What are the key points for purchasing an injection molding machine?

1. Purchase the technical parameters of the injection molding machine. When users choose injection molding machines, they can be judged by vertical or horizontal comparison. The so-called "longitudinal" means that the main technical parameters of the injection molding machine should meet industry standards and be reviewed according to industry standards. The so-called "horizontal" is to compare the technical parameters of similar injection molding machines at home and abroad. Therefore, this is a very careful scientific work. According to the material, shape, structure, and application fields and specific occasions of the injection molded product; according to the structure, quality, accuracy, number of cavities, runner type and structure, shape, and size of the mold; according to the day, month, and size of the product The annual production capacity and the degree of automation are used to select various parameters of the injection molding machine.
2. Choose the supplier of injection molding machine, because the structure of injection molding machine is complicated, problems will inevitably occur. Fast after-sales service is very important. Don't blindly ask for low prices when purchasing.
3. Choose the model of the injection molding machine. The two main parameters of the injection molding machine are injection volume and clamping force. In order to ensure the quality of processed products, the actual weight of a mold product should be within 70% of the theoretical injection volume of the machine. Calculate the required clamping force according to the projected area of ​​the product. And pay special attention to whether the distance between the columns of the machine, the mold opening stroke and the minimum mold thickness are suitable for the mold.
4. The man-machine dialogue ability and operability of the injection molding machine. The injection molding machine should make its operation and management more user-friendly, the operation should be convenient, the display should be clear, easy to understand, and clear at a glance. It has the function of parameter selection, product quality control, mold data storage and various parameters automatic reproduction function, which can quickly diagnose and eliminate faults, reduce material waste in the shortest time, and restore normal system operation.
