In the process of plastic coloring granulation production, waste problems often plague many companies. Reducing waste can not only improve production efficiency, but also reduce production costs. The following are five key points that need special attention to help you effectively reduce waste and improve production efficiency.
1. The masterbatch is directly produced and granulated without careful color testing
During the production process, the color testing of the masterbatch is very important. Masterbatch that has not been carefully tested directly enters the production line, which may cause problems such as uneven color and color difference, which will eventually affect product quality and increase the scrap rate. Therefore, before each batch of masterbatch is put into production, it is necessary to conduct strict color testing to ensure color consistency.
2. There are problems with the matching of masterbatch and resin
The compatibility between different types of resin and masterbatch varies greatly. If the masterbatch does not match the resin, it will cause uneven dispersion of the masterbatch, affecting the appearance and performance of the product. Therefore, when selecting the masterbatch, the matching with the resin should be fully considered to ensure that the masterbatch can be evenly dispersed in the resin to obtain the ideal coloring effect.
3. Inaccurate measurement during use, too much or too little masterbatch or pigment
The measurement accuracy of masterbatch directly affects the coloring effect and production cost. Inaccurate measurement will lead to too much or too little masterbatch or pigment, resulting in waste or unqualified products. Improving measurement accuracy can not only reduce waste, but also ensure product quality.
Causes and effects of inaccurate masterbatch measurement
There are several main reasons for inaccurate masterbatch measurement:
Equipment aging: Old equipment is prone to measurement errors.
Improper operation: Operator negligence or lack of experience can also lead to inaccurate measurement.
Raw material fluctuations: Changes in raw material properties such as density and particle size can also affect measurement accuracy.
Inaccurate measurement can lead to excessive or insufficient addition of masterbatch. Excessive masterbatch not only increases production costs, but may also affect product performance. Insufficient masterbatch will lead to uneven color and increased product unqualified rate.
4. Heat resistance of color powder
The heat resistance of color powder has an important influence on the coloring effect. In high temperature environments, some color powders may change color, decompose, etc., affecting the final color of the product. Therefore, when choosing color powder, its heat resistance should be fully considered to ensure that a stable coloring effect can be maintained during the production process.
5. Solutions to metering problems – using volumetric doser
In order to deal with the problem of inaccurate masterbatch metering, volumetric doser have become an indispensable part of the production process. Volumetric doser are a type of equipment specifically used for plastic coloring and granulation production, which can effectively improve the metering accuracy of masterbatch, reduce waste, and ensure product quality.
Advantages of volumetric doser
Accurate metering: volumetric doser use advanced metering technology to achieve high-precision masterbatch addition and avoid waste.
Automated operation: volumetric doser have a high degree of automation, which can reduce errors caused by human operation and improve production efficiency.
Real-time monitoring: volumetric doser are equipped with advanced monitoring systems that can monitor the production process in real time, detect and correct problems in a timely manner.
By reasonably selecting and using volumetric doser, enterprises can effectively improve production efficiency, reduce waste, and ensure product quality. Reducing waste is not only the key to improving corporate competitiveness, but also an important way to achieve sustainable development.
In the process of plastic coloring and granulation, attention should be paid to the color test of masterbatch, resin matching, metering accuracy, heat resistance of color powder and the use of volumetric doser, which can effectively reduce waste and improve production efficiency. By optimizing these links, enterprises can stand out in the fiercely competitive market and achieve higher economic and social benefits.
