In July, at the China Die Casting 2025, Haitian unveiled a 7,000 ton magnesium Thixomolding machine with production readiness scheduled for later this year.
Haitian Metal now published on WeChat the first pictures of its HMG 7000, the world’s largest magnesium Thixomolding machine.

This machine is set to potentially achieve a record-breaking injection volume, though Haitian has yet to disclose further detailed specifications, I speculate that the injection weight could be likely above 35 kg.
To achieve this, Haitian will utilize a twin barrel configuration, like in plastic injection molding, two parallel barrels will generate the semi solid slurry and inject the material into the die.
This is very helpful to both increase the quantity of material you can process at once, shorten the flow length and keep the size of the screw smaller which can be a problem as the process scale up.
The drawback of the double injection system is the high cost, in fact the barrel and the screw are the most expensive part in a Thixomolding machine and doubling their number can be expensive.
Haitian released an illustrative example which shows the double injection can be performed in both synchronous and asynchronous configuration. The image below shows a tailgate on the left portion and a door on the right.
