Title: Innovations of Masashi Kato in Metal Shaping Technology

Introduction

Masashi Kato is a prominent inventor based in Hiroshima, Japan. He has made significant contributions to the field of metal shaping technology, holding a total of 4 patents. His work focuses on improving processes in injection molding, particularly for metallic materials.

Latest Patents

Kato's latest patents include a groundbreaking process for producing shaped parts of metals. This innovative method involves feeding a metallic feed, initially in a solid state, into a cylinder barrel of an injection molding machine. The metallic feed is melted by applying heat from outside the cylinder barrel and from frictional and shearing forces generated by the rotation of a screw housed within the cylinder barrel. The design of the cylinder barrel and screw defines at least a feed zone, a compression zone, and an accumulating zone. After melting and passing through these zones, the metallic feed is injected into a die to form a shaped part. The temperature of the metallic feed is carefully controlled to remain above the liquidus during the injection process.

Another notable patent by Kato is a method and apparatus for controlling screw positions in injection molding. This method involves detecting the position of a screw immediately before the start of injection, comparing this value with a predetermined plasticizing/measurement position, and adjusting the screw stroke accordingly. This ensures consistent performance for every shot of the injection molding machine.
