between the two pulse discharge, there should be enough pause time, discharge electrical corrosion products, so that the electrode medium fully deionization, restore dielectric properties, to ensure that each pulse discharge is not at the same point, to avoid local burns, in order to make repetitive pulse discharge smoothly.
WPC metal finish is effective on all surfaces inside and outside the machine where increased strength is required. This is especially effective for sliding surfaces and machine parts that require lubrication. If the WPC metal surface treatment process is carried out on a variety of machines with high friction, the machine will feel better. Because WPC metal finishing is not a new technology developed for an industry, it is not widely known. However, people gradually realized that it could increase strength and make parts compact.
General precision injection molds have two indicators, namely equipment accuracy and mold error. The former is difficult to compare due to the difference in size and product thickness, and represents the comprehensive level of injection molding machines. Generally, the weight repetition error of ordinary injection molding machines is 1%. A good machine can reach 0.8%, less than 0.5% is a precision machine, and less than 0.3% is an ultra-precision machine. So what are the main factors affecting precision injection mold products?
In the machining process of the CNC machining center, it is very important to avoid the collision of the CNC machining center when programming and operating the machining. Because the price of CNC machining center is very expensive, ranging from hundreds of thousands of yuan to millions of yuan, what are its advantages?
During the continuous operation of the mold, it is easy to cause problems such as wear of parts, deterioration of lubricants, water leakage, and crushing of plastic materials during the movement process, so mold maintenance is required.
Plastic mold is the abbreviation of a combined plastic mold used for compression molding, extrusion molding, injection molding, blow molding and low foam molding. It mainly includes a concave die with variable cavity composed of a concave die combination substrate, a concave die assembly and a concave die combination card plate.
