Modern industry faces various challenges, one of which is the control of high temperatures in multiple processes. In this instance, thermal insulation guarantees the safety, efficiency, and quality of equipment and systems.

According to a study by the American Society of Mechanical Engineers, thermal insulation can help improve the efficiency of industrial processes by up to 15%.

In this article, we will explore vacuum-formed shapes made from insulating fiber. These shapes offer excellent thermal properties and versatility, making them ideal for various industrial applications.

We will explore their characteristics and manufacturing process, highlighting the options offered by NUTEC, a leader in the industrial thermal insulation sector.

What Do We Mean by Vacuum-Formed Shapes?

Vacuum-formed shapes are custom-made products developed using a wet forming process involving multiple fibers and binders to create a product which is then dried and finished to the desired tolerances. These shapes are designed and manufactured for the specific needs of various industrial sectors.

Vacuum-formed products can be made with organic or inorganic (smokeless) formulations to meet product requirements. Also, they are available with particular densities upon request, and in various shape configurations.

What are the Benefits of Vacuum-Formed Shapes?

These products offer many specific benefits due to their chemical and geometric properties. Mentioned below are some of the key benefits.

  • High thermal resistance. They offer excellent thermal insulation capacity, resisting extreme temperatures and minimizing heat loss in industrial equipment.
  • Low thermal conductivity. Due to their fibrous structure and low thermal conductivity, these products minimize heat transfer, ensuring greater energy efficiency.
  • Resistance to thermal shock. They are highly resistant to sudden changes in temperature, which prevents damage to equipment and guarantees a longer useful life.
  • Versatility. They can be tailor-made to specific shapes and dimensions, making them suitable for various industrial applications.
  • Lightness and ease of installation. Despite their strength and thermal performance, these components are lightweight and easy to handle and install, simplifying the assembly process.

Vacuum-Formed Shapes – Engineering Process

The manufacturing process of vacuum-formed shapes involves a series of stages, which we will address below.

  1. Customer concept. The process begins with the customer's vision, who may have a sketch, 3D model, or drawing of the desired shape. The concept should comprise the desired shape, size, materials, and technical characteristics.
  2. Reception of the concept (study). The supplier of vacuum-formed shapes receives the customer's concept and studies it. The supplier must have extensive knowledge to properly analyze the technical requirements, evaluate the project's feasibility, and determine the best way to carry it out.
  3. Support. Once the supplier has studied the concept, they will work with the customer to develop a final configuration that meets all technical requirements. This may involve making suggestions, modifications, or recommendations to optimize manufacturing. The supplier and the customer will communicate actively throughout the design process to ensure they are aligned on the requirements and expectations.
  4. Advice. Advice is provided to the client in terms of materials, manufacturing techniques, and possible improvements. The objective is to take advantage of experience and knowledge to guarantee the quality and optimal performance of the final product.
  5. Manufacturing engineering. Manufacturing engineering is a critical step in the production of vacuum-formed shapes. It involves designing and manufacturing tooling and drying trays that ensure the precision of the final product. This includes the use of specialized parametric modeling software and state-of-the-art manufacturing equipment.
