Extrusion tools are essential components in the extrusion process, a manufacturing technique used to create objects of a fixed cross-sectional profile. These tools are responsible for shaping molten or pliable material as it is forced through a die. The primary extrusion tool is the die itself, which contains a precisely shaped opening that dictates the final cross-section of the extruded product. Dies are typically made from hardened tool steels or carbides to withstand the high pressures and temperatures involved.

Another critical component is the ram or screw, which provides the force necessary to push the material through the die. In direct extrusion, a ram pushes a heated billet, while in indirect extrusion, the die moves towards a stationary billet. In screw extrusion, a rotating screw continuously feeds and compresses the material. Ancillary tools may include preheating furnaces for the material, lubrication systems to reduce friction, and cooling or stretching equipment to control the properties of the extruded product. The selection and maintenance of these extrusion tools are crucial for achieving desired product quality, dimensional accuracy, and efficient production. Different materials and extrusion processes require specific tool designs and material compositions to ensure optimal performance.
