Plastic injection molding is one of the best methods for producing plastic parts. Thus, it doesn’t come as a surprise that the global market for the process was valued at around USD 260 million, with forecasts for continued growth in the foreseeable future. The technology is used in a range of industries, including automotive, medical equipment, and aerospace,...

The process of using high pressure to inject molten material into metal molds is known as plastic injection molding. Once the finished part is sufficiently cooled, it’s automatically ejected. The process is automated and can create large product volumes, especially plastic parts. To achieve these large volumes, preventative maintenance is important. Mold maintenance is important if you want...
Vacuum forming and injection molding are versatile manufacturing techniques that are used to make an array of durable, lightweight plastic parts and products. Both methods are cost-effective, require extreme heat, and involve the use of molds. Despite their main similarities, every process has a very different approach. Here, we compare and contrast injection molding versus vacuum forming, highlighting...
From general resin use to too much energy consumption and scrap, the injection molding process has raised some ecological concerns in the past. The alarm is neither unique nor surprising to injection molders or the industries they cater to. Currently, manufacturers are consuming a lot of electricity and generating a lot of trash – and, at PTMS, so...

‘Well, I have the CAD drawing, what else could they possibly require?’ If this statement sounds familiar, this blog is for you—and no, the CAD drawing isn’t enough to get a good plastic injection molding quote. A custom plastic injection molder could come up with a quote by looking at a CAD drawing (and in some instances, even...
Many industries use the plastic injection molding process due to its versatility. However, it’s not just popular because of its quick production but also because of the number of available materials. When manufacturers need to create parts or products with specific material properties, there are many injection molding materials to consider. Here, we highlight some of the main...
With hundreds of plastic injection molding companies in China, there’s no shortage of companies to choose from. When choosing an injection molding company, numerous factors must be taken into account, including delivery time, company reputation, cost, quality assurance, and capabilities. While finding the right plastic injection molder that aligns with your company’s needs may seem like a difficult...
Thermoplastics and thermoset plastics are two different forms of polymer powders, which are differentiated depending on their behavior on reacting to the application of heat. Here, we explore the differences between thermoplastic and thermoset plastic: Thermoplastics These are resins that are solid at room temperature. But when heated, they become soft and ultimately become fluid due to crystal...
Since injection molding offers greater efficiency at a lower cost, it’s useful for producing components for almost all markets, and is extremely versatile, as it holds a broad appeal. However, this doesn’t mean that accomplishing this process in-house is easy. Injection molding is also finicky and cost-intensive, and it’s difficult to achieve consistent results without troubleshooting know-how and...
Compared to parts with tight tolerances, normal injection molding tolerances are typically less costly to manufacture. This is why coming up with a specific part or the optimal tolerance is important to produce top-notch parts at affordable rates. Here, we discuss some best practices for improving injection-molding tolerances. Choose the ideal material for the application A material may...
Automotive plastic injection molding is popular in injection molding industry, because private cars become more and more in the recent years. Usually, the auto parts should be top quality. Who can provide such service? Normally, professional automotive factories can make such parts, but injection factory also can provide injection molding automotive service, the factory should have the points...

A top-notch injection molding tool is arguably the most important factor to produce a high-quality plastic product. Here, we discuss some tooling tips to create the perfect part mold. Strong mold design To get precision parts, exacting standards must be met, in both the design of mold components and in the cavities. It’s important to place gates correctly,...
When designing a plastic part, establishing a uniform wall is one of the most important decisions an engineer makes. The nominal wall influences the overall manufacturing requirements, the part performance, and the overall dimensions of the part. For the injection molding to work well, proper wall thickness is one of the most important design elements that should be...
How to deal with the used plastic injection molds? It’s an interesting question for an injection mold supplier. It will be many used injection molds every day because there are many factories in the world. We will discuss how to do this issue this time. Normally, there will be some points to deal with the used molds. Delivery...

If you’re looking to design a mold, don’t forget to consider the following important plastic injection molding design checklist. 1. Ribs Plastic has a stiff nature. Keeping this in mind, the inclusion of ribs in a design is usually suggested, which adds to the bending stiffness. There’s no better option than ribs when it comes to convenience and...
In plastic injection molding, the cooling time is one factor that substantially affects the overall quality of a product. Generally, a shorter cooling time signifies an optimized injection mold cooling system and greater output (in the long run). Here, we briefly discuss injection molding cooling times. How to calculate cooling time in plastic injection molding? To calculate cooling...
