MIM Case Study - Lock Handle Components Application in Medication Carts

This case study discusses using MIM-316L material for lock handle components in medication carts, ensuring strength, resistance to disabling techniques, and corrosion protection. Sintering supports prevent distortion in the furnace, with added features for lightening parts.

Presentation Transcript

  1. MIM Case Study – Lock Handle Components Application: Medication Carts Functional Requirements: Enough strength to resist “low-tech” lock disabling techniques; non-magnetic

  2. MIM Case Study – Lock Handle Components Competing Technology: They were initially plastic, which did not have acceptable strength Material: MIM-316L

  3. MIM Case Study – Handle 1 1. Part weight 92 grams 2. Needs sintering supports to prevent distortion in the furnace 3. ID extended to cut down on cross-sectional thickness 4. Reasonable corrosion resistance

  4. MIM Case Study – Handle 2 1. Part weight 47 grams 2. “Free” extra features to “lighten” parts put in tool opening & closing directions 3. Reasonable corrosion resistance

  5. MIM Case Study – Handles Lightening features to get acceptable cross sectional thickness in MIM from the original plastic design

  6. MIM Case Study – Handles Lightening Feature On both parts coining is required to open interrupted diameter, which closes in sintering.

  7. MIM Case Study – Handles • Why MIM? • 316L Material more than adequate for strength & corrosion requirements • Geometry requires a molded part of some type (dies cast, investment cast) with the same feature detail as plastic injection molding • Yearly quantity low for MIM (<10,000/year) but engineering requirements were straightforward • Plastic to MIM conversion relatively rare. The key to this project working for both sides is the high end value of the medication cart.
