CNC drilled fittings Manufacturers

PEI (Chinese name polyetherimide) is a thermoplastic engineering resin with an amber transparent solid appearance. It has excellent heat resistance, high strength and rigidity, as well as a wide range of chemical resistance, which can meet higher heat. Chemical and elastic demand. Its unique torsional strength among thermoplastics makes it an inexpensive alternative to small steel cutting parts. As an amorphous thermoplastic polyetherimide, PEI resin combines high performance and excellent processing characteristics, combining high heat resistance with high strength, modulus and extensive chemical resistance.

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?

CNC (Computer Numerical Control) machining is a highly versatile manufacturing process capable of producing parts from a wide range of materials, including plastics. This technology utilizes computer-controlled tools to shape materials with precision and efficiency. When it comes to plastics, CNC machining offers numerous advantages, making it a preferred choice for creating prototypes, custom parts, and even small production runs.

Plastic CNC machined parts refer to components made from plastic materials that are manufactured using CNC (Computer Numerical Control) machining processes. CNC machining is a subtractive manufacturing method where computer-controlled machines precisely remove material from a plastic workpiece to create the desired shape and dimensions.

Product design: Plastic product processing holds rounding and increases the demolding slope. Mold: 1. Mold surface polishing. 2. Pull the white status growth thimble. 3. Confirm that the parting surface has no inverted buckles and air spurs, and repair it with oil stone. Injection molding process: 1. Under the premise of thorough filling of the clad product, accept the lowest possible injection pressure. 2. Confirm that there is no problem with the size and appearance of the product, reduce the holding pressure, holding time or cancel the holding pressure. 3. Adjust mold temperature and cooling time. When we are in the injection molding of plastic finished products, we usually encounter the idea of product whitening, we can first analyze the whitening from the methods of man, machine, material, method and ring, and classify and summarize all the components that affect the product; Re-examine the process opened up by the product.

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.
