  • Difference between forged bucket teeth and cast bucket teeth Although the bucket tooth is a small part of earthmoving machine and the price of which is relatively low, but strength and durability are the undoubted factors that must be considered when choosing. Among various types of bucket teeth, usually forged bucket teeth and cast bucket teeth both are wear-resistant. But the forged bucket teeth offer more wear resistance and hardness, the service life of which is 2 times longer than that of cast bucket teeth.
  • Casting process

    This manufacturing process begins with pouring molten metal into the cavity of mold which has a duplicate pattern of the bucket tooth. After cooling, the bucket teeth are removed from the mold.

    The casting process may cause air entrainment during metal pouring, and will produce excess metal when two sections of mold are attached together. The mechanical properties and wear resistance of cast bucket teeth are not good enough comparing with forged teeth.

  • Forging process Forged bucket teeth are produced from steel billets through innovative forging process. By utilizing forging machine to produce extreme pressure along with high temperature to extrude and form, grain flow of steel is optimized to provide enhanced mechanical properties. After being forged, the bucket teeth are characterized by high impact strength, better wear resistance and longer service life.
  • Benefits of using bucket teeth
    1. Bucket wear protection, can protect bucket edge against dust and stone impacting;
    2. Can provide operator with better edge sharpness and penetration for increased bucket loading capacity;
    3. Excellent impact absorption when digging rock bed or hard clayey soil;
  • How to avoid bucket teeth damaging due to abrasive wear
    1. When an excavator is digging, the wear volume loss of the outermost bucket teeth at both sides is 30% higher than that of innermost one. After being operated for a period, the innermost and outermost bucket teeth are better to exchange their positions;
    2. Operator should pay attention to digging angle when operating an excavator, it should be perpendicular to the object surface, preventing bucket teeth from breaking caused by excessive inclination;
    3. Excavator arm should not swing in horizontal direction when there is a large resistance, otherwise it is easy to cause the breaking of bucket teeth and seat since the horizontal forces are too large;
    4. The wear status of bucket tooth seat is also a critical issue that can affect the service life of excavator bucket teeth. It is better to replace the bucket tooth seat when its wear volume loss reaches 10%, because the large gap caused by the wear will change the force bearing point between tooth seat and bucket tooth, which may result the breaking of bucket teeth;
    5. Operating method also plays a very important role in increasing the utilization rate of bucket teeth. The excavator operator should pay special attention to the coordination of the operation, avoiding damage caused by impacting the bucket to rocks.
