Can you CNC Delrin?
Advantages of machining Delrin Delrin is a popular engineering thermoplastic for CNC machining, both because of its material properties and its machinability. Its main advantages are: Machinability: Delrin is free-cutting plastic with excellent dimensional stability.
Is Delrin easy to machine?
It’s true that Delrin is an easy material to work with in terms of machining. It is a very stable material, which makes precise, tight tolerances easier to achieve for this thermoplastic. While machining, keep in mind that Delrin is sensitive to heat at or above 250 °F (121°C).
Does Delrin warp when machined?
Due to the composition of Delrin and temperatures from machining, it is highly susceptible to warping on large, flat parts or where there are thin walls. We recommend avoiding thin walls; if you need thin walls, use fasteners to clamp down your design.
Is Delrin plastic machinable?
Delrin® plastic also exhibits excellent wear properties in both wet and dry environments, making one of the more versatile engineering plastics available. This material offers excellent machinability, making it ideal for parts that require intricate geometries and/or tight tolerances.
Is Delrin harder than aluminum?
Is Delrin Stronger Than Aluminum? In purely technical terms, aluminum is far stronger than Delrin, but depending on the application, Delrin parts can substitute certain aluminum parts.
Is acetal the same as Delrin?
Delrin is a type of acetal homopolymer and therefore generally interchangeable with others of the same class. This means that Delrin still offers the same core benefits of general acetal plastics, such as: Excellent dimensional stability. Friction, fatigue, and abrasion resistance.
Which is harder nylon or Delrin?
Is Delrin stronger than nylon? While both materials are strong and durable, nylon has a higher tensile strength of 12,000 psi than Delrin with 10,000 psi.
Is Delrin as strong as steel?
Delrin plastic works as an excellent replacement for metal because of its high-tensile strength, low-friction and high-wear resistance, creep and warp resistance, and overall durability and toughness.
Can Delrin be injection molded?
Delrin® Polyoxymethylene (POM) Injection Molding Applications. Delrin® plastic parts that are manufactured through the injection molding process can be used for a wide range of applications over a spectrum of industries.
Can Delrin be heated and bent?
Yes, Delrin can be heated and bent but you should be careful not to heat it too close to its melting point where it will turn into a liquid.
What is better than Delrin?
Acetal has a better resistance to the effects of hot water and strong caustic solutions with a high pH value when compared to Delrin®. This makes Acetal a better choice for parts and materials handling applications involving the use of strong base chemicals.
What is harder than Delrin?
Is Delrin safe to laser cut?
Trotec and Universal say Delrin is safe to cut as long as you use an air assist and have a good filtration system. Although, some schools have banned laser cutting Delrin because it is known to emit Benzene which is a carcinogen.
Is Delrin stronger than ABS?
Delrin (DuPont’s brand of acetal) and ABS are both plastics. Delrin is referred to as an “engineering” plastic because it is stronger and more resistant to distortion under load. ABS is “commodity” plastic because it is cheaper and easier to mold, however because of it’s flexibility, is relatively hard to break.
Is Delrin cast or extruded?
Delrin® 150 is a high viscosity acetal homopolymer for extrusion processes.
Does acetone dissolve Delrin?

What temperature does Delrin soften?
Delrin AF Blend
|Coefficient of Thermal Expansion I to Laminates||E-831 (TMA)||5.0|
|Heat Deflection Temperature 264 psi||D648||244|
Can you laser cut Delrin?
Delrin® Overview Laser cutting Delrin® with a 10.6 micron wavelength CO2 laser produces clean cuts with smooth edges. Laser engraving Delrin® with a 10.6 micron wavelength CO2 laser can produce a high degree of detail and relief. A 1.06 micron wavelength Fiber laser can be used to laser mark Delrin® in certain cases.
Can Delrin be 3D printed?
Delrin is a 3D printing material with excellent resistance to wear, is an ideal material for such parts and functional prototypes. Another property that a 3D printing material should have for making parts and functional prototypes like gears and bearings is the material’s coefficient of friction.
