Injection molding Machine Productivity Evaluation Guide: How to choose the right equipment to increase production efficiency

With the continuous development of the manufacturing industry, injection molding technology has become one of the important processes for the production of various plastic products. Injection molding machine as the core equipment to achieve this process, its production capacity directly affects the production efficiency and product quality of enterprises. Therefore, the correct evaluation of the production capacity of the injection molding machine and the selection of the right equipment is crucial to improve the competitiveness of the enterprise. The following details how to evaluate the production capacity of the injection molding machine and how to choose the right equipment.

1、 The importance of injection molding machine production capacity evaluation

The production capacity evaluation of injection molding machine refers to the comprehensive analysis and evaluation of the production capacity of injection molding machine, including the performance, stability, efficiency and other aspects of the machine. Through capacity assessment, enterprises can understand the operation status of existing equipment, find potential problems and room for improvement, so as to formulate reasonable production plans and equipment renewal strategies. In addition, capacity evaluation can also help enterprises make more informed decisions when choosing new equipment, avoiding the waste of resources and production efficiency caused by improper equipment selection.

2、The injection molding machine production capacity evaluation method

【1】Equipment performance evaluation

Equipment performance evaluation is the basis of evaluating the production capacity of injection molding machine. It mainly includes the following aspects:

(1) Injection capacity: Injection capacity refers to the maximum amount of plastic that the injection molding machine can inject into the mold in a unit time, usually expressed in grams/second (g/s) or ounces/hour (oz/h). The greater the injection capacity, the stronger the production capacity of the injection molding machine.

(2) clamping force: clamping force refers to the maximum force that the injection molding machine can apply to the mold during the clamping process, usually expressed in tons (t). The greater the clamping force, the larger the size of the product produced by the injection molding machine, or can withstand higher injection pressure.

(3) Rate of fire: Rate of fire refers to the speed of the screw advance in the injection molding machine during the injection process, usually expressed in millimeters/second (mm/s). The faster the rate of fire, the faster the response speed of the injection molding machine, which can shorten the production cycle.

(4) System stability: System stability refers to the degree to which the injection molding machine maintains stable performance during long-term operation. A stable system can reduce the probability of failure and improve production efficiency.

【2】Equipment efficiency evaluation

Equipment efficiency evaluation is the key to evaluate the production capacity of injection molding machine. It mainly includes the following aspects:

(1) Production efficiency: Production efficiency refers to the number of production tasks completed by the injection molding machine in a unit time, usually expressed in pieces/hour (pcs/h). The higher the production efficiency, the greater the production capacity of the injection molding machine.

(2) Energy consumption: Energy consumption refers to the amount of energy such as electric energy and water energy consumed by the injection molding machine in the production process. The lower the energy consumption, the lower the operating cost of the injection molding machine.

(3) Maintenance cost: Maintenance cost refers to the cost of maintenance work needed to be carried out during the use of the injection molding machine. The lower the maintenance cost, the longer the service life of the injection molding machine.

3、How to choose the right injection molding machine equipment

（1)Select the right model according to the product requirements

Different products have different requirements for injection molding machines, so it is necessary to choose the right model according to the characteristics of the product when selecting the injection molding machine. For example, for large thin-walled products, an injection molding machine with high injection speed and high clamping force can be selected; For precision small products, you can choose an injection molding machine with a high-precision control system and a stable rate of fire.

(2)Consider the scalability of the device

When choosing an injection molding machine, it is also necessary to consider the expansion of the equipment. As the market demand changes and the size of the enterprise increases, the enterprise may need to add new production lines or replace more efficient equipment. Therefore, when choosing an injection molding machine, priority should be given to those with good scalability in order to upgrade in the future.

(3)Pay attention to the energy consumption and environmental performance of the equipment

When choosing an injection molding machine, you should also pay attention to the energy consumption and environmental performance of the equipment. Equipment with low energy consumption can reduce the operating costs of enterprises, while equipment with good environmental performance can help reduce the impact on the environment. Therefore, when choosing an injection molding machine, priority should be given to those equipment with energy-saving and environmental protection characteristics.

4、 Conclusion

In short, the production capacity evaluation and equipment selection of injection molding machines is a complex and important process. Through the comprehensive evaluation of equipment performance, efficiency and other aspects, enterprises can understand the operation status of existing equipment, find potential problems and room for improvement, so as to formulate a reasonable production plan and equipment update strategy.
