石塚機械設計事務所 List of Products and Services

The "Gravimetric Controller" is a controller for managing weight-based supply systems. It measures the readings from the load cell platform scale (PFW-15K/60K/100K) while controlling the screw rotation of the feeder to perform quantitative feeding (feedback control). Operation is conducted via an LCD touch panel. By setting any desired supply amount, the controller automatically adjusts the supply quantity. 【Features】 ■ Operation modes include automatic operation, manual operation, and test feed. ■ Data recording function for supply quantity to monitor supply status. ■ By setting any desired supply quantity, it automatically adjusts the supply amount. ■ Notifies system abnormalities through a three-color signal light and buzzer output. *For more details, please refer to the PDF document or feel free to contact us.

The AS983 is an automatic release agent spraying machine designed to automate the spraying of release agents in plastic molding environments. The digital counter allows for the selection of spraying every 1 to 99 molding shots, and the digital delay and spray timer can be accurately set from 0.1 seconds to 9.9 seconds. Additionally, the spray output, empty can buzzer, and electromagnetic pump output utilize SSR (solid-state relay), eliminating contact wear and significantly improving durability. 【Features】 ■ Automatically alerts with a buzzer when the release agent canister is empty ■ Achieves the desired effect with a small amount of spray without wetting the molded products ■ Completes the required spraying in a short time ■ Maintains consistent molding cycles and injection counts, making quality control easier *For more details, please download the PDF or feel free to contact us.
