Carbide Ball Teeth

Carbide Ball Teeth, also known as carbide ball inserts, tungsten carbide ball teeth, or conical picks, are a specific type of wear part and cutting tool characterized by their hemispherical (ball-shaped) head made of tungsten carbide. They are primarily designed for robust impact, crushing, and grinding applications, rather than precise shearing or slicing. Their unique design allows them to transmit high point load forces into the material, making them ideal for breaking extremely hard and abrasive substances.

Composite Plate Substrat

A Composite Sheet Substrate refers to a base material, typically in sheet form, that is composed of two or more distinct physical or chemical phases combined to create a new material with superior properties compared to its individual components. In advanced industrial contexts, this often involves combining a tough, ductile matrix (like a metal or polymer) with a hard, reinforcing phase (like ceramic particles or fibers) to achieve a balance of strength, toughness, and other specific functional properties. These substrates are engineered to serve as a foundational platform for further processing or as a core structural component in demanding applications.
