Essentially, materials such as magnesium are effectively alloyed to create a thixotropic material. This alloy can be shear heated like a polymer to create a semi-solid slurry which can be injection molded. The tonnage is approximately 1 ton per cm^2. This process does require specialized equipment and should not be done on a standard injection molding machine.

Like injection molding, the parts should have good design features such as draft angles and fillets. The final part has approximately 0.5% shrinkage.
