Knife Head

Function of the Knife Head

The extruder cutting knife (knife head) is installed at the outlet of the extruder die and is responsible for cutting the product stream immediately after it exits the die into pellets of the required length. This component plays a critical role in determining the uniformity of pellet length, shape, and overall appearance of the feed pellets.

Machining of Knife Head at Tien Phat Mechanical

Machining knife heads at Tien Phat Mechanical is a highly technical process that requires exceptional precision, in-depth material knowledge, and extensive practical experience in extrusion technology. Operating directly at the die outlet, knife heads work under harsh conditions of high temperature, high humidity, and continuous friction. Therefore, the selected materials must ensure excellent wear resistance, heat resistance, and stable sharpness, tailored to each specific application in animal feed and aquatic feed extrusion machines.

Knife heads are precisely machined using CNC equipment to strictly meet technical drawings, ensuring dynamic balance and stable cutting performance during operation. The blades undergo controlled heat treatment and fine grinding processes, enhancing surface hardness, improving wear resistance, and significantly extending service life.

In addition, a strict quality control system is applied throughout the entire production process—from dimensional inspection, sharpness and hardness testing to assembly accuracy and actual operating performance—supported by advanced measuring and inspection equipment. This ensures that each knife head meets high standards of precision and durability before being delivered for use.

Thanks to the combination of advanced machinery and technology, long-standing experience, and deep understanding of real-world operating requirements, knife heads manufactured by Tien Phat Mechanical consistently deliver high performance, long service life, and reliable operation in continuous production environments.
