Qiming Casting has the whole bimetallic wear solution to protect the excavator bucket. The wear package including Chocky Bars, Wear Buttons, Wear Bars, Heel Shroud, Lip Shroud, Wing Shroud, and Skid Bars will provide comprehensive wear protection on the weak points on the buckets. With the whole protection solution, the service life of the bucket could be multiplied and maintenance is significantly reduced.
Chocky bars, also known as chocky blocks or wear bars, are a type of wear-resistant material used in various industries to protect surfaces from abrasion and impact. These bars are particularly common in applications where materials experience sliding or impact wear. The name “chocky” is derived from their use in chutes and hoppers where materials often get stuck or “chocked.”
Chocky Bars are unique block products, which can be formed and welded onto flat or curved surfaces. Chocky Bars can be used on a range of fixed plant and mobile equipment such as buckets and chute liners.

A wear button is a type of wear-resistant material used in industrial applications to protect surfaces from abrasion, impact, and wear. Similar to chocky bars, wear buttons are typically made from a combination of a wear-resistant white iron alloy and a steel backing plate. The wear-resistant alloy provides excellent hardness and toughness, while the steel backing plate adds strength and facilitates easy attachment to the surface that needs protection.
The wear button gets its name from its button-like appearance. It is essentially a small, circular or slightly domed wear-resistant insert that is welded onto surfaces that are prone to wear and tear. The buttons are strategically placed on the equipment or machinery where wear is likely to occur, providing localized protection.
