The future of the injection molding industry
The injection molding process is an essential production process for the production of various plastic parts. Injection molding has one of the most advantageous applications in today's mass manufacturing industry with large quantities up to one million, China molding manufacturer also suitable for the production of plastic parts with complicate shape and structure. Thefollowingis the advantagesinjection molding manufacturing:
✔ One-step molding from raw materials directly to finished parts;
✔ The injection molding manufacturing is fully automatic, which is conducive to improving production efficiency.
✔ Injection parts do not need post-processing usually;
✔ Suitable for mass production, greatly reducing the price of the product;
Usual plastics for injection molding manufacturing
Basically, there are different forms of materials for injection molding, China mold manufacturing most commonly used like thermoplastic, thermoset and elastomer, which differ from each property as shown below,
Thermoplastic: called plastomer. On the one side, it is a plastic and can be formed by heating arbitrarily. China injection molding On the other side, this raw material can be reformed by cooling and reheating in the liquid state, which is characteristic feature of the plastomer. Thermoplastics include plastics such as PE, PC, PET, PP, PVC and ABS, etc.
Thermoset: This material is usually brittle and hard (e.g. socket housing). After heating, the polymers are hard-crosslinked and deformed, this process is irreversible. This includes the plastics of PF, UP, MF, EP and SI etc.
Elastomer: It is elastic and bendable by hand because of its wide-meshed polymers, such as BR, SBR, NBR, EPDM, FRM, etc.
In order to produce the special injection molded part, it makes sense to add the additive of the plastic, colorant, stabilizer and plasticizer depending on the field of application of the molded part.
The future of the injection molding industry
At present, Injection molding cost with the development of "Industry 4.0" and the perfect combination of production and big data, the injection molding industry will become more intelligent. Research shows that there are still many links in the field of injection molding that need to be further optimized, and these must be promoted through continuous improvement of the process. In addition, with the further development of automation technology, the wide application of 3D printing, smart sensors, big data and new materials, it can be expected that the efficiency in the injection molding field will be greatly improved in the next decade, which makes the injection molding process more and more cheap Attractive.
Smart sensors: Injection molding is a very delicate process, which needs an attentive controlling. It will become more intelligent and more innovative in different units with sensors, ranging from in-mold parameters to Machine parameters, big data and quality control of produced parts. These intelligent sensors are expected to improve to solve the problem which is difficult to foreknow in the process.
Big data: Using big data is a new technologies emerging in recent years in molding technology. It makes the process more comfortable to track their molds in real-time. This process helps to monitor mold output as well as mold maintenance.However, it is achieved by connecting molds to a central internet connection server.
3D printing：Using the 3D printing for injection tooling has a vast interest, as this implies that it affects almost every aspect of mold and molded part manufacturing. Following are some advantages of tooling from 3D printer.
Automation: The use of robotics and automation had earlier been initiated in the molding and tooling industry, because of its speed and accuracy over a long duration. However, it would be challenging for conventional injection manufacturer to stay business, as the use of automation and robotics would have revolutionized the molding industry by next few years, handling all the required processes from start to finish. Virtually, every part of the molding industry has and sure will be affected by this unusual trend soon.
In short, the intelligent development of injection molding manufacturing will come slowly, and the future molding technology will undergo huge technological changes as the market changes, which will definitely promote the progress of the entire industry.
