The most plastic parts are made by short run plastic injection molding in the world, because the most parts are small size and just need a short time to do the mass production in one cycle time. Normally, the cycle time is 30 seconds to 120 seconds and also called short run injection molding. Why it is popular?...
Are you looking to achieve (or impart) functional, performance, or aesthetic properties to your finished plastic injection molded parts? If so, you can use the techniques outlined below: 1. Digital printing One of the most common plastic part decoration techniques is digital printing on injection molded parts. In this technique, a thin layer of dye/paint is printed on...
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...
Manufacturers have relied on metals due to the abundance of favorable qualities they possess. Metals are stiff, strong, and have ideal characteristics related to electricity and chemical resistance. However, the need for reducing operational costs, complex designs, and fast-paced production is greater than ever. Plastics, fortunately, have some similar characteristics as metals and are their cost-efficient alternatives. While...
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...
Do you know the disadvantages of cheap plastic injection molding? Today we will discuss the disadvantages for the related industries. Being a professional injection molding factory, we knew some importers would like cheap injection molding because of the low price, they want to make big profits, so the business will be better? In my opinion, it’s a very...

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...
