《YIZUMI Customer Magazine Die Casting》：After more than a year's production of UN1250MGII machines, how has the German company HETTICH been using it so far?
Philipp Ochotta：
Because of an increased demand for complex-shaped light weighted parts by their own customers, HETTICH used the UN1250MGII machine for producing several mini series of prototypes. By now, the machine shows a stable and reliable production behavior. Despite that, HETTICH provided us a few minor suggestions during the process. However, through continuous and good communication between HETTICH and our employees in Germany and China, we have been able to eliminate almost all difficulties to date.

《YIZUMI Customer Magazine Die Casting》：
What kind of products does UN1250MGII produce for HETTICH?
Philipp Ochotta：
For reasons of confidentiality, I must not be too specific at this point. But, as much as I can reveal, products cover automotive and urban mobility (electric scooter). These include components with large aspect ratios, low wall thicknesses components with very complex and filigree geometries, as well as components that place high demands on dimensional accuracy. This is where the strengths of Thixomolding become particularly apparent, as designs can be realized that are not possible with conventional die casting.

《YIZUMI Customer Magazine Die Casting》：Does HETTICH have new requirements on UN1250MGII machines so far? And how does YIZUMI satisfy their new needs?
Philipp Ochotta：
The complex parts that HETTICH is producing are setting high demands on the gating systems and the shot weights to be realized. I’m very happy to announce that HETTICH is using our YIZUMI hot drop technology to equip nearly all of their molds with a hot sprue system. The hot sprue is directly installed into the mold and works as an extension of the machine nozzle. The semi-solid material can be directly injected into the parting plane of the cavity. This not only reduces the shot weight dramatically due to a smaller gating system, but also improves the filling behaviour and the overall part quality.
Besides that, HETTICH requests high standards on operator’s safety and user friendliness on all of their machinery and equipment. Thanks to their valuable suggestions, we have already been able to significantly improve the control system software. We were also able to modify safety equipment from our YIZUMI injection molding machines, like e.g. a safety footboard for the mold area of the DP series, so it can be used in the rough foundry environment as well. This example shows one of the big advantages of YIZUMI and its diverse machine portfolio: We can take already proven technologies from a machine series and use them in novel application scenarios.
