  • Production Line

    Carbide is a composite material including of particles mainly with tungsten carbide as hard material and a metallic binder . For this reason , with carbide it is possible to achieve hardness and toughness combinations which can’t obtained with other materials .

     

    1.  Powder Production

     Both tungsten carbide and cobalt powders come from carefully selected suppliers, and each batch is carefully tested in the laboratory.

     

    ZHUZHOU APPLE CARBIDE TOOLS CO.,LTD.

    Due to its high melting point tungsten carbide (WC)can only be produced through sintering when needed for technically sophisticated applications . For this purpose , the powder consisting of the tungsten carbide ,the cobalt binder and sometimes additional alloys is mixed , milled and spray-dried .

                                                                              Ball Milling 

     

    This process results in a spray-dried granulate which can easily be used for production ,since its chemical and physical properties have already been adapted to the final carbide specification

     

    The spray drying helps to dry the abrasive slurry, making the particle size more uniform, improving the metallurgical structure, and allowing the matrix insert to have higher strength.

    2. Manufacture of carbide blanks

     

    By applying pressure the carbide powder is converted into a blank .

    Imported automatic press with a maximum pressure of 12 tons, each blade is weighed and controlled by the operator at certain intervals to ensure high precision of the blade.

    The sintering process converts the blank into a homogeneous piece of carbide with a high degree of hardness .When sintering hard metal (usually at a temperature of approx.1400 c ) , this process is called liquid phase sintering . In this case ,the binder (e.g. cobalt ) melts and wets the WC hard material particles .After sintering , the density of the carbide is almost , or even precisely, the same as the theoretical density . Any residual porosity which occurs after the sintering procedure may be removed through an ensuring HIP process .

    3. Surface Treatment 

     

    The blanks need clear surface before coating , so we do the ultrasonic cleaning

                                                                                  Passivation

     

    Most inserts are coated by chemical vapor deposition (CVD) or physical vapor deposition (PVD). The thin coating makes the insert harder and tougher. This is also where the insert gets its specific color.

     

    PVD: Stable and consistent performance during processing.

    Improved thermal performance helps reduce sudden breaks and reduces edge wear

     

    CVD: CVD coating with enhanced resistance to chipping and abrasion

    Thick (Al2O3) has excellent heat resistance and ensures longer tool life by reducing the amount of wear. The unique surface structure of the coating resists soldering and chipping of the insert during the cutting process.
