What is CNC Machining Polypropylene (PP)?

Polypropylene, or PP for short refers to a family of semi-rigid thermoplastics that are white and odorless. Polypropylene (PP) is a BPA-free, lightweight plastic with exceptional fatigue resistance and toughness. They also possess excellent physical properties such as high strength at low temperature, good resistance against chemical exposure withstanding heat up to 200℃ (392 °F). Polymers made from these materials have been rapidly adopted by sectors including automotive manufacturing,packing,machinery, automobiles, electronic appliances, construction, textiles, agriculture, due their combination set of desirable performance characteristics . CNC machining Polypropylene (PP) is a process that applies computer-controlled digital technology to remove the extra material and complete any necessary cutting, turning or milling. This can be done with machine tools depending on what's needed for your specific programmings before getting an end product from Polypropylene (PP) in their final form.

What are the benefits of CNC Machining Polypropylene (PP)?

PP's main advantage is its outstanding processing performance. It can be injection molding or CNC machined, such as PP capsules.PP is always CNC machined from sheet material. CNC machining could make prototypes and small batch PP parts with high precision tolerances.Polypropylene (PP) more suitable for CNC machining, turning, milling or drilling. CNC machining method could makes Polypropylene (PP) with very tight tolerances.Blow are some characteristics for Polypropylene (PP) in CNC machining:

Chemical resistance: PP will not react in any acids,so it could make liquids. Elasticity and toughness:

PP is generally considered to be a tough material because it can withstand deformation within certain limits and does not break apart when stressed.

Fatigue resistance: PP retains its shape after a lot of twisting and bending test. This feature is particularly valuable for making living hinges.

Insulation: PP material is a high resistance and insulating material.

Justin, CEO of a lighting company

I inspected the top two pieces of all five boxes. Everything is beautiful! BEAUTIFUL! You remove so much stress from my shoulders. I know that when we pay you to manufacture a product, it will be made perfectly. The glass bead blasting and anodizing is always beautiful. I am so very happy! You make it easier for us to run our business. There is no trouble! With most factories, I have a moment of fear before I open their boxes. Will the components be made correctly? Do they care about quality? It is often a war. And Dennis has to fight the war, treating most factories like small children! But, not your company. You’re company is world-class. You make beautiful components!Thank you very much for your hard work. We will work together for many lifetimes!

David, General manager for a family owned business

I’ve been working with Chinese manufacturers since 2004 and had some really unfortunate partnerships until 2012 when we partnered with Worthy Hardware. At first,we only gave them small orders to test and make the start. However,their response speed was very fast ,and their engineers help us improved our designs more simple, this helped us reduce a lot of cost.Our cooperate is more and more stable! We trust Worthy Hardware always ,very responsible. Your guys are great! .Worthy Hardware is by far my favorite, because of the way they handle business and the quality of what they make.If you are from USA and would like to know more about Worthy Hardware,i would be very happy to be as an endorsement.


CNC Machining PP FAQ

1. What are the applications for CNC machining Polypropylene (PP)?

The typical applications for CNC machining Polypropylene (PP) is in automotive industry, such as the fenders, ventilation ducts, fans.
Meanwhile, as a new type of polymer material.PE is made to sheets, pipes and rods, they are widely used in every corner of production and life, and gradually replaced traditional plastics.

CNC machining Polypropylene (PP) is also used for dishwasher door gaskets, dryer ventilation ducts, washing machine frames and covers, refrigerator door gaskets.

2. What should we pay attention when processing Polypropylene (PP) in CNC machining?

PP is used for CNC processing in sheet form. When making prototypes of a small number of PP parts, we usually perform CNC machining on them. PP has a low annealing temperature, which means it is easily deformed by heat, so it requires a high level of skill to cut accurately. There are some machining tips share with you.
①We must evaluate the shape of the work-pieces, then it is better to use more strength PP material, but this will increase the material cost.
②In the annealing process, Polypropylene (PP) is exposed to a furnace at very low temperatures in order to reduce its tendency of becoming brittle under pressure. This makes PP perfect for use with high-precision CNC machining as it does not generate any stresses when heated up from being worked on by mechanical tools or human hands.
