There might be a lot of molding companies available around your location but selecting the best plastic injection molding company is always a difficult task. Lets find the steps to be followed while choosing the company.

2.  Plastic injection molding is a process of
manufacturing thermoplastic and thermosetting
plastics.
 Plastic injection molding constitutes different stages
in which the material is first sent through a hot barrel
and melted down for mixing and then it is sent into a
mold to cool and solidify in to the shape of the mold.

3.  Evaluating a plastic molding company
 Considering the cost
 Learning the history
 Finding their capabilities and specialties
 Considering quality of the molder and delivery time
 Finding the quality of the products produced
 Considering the location of the supplier

4.  The first and foremost thing to know when evaluating
a plastic molding company is finding what you need
them to mold for you.
 You must prepare a completely defined 3d model of
the plastic component along with specifying the draft
angles, surface textures and maximum allowable flash.

5.  The next factor to realize when choosing an injection
molding company is the cost. Buying the products in
China or Korea would be much cheaper but the delay
in getting the product would be more.
 You need to be wiser when choosing and you should
also consider the restrictions on price based on the
project your company is working on.

6.  The next important thing to consider is learning the
history of the company and their potential. Try to find
how long they have been on business and what
industries do they work for?
 If you need to manufacture a product that requires
tight tolerances, it would be better to choose a plastic
molding company that deals with health or
aeronautics industry than a company that molds toys.

7.  Once you have known the background, try to find
their capabilities, specialties, the presses they use and
how old they are? Also find if they would be able to
handle the volume you require?

8.  Apart from considering the lower component cost, you
should also consider the quality of the molder and the
delivery time. Lower molding costs wouldn't be an
overall savings for you always if there is a high delay in
delivery and the product is of lower quality.

9.  Take some time to find the quality of the products
produced by the company. Also check if they are a
certified company and they do control charting?
 What would be their action plan if they find an useless
product during audit?

10.  The final thing to consider is the location of the
supplier and how will this impact on your working
relationship?
 Choosing an injection molding company near your
location would be much better than choosing a
company overseas because you can just visit your
supplier any time when issues arise instead of
spending thousands of dollars per visit.
