I hope you found the first article on flash free molding interesting. [Read Flash Free Molding Part 1.] I covered cavity pressure versus clamp pressure and will talk tool deflection in this article. Tool design and construction can be a contributor to flash issues. But, if you read the first article and the three conditions are met, flash is not possible. An inadequate tool design can contribute to flash by allowing deflection in line with clamp force and perpendicular to clamp force. Also, on the construction side, improper spotting, timing of components, and fitting of components can be contributors to flash. (more…)
If you’re looking for an injection molder for your project, it is important you find one that suits your needs and offers you the best possible injection molding service. In all probability, you will continue using the same molder for all your projects, as long as you know for sure that he/she will produce quality plastic molded parts. So, whether your organization has designed a new product or improved an existing one, choosing the right injection molder could mean success or failure of your product.
Here are some tips to find the best injection molder. (more…)
Plastic injection molding pressures are classified based on the clamping pressure that the molding presses exert. This is the reason why it’s important to check the size of the press, which is often referred to as the tonnage. The clamping pressure exerted by the press can range anywhere from 5 tons to more than 4,000 tons. (more…)
“Design teams are always trying to come up with something better—better shapes and designs, better performance, better materials, and lower costs. They are constantly seeking something that will give them an edge over the competition.”
But being creative is harder when you’re dealing with metals. Regardless of how lean you go, cost is still the greatest factor. That’s why changing from metal components to plastic ones could save you up to 50 percent in operational costs without compromising function or quality. It caneven improve design choices and options, giving the design teams the creative license they need.
In this great article from Kaysun Corporation, they outline how injection-molded plastic can replace metal in many instances and what advantages plastic has over other materials.
Getting together with your injection molding team during the earliest design stages to discuss design for manufacturability (DFM) is an important practice, points out a great article from Kaysun Corporation. The up-front collaboration not only makes you a part of the process, but it can be a great way to help the environment.
“We all have a stake in doing whatever we can to protect our natural resources, water, and air. That’s why it is important for manufacturers to be proactive in reducing their consumption of natural resources, production of non-recyclable waste, and carbon footprint—which DFM helps us achieve.”
Up-front collaboration to discuss design for manufacturability simply puts more minds together during the injection molding process to create the best way to manufacture something.
