instead of single
axis. The mold is built on arms of the machine which rotates bi-axially in side the oven where
hot air circulates to melts the resin in side the mould. As the mould rotates the resin melts under
heat of the oven and spreads to walls of the moulds to the uniform thickness product. These
mould are then transferred to the cooling chambers where the mold cools and hardens to take a
perfect shape. These machines are available in models of fix oven type and moving oven type
models. At N.A Group, we manufacture bi-axial fix oven type rotomoulding machines and bi-
axial moving oven type rotomoulding machines having oven chamber size from 1.5 meters to
6.0 meters to produce up to 5000 USG capacity. These are the most advanced models having
independent 3 or 4 arms with 4 or 5 stations for better moulding.
