4 arm Carousel rotomolding machine for water tanks in china

Carrousel rotomoulding machine is common molding equipment and each arm’s working and technological circle(rotating speed,heating temperature and time,cooling) is independent from other arms.It is fit for making products with different materials,thickness,which is flexible and high efficiency.

This carrousel rotomolding machine oven can be moveable. Its shape is round. There is only one door, so it is energy-saving and popular.

Benefits of using a rotational molding machine with a carousel:

1. The machine has three workstations that allow for efficient heating, cooling, and disassembly of molds. This results in increased production rates.

2. The machine is ideal for producing products with similar production times or for large-scale production of identical products.

3. The machine comes with an optional independent cooling station, which can include a cooling chamber if desired.

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

Siemens's programmable logic controller (PLC) enables the management of data through Ethernet using a standardized circuit.

Each arm has the capability to undergo three stages of heating, with each stage allowing for different temperature, time, main and counter shaft speed, and circulation air volume settings.

For cooling purposes, there is a cooling function that includes options such as cooling, delay, water mist, and multi-stage air cooling settings.

There is also a storage function that allows for the storage of production parameters specific to each product. The disassembly and assembly station is fixed in position to enhance efficiency.

During the disassembly and assembly process, the rotating arm is controlled remotely without the need for wires, ensuring both safety and efficiency.

Additional notes:

- The production of products can be carried out continuously even when molds are changed.

- It is possible to choose from a range of recyclable raw materials, including PE, XPE, PP, PA, PA6, and PA12.

FAQ

Q1:What is rotomolding process?
A:The rotational molding process is quite simple: A hollow mold is filled with powdered plastic resin. The mold begins rotating bi-axially and is transferred into an oven. The mold continues to rotate as the resin melts and coats the walls of the mold. The mold is cooled until the resin hardens into the desired shape.

Q2:What materials are used in rotational Moulding?
A: Rotomolding Materials Include:

• Linear Low Density Polyethylene (LLDPE)

• Medium Density Polyethylene (MDPE)

• High Density Polyethylene (HDPE)

• Low Density Polyethylene (LDPE)

• Cross Link Polyethylene (XLPE)

• EVA Co-polymer (EVA)

• Polyvinylchloride (PVC)

• Nylon.

Q3:How many types of rotational Moulding are there?
A:The types of rotational molding equipment are turret machines, shuttle machines, rock and roll machines, and open-flame machines.

Q4:Whats your companys' main products?

A:Our company is specialized in the rotational molding machines, moulds,Ice cooler box .

Q5. What is your delivery time?
A:Usually within 60 working days after sign contract and upon receipt of deposit TT transfer.

Q6. What is your payment terms?
A:50% deposit TT transfer after sign contract, and balance 50% after inspection before shipment.

Q7. How about your warrant and after-sale services?
A:All equipment unit are service one year warranty,
For electrical motor, Inverter, and PLC, we offer warranty for 18 months.

Q8. Do you test all your machine before delivery?
A: Yes, we test 100% of machine by our engineers before leave our company.

Q9. How to install and trial run when machine arrive customer's factory?
A: If the client insists to send the technician for machine installation, they will need to pay the travel fee and accommodation fee, and labor cost USD 100 for one person in one day.
