introduction
Delrin 150 in CNC Machining
Delrin 150 is a specific grade of Delrin that offers enhanced mechanical properties compared to the standard grade.
Delrin, also known as POM (polyoxymethylene), is a high-performance engineering thermoplastic widely used in CNC machining. Delrin 150 has a low coefficient of friction, excellent dimensional stability, high stiffness, and good wear resistance. It is a strong plastic suitable for extrusion processes. It remains stable at high temperatures, minimizes residue buildup, and improves crystallization for denser structures. It has minimal warping and resistance to deformation.
Machining Delrin generally requires higher cutting speeds and lower feeds compared to metals. Delrin has good machinability without the need for coolant in many cases. However, using air or a mist coolant can help in chip evacuation and cooling during machining. Lubrication can improve tool life and surface finish. Dry cutting is also feasible, depending on the machining parameters. Delrin has low moisture absorption and minimizes the need for post-machining drying processes.

TECHNOLOGY OVERVIEW
Basic Knowledge of Delrin 150
What is Delrin 150?
Delrin 150 is an acetal homopolymer that offers a balanced set of properties, combining characteristics of both metal and plastic. This material can be an ideal replacement for metal. It has low moisture absorption, high tensile strength, resistance to deformation (creep resistance), and overall durability.
Additionally, Delrin has chemical resistance to hydrocarbons, solvents, and natural chemicals, which is why it is good for components exposed to wet environments, such as pump and valve parts.
Delrin is easy to process with minimal odor, reducing issues like mold deposit and machine corrosion. It has a wide processing temperature range and high productivity, leading to cost savings in manufacturing.
