Title: Yuki Matsui and Injection Molding Machine Innovations.

Introduction

Yuki Matsui is an inventor based in Chiba, Japan, whose patent work focuses on control technologies for injection molding machines. Matsui is associated with Sumitomo Heavy Industries, Ltd., and has 6 patents.

Latest Patents

Matsui’s recent patent work includes inventions titled “Control device of injection molding machine, injection molding machine, and method of controlling injection molding machine.” One disclosed technique manages the shear heating value of molding material. The control device independently adjusts heating-unit outputs across zones along the cylinder and compares the output in a selected zone during steady state, when the screw is stopped, with its output during molding, when the screw operates.

Another disclosed technique aims to suppress molding defects. It controls the increase in mold-clamping force after molding material reaches the parting surfaces of the stationary and movable molds, keeping that increase at or below a specified upper limit.

Career Highlights

Matsui’s patent portfolio reflects work on process control and molding quality. The described inventions address heating behavior within the cylinder and mold-clamping force during the molding cycle.

Collaborations

Matsui is associated with Sumitomo Heavy Industries, Ltd. His listed coworkers include Daigo Hotta and Yutaka Tsutsumi.

Conclusion

Yuki Matsui’s disclosed inventions focus on improving injection molding control by managing material heating and limiting mold-clamping force changes to help suppress defects.
