    Which product parts are more cost-effective to be processed with CNC?
    CNC is a versatile subtractive manufacturing method that starts with a piece of material and, depending on the design complexity of the part, uses CNC machines with different number of axes to remove a portion of the material until it is cut into a finished part. This fine rotary process allows for extremely high dimensional accuracy and compatibility with many materials, including plastics, metals and wood. This high degree of versatility allows CNC to machine almost most of the parts we use every day. So which product parts are more cost effective to machine with CNC?

    PE properties, processing technology and applications
    PE is one of the most produced plastics, characterized by soft, non-toxic, inexpensive, easy processing, good chemical resistance, not easy to corrode, and difficult to print. Properties of PE plastics It has many types, commonly used LDPE (low density polyethylene) and HDPE (high density polyethylene), translucent plastic, low strength, specific gravity of 0.94g/cm3 (smaller than water); very low density LLDPE resin (density below 0.910g/cc, LLDPE and LDPE density are in 0.91-0.925 (between). LDPE is softer, (commonly known as soft glue) HDPE is commonly known as hard soft glue, it is harder than LDPE, is a semi-crystalline material, after molding shrinkage is high, between 1.5% to 4% poor light transmission, crystallinity is large, it is easy to environmental stress cracking phenomenon. The cracking phenomenon can be reduced by using materials with very low flow characteristics to reduce the internal stress. It is easily dissolved in hydrocarbon solvents when the temperature is higher than 60°C, but its resistance to dissolution is somewhat better than LDPE. The high crystallinity of HDPE results in high density, tensile strength, high temperature twist temperature, adhesion, and chemical stability. It has greater resistance to permeation than LDPE. PE-HD has a lower impact strength. Properties are mainly controlled by density and molecular weight distribution. The molecular w

    3D printing manufacturing China and car heat exchangers
    Automotive heat exchangers are used to transfer heat between two media of different temperatures that are in thermal contact with each other. For example, in internal combustion engines, engine coolant flows in a circular motion through radiator coils and air flows through these coils to cool the engine. The automotive industry is an important segment for heat exchanger applications, and by the end of 2014, the automotive segment had a share of more than 25% of the global heat exchanger market. China has significantly increased its market share since the early 2000s and today has the highest share of more than 50% in the Asian automotive heat exchanger market. The demand for passenger cars and light commercial vehicles is expected to grow over the forecast period, leading to high demand for automotive heat exchangers in China. The increasing demand for reducing the weight of vehicles has led OEMs to replace heavier materials such as iron and steel with lighter materials such as plastic and aluminum. The automotive heat exchanger market has followed this trend.
