What is Thixomolding?

Dynathixo is an advanced semi-solid metal casting technology developed by Dynacast together with TPI, blending traditional thixomolding with our cold chamber process. Thixomolding magnesium, also known as magnesium injection molding, has long been utilized in industries such as consumer electronics and e-bikes, and this innovative variation expands Dynacast's ability to provide high-performance magnesium solutions across a broader range of sectors. Dynathixo ensures superior quality and durability in magnesium components, offering a more efficient and innovative solution for industry leaders seeking optimized parts.

Thixomolding Vs. Dynathixo

Thixomolding uses solid chips that are compressed, heated, and mixed into a semisolid material before being injected into the die with the extruder.

Dynathixo combines Dynacast’s cold chamber process with a thixomolding extruder to mix solid chips into the pressure chamber, utilizing a cold chamber plunger and hydraulic system for a robust operation.

Inside the Dynathixo Process

The Dynathixo process involves feeding magnesium alloy chips into a heating chamber where they are mechanically processed and sheared by a rotating screw inside a barrel, transforming them from dendritic to globular state. The semisolid material is then injected into a preheated mold under high pressure, allowing for thinner walls, lower porosity.

Achieve Superior Quality with Dynathixo

Dynathixo helps prevent air entrapment, resulting in thinner walls, improved flow, and reduced wear on the sleeve and plunger.

A Sustainable Solution

The Dynathixo process optimizes energy efficiency by heating the material at a lower temperature and eliminates the need for inert gases, reducing both energy consumption and CO2 emissions. Additionally, since the Dynathixo machine only requires a nozzle tip, it achieves excellent shot weight ratio without the need for a tablet rest.
