The application of Xindashida motion control systems in drip-molding machines in the plastics machinery industry.
Project Background
Drip molding technology leverages the property of thermoplastic polymers to change states: under certain conditions, they exhibit fluidity, yet at room temperature they can revert to a solid state. By employing appropriate methods and specialized tools to spray ink while the polymer is in its fluid state, it can be molded into desired shapes as designed, and then solidified and set at room temperature. Below are some applications of drip molding.
Customer needs
The upgraded and improved equipment needs to be easy to debug, operate smoothly, and enhance production efficiency.
Xinshida Solution
Proposal Description
Relying on CNC machining technology, Xindashida YunKong has replaced the manual dispensing step in the drip-plastic process with automated machine dispensing, significantly boosting production efficiency.
As shown in the figure, the dispensing machine adopts a gantry design and consists primarily of a bed frame, an operation and control system, an X/Y/Z three-axis motion system (driven by a servo system that operates ball screws), a feeding module, and a dispensing module.
The operation and control system primarily provides functions such as G-code toolpath machining, motion trajectory planning, dispensing valve plastic molding process control, HMI handheld touch-screen and button-controlled graphical processing workflows, and more.
The AC servo system of the X/Y/Z three-axis motion control system receives instruction signals from the control system. After power amplification and shaping, these signals are converted into linear displacement movements of the droplet molding machine’s actuating components. The performance of this servo system directly affects key technical parameters of the droplet molding machine, such as precision and speed. Therefore, it must exhibit excellent rapid response capability, accurately and sensitively tracking the digital instruction signals sent by the controller, faithfully executing commands from the higher-level controller, and enhancing both the system’s dynamic following characteristics and static tracking accuracy.
The drop-plastic machine relies on an X/Y/Z three-axis motion system to position the PVC paste dispensing needle precisely at the designated location on the drop-plastic mold. By controlling the duration of extrusion of the paste resin and the speed of the needle’s movement, the machine accurately regulates the amount of adhesive dispensed, thereby achieving the desired dispensing effect. The relevant operational procedure is as follows:

Scheme advantages
The application advantages of the Xindashida motion control plastic machinery solution are as follows:
• More dispensing valve controls, supporting up to 18 dispensing valves, enabling multi-formula functionality and supporting up to 36 product processing recipes.
• Add the capability for the host computer to configure parameters and upload or download files for networked devices online; support the host computer in collecting device operating data.
• Supports handheld touchscreen adjustment as well as full-keyboard operation; G-code and parameter processing supports importing and exporting via USB flash drive, maximizing convenience for operators during debugging.
• Supports a larger parsing cache, with a maximum of 30,000 G-code instructions per processed file;
• The CNC’s powerful acceleration and velocity profile planning ensures high-speed, smooth operation of the equipment, increasing efficiency by 8% to 10% compared to conventional models.
• After extensive testing and analysis, Sigriner has customized a set of servo system parameters tailored specifically for plastic molding processes. The newly developed automatic tuning feature—without the need for manual adjustment—of the Ω6s-ARR series servo saves 90% of the time typically spent on equipment commissioning.
