Injection molding machine is a common plastic machinery. For operators who use and purchase it, they should firstly understand the performance of a machine and what aspects to evaluate to choose a satisfactory machine. For different products, the machine has different pertinence. For instance, there are slight differences between Injection molding machine for plastic sprayer the machine for pipette tip. Next, we'll talk about what should we observe before selecting the machine.

Technical parameters of injection molding machine

Users can judge by vertical or horizontal comparison when purchasing injection molding machines. The so-called "vertical" means that the main technical parameters of the injection molding machine should meet the industry standards and be examined according to the industry standards. The so-called "transverse" is to compare the technical parameters of similar injection molding machines at home and abroad. Thus, this is a very careful and scientific work. The selection of the parameters of the injection molding machine are very complex. It is according to the material, shape, structure and application field and specific occasion of injection molding products; according to the structure, quality, accuracy, number of cavities, type of runner and its structure, shape and size of the die and in terms of the daily, monthly and annual production capacity and the degree of automation of the products. For example, the selection of injection molding machine for making injection molding machine for plastic sprayer and KIA Auto SPEED sensor must be different.  Besides, the 4000mAh mobile charger is also the finifshed products of injection molding devices.

Supplier of injection molding machine

It is best to choose a manufacturer with a service center near to you, because the structure of the injection molding machine is complex, it is inevitable that there will be problems, and fast after-sales service is very important then. When purchasing, do not blindly seek low prices. The prices of accessories on injection molding machines are very different between domestic and imported ones, so you’d better try to find out what brand of accessories the manufacturer uses. Of course, you can't see some accessories, such as oil seals and bearings, so the popularity and credibility of manufacturers are very important at this time. Here I highly recommend Ningbo Lisong Injection Molding Technology Co., Ltd, it is a leading manufacture of injection molding machine.

Model of injection molding machine

The two main parameters of injection molding machine are injection volume and clamping force. The product weight after first process should be less than 70% of the theoretical output of the machine to ensure the quality of the product. The required clamping force is calculated according to the projected area of the product. Besides, we need to pay special attention to whether the distance between columns, mold opening stroke and minimum mold thickness of the machine are suitable for the mold. there are many uses for injection molding, like china  PIR sensor and digital thermometer for home. 

Injection molding machine should be highly automatic, full-featured and high production efficiency

Modern injection molding machines can realize manual, semi-automatic and full-automatic operation. As long as the mold design is reasonable, they can realize full-automatic operation from injection mold filling to product ejection and falling, and can also be equipped with manipulator to realize unmanned operation. The function of core pulling and inserting, hydraulic nozzle control and rapid heating channel probe can be programmed into the automatic program in the injection molding cycle for automatic circulation. High production efficiency is mainly reflected in the short molding cycle of each molded product under normal injection molding process conditions. This reflects the comprehensive performance index of the mechanical, electrical and hydraulic system of an injection molding machine.  Therefore, high-quality hydraulic and electronic components and precise manufacturing technology must be used to improve the sensitivity and repeatability of the injection molding machine system, which is a reliable guarantee for the efficient work of the injection molding system. 

Energy saving and environmentally friendly

Energy saving and environmentally friendly are the key points of modern injection molding machine. Energy saving mainly reflects the water-saving and power-saving ability of the injection molding machine compared with similar machines when the heating system (electromagnetic heating), power drive system (frequency converter, server, etc.) and heat dissipation system meet the normal process conditions. The theme of "environmental protection" should be fully considered in the design of modern injection molding machine. The injection molding machine shall prevent hydraulic oil leakage or excessive noise and work quietly. In addition, the material of  injection molding machine itself should also be more environmentally friendly. Nowadays, many industries has started to emphasis on environmentally friendly such as RPET backpack or conference chair.

Convenient for machine maintenance and overhaul

The installation position of various machines such as mechanical, hydraulic, electronic and electrical components shall be conducive to the maintenance and overhaul of the machine. At the same time, the universality and standardization of the injection molding machine are also very important to users. 

In conclusion

Injection molding machine is a great invention for finished production on a massive scale. It can produce almost everything related to plastic, such as injection molding machine for plastic sprayer. Choosing a suitable machine for you is very important. If you’re going to purchase one injection molding machine, Ningbo Lisong Injection Molding Technology Co., Ltd is a great option.
