Rotational moulding machine rotomolded furniture rotomolding machine for sale

Shuttle style rotational molding machine is placed along a straight line with oven and two trolleys with arms in its center. Cooling chamber and loading station in both sides. When a trolley on one side rotating the mould into the oven to get heated, the other trolley will stop other side to load or demould.

In this way, the operation is flexiable for manufacturing comparatively large product. Even for comparatively small product, productivity is high. Besides, equipment is relatively simple and easy to be maintained. At present, this kind of rotational molding machine is broadly used in our country.

MECHANICAL PART

The equipment is modularly designed and manufactured; 

The cylinder oven has high space utilization and low heat absorption; 

Anti-deformation design of the oven door contributes to improve security; 

Real-time monitoring of oven temperature helps reduce energy consumption and improve efficiency.

Oven: it passed the CAE test and verification and the temperature in the oven is uniform；

Heating chamber: 1. The hot gas is blown into the oven through a circulating fan below the heating chamber, and the remaining hot air can flow into the heating chamber through a suction outlet at the top. This design helps makes the powder less likely to accumulate and thus prevents fire. 2. The interior of the heating chamber is made of stainless steel, which is durable. 3. The thermal cycle fan and dual cooling system are conducive to durable and stable output.

Rotating arm and head: they are totally enclosed design and adopts casting and forging process, whose performance is improved to be safe and reliable after heat treatment.

Bearing capacity of rotating arms: Mechanical CAE Analysis.

Ventilation function of rotating arm: adjust its thickness to be uniform; Environmental protection device for waste gas recovery can reduce exhaust gas emissions, improve the environment of the workshop.

COMBUSTION SYSTEM

Different kinds of burners are selectable, like Weishaupt(German brand) and Maxon(American brand ) and Riello(Italy brand), which can be heated using natural gas, liquefied petroleum gas, diesel oil, and electricity.

CONTROL SYSTEM

PLC control: Siemens’s PLC manages data over Ethernet with standardized circuit.

Each arm can be set up three stage heating, and each stage can be set up with different heating temperature, time, main and counter shaft speed, and circulation air volume.

Cooling function: cooling, delay, water mist, multi-stage setting of air cooling;

Storage function: store production parameters of corresponding products;The position of disassembly and assembly station is fixed to improve the efficiency ;

Disassembly & assembly process: rotating arm is wireless remote-controlled, which is safe and efficient;

REMARKS

Be able to continuously produce products when the molds are changed. Selectable raw materials：PE XPE  PP PA PA6 PA12；100% recyclable.
