Latest Patents

One of his latest patents is a mold protection method for a mold clamping apparatus. This method involves setting a predetermined mold protection zone where an anomaly, such as the presence of a foreign object, can be detected based on changes in physical quantities. The process includes establishing a reference position for the movable platen, setting the end position of the mold protection zone, and correcting this position based on deviations during production operations. Another significant patent is a method for preventing impact pressure in injection molding machines. This innovation involves supplying gas into an oil transfer line during the molding cycle to prevent impact pressure that could occur at the start of the injection step. This ensures that the oil transfer line is nearly empty of oil, allowing for swift flow of pressure oil during injection.
