Injection moulding & Extrusion

Injection moulding and extrusion are high-volume manufacturing processes often used in the food & beverage industry. Injection moulding involves the production of products by injecting molten materials into a mould. The materials can be metals and glasses, but most commonly food-grade thermoplastic and thermosetting polymers. Injection moulding is used to produce a variety of products that handle food and drinks before you ingest them, such as bowls, bottles and caps, containers for storage and serving hot foods and beverages, packaging materials and much more.

The extrusion process also includes melting and forming materials but instead of a mould the material is pushed through (extruded) a die of the desired cross-section. This can result in many different profiles or as a film, and be used in countless applications.

Since both these processes include melting and forming material the process is very energy intensive and the heat load generated in the extrusion/injection moulding process is massive. This is also the reason it makes great sense to focus on this process when it comes to energy saving potential. Removing heat (i.e. process cooling) is important for the efficiency rate of the cooling system, and the ability to recover this heat for other purposes can be very useful for lowering OPEX costs.

Compressed air can also play an important role within the process, for example in different parts of the assembly process etc. In blow moulding (film extrusion), it plays a vital part in the production process. We can guide you through the compressed air demands and design an efficient and reliable solution suited for your needs.

The ventilation efficiency and the way the air is supplied to the production hall is also very important, both for the operational costs and for the specific process needs. Depending on the product the demand can be for low particle levels, dew point control (to avoid condensation) or temperature control. AirSon’s long experience within both the injection and extruding industries and MEP services means we can help you design and build an efficient and reliable production facility meeting your process needs.

Energy-efficient design

In a large production hall with many injection moulding machines, it’s imperative to have an understanding of the total heat load and convection flows. If there is a balance between treated fresh air and the convection air flow, it is relatively easy to create a work area around the machine with a comfortable temperature and low particle levels.

The main part of the electrical power used by the injection moulding machine is given off as heat. With a traditional mixing ventilation, this heat load must be balanced with an equally large amount of cooling. The energy needs for such systems, which are very common in the extrusion and moulding industry, have a major impact on the company’s bottom line. This is a typical challenge that we help our customers address.

Food & Beverage production

In all types of food production facilities, there are strict requirements on the cleanliness. Some areas and production steps are more critical than others. It can often be difficult to navigate between the different food regulations, for different processes and/or regions of the world. AirSon can help you safely navigate these requirements.

CIP & Sterilizing

In food processing facilities, the requirements for keeping the processing equipment and the containers clean, are always very rigid. The equipment needs to be cleaned (often with CIP, cleaning in place) and sterilized. At AirSon we have done a lot of projects in this area and have built strong know-how in the field of CIP and sterilizing.

R&D facilities

R&D facilities vary a lot in terms of design as well as in demands. It is crucial to have the best speaking partner when deciding on the level of cleanliness required for your specific process. AirSon can be the speaking partner you need.
