*Client

Motor Parts Manufacturer for Washing Machine in Korea

*Product Specification

Part Name Motor Case
Material SECC (JIS)
Thickness 1.6mm
Applied Press 400tf Transfer Press, Model TMX-400

Assignment

  • The accuracy of Φ26;0.016/0mm at bearing inserting point was difficult to secure by press forming and it is typically performed by cutting.
  • The variation of raw material thickness also affected the press process.

Resolution and Result

  • Applied press forming to manufacture parts that was previously processed by the cutting operation and achieved the same precision level.
  • Compared with the other raw material supply made in Japan, the issue of inconsistency on the raw material thickness was resolved.
  • As a result, maintained the level of accuracy, increased the productivity drastically, and cut down 20% of the total cost.

Replace the current joining process of two parts with one by press forming Apply reverse redrawing process and fully automate the operation!

*Client

Manufacturer for Food Aluminum Can in Japan

*Product Specification

Part Name Aluminum Can for Food
Material Aluminum
Thickness 0.23mm
Applied Press 200tf & 300tf Tandem Transfer Press

Assignment

  • Joining two parts technology was used.
  • There was no other way to reduce production cost further under the existing price competition.
  • Requested to provide a workable solution to integrate two molding processes into one process.

Resolution and Rresult

  • Built a special equipment to integrate and fully automate two molding processes into one process from the original two jointed parts.
  • Installed dual transfer unit in the press machines to double its productivity.
  • As a result, improved the productivity by four times and cut down the manufacturing cost by 50%.
