About the Material

Chemical-Resistant PVC (Polyvinyl Chloride) is a great choice for designs requiring electrical insulation. Chemical-Resistant PVC also offers terrific resistance to alkalies and acids, which makes it the ideal choice for applications related to chemical-processing and tank/valve components.

Material Finish

PVC has an opaque, gray finish when machined. It has a smooth, matte appearance post machining and can be machined to a variety of surface roughnesses.

Design Recommendations

Min Wall Thickness

0.5 mm (0.02 in)

Min End Mill Size

0.8 mm (0.03 in)

Min Drill Size

0.5 mm (0.02 in)

Max Part Size

1200 x 500 x 152 mm [x,y,z] (mill) 152 x 394 mm [d,h] (lathe)

Undercuts

Square profile, full radius, dovetail profiles

Radii : Depth

Depth must not exceed 12x drill bit diameter. For end mills, depth must not exceed 10x tool diameter.

Cost Saving Tip

To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.

Vapor Polishing Versus Manual Polishing Plastics: Vaporizing the Mystery

Have you dismissed the idea of CNC machining a plastic part because you’re worried about the time, dexterity, and patience required to hand-sand the part? Still, there’s something to be said for the satisfaction of a pristine surface after removing the imperfections with a piece of sandpaper. If you’re looking for ways to smooth CNC […]
