Small Electric Heating Rotomolding Machine

Small Electric Heating Rotomolding Machine is simply design. It uses an oven finned heating pipe heating,quickly heating speed,easy operatioin,easy maintenance.Due to the high cost of electric, only to produce small molds or test for materials. It also can be used as schools,businesses and other training devices.

Main Features

1) Simple structure in linear type ,easy in installation and maintation. 

2) Adopting advanced world famous brand components in pneumatic parts ,electric parts and operation parts. 

3) High pressure double crank to control the die opening and closing. 

4) Running in a high automatization and intellectualization,no pollution 

5) Apply a linker to connect with the air conveyor ,which can directly inline with filling machine . 

Mechanical Part:

It consists of an inline arrangement of a central oven that shares the two cooling/load/unload stations, one on each side of the oven assembly. The oven has a cylindrical horizont design. ROTOLINE pioneered the manufacture of machines with cylindrical oven, which provides a homogeneous airflow in all areas of the oven avoiding "dead spots".

Electrical Part:

The machine is equipped with a General Panel where are installed and interconnected all programmable and eletromechanical components such as PLC (Programmable Logic Controller), computer, contactors, motors breakers, power supplies, transformer, VFDs (variable frequency drives), push buttons, selector switches and light/sound alarms. This panel is mainly used to set the recipe parameters for the production.

Burner System:

The heating system of the Rotoline machines is done with a gas burner. The machine is supplied with a burner ready to operate with two different types of fuel gas, NG (Natural Gas) and LPG (Liquefied Petroleum Gas).

Cars/Arms:

The Shuttle machine model has two cars that can be equipped with Straight arm or optional Offset arm "C" , both built with a reinforced structure and heat treated for steel stress release.

Management Control:

The PLC is loaded with a software management control system which gathers information from multiple sensors such as temperature and pressure, installed in various parts of machine, doing all the interlock and control functions of machine operation and providing a specific and concise input to the controller of the gas burner.
