When it comes to creating custom parts and prototypes, technology has moved CNC plastic machining to the forefront. This machining technique is widely used because it makes a strong, light, and inexpensive product. The cost of manufacturing items is reasonable compared to metal because the product is very workable with the right tools.
The Process
To machine this material, shops need mills, turns, and drills. The finished pieces will need to be sanded or punched. The tools required to do the work are often made of carbide.
The machinist must configure the angles of the bits and punches for plastic. If they are not, they tend to chip away at the material. The motors behind the operation are working fast too. The bits need to move quickly on the plastic, much quicker than they do on aluminum and other metals.
Even though this plastic is strong, the machinist needs to treat it properly and protect the surface with padding and special clamps. The clamps used on metal may damage or mar this material.
Prototype
Many operations opt for plastic prototypes because they can prove concept and fit. The first-run components can show design flaws. The machinist can use the existing dimensions, make the necessary adjustments, and get the newly configured one made.
The customer can quickly go through pieces until they find the exact one and then order bulk bundles or move onto metal parts. It is cost-effective to start with plastic, even if the part will eventually be metal. For more information on CNC plastic machining, contact JBC Machine, Inc.
