The development of modern injection molding machines is continuously innovating toward functional specialization, high-speed precision, and advanced automation.

(1) Functional Specialization and Cost Reduction In actual production, various types of specialized injection molding machines have emerged to meet the specific requirements of different product shapes and plastic materials. These machines feature high cost-effectiveness, intensive technology, and simplified structures. Typical examples include gas-assisted injection molding equipment, fusible core injection molding equipment, as well as magnet and metal powder injection molding machines.

(2) High Speed, High Efficiency, and Precision The mold opening/closing speed and injection speed of the equipment are being significantly increased. For example, the injection speed of small and medium-sized injection molding machines can reach 600 mm/s, with some even reaching 900 mm/s. At the same time, machines are evolving toward large-scale, ultra-large, and even miniaturized designs. For instance, large injection molding machines with a clamping force of 120 MN have already been developed. In terms of molding precision, the accuracy of ultra-precision injection molding machines has reached a level of less than 0.001 mm.

(3) Automation Automation is key to improving product quality and production efficiency. Modern equipment has widely adopted programmable logic controllers (PLC) and microcomputers for process control, enabling automatic adjustment of molding conditions and even achieving full automation and unmanned operation throughout the entire process, from material feeding to product inspection and packaging.

(4) Other Development Trends In terms of mechanical structure, the clamping methods are primarily toggle-type and direct hydraulic-type, forming standardized series. Overall, the development focus of modern injection molding machines lies in improving control levels, overall machine automation, and optimizing machine design and processing techniques to meet higher requirements for equipment quality and energy efficiency.
