It is a model that automates a part of the measurement.
By automatically performing a cylinder cleaning (the gauze used for cleaning is manual set) from the weight of the weight load and preheating to the exhaust of the residual test fee after the measurement, it is possible to secure and stable.
Resin filling and cylinder cleaning are performed by the measurer while checking the resin, and the high temperature (up to 400 ° C), which is dangerous in terms of gauze heat -resistant temperature in automatic cleaning, is used.
Various options such as PC software (real -time data output), automatic sample cut equipment, automatic sampling recovery device, leakage prevention device (for high flow of flowing resin), A -method Automatic multiplication bottle (transmitting mass to the test machine and MFR is calculated automatically) will contribute to measurement and data management efficiency.
・ Equipped with an automatic measurement unit, a series of actions from the start of the measurement after the sample to the end of the measurement will be performed automatically.
・ Since the load on the test weight and the remaining samples are automatically performed, the loading of operators, improving safety, and reducing the work time.
・ Stable measurement is possible because the preheating condition (preheat time, piston retention position and holding time) can be set forth, so that the actual hot time until the measurement starts can be constant.
・ The furnace cleaning unit allows the furnace cylinder to be cleaned simply by setting the gauze.
Since thermoplastic resin can be mass -produced inexpensive, it is used for all products such as home appliances, automotive parts, and household goods, and is indispensable in our lives.
There are methods such as injection molding, extruding molding, and blow molding as a method of processing thermoplastic resin, but in any molding method, the liquidity of the molten resin is an important indicator.
Meltflate is widely used as an indicator of molten resin fluid, and is standardized in ISO, JIS, ASTM, and ASTM has slightly different terms and regulations for ISO and JIS, but the measurement principle is the same.
Generally, the larger the meltflow rate, the better the fluidity, and the smaller it is, the worse the liquidity. In addition, when the same type of resin is measured, the larger the value, the higher the molecular weight and the higher the molecular weight.
However, since the measurement is basically almost static, the shearing speed generated in the resin under measured is very small in terms of the shear speed at the time of injection molding, etc., and may not be correlated with the actual processing. Therefore, it is mainly used in quality control of materials.
