    2. Cast iron flat plane wave momentumThe plane wave gauge on the tablet, along arbitrary direction of a linear motion plane wave instrument. Mobile distance for tablet half the length of the diagonal and should not be less than 200 mm. Take...

Deformation of Investment Castings
    Flaring deformation: the forming reason is in the opening size of sand core and sand mold hindered the contraction of the casting, plastic deformation in the casting mouth free structural part, resulting in a flaring deformation defects.Warp...

Investment Casting Trace From The Deforma
    Trace the casting deformation is divided into: deformation, casting the flaring of deformation and warping deformation.Trace the deformation: alloy materials, gray cast iron is the most easy to trace the deformation.Grey cast iron shakeout...

Investment Casting Deformation Suggested
    For precision casting deformation ask advice measures:Find mold to shoot before 1. Shoot the wax wax room presets, until the mold temperature and shot wax wax room temperature phase began to shoot at the same time;As for the back shell makin...

Investment Casting Deformation Suggested
    3. Blow-in, module when high temperature also should avoid to overlap, do it regularly, so that the deformation in the same direction for plastic correction fashion clip.4. Calibration fixture should use hard material, casting surface wear r...

The Key Points of Heat Treatment Process
    The main technological factors of casting steel heat treatment:1. Steel heat treatment consists of three stages: heating, heat preservation and cooling.The determination of its parameters are in place to ensure that the product is based on t...
