Material Selection: How Do I Specify the Right Plastic for My Product Application

There are over 60,000 different grades of plastics and growing each year.  If you are developing a product that requires selection of a plastic, it can be quite a daunting task to determine the best plastic for your application among so many choices.  This article shares the methods we use to help our clients with material selection. Searching an Online Material Database There are a few online material databases but the one that we use most often is a well-organized site called which details the properties of many materials including plastics, metals, ceramics, etc.  While the website does have

How Should I Prototype? Machined Parts, Print 3D Parts, or Fabricate a Prototype Mold

How should I prototype? Machined parts, print 3D parts, or fabricate a prototype mold Introduction Once a design engineer completes the first draft of their product design, the next step is to create a plan for how it will be fabricated, tested, and developed. There are three basic methods of prototype fabrication: 1) CNC machining, 2)

How Much Does it Cost to Manufacture Plastic Parts?

Plastics are a very good fit for manufacturing and their use becomes, even more, cost-effective as volume increases.  Plastics are used to fabricate products in every major industry such as medical, automotive, electronics, housewares, etc due to their cost advantages.  Besides cost, plastics are often used in high-volume manufacturing due to the consistency of parts and the wide range of mechanical properties available through plastic material selection.  The purpose of this article is to inform you about how plastic part pricing is determined in manufacturing and how the number of cavities is driven by sales forecasts The Basic Economics of

Which Factors Determine Molded Part Accuracy?

You may have wondered which factors determine molded part accuracy and therefore the tolerances of the injection molded parts from both prototype and production molders. It’s a complex question that I will try to explain. Some factors that are within the molder’s control and some are not. The following factors determine molded part accuracy during mold fabrication and molding
