Ask Our Experts

MinebeaMitsumi developed a solution to improve the accuracy of molded parts using our expertise in strain gauge technology and injection molding processes. We use in-house injection molding equipment to produce molded components for use in our cooling fans, semiconductors and LED backlight products. In order to minimize costs and scrapped parts, we integrate load cells onto the ejector pin of the mold to measure cavity pressure. We can then optimize the cavity pressure to repeatedly produce ideal molded parts.

  • Mold cavity pressure can be measured, controlled and recorded easily with minimal cost
  • To manage quality of molded products, we analyze the pressure waveform when the forming die is filled with resin
  • Decrease time needed to optimize molding conditions and transfer to mass production
  • Ensure mass production quality using predetermined pressure settings from measurement tests
