In injection molding and extrusion molding, a variety of plastic raw materials are required for precise proportioning (raw materials, recycled materials, masterbatch, additives, etc.). During the manufacturing process, if the ratio of raw materials is inaccurate, the performance of the final product will not meet the design requirements, such as insufficient strength, poor toughness, insufficient heat resistance, etc. Therefore, accurate raw material ratio is the key to ensuring stable product quality.
Three major issues in the ratio of plastic raw materials
1: Manual mixing error is large and product quality is low.
The ratio of plastic raw materials needs to control parameters such as mixing time, mixing speed, and mixing temperature to ensure that the raw materials are fully mixed. Manual mixing of raw materials will be affected by the operator’s subjective factors, such as fatigue, emotion and other factors, which may lead to mixing errors. This will result in uneven mixing of the raw materials, and the performance of the final product will also be affected.
2: Waste of raw materials and increased costs.
Manual batching requires a lot of manpower and time, and inaccurate batching will waste raw materials, lead to an increase in production costs, and also increase production time and costs.
3: Low production efficiency.
Artificial plastic raw materials ratio errors are large, and inaccurate control of the ratio of raw material ratios will lead to poor plastic quality, such as bubbles, cracks, deformation and other problems on the plastic surface. Unreasonable ratio of raw materials may lead to low production efficiency.
Smart weighing and mixing
With the rapid development of the plastics industry, it is difficult to ensure product quality and work efficiency by simply relying on manual weighing, mixing and feeding of raw materials in the plastic extrusion process. Nowadays, industrial technology is advancing rapidly. Automatic gravimetric batch blender can realize production automation and replace traditional mixers to prevent errors in the manual batching process and waste of raw materials.
Features of gravimetric mixer
1.High degree of automation
The plastic raw materials gravimetric mixer adopts advanced electronic weighing instruments and PLC control systems, and is equipped with a material shortage alarm system, which can realize fully automated operation and greatly improve work efficiency and production efficiency.
2.High mixing accuracy, error within 0.05%
With advanced batching technology, the machine has advanced deviation calibration function, which can identify subtle deviations and calibrate them, and can accurately weigh various raw materials, thus ensuring the stability and consistency of the quality of the mixed finished product.
3.Simple and convenient operation
The plastic gravimetric blender is simple to operate. You only need to set the required mixing ratio, mixing time and other parameters, and you can start automatic mixing. The operator does not need professional skills and is easy to learn and operate.
4.Modular and removable, easy to install
Beautiful appearance and compact structure: The gravimetric mixer has a beautiful overall appearance, compact structure, small footprint, and is easy to install and move.
5.Recipe storage confidentiality function
It can store up to 50 recipes, which can be managed at different levels. It has password protection function to effectively prevent recipe leakage.
Today’s plastics processing industry is facing increasingly severe competition and continuous market changes, and how to ensure product quality and market competitiveness. Weighing and measurement control technology just meets the growing needs of injection molding, extrusion, film blowing, etc. in the plastics industry.
