CNC lathe machining parts Manufacturers

There are many reasons for the workpiece overcut in cnc processing. If the workpiece is overcut, it will be repaired after welding, and the workpiece will be discarded directly. Especially when the large mold is processed, it is the most troublesome thing to encounter the workpiece overcut. How to deal with it, I will share with you my work experience below.

For many large-scale equipment, machined parts are indispensable during production and assembly, and the quality of machined parts also determines whether the performance of the entire equipment can be fully released. At the same time, good machined parts can also extend the equipment. service life. There are also many factories on the market that produce machined parts. When producing machined parts, you should pay attention to the following matters in order to make better products.

the selection of injection molding materials for small household appliances

The characteristics of plastic injection molding are determined by the characteristics of the raw material, and there are two main points: one is the filling activity of the plastic melt during injection, and the other is the shrinkage position of the plastic in the mold cavity when it is cooled and cured. These two points determine the difference of the injection mold and the difficulty of the injection mold design. When designing injection molds, it is necessary to inquire about the characteristics of the processed plastic raw materials, so that the designed injection mold is more reasonable, and the characteristics of plastics are usefully exercised in the design process. Therefore, the questions that need to be considered in the injection mold design process are as follows.

The English name of PEI Chinese polyetherimide board is Polyetherimide, PEI belongs to amorphous plastics. It is an amorphous high-performance polymer, which is extruded from engineering plastics made of amorphous PEI (polyetherimide) at high temperature by an extruder. At present, the commonly used PEI board is the raw material (Ultem) of GE in the United States. In 1972, GE of the United States began to research and develop PEI.

PC material has the characteristics of high strength, good transparency performance, low molding shrinkage, good processing performance, etc., let's analyze the injection molding process of PC material and the selection of screw. PC plastic process characteristics
