Find out how to choose the correct rotational molding machine for your business

Choosing the right rotational molding machine for your business is a very complex process that requires several researches and understanding of the subject.

Widely used by the industrial sector, rotational molded plastic represents 3% of the plastic market, a sector that is currently growing. This solution has been conquering the civil construction sector for having characteristics such as anti-corrosion, thermal and acoustic insulation, flexibility, durability, impermeability, resistance and sustainability.

But, in addition to that, rotational molding also allows the production of a great diversity of parts for the most varied sectors, such as agriculture, industry, furniture and toys. Read more about the possibilities of rotationally molded plastic.

Because of this great importance, we prepared this article on how to choose the right rotational molding machine for your business. Check out:

How to choose the right rotational molding machine

There are several types of rotational molding machines on the market. Not all models are right for your job; it is necessary to take into account that the best rotational molding machine will be the one that will meet the specific needs of your daily life. So you need to consider a few questions:

• What kind of work do you do?
• What are your goals?
• What are your expectations of the machine?
• What kind of parts do you want to produce? Big, small, cylindrical parts?
• Are you thinking of integrating accessories with the machine?
• Is there any available space in your industry where to install the machine?
• How much do you intend to spend on this purchase?

It's always good to keep these questions in mind. So you can find the machine that best suits your answers to the questions above.

Get to know Rotoline rotational molding machines

Now we want to introduce you to the rotational molding machines that Rotoline has. That way, you can have a better idea of which one is the best for your company. Check out:

Shuttle machine: technology for multiple applications

It is indicated for productions where the molds are changed more frequently, without interrupting the production process, considering that while one cart is in the oven, it is possible to change the mold of the other which is stopped. With this model it is also possible to produce with different schedules and recipes in each station. The Shuttle machine works with a central oven, two stations and two carts with straight or offset arms.

Made up of two cooling stations, it offers a special relationship between productivity and economy, in addition to the advantages of an easy mold change and the option of working with one or two stations. Rotoline has also some accessories that can be purchased:

• Dual Airlines: two airways are added to the arm, which can be activated individually or simultaneously.
• RWTC: with this device, it is possible to control the machine operation with a temperature standard, regardless of the variations in ambient temperature.
• Burner platform: allows safe access to the burner, the air extractor and the upper structure of the machine, which facilitates checks and maintenance.
• Work platforms: available in automatic or manual versions.
• Gas Flow Measurement System: it is integrated into the machine's control software, providing records of gas consumption per cycle, by number of pieces and kilos of processed material.

Carrossel Machine: sequential production in large quantities

Ideal for the sequential production of parts in large quantities, it has up to 20% more productivity compared to other machines. The Carrossel machine has a central axis, through which the arms move and pass through the various stages of the production process. Designed to work with three or four independent carts, it was developed for the manufacture of various polyethylene products.

With five independent stations, the oven, pre-cooling, cooling, loading/unloading and stand-by steps can be carried out individually. This reduces machine downtime, as each arm can be at a different station than the other. In addition, Carrossel also allows some accessories to be purchased, such as the gas flow meter and the mold temperature measurement system, RWTC.

Open Flame Machine: ideal for cylindrical parts

Open Flame machines are especially indicated for the production of cylindrical parts, such as tanks, where the distance between the burners and the mold can be closer as well as constant, which provides savings and feasibility in terms of gas consumption. With Open Flame machines, some accessories can be purchased, such as the gas flow meter.

Lab Machine: for laboratories and universities

A Lab is a rotational shaping machine developed to use in laboratories or pilot production of rotational molding for quality tests, pigments, among others. It works with a central oven, a cooling station and an offset arm cart. Even though it is smaller, this equipment has the same functions and characteristics as a large machine, that is, it allows real process and cycle simulation, the only difference being that it is electrical (it does not use a gas burner), suitable for installation in laboratories and universities because it takes up little space.

Rock and Roll Machine: more productivity and savings

A Rock and Roll, has a high standard of quality and technological development. It was developed to meet the needs of rotational molding that produce large parts. Its central oven has a capacity for seven-meter-long molds and 3 meters in diameter, enabling the production of large parts, such as tanks, boats, kayaks and so on.
