What are the production characteristics of the Rotomolding Machine?

When the Rotomolding Machine is processing, the rotational speed of the mold is not high, and the molding of the product depends on the natural flow of the resin, so the product has almost no internal stress, and is not prone to defects such as deformation and depression.

What are the production characteristics of the Rotomolding Machine?

The polymer resin must have high thermal stability, flow easily in the molten state, and have antioxidant groups in the molecular structure. The resin must be easily ground into powder form. Polyethylene is the most commonly used polymer.

The advantages of using Rotomolding Machine are the ability to make parts with uniform wall thickness, inexpensive tooling, production flexibility, fewer downstream processes, and less resin waste. Large double-walled parts are also easily fabricated.

The disadvantages of rotational molding are long cycle times due to long heating and cooling cycles, limited material selection, short tool life, and difficulty molding certain details.

What are the features of the Shuttle Rotomolding Machine?

The Shuttle Rotomolding Machine has independent two-axis rotating arms that move the mold from the loading, cooling and unloading (combined stations) to the heating chamber located in the middle of the track. The mold returns to its original position when the process is complete. The shuttle facilitates maximizing the footprint.

The Shuttle Rotomolding Machine runs individual molds continuously rather than waiting for one mold to cool before starting a new cycle. Plastic is injected into the first mold and the second mold is shuttled into place. As the first mold cools, the second mold is clamped and the plastic is injected into it and sent to cool. Once the second mold is sent to cool, the first mold is ready to begin the process.

What are the production characteristics of the Rotomolding Machine?

The Rotomolding Machine is ideally suited for high-volume continuous part production and offers up to 20% higher productivity compared to other machines. With five separate stations, oven; pre-cooling; cooling; loading/unloading and standby steps can be performed separately, reducing machine downtime as each arm can be at a different workstation.

For the Rotomolding Machine, accessories can be added, such as a gas flow meter. It is integrated with the machine's control software and provides a record of gas consumption by cycle, number of parts produced and weight of material processed.

Another option is the wireless temperature control system RWTC, which finds the standard system behavior that produces the ideal oven temperature to form parts with quality and repeatability. The system uses temperature self-regulating oven time control instead of using programmed oven times, which avoids the influence of final external temperature differences (e.g. ambient temperature) and minimizes gas consumption for part manufacturing.
