Injection molding is the most common plastic molding process and is used to create a wide variety of complex parts of different size and shape. Whether it’s an overcap for a water bottle or a vinyl window part being manufactured, injection molding is efficient and economical, especially if high volumes of parts are being produced.
With 2018 on the horizon, you're probably already caught up in the frenzy of holiday and New Year planning. Before we say goodbye to 2017, let’s take a moment to look back at our most-read posts from the past year. We had a busy, exciting year creating content with the goal of helping individuals and businesses become better informed about plastic injection molding and U.S. manufacturing.
As we look towards 2018, if there are topics you'd like us to write about, please let us know by using our comments section below. Have a wonderful holiday season!
When creating a product that requires molding plastic parts, you have several processes to choose from, depending on the type of application and type of part you want to produce. Injection molding and blow molding are the two most popular ways to produce high quality, cost-effective plastic parts. But before you dive into researching different molders and manufacturers, you want to arm yourself with the differences between these two processes. Here's a quick guide to help you differentiate:
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.
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.
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.
