Case Study # 2 - Industrial: Sewing Machine Thread Looper
Case Studies: Engineering and Contract Manufacturing Sales, Moore Technology, Indianapolis, Indiana, Serving Industry Since 1990
This case
study illustrates how Moore Technology can help reduce the number
of processes and secondary operations needed to produce complex,
polished, de-burred parts with state-of-the-art processes like Metal Injection
Molding (MIM) and Electrical Discharge Machining (EDM).
Application: Commercial sewing machine thread looper
- Wear
surfaces induction hardened to HRC 55MIN (microhardness)
- Zinc plated for corrosion protection
Problem: Current version of stitching machine required numerous
machining and polishing operations to produce an acceptable finished
part from an investment cast blank.
- Part had small diameter
holes of .043 (+/- .005) and .31 (+/- .002 ) which entered and exited
through a .047(+/- .005) wide slot to form a thread path which must
be completely free of burrs
- Costs were too high to polish, buff and de-burr parts
Our Solution: We developed a
better way. Previously machined features would be incorporated
into a single MIM process.
Additionally:
- Company logo was added to part for a small one time tool charge
- EDM was used to produce burr free holes with excellent finishes for
stitching thread
- We helped our customer identify and specify
materials, heat treat and plating options to optimize part performance while
holding down costs
Results: Utilization of the MIM process
enabled us to:
- Significantly reduce secondary machining operations
- Virtually eliminate polishing operations
- Improve product consistency and quality
- Reduce the cost per part
