    CNC machining process For example, certain positioning reference surfaces need to be machined easily and accurately in the semi-finishing stage or even in the roughing stage. Sometimes in order to avoid the conversion of the dimensional chain, in the finishing stage, semi-finishing of certain secondary surfaces can also be arranged. After determining the processing method and processing stage of t...

  • How to Choose the Right CNC Material for Your Part (2) Nov 16,2020
    How to Choose the Right CNC Material for Your Part (2) Plastics Plastic material can be a less expensive alternative to metals if the design does not require the rigidity of metal. Polyethylene is easy to machine, and it is about 1/3 the cost of 6061 aluminum. ABS is typically 1.5 times the cost of acetal. Nylon and polycarbonate are approximately 3 times the cost of acetal. Although plastics coul...

  • Difference between 304, 304H and 304L Nov 02,2020
    In fact, the content of chromium and nickel is 304 stainless steel, and the composition contains 18% chromium (Cr) and 8% nickel (Ni), but the main difference lies in the carbon content. 304, 304L, 304H chemical composition (%) table. 304L is an ultra-low carbon stainless steel. The carbon content is reduced to less than 0.03%, which can avoid intergranular corrosion. In theory, the effect of stre...

  • Let's talk someting about the copper nut Mar 23,2020
    Today let us talk something about the copper nut. The definition of a copper nut is a nut made of copper (usually lead brass, such as H59, H62). The copper nuts we come into contact with daily are mainly hexagon nuts or other copper nuts that match the bolts. So why use copper nuts in daily production activities? Because the copper screws and nuts has the advantages of not being easy to corrode, a...

  • About die casting process(I) Oct 08,2020
    Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Molds are usually made of higher-strength alloys. This process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die ca...

  • About die casting process(II) Oct 22,2020
    Die Casting Equipment Die casting machines can be divided into two different types, hot chamber die casting machines and cold chamber die casting machines. The difference lies in how much force they can withstand. The typical pressure range is between 400 and 4000 tons. Hot chamber die casting Hot chamber die casting, sometimes called gooseneck die casting, has molten liquid and semi-liquid metal ...
