1. The cost of a plastic injection 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. 

2.  Cold runner versus hot runner molds

Every plastic part starts in a mold.   Molds are classified into two main types, cold runner and hot runner.  Each has its advantages and disadvantages.   Your plastic injection molder will be able to give you the costs and benefits of using these different systems.  However, by understanding the key differences of these technologies, you can have a more educated discussion on the type of mold that would best fit your project. 

3.  Scary plastic part deflects and how to avoid them

When purchasing injection molded parts, it is important to understand some of the common but scary problems and defects that impact product quality.  Being familiar with these imperfections and their causes can help you work with injection molders to insure the highest quality part production is achieved.

4.  Types of plastic molding

In today’s manufacturing environment, plastics are being used to make everything from automotive body parts to human body parts. Each application requires a special manufacturing process that can mold the part based on specifications. This article provides a brief overview of the different types of molding and their advantages and applications including information on blow molding, compression molding, extrusion molding, injection molding and rotational molding.

5.  The basics of an injection molding machine

While plastic injection molders will help you determine the size of the machine needed to get the best result, a project designer or engineer can get a good estimate based on some basic information.   By knowing approximately what size machine will be required, you can better source a plastic injection molder that will meet your needs.
