Introduction

Munekatsu Kamiya is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of injection apparatus technology. With a total of 3 patents to his name, his work focuses on improving the efficiency and quality of molded products.

Latest Patents

Kamiya's latest patents include advancements in injection apparatus design. One of his patents aims to reduce the axial dimension of an injection apparatus while facilitating the work of removing and inserting a screw. This innovation includes a heating cylinder, a screw, and a drive apparatus. The screw features a plasticizing portion with a body portion and a flight formed on its outer circumferential surface. An important aspect of this design is the index ε, which is derived from the relationship between the screw stroke S and the screw effective length L. This design ensures that even when the screw is shortened, resin can be melted satisfactorily, thereby reducing the axial dimension of the injection apparatus.

Another patent focuses on the screw and injection apparatus, aiming to melt a molding material uniformly and enhance the quality of molded products. In this design, the screw also comprises a plasticizing portion with a body portion and a flight. A groove-depth setting region is defined, where the ratio γ of groove depth to the diameter of pellets falls within a specific range. This innovative approach allows pellets to advance while rolling along the groove, preventing aggregation and the formation of a solid bed.
