In the injection molding process, the processing speed is very important, because it is not only related to the processing cycle of the product, but also determines the processing cost of the product.
The EDM speed refers to the mass and volume of the workpiece eroded within a certain pulse parameter and the same unit time. It can be represented by batch processing speed and batch processing speed respectively.
On the die steel with the same surface roughness, the maximum machining speed relative to the electric pulse is an important indicator to measure the technical performance of the electric pulse machining and the machine tool. Generally, manufacturers will provide the maximum machining current to ensure that the mold can reach the highest machining speed in the best machining state. However, in the actual processing process, the processing conditions and chip removal conditions will be different from the ideal state, and the size and shape of the workpiece will continue to change, so the processing speed is often lower than the maximum processing speed index of the machine tool.
During each injection, the pulsed discharge leaves a small hole in the surface of the workpiece. The size of the pits and the amount of etched material are proportional to the pulse energy. That is, the greater the pulse energy, the more heat is transferred to the workpiece and the more material is removed. In theory, EDM speed is proportional to the energy and frequency of a single pulse. But in practice, the action of a single pulse is not reflected alone, but the result of the action of multiple pulses. Since the pulse power supply is continuous, the process of transferring energy to the machining gap through the pulse state is very complicated. The machining speed is a multi-function related to the pulse discharge time, pulse interval, pulse discharge current, pulse waveform, and the performance of the processing object. Chip removal conditions.
Now we all know the importance of processing speed in injection molding. The editor also brings you other content, keep reading!
Customers often ask Xiaobian whether they need to spray paint on the surface of plastic products. In fact, it depends on the specific use of customers. The following editor will talk about the benefits of spray painting on the surface of plastic products.
1. Spraying paint on the surface of plastic products can ensure the brightness of the products, because plastic products are difficult to reflect light and look very dark. If the surface of the plastic is textured, it will look darker. At this time, the customer will spray a layer of paint on the surface of the plastic product to pursue the beauty of the surface and ensure the brightness of the product.
2. Coating on the surface of plastic products can reduce the waste rate of plastic products. The rejection rate of white plastic products has always been a headache for the injection molding industry. If the surface is sprayed, the defects of the product can be masked to a certain extent.
Therefore, it is very useful to spray paint on the surface of plastic products with requirements, but we need to know that spray paint will increase the cost of injection molding.
