CNC Plastic Machining: Factors And Benefits

by | Jan 12, 2018 | Machine

With the use of plastic components continuing to grow, it is becoming increasingly difficult for many fabrication and machine shops to ignore it. While some will continue to specialize in metal, others will see the benefits of including CNC plastic machining in their arsenal. This can prove to be advantageous for the machine shop, although, like any form of machining, it is imperative to consider the factors that will affect choosing the right plastic.

Factors to Consider

Plastic is a generic term. It embraces all types that fall within this category of material. However, not all plastics are the same. Always remember this when looking at producing a component from this material. Other factors to note are:

Heat and chemical sensitivity

Specific techniques required to hold workpieces in place without exerting excessive pressure

Routing remains the preferred method of removing material. However, issues can occur if the process is too slow or inefficient

It is important machinists select the right equipment. Combining proper tools with the right plastic helps to ensure the outcome of the procedure.

Advantages of CNC Plastic Machining

Using plastic instead of metal does offer certain advantages. Many of them are economic; others are functional.


Chemical, weather, and dent resistant

Transportation/shipping cost reductions due to material weight

Results in a longer tool life at machine shops

Environmentally friendly with material recyclability and less waste

Overall, plastic machining, especially when it involves sophisticated CNC equipment, provides machine shops, fabricators, and manufacturers with several benefits.

CNC Plastic Machining

Plastic is an integrated and even integral part of today’s world. Whether you are a machinist, consumer or manufacturer, plastic affects how you work and live. More and more machine shops are utilizing plastic to produce components for diverse industries. They see CNC plastic machining as one further way they can increase their market share while continuing to provide quality and precision work for their customers.
