How to control the speed of plastic mold processing!

Why is the processing speed of this process goal important in injection molding, because it not only relates to the processing cycle of the part, but also determines the economic cost of processing. We often say that the EDM processing speed refers to the certain mass and volume that the workpiece is etched away in the same unit time under the condition of certain pulse parameters, which can be expressed by volume processing speed or mass processing speed respectively.

On the same surface roughness of the mold steel, the maximum processing speed of the relative electric pulse at the time of electrode loss is an important target for measuring the function of electric pulse processing and machine tool. In general, the manufacturer gives the maximum processing current and the highest processing speed that can be reached under optimal processing conditions. Therefore, when we practice machining, due to the ever-changing scale and shape of the workpiece, the machining conditions and the chip removal conditions are different from the aspiration conditions. Even in the roughing of the machining center, the machining speed is often much lower than the maximum machining speed of the machine tool. .

Each injection processing pulse discharge will leave a tiny pit on the surface of the workpiece. The size of the pit and the amount of erosion data are approximately proportional to the pulse energy, that is, the larger the pulse energy, the heat transferred to the workpiece. The more you will be, the more information will be erased. In theory, the speed of EDM is proportional to the single pulse energy and discharge frequency, but in practice, the effect of a single pulse is not manifested alone, but the result of multiple pulses together, the pulse power is continuous The process of transferring energy to the machining gap in a pulse condition is much more complicated. The processing speed is a multivariate function related to the pulse discharge timing, the pulse interval, the pulse discharge current, the pulse waveform, the processing target function, the electrode data, the chip removal condition, and the like.

Processing speed is very important in mold injection molding. Because this is a prerequisite for the production of plastic products. If the customer asks for a good quality based on the early delivery, the processing time and speed are the most important.
