Die Casting
A most important link in our processing chain is our fully-automated casting with the latest technology in both Shenzhen, China and Hultsfred, Sweden. With 20 years of working experience Hellmer Group can handle large volumes and manage short lead times.
In premises covering an area of 6 000 square metre we have a most experienced staff, on average 15 years within the Die Casting industry – We really know the business. Today we are proud suppliers of complex, high-precision aluminium castings to high-tech Industries. The machinery and equipment are based on the most up-to-date technology for the efficient handling of ingots. Fully automated Die Casting cells with continuous process control ensure a uniformly high quality, and our after-treatment unit includes throughput tumbling, washing and drying.

Central Melting
The molten metal is divided and transported from the central melting furnaces to the warming furnaces at the robot steered Die Casting cells. At present we manufacture castings in EN AB- 44300 and EN AB- 46000 alloys (other alloys also possible). The alloys are carefully verified frequently with our spectrograph.

Fully-automated Die Casting
Our Die Casting machines have a clamping force from 560 to 800 tonnes. The Die casting tools are connected to the central vacuum system, which provides the effective evacuation of air from the tools. The Die Casting process is monitored continuously for vacuum, press effect and temperature to ensure a uniform high quality.
Each Die Casting cell is served by a robot, which removes the cast components from the tools and places them on pallets in the pallet feeding system.

After-treatment
Basic after-treatment, such as the de-burring and tumbling of components, takes place directly in the Die Casting unit.
