China is recognized by the United Nations as having the most complete industrial system in the world, and plastic machinery manufacturing is one of the fastest growing traditional industries. Injection molding machines play an important role in the rapid development of the plastics industry, both in terms of quantity and type. There are various injection molding machines with different models and applications in the market, so users are always confused about how to choose the perfect injection molding machine.
As a professional injection molding machine sales manager, to tell you how to choose the right injection molding machine in China.
1. Service
Do they show enough sincere attitude and provide enough excellent service? Some injection molding machine manufacturers in China can provide you with first-class pre-sales and after-sales services for injection molding machines at any time. China injection molding machine manufacturers will work with you to meet your needs.
Many Chinese injection molding machine suppliers are responsible and responsive to each and every customer. Local Chinese injection molding machine manufacturers have played an important role in helping overseas injection molding companies meet their budget and delivery needs.
You can transfer your capital to grow your business while maintaining high quality Chinese plastic injection molding and process standards.
2. Factory Environment
Machinery factories usually do not have a good environment, and very many of them may be dirty, but a good injection molding machine manufacturer's factory will definitely clean up in time, and yes the working production environment is very neat and tidy. The factory environment is a very good side reflection of the strength of an injection molding machine manufacturer.
3. Factory size
There are no doubt that there are too many injection molding machine factories in China, from small factories to big groups like Haitian. If you have a very limited budget, choose a small factory, of course, don't ask too much; medium-sized Chinese injection molding machine factories are a very suitable choice, their quality and price are very good, and often have their own R & D team, constantly follow up and update technology, and provide the necessary guarantees; if your requirements are very strict, no doubt, large injection molding machine manufacturers are the best choice, of course, the price Of course, they are more expensive.
4. Technical parameters of injection molding machine
When choosing an injection molding machine, you can make a vertical or horizontal comparison. A "vertical comparison" is to compare the main technical parameters of injection molding machines according to industry standards, and a "horizontal comparison" is to compare the technical parameters of the same type of domestic and foreign injection molding machines, both of which are needed for scientific work carefully.
The material, shape and structure of the injected product and its applicable fields and scenarios, the structure, quality and precision of the mold, the number of mold openings, the type, shape and size of the runner, as well as the daily, monthly and annual production capacity and the degree of product automation are all parameters to be considered when selecting an injection molding machine.

5. Safety of injection molding machine
The safety of human and machine depends on the reliability of the low voltage protection system during the operation of the mold closing mechanism. The injection molding machine needs to be equipped with a combined electromechanical-hydraulic safety protection system to ensure the safety of the mold and personnel. If the safety door is not closed properly before the mold is closed, the mold closing mechanism will stop working. During mold closing, if the safety gate is not closed properly, the mold plate will stop working or open automatically. During mold closing, if a foreign object such as insert falls into the cavity by mistake due to vibration, or a foreign object enters the mold by mistake, the mold will stop closing or open automatically and alarm.
Another safety system of the injection molding machine is the cold start prevention of the preplasticizing screw. It is forbidden to start the screw material before it reaches the specified temperature and holding time, otherwise it will alarm. The injection molding machine also requires protection at its nozzles to prevent burns caused by spilled material.
6. Degree of automation
High degree of automation, complete functions and high production efficiency Modern injection molding machines can be operated manually, semi-automatically and automatically. As long as the mold is properly designed, modern injection molding machine can operate fully automatically from injection to molding and then to product ejection. If equipped with robots, it can also achieve unmanned operation. Functions including core extraction and plugging, hydraulic nozzle control and fast runner probe heating can be programmed into the automatic process for automated cycles in the injection molding cycle.
High productivity is defined as a short product molding cycle per mold under normal injection molding process conditions. It reflects the combined performance of the mechanical, electrical and hydraulic systems of the injection molding machine. To ensure it, high quality hydraulic and electronic components and precision manufacturing processes must be used to improve the sensitivity and repeatability of the injection molding machine. Injection molding machine system.
7. Energy saving and environmental protection
Energy saving and environmental protection is an important indicator for choosing a good injection molding machine. Energy saving means that the injection molding machine works under normal process conditions with electromagnetic heating system, power drive system (including inverter and servo) and heat dissipation system. The design of the injection molding machine should be environmentally friendly. That is, work quietly without noise pollution, hydraulic oil leakage or excessive noise, and try to use environmentally friendly materials.
8. Easy to repair and maintain
The injection molding machine should be easy to maintain and repair, and its mechanical, hydraulic, electronic and electrical components should be assembled to facilitate its maintenance and repair. The versatility and standardization of the injection molding machine is also an important factor for users. Maintenance is one of the very important production costs.
