Load cell LSMSB-*

A specialized digital conversion module of 8-channels inputs that measures the mold cavity pressure of the injection molding machine.The pressure value is watched on the condition set beforehand, and the result is output as an alarm signal. Forward the pressure value waveform converted into the analog voltage to the molding machine.

【Features】
・The mold cavity pressure can be measured, managed and recorded easily with low cost. Up to now, that was a Black Box though the pressure was an important parameter in a quality of molded products.
・The actual measuring waveform of the pressure when the resin is filled into the forming die is useful to manage the quality of molded product.
・Shorten the time for optimizing the molding condition by an experimental trial and for matching the condition in mass production factory.
・The product quality in mass production can be determined by setting the condition of the determination based on the pressure waveform of non-defective product.

Features

・Compact load cell with φ7mm×height 5mm (5kgf/10kgf/20kgf/50kgf), Φ10mm×height 5.5mm(100kgf),φ10mm×height 6mm(200kgf),φ12mm×height 8mm(500kgf),φ15mm×height 9.5mm(1tonf),φ20mm×height 16mm(3tonf)
・Achieve the small size, high accuracy and the low price by in-house strain gage technology.
・Excellent in noise-proof by 4-gage method, and do not receive the temperature effect easily even if the sensor is built into the metal mold with high temperature.
・A free metal mold design that doesn’t receive the restriction of the ejector pin diameter can be designed because of the method set up in the ejector pin bottom used.
