PP CNC Machining

Polypropylene, PP by short, is lightweight plastic with phenomenal exhaustion resistance and toughness. These homes make it a prominent material for usage in a variety of applications across the automobile, product packaging, and customer product industries.

While CNC machining in polypropylene is tested as a result of its tendency to gall and melt, homopolymer polypropylene supplies a variety of benefits for CNC-machined components. Its slick surface makes it perfect for mechanical items like equipment and its fatigue resistance implies that slim attributes such as living hinges are easy to include right into layouts.

Cost-saving Design Tips

CNC machining in polypropylene can be affordable thanks to the low cost of the product. However, decreasing excessive machine and post-processing time is critical to keeping prices low. One method this can be accomplished is by keeping tolerances conventional for plastic and composite machining.


Yes, Polypropylene (PP) can withstand fairly heavy loads, despite being lightweight, and offers good fatigue strength. It also resists most solvents and chemicals, which makes it a suitable material for manufacturing laboratory equipment and containers for a variety of uses.

Polypropylene (PP) resists most solvents and chemicals, which makes it a wonderful material to manufacture laboratory equipment and containers for a variety of applications. PP also offers good fatigue strength.

The disadvantages of polypropylene are:

Its post-cooled resistance to adding coatings such as paint or ink.
If the fiber becomes too hot, there is a tendency to break.
PP is highly flammable and will melt when exposed to heat. It has a flash point of 260° Celsius.
It can often suffer from chain degradation leading to oxidation, which subsequently results in cracks and crazing.
It is prone to damage from UV light.
