How to Control the Temperature of Metal Powder Injection Molding

In the process of metal powder injection molding, the control effect is generally good. However, in the process of multi zone heating zone interaction, a model-based multi zone control may be more effective in reducing temperature overshoot and thermal hysteresis, which plays a very good role in the whole production. Therefore, it is necessary to reasonably control the temperature. Today, we will introduce how to control the temperature of metal powder injection molding. I hope it can help you!

Zhongwei precision metal powder injection molding manufacturers introduced that there are many forms of multi zone heating system, including furnace, heating plate, extrusion or injection molding equipment. Generally, temperature feedback control is used to control or drive the processing temperature required by these systems, so effective temperature control is a challenge. In these types of systems, because each area is not affected by the surrounding areas, interactive areas are created. In these applications, simple control can not be an effective regulator.

MIM experts consider a temperature double zone heating roller used to control the load. It has two heating zones arranged in concentric circles and corresponding temperature sensors. A dynamic coupling, multi input and multi output system is created at the position of the heater and sensor. The influence of one of the heating zones is shown in the two sensors. In practice, the pressing plate needs to operate different temperature ranges and adjust the interference due to the inlet and outlet of the load.

The leading manufacturer in the MIM industry of metal injection molding introduced that controlling the multi area system may meet some compromise performance requirements. Because one area setting will have an impact, it is a major deployment time to select the gain of the controller. At the same time, the response speed should be reduced to avoid interaction, as well as adjacent circuits and corresponding heaters, so as to control possible losses. In addition, the response speed should also be reduced to the load quality change. It is necessary to design a self defined feedforward control element to take up load input for MIM technology of metal injection molding.
