In the past years, Plastic injection machine and mold developed very rapidly
in china, high efficient, automatically, large-scale, micro, precision,
high-life of the mold already exist in the china mold industry, the proportion
in china industrial production value is going up every year. Many large and
complicated mold already lift china mold a new high
level, in my opinion ,most china mold can replace
imported mold from Japan. German or USA .mold CAD / CAM technology has been
developed faster and faster and have already have a good performance in china
mold building, Rapid Prototyping tooling Technology and machine development have
made greater progress and has reached the practical stage of promotion, a new
generation of manufacturing technology and other high-speed CNC has launched
officially and start from idea to manufacture. In so many china mold
company’s view, the mold manufacture equipment should be
efficient, automated, easy to operate; what is the good mold? The
china mold company will answer: if the mold have
a rational fabrication, easy manufacture process, low cost. then it is a good
mold. Reasonable processing technology, advanced manufacture equipment,
precision injection production is essential three important factors for modern
plastic production,
Compare mold and other mechanical products, the important difference is high
technology and high net output in the whole proportion.
Injection mold design is part of the fast paced world of injection molding.
When working as a mold designer, you must be able to think of new ways of making
things, and be flexible and willing to learn new technologies. It might look
easy because of the powerful CAD programs, but actually, these programs are
merely the tools to help develop your design. In the field of injection mold
design you often must develop new and original methods of plastic
molding.
As the chemical industry, light industry. The annual growth rate of
China mold industry in recent years has been 13% to
15%, and all the industries and every company need more and more mold. The
situation of china mold market changes, high levels of mold are needed much more
than before. With the whole industrial development, People care more about
product quality and appearance that means we already bring higher requirement
for china mold companies. Therefore, the combination
of specific conditions in China, study from abroad and die and mold
manufacturing experience in building, scientific rationalization development of
the china mold technique can promote technological
progress.
Thermoplastic injection molding is the most important processing methods for
work piece production in nowadays.
If the plastic product is processed by this method, Variety and style is much
better than other ones. It is a process used in manufacturing to create a
variety of parts and components for industries ranging from aerospace to
automotive to construction. Thermoplastics, such as epoxy, are heated into a
molten resin and then injected into a mold that’s usually made from aluminum,
steel or a metal alloy. The molten plastic then gets compressed inside the mold
and allowed to cool. Machines remove the plastic component or piece from the
mold, and this hardened part can then be used to construct a larger product,
such as a child’s toy or an automobile door.
Therefore, the three necessary
conditions for injection molding: one must be melt plastic go into the mold
cavity; the second is plastic melt must be sufficient pressure and flow to
ensure timely and full of every corner of the mold cavity; the third is the need
for consistent shape and size of product and to meet the requirements of the
mold forming process.
Compared with other molding technology, Injection molding technology has its
unique advantages in the following aspects: first, forming the molten plastics
material and flow modeling is the difference in the plastic tube and two cavity
mold can always condensate quickly, cross linking will help shorten the molding
cycle; the other is injecting the plastic melt after lock the mold, Good
liquidity liposomal can reduce wear and tear on the mold cavity, which can be
molded with a large quantities of complex parts, surface graphics and mark a
clear and high dimensional accuracy of products; the third molding process,
mold, feeding, all production process are operated by the injection molding
machine automatically, so that fully automated injection molding process is
easier to control. But we must see the inadequacies of injection molding, due to
the cooling conditions, the system is difficult to use this technology without
defects, changes in wall thickness has a large thermoplastic products, as
injection molding machines and other injection mold equipment is very expensive,
initiation molding equipment investment is high, injection molding products are
not suitable for small batch production.
Also known as injection molding mold or injection molding, thermoplastic
molding is an important method of molding. Except for a handful of several
thermoplastics, almost all plastic parts can be molded with this method.
Injection Molding of various shapes can be molded to meet the demands of plastic
product. It has been successfully applied to some of the thermosetting plastic
parts, rubber products, and even other industrial production.
From above, China
mold have already developed to a new high level, if you have
any mold making requirement, please do not hesitate to contact us, any enquire
are welcomed!
