What is Metal Injection Molding?
Metal Injection Molding (MIM) is a development of the traditional powder metallurgy (PM) and plastic injection molding process. MIM process is an advanced powder processing technique because of net shaping with shape complexity at low processing energy and 100 % material utilization.
The MIM Process
• Mixing – Blend fine metal powders with proprietary ingredients to create viscous feedstock.
• Molding – Form complex shapes using standard injection molding tools and equipment.
• Debinding – Prepare molded components for high temperature sintering.
• Sintering – Subject components to temperatures up to 1600°C to achieve up to 99% densification.
• Finishing – Add standard engineering detail as needed (e.g., plate, heat treat, black oxide).
MIM Materials:
• Stainless Steels
– 304L, 316 L, 17-4 PH, 420, 440
• Low Alloy Steel
– 4605, 4105, 2200
• Titanium Alloys
–Ti, Ti-6Al-4V
• Soft Magnetic Alloys
– Fe-Si, Fe-Ni, Fe-Co
• Tungsten Alloys
– 95%W-Ni-Fe, 97%W-Ni-Fe
MIM Application:
Automotive Systems - Steering Columns (actuators, ignition lock components), Sun Roofs (stop cams), Seating Mechanisms, Solenoids, Fuel Injectors
Orthodontics – Brackets, Buccal Tubes
Medical and Dental Instruments – Endoscopic Surgical Instruments
Firearm Components – Triggers, Sights, Safeties, Seer Blocks
Ordnance – Guidance Fins
Hardware and Lock Parts – Lock Cylinders, Bolts, and Sidebars
Computers and Electronics – Disk Drive Components
Electrical – Connectors, Switches
MIM Advantage:
The metal injection molding (MIM) process offers the following advantages:
Cost-effective manufacture of high volume complex parts
Reduced production time compared with investment casting
Net-shape manufacture with minimal material waste (runners, sprues recycable in-house): more significant as materials costs rise
Mechanical properties superior to castings and other PM parts reflecting fine particle size and high sintered density
Properties equivalent to wrought alloys
Wide range of pre-alloys and master alloys available
Minimum of finishing operations
