In the production of plastic products, color masterbatch machines play a critical role in mixing color masterbatch with base plastic raw materials, and "proportioning accuracy" is a core indicator for evaluating the performance of color masterbatch machines. It directly affects the final color consistency, quality stability, and production cost control of plastic products.
Definition of Proportioning Accuracy
The "proportioning accuracy" of a color masterbatch machine refers to the closeness between the actual amount of color masterbatch added by the machine and the amount specified in the preset formula. This is typically expressed as a percentage error. For example, if the preset formula specifies a ratio of color masterbatch to base plastic raw materials as 1:100, but the actual proportion added by the machine is 1.01:100, the proportioning accuracy can be calculated as [(1.01 - 1) ÷ 1] × 100% = 1%. This means the actual amount of color masterbatch added exceeds the preset amount by 1%. Clearly, the smaller this error value, the higher the proportioning accuracy of the color masterbatch machine.
The "proportioning accuracy" of a color masterbatch machine is a key factor in measuring its performance and has significant implications for every stage of plastic product production. When selecting a color masterbatch machine, careful consideration should be given to whether its proportioning accuracy meets production requirements, ensuring the production of high-quality, low-cost, and color-consistent plastic products.
