Pumpkin Spice-Flavored Amorphous Plastics?

Back in July, we announced our new penguin-shaped plastic material performance chart. It compares the temperature range, relative cost, and performance characteristics of common crystalline and amorphous plastic resins. (Why penguin-shaped, you ask? Because it’s more fun than a boring old triangle or pyramid). The response was overwhelming – a lot of people downloaded the penguin chart. So, since we’ve added new people to our mailing list since then (and in case you missed the original), we decided to dress [...]

Part Design Guidelines for the Plastic Injection Molding Process

For design engineers who are new to designing for plastic injection molding, there can be a knowledge gap in making sure the CAD model is properly designed for this manufacturing process. There are certain, very specific design features that must be considered in the design stage in order to avoid moldability issues that can produce undesirable results in the molded parts. If they’re not considered from the beginning of the design process, and they’re not discovered until the Design For [...]

Custom CNC Machined Plastic or Metal Parts

CNC machining can be a good option for manufacturing prototype or low-volume plastic or metal parts. For plastic parts, CNC machining allows you to test the form, fit and function of prototypes prior to tooling up for the injection molded production parts. For both plastic and metal, CNC machining provides a fast turnaround and low cost for small quantities of parts. To learn more about our CNC machining capabilities, please visit the CNC machining page of our website.

New Acronyms Describe Our Custom Digital Manufacturing Services

As a custom digital manufacturer, we provide the services described in this article by Digital Engineering. But “DE” does introduce a couple of acronyms that are not really mainstream: MaaS – Manufacturing-as-a-Service, and IMO – Injection Molding Output. “Injection molding output (IMO) is sold as a service, instead of purchasing an injection molding press, auxiliary equipment and robotics…” http://ow.ly/yTL630pEaR1

Custom Plastic Injection Molds – Shipped to You

When we build a plastic injection molding tool for a customer, the tool usually stays in our manufacturing plant so we can run parts for the customer whenever they need them. We call these “Production Molds,” and the process is “On-Demand” manufacturing. Sometimes, however, the customer is another injection molder who wants us to build their mold, but they want to run the plastic parts themselves. Or the customer wants the mold shipped to some other injection molding facility where [...]

Comparing the Piece Price of Injection Molded Parts to 3D Printed Parts

Advantages of Injection Molding Over High-Volume 3D Printing While 3D printing doesn’t have the upfront cost of a mold, as injection molding does, it also doesn’t reduce the unit cost over time, and injection molding does. Plastic injection molding can quickly become the more cost-efficient option with a production run of as little as a couple hundred units. In this example, it becomes cheaper to produce the part by injection molding at 252 pieces compared to 3D printing. Additional advantages of injection [...]

Using Interchangeable Mold Inserts to Save Cost

Interchangeable Mold Inserts for Similar, But Slightly Different, Parts Sometimes there is a need to injection mold multiple versions of a part. The parts may be identical except for one minor variation. In the example in the illustration, one part has two tabs on the center section, while the other version is just smooth on the center cylinder. Another example could be having one version of a part with a logo molded into it, while another version is smooth/unbranded. Using interchangeable mold inserts [...]

EMI Shielding for Plastic Parts

Copper Paint Coating for EMI Shielding If you need electromagnetic interference (EMI) shielding for plastic parts that house electronics, copper paint coating can be a good option. Copper conductive paint is widely used in higher frequency EMI shielding applications (>30 MHz). While other conductive paints like silver or nickel may be more appropriate for some applications,  copper is a common, low-cost EMI paint. There are some considerations you should be aware of when designing plastic components that will require EMI shielding. For [...]

Case Study: An Inventor’s Product Development Journey

The SlingBaron: World’s First Twirling Harmonica Dryer An inventor’s journey through the product development cycle can be very difficult, time-consuming and costly. It was all three for Mike J. Baron, inventor of the SlingBaron, the world’s first twirling harmonica dryer. Mike is a longtime inventor and harmonica player who combined these two talents to develop a problem-solving product and bring it to market. The development process wasn’t easy for Mike, but his persistence and belief in his product drove him to continually [...]
