Title: Hiroshi Kitamura: Innovator in Die Casting Technology

Introduction

Hiroshi Kitamura is a notable inventor based in Zama, Japan. He has made significant contributions to the field of die casting technology, holding a total of 3 patents. His innovative methods have enhanced the quality and efficiency of die-casting processes.

Latest Patents

Hiroshi Kitamura's latest patents include a method for controlling injection in a die casting machine and apparatus. This method allows for the production of high-quality die-casting products without fins, even during high-speed casting or when using low-precision dies. The technology features a pressurizing controllable valve that is flow adjustable. The main spool is designed with a two-way valve that includes a check-valve function and a position detector for servo control. This setup enables the hydraulic fluid flow to be adjusted rather than simply switched on and off, thus preventing the production of fins and ensuring high-quality outputs.

Another patent focuses on a method and apparatus for controlling injection in a die-casting machine. This apparatus includes an open-shut valve for managing the hydraulic channel through which hydraulic fluid is discharged from a boost cylinder device. By regulating the hydraulic channel with control valves, the boost cylinder device can apply additional pressure to the injecting piston, assisting the injection process and preventing inappropriate changes in injection speed. This innovation ensures a smooth and efficient die-casting operation.
