Why Magnesium Injected Metal Molding?

Advantages Overview

G-Mag™ International magnesium injection metal molding provides you with consistent, complex-geometry net shape or near net shape components requiring no or very little finishing. This process is ideal for high-volume, high-strength, and/or high-performance applications:

Design/Engineering

  • Offers great design/engineering flexibility
  • Components can be produced in complex shapes previously possible only in plastic injection molding
  • Can address applications ranging from non-decorative structural to highly decorative, thin-wall construction
  • Can produce parts as thin as 0.5mm

Stiffness, Weight Savings

  • Delivers excellent stiffness and a high strength-to-weight ratio characteristics
  • Delivers optimum weight savings through parts consolidation design integration of several components into one unit

High Integrity, Accuracy, and Preferred Characteristics

  • Delivers high integrity components due to the smooth laminar filling of the mold, resulting in very little air entrapment and lower shrinkage porosity
  • Because of the fine grain structure and low porosity (98% to 99%) of finished components, they can also be coated with great results
  • Increased dimensional accuracy
  • Are made from corrosion-free alloys, with several value-added corrosion prevention coating options and final finishes also available
  • Provides inherent EMI/RFI shielding, so no additional plating is required
  • Offers significant heat transfer (heat sink) and electrical conductivity characteristics

Manufacturing

  • Maximum repeatability and precision
  • Delivers production rates that are similar to high pressure die casting or better
  • Injection speeds can be up to 6m per second, with fill times in milliseconds

Cost

  • The more complex the component, the more cost reduction you can realize
  • Potential for cost-savings and improved precision over typical die-cast processes
  • Can be up to 200 square inches (1290m) total projected area, with finished components of up to 6.6 lbs (3kg)
  • Eliminates most expensive and time-consuming secondary operations, such as machining steps and the need for adding reinforced inserts
  • Cost competitive due to high uptimes and high yields
