How did QQS Mould achieve a 10-micron tolerance (±0.01mm) on a glass-reinforced PBT surgical handle? Discover our data-driven 4-step precision approach to medical molding.

Overmolding is more than just a soft grip—it's a critical engineering bond. In this week's technical deep-dive, we analyze how we achieve molecular fusion and mechanical interlocking for high-durability power tools and hermetically sealed medical devices. See how we use JSW precision and cleanroom SMT to deliver market-ready hardware for global brands.

What is Injection Molding: Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession. Why Use Injection Molding: The principal advantage of injection molding is the ability to scale production en masse. Once the initial costs have bee...

When molds and tooling are mentioned, what comes to mind are the parts that are produced through the use of processes like injection molding or plastic extrusion, blowing molding. These parts can be used for a number of different purposes across different fields and industries, and getting them right the first time is extremely crucial in the success of whatever process they will be used for. Mold...

Injection Molding for Thermoplastic Elastomers  While people are talking about thermoplastic elastomers, we usually easily think of TPE.The injection molding process is adapted to TPEs rather readily. The various classes of TPEs will generally mold well. Historically, the thermoplatic urethanes were the exception due to their high viscosity, but in recent years TPU grades that injection mold ...

Plastic Injection Molding: Overmolding The overmolding process is to make a new part using a combination of two or three or even more kinds of plastic or elastomer materials. During the plastic overmolding process, usually hard material is first-shot, and then soft material will be the second shot over the first layer molded part. What is Overmolding? Overmolding is used for a range of application...

The "pass message to eliminate coronavirus" campaign promotes five key steps. People can follow WHO's guidelines to prot...

In 2020, the global outbreak of COVID-19 had a sudden impact on people's lives.  Compared with the flu, the COVID-19 has more infectious and destructive power. Moreover, as an emerging virus, now there is no specific effective medicine or vaccine for it. Therefore, prevention is the best way to deal with the epidemic at present. In this article, we will discuss with you what may help prevent ...

Recently, we have developed several porjects, which will be a plastic container with sealing. So, all customers imposed that "No warpage or shinkage is allowed on the contact surfaces". Here in this article, Qiqiangsheng Moulds will share the tips about how to solve the warpage & shrinkage problems for plastic molded parts. Usually, the molding defects were caused by below points: 1, Part desi...
