Machining Different Plastics


Delrin is supplied in sheets and bars for the purpose of milling and turning and supplied in granular form for melting and placing in molds. It has excellent dimensional stability and is easy to cut to very low tolerances. It is high strength and is resistant to chemicals. Delrin is an excellent dielectric. It can be difficult to use adhesives with Delrin, however, but in our experience, it is possible to manufacture complete parts from a single mold and by using an intelligent approach to CNC machining the material.


Ultem is a high-performance thermoplastic that has excellent heat and flame resistance. It is supplied in the form of rods, sheets, tube, or film. Glass-reinforced Ultem requires coolant to machine, as well as hardened metal tooling. Ultem is a high-performance plastic that is stiff, strong, and relatively easy to machine. Some grades of Ultem are more difficult to machine because of their stiffness—specifically glass reinforced Ultem—but Jaco Products has the experience, knowledge, and equipment to tackle any Ultem project.


PEEK can be used as a reliable alternative for metals because of its stiffness, chemical resistance, low moisture absorption, and resistance to biodegradation. PEEK requires annealing before machining but can be machined to a high accuracy to very tight tolerances. You can find PEEK in aerospace, automotive, chemical, electronics, energy, and healthcare industries.


Nylon can be difficult to machine because it deforms easily from being held in position but offers extremely tight tolerances and high strength and dimensional stability. Jaco Products has plenty of experience machining nylon and we are happy to work with this material to produce your part.

For instance, sawing is ideal for straight cuts on thicker acrylic sheets, while laser cutting offers precision for intricate designs.

Drilling and milling acrylic can be done using standard woodworking tools. It’s important to use sharp drill bits and low drilling speeds to avoid cracking or shattering the acrylic. Cooling the acrylic with water or lubricating oil can help prevent overheating during drilling and milling operations.

Acrylic can be bent using heat or cold bending techniques. Heat bending involves heating the acrylic sheet until it becomes pliable and then bending it to the desired shape. Cold bending, on the other hand, is suitable for thinner acrylic sheets and involves scoring the acrylic along the bend line before bending it manually.
