Ejector failure and mold sticking are common problems when using hydraulic injection molding machines, which often lead to production downtime, manual part removal, and increased material waste. And these problems are particularly serious in South American manufacturing environments, where high humidity and temperature changes can exacerbate resin adhesion to the mold surface. The main reasons… Continue reading Solve the problems of ejection failure and mold sticking of hydraulic injection molding machine

Unlike pneumatic or hydraulic robots, susceptible to compressibility, heat, and operating noise, servo-driven 3-axis robot provide clean, quiet, and highly repeatable motion with tight and precise speed control. This level of precision makes it easy to handle precision-molded parts, reduce scrap, and increase overall production. In addition, servo drives support complex motion trajectories. In high-speed… Continue reading Why do plastics manufacturers prefer a servo-driven 3-axis robot?

When communicating with customers at offline exhibitions and online, they often ask us questions about the impact of various mold temperature controllers on injection molding machines. As an injection molding machine manufacturer, choosing a water type or oil type mold temperature controller can significantly affect plastic injection molding machines‘ performance and production profitability. Water type… Continue reading Do different types of mold temperature controllers have an impact on injection molding machines?

When changing moulds, operators must wait for the new mould to preheat to operating temperature and the old mould to cool completely before removing it. This waiting time is often more than 30-60 minutes, leading to lost production time. A mould temperature controller with preheating function can automatically start heating one hour before the expected… Continue reading Why is the preheating function of the mould temperature controller so important?

When facing the injection molding production of high-speed and surging industries such as the high-speed packaging industry, it is necessary to make our injection molding equipment capable of large-order production and efficient intelligence. In addition to the core injection molding machine, a 3 axis robot is also required and integrated with the injection molding machine… Continue reading The importance of a 3 axis robot for injection molding in the high-speed packaging industry

Deeply influenced by Chinese tea brands, the global tea market has shown a comprehensive and substantial growth. In 2024 alone, the scale of China’s new tea industry has exceeded RMB 300 billion, and is expected to exceed RMB 400 billion by 2028. This growth has driven the simultaneous expansion of milk tea packaging, especially milk… Continue reading Why does the high-speed packaging industry need plastic injection machine?

When using an electric injection molding machine to produce pharmaceutical bottle caps, a common quality problem is insufficient injection, where the molten polymer fails to fill the entire mold cavity, resulting in incomplete bottle caps, which affects the seal integrity and sterility. Inconsistent melt pressure, temperature fluctuations, or insufficient injection speed can cause insufficient injection.… Continue reading How does an all electric injection molding machine address Short-Shot Defects in Medical bottle Caps？

When injection molding, mold temperature controllers ensure consistent part quality and cycle times. A critical but often overlooked factor is the thickness of the mold material itself. Mold material thickness directly affects the heat transfer rate, with thicker mold sections storing more heat and dissipating it more slowly, while thinner mold sections heat and cool… Continue reading Relationship between mold material thickness and mold temperature controller settings

Linear robots, also known as injection molding robots, are used in injection molding to insert inserts into the mold and to pick up and place finished parts after molding. However, positioning inaccuracies can seriously disrupt production, leading to misaligned inserts, damaged parts, and increased scrap rates. To remain competitive, manufacturers need linear robots that can… Continue reading How to solve the problem of inaccurate positioning of linear robots?

Clamping force refers to the force applied by the machine during the injection molding process to hold the two halves of the mold together and prevent them from separating under the pressure of the molten plastic. When purchasing injection molding machines, choosing the right clamping force ensures the molded part is formed accurately without defects… Continue reading How to choose injection molding machines with different clamping forces?

South America is experiencing a surge in demand for high-end consumer goods, from stylish electronics and home appliances to automotive interiors, medical devices and optics. These products require extremely high precision and perfect surface finish, which can only be reliably met by high-precision plastic molding machines. At the same time, local manufacturing companies are facing… Continue reading Why do South American manufacturers favor high-precision plastic molding machines?

If the injection molding robot misaligns when accurately picking and placing molded parts in high-speed production lines, it can cause part defects, production delays, and even equipment damage. For the injection manipulator robot, grasping errors are usually caused by problems such as poor synchronization with the injection molding machine or insufficient positioning accuracy of the… Continue reading Troubleshooting of misaligned gripping issues with the injection manipulator robot
