Ideal for the manufacturing and coating applications of special films! Achieves uniform and flawless film production with overwhelming discharge precision!
Film products are directly affected by the performance of the pumps supplying the liquid agents, which results in differences in quality. By using our pulsation-free, metering pumps, high-precision film manufacturing and coating become possible. 【Main Benefits of Implementation】 ● Capable of delivering a flow rate deviation of ±0.1% or less, resulting in uniform material and film thickness. ● The discharge amount is proportional to the rotation speed of the drive motor, allowing for easy and accurate control of the filling amount. 【Examples of Applications】 ● Manufacturing of Film Bases In the liquid agent injection process during film base manufacturing, our pulsation-free metering pumps are used for filling auxiliary liquids and liquid gases into the extruder. It is crucial to minimize the pulsation in the supply of fillers, and additionally, our pulsation-free metering pumps are essential as they are less affected by pressure fluctuations and can fill from any position. ● Coating on Film Bases Our pulsation-free metering pumps have been used for coating applications in photographic film for some time, and now, leveraging the expertise gained, they are actively used in various continuous coating applications such as dip coating and die coating.

Applications/Examples of results
● Line mixing and emulsification (emulsification/synthesis) Due to its non-pulsating nature and excellent metering capabilities, it can maintain a constant flow rate proportional to the pump speed, enabling emulsification, mixing, and synthesis on the line, which were previously reliant on conventional batch methods. ● Proportional injection of catalysts and paints into extruders Because it is non-pulsating and resistant to load fluctuations, it does not experience changes in discharge flow rate due to pressure fluctuations like gear pumps do, allowing for a stable injection of catalysts and paints into the extruder. ● Precision coating Thanks to non-pulsating metering, when used for coating, it can achieve a consistently uniform thickness. Additionally, its structure minimizes cavitation, preventing bubbles from mixing into the coated surface and ensuring perfect coating. It is also completely unaffected by slight changes in suction head or pressure variations due to filter clogging. ● Precision spraying ● Spray drying ● Combustion testing machine With a non-pulsating and metered flow, the particle size sprayed from the nozzle remains consistent, improving the quality of the product.
