The process of plastic injection molding has been around for years.  And over time injection machines, resins, and mold-building technology have greatly improved.  However, the basics still remain the same.  You take plastic pellets, melt them, and fill a mold with the melted plastic; the result, once cooled, is a plastic part.


Seems pretty straight-forward, right?  Well, the complexity comes in the details.  There are many variables that need to be taken into consideration when planning a plastic manufacturing project.  What is the end use of the part you want to produce and what are the dimensions?  Does it have some complex feature or geometry? What type of plastic will be used?  What plastic manufacturing process is best-suited to the project?  Would rotation molding work better than injection molding?

A manufacturing partner, like Rodon, can help you flush out a great many of these details, but why wait.  Why not educate yourself on the various types of plastic manufacturing and whether or not injection molding is the right one for you?

Our eBook was designed to help you on your manufacturing journey.  It provides top level information to help you make informed decisions and get the best possible outcomes.  The chapters include a review of the types of plastic molding, how to achieve perfect parts and common part defects; all in an accessible format.

Here is an excerpt from the chapter on determining the cost of a mold.

A common question for designers and engineers is “How much will a plastic injection mold cost?”  It makes sense.  Injection molds represent the greatest expense in upfront production costs.  And, there are many factors that go into determining the cost.  With any custom injection molding project, your injection molder will be able to give you the final price tag.  In this article, we will review the variables that can impact the cost so that you can be better informed in making a mold purchasing decision. 

Not all quotes are created equal

Procurement and purchasing managers have the unenviable task of obtaining quotes from a few mold makers for each project.  Depending on the input (in terms of drawings, prototypes or sample parts), the cost quotes can vary greatly.  Designers should look at all of these inputs and determine the best molding solution.  They may re-design the part to maximize manufacturing efficiency and increase the number of parts that can be made with each molding cycle.  Generally, molds made with tighter tolerances, more cavities and longer production life will take longer to build and will cost more upfront.  The savings with a high-quality mold are long-term.  These molds require less maintenance and last longer than lower quality molds.
