Plastic speaker shell for rotational mold machine OEM service

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.
