The Vertical or Up and over rotational
moulding machine varies in sizes. The
sizes of these machines vary from small
size to medium as compared to the sizes of
other rotational machines. It is energy
sufficient because of the machines
compact heating and cooling chambers. It
has the same features with the Horizontal
Carousel Multi-Arm rotational moulding
machine. Only it takes up lesser space.

The Carousel machine can have 6
Cooling arms in different range of sizes. This
Oven
bay
machine has two different models
namely the fixed and the independent.
The fixed carousel machine has 3 fixed
arms that must move together. One of
the arms is in the heating chamber; the
other arm is in the cooling chamber
while the third arm is in the loading and
reloading area. The Independent
Carousel machine has more arms that
Service move separately from the others. This
area
feature will allow for the different sizes
of moulds that have different heating
and thickness specification needs.
Rotational Moulds:

The Moulds (or tooling) for Roto moulding are fairly inexpensive, and relatively
simple. The quality and finish of the product is directly related to the quality of the
mould being used. Different types of moulds used are:
Fabricated Moulds: Fabricated sheet metal tooling is most commonly used on large
parts that don't have complex design geometry and are least expensive of rotational
mould. Fabricated from steel or aluminum these moulds are formed and welded. The
welds are then ground and polished
Cast Moulds: is typically cast Aluminium or Steel cavity with flat flanges and toggle
clamp mould closing latches. The cavity is just an open space with comparatively thin
wall for rapid heat transfer. Used for parts requiring considerable detail or elaborate
shapes. They have walls polished, shot-peened for desired surface quality and can
be modified to integrate design changes.
Electroformed moulds: method for creation of tools with extremely complex
undercuts, high accuracy of cavity dimensions, form and surface definition.
