We are pleased to announce that we are now offering compression molding of custom rubber parts. Compression molding is now the 4th custom manufacturing process we offer, complementing injection molding, CNC machining and urethane casting. Compression molding is the process where a heated rubber material (the charge) is placed in one side of a mold, then the other side of the mold is clamped down, and the rubber material is compressed into the desired shape. One of the biggest benefits of compression [...]
Image: Plastics Technology Plastic injection molding shrinkage is the contraction of a plastic molded part as it cools in the mold, and even after ejection. There are multiple factors that contribute to the amount of shrinkage a particular plastic part may undergo, such as the type of plastic material, wall thicknesses, and processing parameters. Mold makers must factor in shrinkage and compensate for it when making the injection molds that will make the plastic parts. So how do they know how much [...]
When you need custom plastic parts fast, you need every step in the process to happen fast. It all starts with a price quote, and you don’t have time to wait days for it. At ICOMold, we have an online quotation system that provides INSTANT quotes for your injection molding, CNC machining or cast urethane project. Not only is your quote instant, but it’s also interactive. If you change your part quantity, material or other options such as a multi-cavity [...]
Some injection molding companies use steel molds, and some use aluminum molds, for various reasons. There are pros and cons for each of the materials, but here at ICOMold we make steel molds because of the advantages they offer to our customers. One advantage is that steel is more easily modifiable in the case of a part design change. Another advantage is better durability. For an in-depth discussion of the advantages of steel over aluminum, please visit this page of our website.
We are pleased to announce the release of a new video that explains the upgraded features in our online quotation system. Recent system upgrades provide an improved user experience with a more intuitive interface and streamlined navigation. A new organizational layout makes it easier to quickly find the important elements of your quote, plus a new color scheme complements our branding. At just under four minutes, the video gives a concise overview of how quick and easy it is to get [...]
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 [...]
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 [...]
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.
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
This infographic describes the secondary (post-molding) processes we offer for custom plastic injection molded parts.
