Die casted aluminum

Die casting is an efficient process with great accuracy and where tool investments are relatively low. This is the main reason why die casting is used in so many products from electronics, cars and household.

Advantages of die-cast aluminium

Die casting is an automated process with high capacity, high quality, small tolerances and a fine surface. In addition, excess material can be recycled in production.

Advantages of die-cast aluminum

Die casting is an automated process with high capacity, high quality, small tolerances and a fine surface. In addition, surplus material can be recycled back into the production.

Threads and areas high requirements for tolerances are machined after casting. The surface can be sandblasted, varnished, polished, chrome-plated etc.

Aluminum alloys

The most common aluminum quality we use is ADC12 (also known as A383) which is the most widely used material in die casting due to the combination of strength, durability, temperature resistance and good machining properties. Other alloys can also be used, but might give a slightly higher cost and require a higher MOQ.

The steps in the production of tooling for die-cast aluminum

PROCESS ENG2.png

As a basis for tool production, we need a 3D model of the component (STEP format) as well as 2D drawing with all details. Before we can start production of the tool, we will have a technical evaluation to clarify that all details.

Time schedule for die casting

The production of tooling will normally take 4-5 weeks. We deliver a few samples for approval. Once these have been approved, production can start. Normal production time is 4 weeks.

Facts about die casting

During die casting, liquid aluminum is filled into a steel tool and kept under pressure until it solidifies. The tool normally has a fixed and a movable part, where the movable part has ejector pins to eject the finished part. The tool may have movable slides, cores and sections for making holes and other designs in the casting. The working pressure is between a few MPa to approx. 150 MPa.

Aluminum becomes liquid at 660 ° C and behaves like water at this temperature. Therefore, great accuracy is required of the tooling.

Aluminum becomes flperforming at 660°C and is then roughly like water in its nature, and this requires great accuracy in the tool.

NormaWe estimate 5-6 weeks for the production of tools and 5-6 weeks for the production of profiles.

Quality control of cast aluminum with a microscope

Extruded profiles can be machined and hole patterns can be punched. Surface treatment is sandblasting or brushing, anodizing or painting.

 

For electrically conductive surfaces, use Surtec 650 RoHS compatible surface treatment. Text or logo is screen printed or laser engraved.

We are happy to fit details such as locks, screws and gaskets to deliver complete components.

 

Recycling of metal, both from own production but also from other products, reduces material costs, and is an environmental gain compared to, for example, plastic. When recycling aluminium, only a fraction of the energy is needed in relation to producing new material.
