Good plastic injection molding requires more than a good injection
molder. It also requires the customer to understand the importance
of using the right materials for the right product.
Using the wrong plastic simply means you'll end up with the wrong
product - and the wrong result in the field, namely failure.
It's important for part designers to do their homework before the
plastic injection molding begins and to answer the critical questions
that will help determine what type of material their application
will require:
-
What is the product's end use?
-
What environment will it be in?
-
Will the part be exposed to extreme conditions, such as sunlight,
heat or solvents?
-
Is impact resistance or flame resistance critical?
-
Is the appearance and feel of the part important?
-
How price sensitive is the application?
It's important, too, to test the material as it will be used, especially
since the final part's full requirements may not always be completely
obvious.
Material testing becomes even more important, considering the comprehensive
nature of many resin spec sheets. The sheets often list the best-case
scenario for each spec, even though those best-case scenarios could
be mutually exclusive.
A good plastic injection molding company can help point you in the
right direction during your material selection process.
It's best to involve your injection molder in the design process
as early as possible. They can suggest a range of plastic resins
for you to test and review, as well as help make sure you consider
every product requirement before making your final material selection.
And, if necessary, a good injection molder will help you realize
one of the facts many molders don't like to mention: Some parts
just shouldn't be made out of plastic.
