In the production process of injection molding products, color difference is a common and troublesome problem. Color difference not only affects the appearance quality of the product, but also directly affects the brand image and market competitiveness. In order to effectively solve this problem, the application of volumetric doser becomes crucial.
The root cause of color difference problem
The color difference is often caused by multiple factors, such as quality fluctuations of raw materials, uneven dispersion of masterbatch, instability of process parameters and aging of equipment. Among them, whether the amount of masterbatch added is accurate directly affects the color stability of the final product.
The traditional manual method of adding masterbatch not only has the problems of large error and poor repeatability, but is also easily affected by the experience of the operator, making it difficult to ensure the color consistency between production batches.
How does the volumetric doser solve the color difference problem
The volumetric doser ensures the color consistency of each batch of products by accurately controlling the amount of masterbatch added. The working principle of the masterbatch is to automatically add the set masterbatch ratio to the raw material through a precise weighing and metering system.
Precise control: The volumetric doser monitors and adjusts the amount of masterbatch added in real time through precise sensors and control systems, ensuring that each masterbatch is accurately mixed into the plastic raw materials, effectively avoiding errors caused by manual operation.
Improve production efficiency: The volumetric doser can work continuously and stably, reducing the frequency and operation time of human intervention, and improving the efficiency of the entire production line.
Reduce scrap rate: Due to the high-precision control of the volumetric doser, the color difference problem of the product has been significantly improved, thereby greatly reducing the scrap rate and improving the production qualification rate.
Case analysis: Application of volumetric doser in actual production
Before using the volumetric doser, a well-known plastic products company had serious color difference problems in its products and received constant customer complaints. After the company introduced the volumetric doser, the color consistency of the product was significantly improved through precise masterbatch addition, and customer satisfaction was also greatly improved.
In addition, the volumetric doser also helped the company save the use of masterbatch and reduce production costs. While ensuring product quality, the company’s overall production efficiency has also been improved.
Summary
Although the color difference problem is complex and diverse, the use of advanced volumetric doser can greatly reduce the occurrence of color difference and improve product quality. For manufacturers in the injection molding industry, choosing a suitable volumetric doser is not only an effective way to improve product competitiveness, but also the key to ensuring customer satisfaction. In the future, with the continuous advancement of technology, the application of volumetric doser in injection molding production will become more popular, bringing more possibilities for the development of the industry.
