Planetary-Carrier with Sun Gear
Benefit: Cost Saving, Increased Component Complexity
Main Forming Process: Metal Injection Moulding
End Use Sector: Consumer Goods
Material: Ferrous

Requirements

The customer was looking for a method to produce cost efficiently some 12 million high torque Planet-Carriers with Sun Gear for its volume requirement of planetary gear boxes, with an outer diameter of only 6.2mm. These Planetary-Gear Boxes are intended to be used in an opening and closing mechanism for cellular phones.

Benefits

The most cost effective manufacturing route for the high production volumes proved to be MicroMIM because instead of assembling 5 parts, MicroMIM can produce the Planet-Carrier with Sun Gear in one part. Cost savings compared to traditional production techniques, which are in the range of 40%, sealed the capture of this new application.

Component Specification

Density (g/cm3): 7.8
Surface Roughness: Better than Ra 0.4
Hardness (HV1): 450-550
