liquid chromatography HPLC peek parts Manufacturers

Speaking of plastic finished products friends are very familiar, we have a lot of plastic finished products around us, these products bring a lot of bento to our lives, in addition to our industrial manufacturing in life also appeared a lot of plastic finished products. Today's environment tends to be more and more demand for plastic finished products, so Changzhou plastic processing technology began to come out of our sight today, many people want to inquire about it but there is no channel, so this time we will briefly explain the related content to friends.

The peek material can be injection molded. PEEK is a high-temperature special engineering plastic and needs to be maintained at about 350 degrees. This requires the heating section of the injection molding machine barrel to continuously and stably provide a heating temperature above 350 degrees. The melting temperature of the peek material at high temperature is relatively high, and the viscosity in the molten state is relatively large, and the pressure required for injection molding is higher, and the wear of the screw is greater. In addition, peek injection molding requires heating, which is different from ordinary injection molding. It is recommended to find a manufacturer that specializes in peek injection molding to avoid certain technical risks.

As we all know, in CNC machining, there are many types of CNC lathe tools with different functions, and the effects of different tools are also different. Therefore, the choice of tools is very important. We need to choose the tools correctly according to different processing conditions. So how to choose metal CNC machining parts?

Compared with PTFE, the advantages of PEEK material are high strength, good wear resistance, high mechanical strength at high temperature, dimensional stability, good creep resistance, and injection molding.

The size of injection molding should not only meet the requirements of use and installation, but also consider the processing and manufacturing of the mold, the performance of the equipment and the flow of raw materials. Strictly control the factors that affect the accuracy of injection molded parts, including the manufacturing accuracy of the mold, plastic components and process conditions. The surface roughness of injection molding is determined by the roughness of the mold surface, so the surface roughness of the mold is one level lower than that of the product, and the requirements are met by grinding and polishing. The injection molded parts will produce cooling shrinkage in the mold cavity, which makes it difficult to take out the injection molded parts. Therefore, in order to facilitate demolding, the design should also consider that the inner and outer surfaces parallel to the demolding direction have sufficient demoulding slopes.

The injection molding process of injection mold can be roughly divided into three steps, first, temperature mastery; Second, pressure mastery; Third, the cycle of molding.
