What are the parts of an injection molding machine?

An injection molding machine consists of several essential parts that work together to effectively facilitate the injection molding process. It can be divided into three main parts: the injection unit, the clamping unit, and a hydraulic system.

How do you choose an injection molding machine?

Start by identifying the size, complexity, and material types of the plastic parts you plan to produce. These factors will determine the clamping force, shot size, and injection pressure capabilities needed for the machine. It's important to consider your production volume requirements when choosing a machine to ensure efficient output. Make sure the machine is compatible with your molds regarding size, features, and the number of cavities.

What is the difference between a three-platen injection molding machine and a two-platen injection molding machine?

Horizontal three-platen and two-platen injection molding machines differ mainly in their structural design and operational capabilities. Two-platen machines have a simpler design with two large plates allowing easy mold changes and maintenance. This makes them well-suited for molding large parts that need high clamping force and precision. On the other hand, three-platen machines use a toggle mechanism with three plates, offering strong stability during injection. They are suitable for molding smaller to medium-sized parts with fast cycle times and precise control over mold movements.

Can Huarong's machines be customized?

Yes, Huarong offers a range of customization options for their injection molding machines, including modifications to clamping forces, injection units, and additional features to meet specific production requirements.

What support does Huarong offer after purchase?

Huarong provides comprehensive support including installation, training, and after-sales service to ensure your injection molding machines operate seamlessly.
