China molding manufacturer
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 China Injection molding company with large quantities
up to one million, also suitable for the production of plastic parts with
complicate shape and structure. Thefollowing is 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 making 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.
