company news about What are the requirements for the processing speed of plastic molds?

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 being eroded in a certain pulse parameter and the same unit time. It can be expressed in terms of batch processing speed and batch processing speed, respectively.

On the die steel with the same surface roughness, the maximum processing speed relative to the electric pulse is an important index to measure the technical performance of electric pulse processing and machine tools. Generally speaking, the manufacturer will provide the maximum processing current to ensure that the mold can reach the highest processing speed in the best processing 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, a pulsed electrical discharge leaves a small hole in the surface of the workpiece. The size of the pit and the amount of etched material are directly 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. Theoretically, the EDM speed is proportional to the energy and frequency of a single pulse. But in practice, the effect of a single pulse is not reflected alone, but the result 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. The electrode material and Chip removal conditions.

Now we all know the importance of processing speed in injection molding, the editor also brings other content for you, continue to read!

Customers often ask the editor whether it is necessary to spray paint on the surface of plastic products. In fact, it depends on the specific usage of customers. The following editor will talk about the benefits of spraying paint 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 dark. If the surface of the plastic item 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 scrap rate of plastic products. The waste 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 concealed to a certain extent.

Therefore, spraying paint on the surface of plastic products with requirements is very useful, but what we need to know is that spraying paint will increase the cost of injection molding.
