Top Things to Consider When Assessing Ejector Pins for Breakage

Ejector pins are a critical component to the injection molding process. An ejector pin is driven into the rear of a mold cavity to force the finished piece out and is also often referred to as a knockout pin. Having pins you can count on can make the difference between manufacturing a product efficiently or creating future unwanted costs.

If you’re experiencing ejector pin breakage here are some things to consider when assessing your pins:

Understanding Differences in Hot Runner Heater Technologies – Manifolds

All hot runner systems need a heat source to operate as designed, however not all hot runner systems are heated by the same methods. The type of heater technology your hot runner system uses can significantly affect molding performance, molded part quality and system cost. No heating method exists that is ideal for every scenario and each one has their own pros and cons but illustrating their differences may help you in understanding how your hot runner system is constructed and provide you with some additional insight on your next purchase. Some hot runner systems may use a mix of heating methods depending on the components of the system and application but for the purposes of this discussion we will focus on manifold heater elements.

NPE 2018 Recap

This May, Milacron participated in The National Plastics Expo or NPE as it is more commonly known. NPE is a triennial trade show and the largest of its kind in North America. Businesses associated with plastics in any way exhibit, visit and make purchase decisions at this must-attend event. This year’s show was held May 7th to 11th in Orlando, Florida and was one for the record books. It was the largest in NPE history with 2,180 exhibitors and 1.2 million square feet of exhibit space.

All hot runner systems need a heat source to operate as designed, however not all hot runner systems use the same heating methods. The type of heater technology your hot runner system uses can significantly affect molding performance, part quality, and system cost. No heater method exists that is ideal for every scenario and each one has their own pros and cons but illustrating their differences may help you in understanding your hot runner system a little more and give you a bit more insight on your next purchase. Some hot runner systems may use a mix of heating methods depending on the components of the system and application but for the purposes of this discussion we will focus on nozzle heater elements.

Weight Reduction in Blow Molding Containers

There are many opportunities today that exist in reducing a containers weight, often referred to as “light weighting”. The challenge lies in designing a container along with the tooling that allows for weight reduction, without sacrificing the containers aesthetic appeal, top load requirement, impact performance and stability.  Industry experts have dedicated a significant amount of time to mold engineering design and researching “light weighting”.

Industry 4.0: The IoT Revolution

Industry 4.0 and the Internet of Things (IoT) are synonyms for connected devices that allow the owner to gain more efficiency and productivity from their equipment. The ability to control light switches in a home with a voice command, t-shirts that recognize your heart rate while exercising, utilizing smart technology in your refrigerator to know when you need more milk, or adjusting your HVAC remotely utilizing an intelligent thermostat. Each of these solutions offer a clear path to enhancing your productivity and saving you money.

What is Co-injection?

Does your food or beverage packaging need an oxygen barrier, light blocking, or carbon dioxide retention for extended shelf life? Are you molding a part that could be filled with regrind? Do you want to differentiate yourself on the shelf with aesthetic packaging by implementing color gradation, foaming or other effects in your package? If you responded yes, then co-injection technology could be right for your application.
