Technology
Rotational moulding (rotomoulding) is a manufacturing technique with many advantages that make it popular in various industries. Here are the main advantages of this method:
1. Design versatility
Complex shapes:
Rotomoulding allows the production of very complex shapes and structures, including parts with internal cavities and intricate contours.
One-piece products:
The ability to form large, one-piece products without bonding or welding, eliminating the risk of leakage or weakening of the structure.
2. Seamless construction
Products manufactured by rotational moulding are seamless, which increases their strength and resistance to leakage, particularly important in the manufacture of tanks and liquid containers.
3. Cost effectiveness
Lower mould costs:
Moulds used in rotomoulding are generally cheaper to produce and maintain than those used in other techniques such as injection moulding or thermoforming.
Short production times for small batches:
This method is cost-effective even when producing smaller batches, which is beneficial for companies producing to order.
4. Even distribution of material
Thanks to the rotary process, the polymer material is evenly distributed over the surface of the mould, leading to uniform wall thickness and greater product strength.
5. Durability and resistance of the products
Rotomoulded products tend to be robust, impact, corrosion and weather resistant, making them ideal for outdoor applications.
6. Flexibility in the choice of materials
Rotomoulding allows the use of different types of polymers, including polyethylene, polypropylene, polycarbonate, allowing the properties of the product to be tailored to specific requirements.
7. Possibility of colouring and surface finishing
This process allows products to be easily coloured in the mass, eliminating the need for painting and providing a long-lasting colour. In addition, a variety of surface finishes can be achieved, from smooth to textured.
8. Low environmental impact
Minimal waste is generated in the rotational moulding process and unused material can often be reused, making it more environmentally friendly.
9. The ability to manufacture large products
Rotomoulding is one of the few methods that allows the production of very large objects, such as water tanks or boat hulls, without losing structural quality.
10. Ability to integrate complex details
The ability to easily add complex details such as threads, handles, logos or patterns, without the need for additional operations.
Rotomoulding is a manufacturing method that combines design flexibility, cost efficiency and high product quality, making it attractive for many industrial applications.
1. Preparation of material:
The process begins by pouring a specified amount of plastic in powder, micro-granulate or liquid form into the empty mould of the product.
2. Heating the mould:
The mould with the plastic is then heated while being set in motion in two rectangular axes towards each other.
3. The melting process:
When heated, the plastic adheres in a solid layer to the walls of the mould, taking its shape.
4. Cooling:
Once the heating process is complete, the mould is cooled to allow the material to solidify and harden into the desired shape.
5. Opening of the mould:
The mould is opened and the finished product is removed and subjected to any additional finishing processes.
