Create Precision Magnesium Parts with Thixomolding

Thixomolding—also known as magnesium injection molding or MAG—is a single-step, semi-solid molding process in which chips of magnesium alloy are fed into a heated screw and barrel, then thermally and mechanically processed into a semi-solid state and injected directly into a tool cavity. This versatile injection molding process uses magnesium alloys as the raw material to create parts with complex geometries—making MAG an increasingly popular option for key industries including medical components, electronics, automotive, defense, consumer products, sports equipment, handheld devices and more.

Phillips-Medisize provides expert support with specialized injection molding techniques like thixomolding, which accommodates large production volumes and minimizes secondary operations such as machining. Molded parts can then be conversion-coated and painted to meet your finished requirements. Thixomolding allows you to cost-effectively manufacture customized components and complex geometries with: 

  • High strength-to-weight ratio 
  • 75% lighter than steel 
  • 33% lighter than aluminum 
  • Strength and stiffness 2 times greater than 30% glass-filled plastics 
  • Good heat transfer characteristics (less than Al but better than plastics) 
  • Inherent EMI/RFI properties 
  • Non-magnetic properties 
  • Easier recyclability than plastic 
  • Excellent damping capacity 
  • Good corrosion control via conversion coatings and understanding of the application 
  • First priority: galvanic corrosion protection 
  • Easy machinability
