Vacuum plastic moulding: technologies and advantages in production

In the production of moulds for concrete products, it is important to constantly introduce new techniques that will improve the quality and efficiency of production. One such innovative technique is vacuum plastic moulding. In this article we will look at vacuum plastic moulding technology and its advantages in the production of moulds for concrete products.

What is vacuum forming of plastic?

Vacuum plastic moulding is the process of forming plastic products by heating sheet material and drawing them inside a mould using a vacuum. This process allows to produce products with high precision and repeatability, ensuring their perfect shape and smooth surface.

Vacuum plastic moulding technologies

There are several basic vacuum forming plastic technologies that are used in the industry:

• Thermoforming: this method involves heating a plastic sheet to a certain temperature, after which it is pulled inside the mould under the influence of a vacuum. After cooling, the resulting product takes the desired shape.
• Hydroforming: In this method, sheet plastic is heated and placed inside a special mould filled with liquid. Under pressure, the plastic takes the shape of the mould. Hydroforming makes it possible to create products with more complex geometries.
• Suppression: This method involves applying pressure to push the heated plastic inside the mould without using a vacuum. It is typically used to produce thicker products.

Advantages of vacuum forming of plastic in mould production

Vacuum moulding ensures high accuracy and repeatability of the dimensions and shapes of the products, which guarantees their compliance with the project requirements. Vacuum-formed products have a smooth and homogeneous surface that does not require additional processing.

This method minimises material waste as the plastic sheet is pulled inside the mould using only the required amount of material. Vacuum forming allows for quick and efficient production of large volumes of products, which increases production productivity.

Applications in the construction industry

Vacuum plastic moulding has found wide application in the construction industry, especially in the production of moulds for concrete products. This method makes it possible to create moulds with a high degree of detail and precision, making them ideal for the production of paving slabs, kerbs, blocks and other elements of building structures.

Vacuum plastic moulding is an efficient and innovative method of producing moulds for concrete products. Its advantages include high precision, smooth surface, material saving and high productivity. This method is widely used in the construction industry and plays an important role in creating quality and durable building structures. Construction companies that focus on innovation and quality can safely adopt vacuum plastic moulding in their production.
