Metal Injection Molding (MIM) Parts for Industrial and Tools

Product Description

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 **0 % 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 ***0°C to achieve up to *9% densification.
• Finishing Add standard engineering detail as needed (e.g., plate, heat treat, black oxide).
 
MIM Materials:
• Stainless Steels
**4L, **6 L, ***4 PH, **0, **0
• Low Alloy Steel
***5, ***5, ***0
• Titanium Alloys
Ti, Ti*6Al*4V
• Soft Magnetic Alloys
Fe-Si, Fe-Ni, Fe-Co
• Tungsten Alloys
*5%W-Ni-Fe, *7%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

• 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
