What are the structural components of the Rotomolding Machine?

The Rotomolding Machine is so called because it has a central axis through which the trolley moves in different stages of the production process. It is designed to work with three or four separate carts, and the machine was developed for the manufacture of many different polyethylene products.

What should we pay attention to during the use of Rotomolding Machine?

The Rotomolding Machine may not be suitable for high volume manufacturing. The slow rotation during heating to the molten state and the gradual cooling of the part and the entire tool to room temperature after the mold consumes a significant amount of time during the molding cycle. Cooling water or air systems can be used, but at an additional cost.

Finally, the process still involves manual steps (e.g., demolding) due to the limited availability of automated features.

What is the form of the Rotomolding Machine?

The standard setup for Rotomolding Machine operation includes arms or stands to carry the molds, single or multiple ovens and cooling chambers. The only difference between the machines is the direction in which the molds travel, following the sequence of the rotomolding process. The types of machines used in the rotational molding process are as follows.

Flip-top Rotomolding Machine: Flip-top machines are single-station machines in which molding and cooling occur in a single chamber. The mold with resin is loaded and unloaded in the chamber through the front panel. The front panel and cover are locked during heating and molding. After molding, the cover is opened for cooling, allowing the mold to swing out of the open oven.

What are the structural components of the Rotomolding Machine?

The Rotomolding Machine is designed with a high capacity air recirculation system (with variable frequency drive for start-up and speed control) and an efficient heating system for each cycle. The trolley can be equipped with a "central" arm (straight) or an optional offset arm ("C" or "L"). Geared motors and variable frequency drives allow to adjust the axis speed in any direction of rotation.

2, Rotomolding Machine is equipped with a main panel where all electromechanical and programmable components are mounted and connected. It is also equipped with two independent control platforms for each site, providing the operator with three places for control and operation. All panel connections to the field devices are made using quick plugs (plug and play), thus reducing the time required for installation. It also features a complete electrical design that is easy to interpret, allowing for quick inspection and maintenance agility.

3. The Rotomolding Machine's Programmable Logic Controller (PLC) is loaded with a software-managed control system that collects information from multiple sensors (such as temperature and pressure) installed in various parts of the machine, performs all interlocking and control functions for machine operation, and provides concise input for specific gas burner controllers.
