Downsides, Nylon 6/6 will soak up moisture, triggering it to swell and lose some dimensional accuracy. It can likewise warp if there is a big quantity of uneven material removal throughout machining, due to internal tensions intrinsic in the product. Typical Applications, Nylon is most frequently discovered in medical devices, circuit board mounting hardware, vehicle engine compartment elements, and zip ties.

Acrylic, Overview, Acrylic, likewise called Plexiglass or Luctie, is the brand name for PMMA plastic. It is hard, with decent effect strength and scratch resistance, and can be quickly glued using acrylic cement. Advantages, It is well suited for any applications that need optical transparency or transparency, or as a less durable but more affordable alternative to polycarbonate.



Any machined surface areas on a piece of acrylic will lose their openness and take on a frosted, translucent appearance. Due to the fact that of this, is it generally a great concept to keep in mind if an acrylic part ought to be left at stock density to maintain openness or not. If transparency is required on a machined surface, it can be polished as an additional post processing action.


Delrin, Overview, Delrin is a particular brand name of acetal homopolymer (aka POM). It has a slippery, low friction surface, outstanding dimensional stability, and high stiffness. Benefits, Delrin is an excellent plastic for these or any other applications that will experience lots of friction, require tight tolerances, or require a high stiffness material.

The product also has internal stresses that make it susceptible to contorting in areas that are thin or have large quantities of asymmetric material elimination. Typical Applications, Delrin is commonly utilized in gears, bearings, bushings, and fasteners, or to make jigs and components for assembly.  This Piece Covers It Well , HDPE means high density polyethylene.


It is well suited for making plugs and seals, due to its chemical resistance and slipperiness, however is likewise a great choice for weight-sensitive or electrically delicate applications. Drawbacks, HDPE's primary disadvantage it its poor strength, especially in tension and flexing. Typical Applications, HDPE is frequently utilized in fluid applications, such as fuel tanks, plastic bottles, and fluid circulation pipes.
