Utilization Method

In order to correctly measure the resin behavior inside the mold with pressure sensors, it is important to check the functinality of the pressure sensors. Here are 5 check items along with the mold condition, the target pressure sensor, the inspection method, etc. for each item.

In order to prevent the diversion of defective products caused by abnormal opening and closing of valve gate in a hot runner system, it is important to detect opening and closing abnormalities . We will introduce methods for automatically detecting valve gate opening and closing abnormalities using pressure sensors based on measurement examples.

This is a material that shows what you can read from a measured pressure waveform and explains the shape of the pressure waveform that varies depending on the shape of the molded item.

By setting the molding conditions in such a way that the waveform of the in-mold pressure overlaps with the waveform generated with good product quality (reference waveform), it is possible to reproduce the molding conditions for a good-quality product. This material explains its specific procedures.

This material explains the method of realizing “family mold” with different resin capacities by controlling the opening/closing timing of the valve gate with the pressure sensor and flow front detection sensor serving as a trigger.

This material explains the method of shortening the molding cycle by optimizing the V-P transfer timing and pressure retention time through comprehensive monitoring of the injection pressure on the molding machine side and the in-mold pressure.
