Rotoline innovates once again and introduces new fully automated machine for the production of multi-layer tanks in closed oven machine – a unique system in the market.

State-of-the-art technology, full automation, high productivity, process control and standardization, cost savings and safety. All this is guaranteed by the new Rotoline TNC30, a machine that promises to revolutionize the rotomolding industry and represents a turning point in the production of multi-layer parts/tanks, a market that has driven the project development of this machine.

The TNC30 is ideal for the production of closed multi-layer tanks, a trend in the civil construction industry, and can have different colors and materials in each layer. With an automated mold closing system, the machine is the answer to the main worries of the rotomolding entrepreneur: it allows for the production of tanks in large volumes with safety, reduction in the number of operators, low gas consumption and increased process control, guaranteeing quality products at low cost.

The new technology also results in a reduction in maintenance costs with molds and tools, another cost saving point in the production process. The feeding and weighing system are fully automated, ensuring repeatability and standardization of parts.

The manufacturing process of multi-layer tanks, previously conditioned to the use of open flame rotomolding machines, is now carried out in fully automated manner, in closed oven, which represents safety and reduction in workforce. Feeding of the second layer is done inside the oven, without the need of human intervention upon the reopening of the mold and loading of the second material, a unique process in rotomolding, according to Rotoline’s commercial manager, Kadidia Umar. “It is estimated that this machine can produce around 12 to 14 thousand tanks every 22 days. That’s around 2.35 minutes per tank. A very short time when dealing with the rotomolding process. This time can be compared to blow molding production”, she states. In order to achieve these production values in open flame machines, it is estimated that 10 to 12 open flame machines would be needed, requiring 12 operators.

As well as full process control and stability generated by the machine, enabling less movement of people and materials, the TNC30 shows gas savings. In the first tests with the machine still in the factory, a GLP consumption of around 230 grams per kg of produced material was registered. (Kg of PE).

Another true revolution offered by the innovation is the 40% saving in cooling time, guaranteed by the new internal mold cooling system. “This gain in the cooling phase enables a considerably shorter cycle time. Since the machine is made of two cars, while one station is cooling, the other already initiates a new oven cycle, optimizing production an ensuring high productivity”, points out Kadidia.
