Our Production
Production process
IAC works with castings from initial concept to finished product. We work with our customers to develop prototypes, and then move on to series production.
We have a high degree of processing through machining, surface treatment and assembly.
Melting
To ensure the highest possible quality in our products, we use a carefully controlled purification process. By treating the melt with Nitral C19 tablets, impurities are effectively removed — they rise to the surface and can be skimmed off before the casting process begins.
This method helps keep our furnaces in optimal condition and ensures a consistent and clean aluminum melt. The result is products of higher quality and fewer defects — just as our customers expect.
High presssure die-casting
IAC has a flexible production facility for high-pressure die casting. Our machinery includes die casting machines with a clamping force ranging from 200 to 2,750 tons and a casting weight spanning from 0.01 to 20 kilograms. The total melting capacity exceeds 8,500 kilograms per hour, enabling us to handle both large production runs and complex components with high precision.
For further processing, we have CNC machining, which enables us to deliver fully machined components directly to the customer. We also offer surface treatment, where powder coating is carried out both in-house and in collaboration with carefully selected subcontractors.
The result is an efficient end-to-end solution – from melt to finished part – with a focus on quality, precision and customer needs.
Gravity die casting
IAC also carries out gravity die casting at our foundry in Estonia. Casting weights vary in size, enabling flexible production tailored to different components.
After casting, heat treatment is carried out with a capacity of several thousand kilograms per hour, ensuring that the materials achieve the desired mechanical properties.
For the subsequent machining, CNC technology is used, ensuring high precision and efficiency in manufacturing. IAC also has its own production of sand cores. The cores can be manufactured in varying sizes, enabling adaptation to a wide range of cast products.
Heat treatment
För att säkerställa att våra produkter får rätt styrka och hållbarhet genomgår delar av vårt aluminiumgjutgods en värmebehandling. Processen används för att förbättra materialets mekaniska egenskaper – till exempel att göra det starkare, mer formstabilt och tåligt mot belastning.
To ensure that our products achieve the right strength and durability, part of our aluminum castings undergo heat treatment. The process is used to improve the mechanical properties of the material – for example, making it stronger, more dimensionally stable and resistant to load.
The result is aluminium components of high quality, long service life and reliable properties – something that is valued by our customers in sectors such as the automotive and engineering industries.
Processing
After casting, and where applicable heat treatment, we offer advanced machining of castings entirely in accordance with the customer’s wishes and requirements.
Our machinery includes a large number of multi-operation machines – horizontal, vertical and 5-axis – as well as CNC-controlled lathes. This capacity enables us to deliver high precision, flexibility and quality at every stage of the machining process.
Installation
We offer assembly of casting components based on the customer’s needs – from individual parts to finished products. Our assembly process is flexible and is adapted to ensure high quality, precision and efficiency at every stage.
Powder coating
Our powder coating process takes place in our own facility. Here we are able to ensure high and consistent quality throughout the entire process – from pre-treatment to finished surface. The pre-treatment is specifically optimised for aluminium materials.
The powder is applied automatically with high precision, followed by a controlled curing process. Through continuous monitoring at every stage, we can guarantee that the result meets both our own and the customer’s requirements.
The powder coating facility is located at our foundry in Hultsfred.
