Plastic
injection molding is one of the most popular methods for manufacturing parts in
the world. It is a versatile, simple, reliable, and very efficient method that
holds numerous advantages over other plastic molding methods. 

There shouldn’t be any doubt as to why plastic injection molding is and should be anyone’s top choice for parts manufacturing. To clear the waters for those that lack the facts on this matter, here are the top 5 reasons why it is the preferred production method for thousands of manufacturers worldwide. 

1.   Top Efficiency

Once the
injection molds are built according to the customer’s plans and technical
specifications, and the presses are programmed, the remaining process is very
fast compared to other types of molding.

It is a
process that has a high output production rate, can produce multiple parts from
a single mold, fast cycle times, all while producing consistent quality. All
that translates to a cost-efficient and effective manufacturing production
method. 

2.   Excellent Strength

Sometimes
fillers are added in the injection molds to reinforce the strength of the
parts. That’s when parts need to be durable, strong, or are in a harsh
environment that puts them at a lot of pressure. Plastic injection molding is
one of the rare processes that allows adding fillers to increase the strength
of the manufactured parts.

3.   Combine Various Plastic Types Simultaneously

Co-injection
molding is a feature that allows for combining different types of plastic at
the same time. It is one of the prevailing reasons why many manufacturers love
plastic injection molding. 

4.   Automation

Plastic
injection molding is a process that mainly relies on robotics and machines. In
most cases, a sole operator is all the human help needed to manage and control
the entire process. The reduced labor force lowers the production cost. Lower
cost of manufacturing is the direct path to increased profit margins, which all
businesses love to see.

5.   Complex Geometry and Detailed Features

Injection
molds are treated under very high pressure. Thanks to that, when plastic is
inside the mold, it is pressed very hard against its walls. That pressure is
much higher than in any other molding process. That makes it possible to
produce parts with detailed features and complex geometry. 

All other
molding processes are either too expensive or too complicated, while that’s not
the case with plastic injection molding. The level of complexity and the
intricate shapes possible with this molding process are by any account vastly
impressive. 

To Conclude

Plastic
injection molding is the type of process from which you get finished products
that don’t require additional rework. That’s just one of the many reasons why
manufacturers are in love with this process. 

Last but
not least, plastic injection molding is an eco-friendly process. All the
plastic scrap that is produced during the production can be easily re-grounded
and re-used. That means little or no waste at all.
