How to Choose the Right Plastic For Your CNC Machining Project

If you have a custom machine shop in Pittsboro NC, then it is important for you to choose the right type of plastic. There are different types of plastic, and each has its advantages and disadvantages.


ABS is a general use plastic. It is often used in Pittsboro CNC machining because it is great for pre-molding and purpose prototyping. It also does not cost a lot of money. However, ABS does not have enough chemical resistance or good abrasion.


A local CNC machinist may opt to use Nylon because it is durable and strong. However, it can absorb moisture, which can cause it to swell.


Acrylic is also known as Luctie or Plexiglass. It is strong and resistant to scratches. However, acrylic can be brittle. That is why it is prone to shattering or cracking.


Delrin is a good option for a Pittsboro CNC machining job that requires a lot of friction and high stiffness. However, it can be hard to glue.


HPDE is short for high density polyethylene. It is great for electrical insulation, chemical resistance and slippery surface. However, it isn’t very strong.


Polycarbonate is one of the most durable forms of plastic there is. It is stiff and highly resistant. However, it is prone to scratches.
