Colored plastics are used every day in a huge range of applications and settings, but very few people know — much less stop to consider — how these hues are achieved. With the help of Penn Color, a knowledgeable and experienced local colorant manufacturer who has a longstanding partnership with The Rodon Group, we have gathered information and insights into how the plastic products we know and use every day get their colors.
Although plastic injection molding has advanced significantly over the years, it's still based on the same standard principles it was years ago; today's technological developments have only further enhanced its versatility and reliability.
During plastic injection molding, plastic particles are melted down and injected into molds, which are chilled via water or a coolant that allows the plastic to harden. Once it has hardened, it is ejected from the mold and ready for use.
With Halloween right around the corner, we thought it would be appropriate to discuss some of the scary things to look out for when it comes to defects that can impact the quality of your plastic injection molded part.
When engineering the wall thickness of a plastic part, a careful balance of weight, geometry, and budgetary considerations must be maintained. For example, while thick plastic walls offer more strength, they also have a greater tendency to warp during the cooling stage of the manufacturing process.
Next Friday, October 6th is National Manufacturing Day. As a U.S. manufacturer, we are proud to be participating in this annual event for the sixth time and excited to open our doors to students and educators from local technical schools and colleges.
With hundreds of commodity and engineering resins available on the market today, the material selection process for plastic injection molding jobs can often seem daunting at first.
At The Rodon Group, we understand the unique benefits and properties of different types of plastics and work closely with clients to find the best fit for their project.
As plastic injection molding methods continue to advance and evolve, allowing for enhanced flexibility and more sophisticated customization options, molding companies must be able to stay ahead of the curve in order to offer clients the latest technologies and highest-quality end products.
As an American manufacturer and a family-owned business, we are always looking for ways to support the future of not only our company but other American manufacturers. We know the impact of STEM education on today's youth and often provide tours for high school and college students that are interested in careers in STEM related fields. And on Manufacturing Day, we bring students in with their educators to discuss the opportunities available and give them a close up look at what it's like to work for a highly automated manufacturer.
The success and precision of a part depends on the quality of its mold, but building a reliable, long-lasting tool can take a considerable amount of time — and requires a great deal of accuracy. Also, molds are often one the largest capital investments in a project, so it’s critical that tooling is built right the first time around. This is particularly important in high-volume injection molding projects, where molds can be extremely complex.
