What is CNC Machining Polycarbonate(PC)?
Polycarbonate or PC is one of the most widely used thermoplastic materials. Below chart of the properties. CNC machining PC 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 PC in their final form.

What are the benefits of CNC Machining Polycarbonate (PC)?
Polycarbonate or PC could be made by injection tools at a very cheap price. However, CNC machining is another method to produce PC without expensive tools and fast production with precision tolerances. Below are the material properties suitable for CNC machining.
1) Mechanical properties: high strength and elastic coefficient, high impact strength, good fatigue resistance, good dimensional stability, small creep (very little change under high-temperature conditions), high transparency, and free coloring.
2) Heat resistance to aging: wide range of use temperature, enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term aging is also very good).
3) Solvent resistance: no stress cracking.
4) Stability to water: easy to decompose under high temperature in contact with water (caution is needed when using in high temperature and high humidity environment)
5) Insulation performance: excellent (moisture, high temperature can also maintain the electrical properties of stable, is the ideal material for the manufacture of electronic and electrical parts).
6) Dielectric coefficient: 3.0-3.2.
7) Arc resistance: 120s.
8) Molding process-ability: common equipment injection or extrusion.

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 PC FAQ
1.How to improve the deformation for CNC machining PC?
As a popular CNC machined plastic material, Polycarbonate or PC could be well CNC machined, CNC turned, CNC milled, CNC drilled, however, the melting point of PC is only about 120 degrees, So the production method is different with aluminum, steel, and other metals material, otherwise, they will be easily deformed in the production, here we would like to share 2 tips to avoid the deformation. Annealing Polycarbonate PC has excellent impact strength; small creep and good dimensional stability, higher heat resistance. However, PC materials have low fatigue strength, are prone to stress cracking, have a small allowable long-term use load, and have poor wear resistance. Therefore, annealing is crucial if you want a quality, precision machined part out of the stock shape. The annealing process at Worthy Hardware greatly reduces the chances of these stresses occurring from the heat generated during machining PC. Meanwhile, we have improved the CNC processing technology to avoid cracking, and the light transmittance reaches 80%, which is close to plexiglass. We provide many years of PC processing CNC lathe processing services, please send us 2D drawings or 3D drawings, so that we can evaluate and quote for you. Hope we can become your trusted supplier of CNC machining. Machining Polycarbonate Polycarbonate rods and plates are easy to machine and have excellent dimensional stability. We recommend non-aromatic, water-soluble coolants because they are most suitable for ideal surface finishes and close tolerances. These include pressurized air and spray mists. Coolants have the additional benefit of extending tool life as well.
2. What are the applications for CNC machining PC?
Polycarbonate or PC, as one of the popular engineering plastics, is widely used for glass assembly industry, automobile industry, and electronics industry, they could be CNC machined to connectors, housings, and covers, boxes, insulators, gaskets, lenses, glass windows, seals, electrical equipment, optical storage media, safety helmets, face shields, dashboards, signs and displays, packaging materials, wheels, rollers, aircraft parts, Car parts, etc. Medical industry Medical equipment requires transparent parts to observe the testing results, then PC or PMMA would be the best plastic material. Therefore, custom CNC machined PC parts are often used for easy observation. More, PC material has good toughness, Therefore, precision CNC PC parts can be well used in medical applications. Food industry 25 years of experience in CNC processing has allowed us to accumulate a wealth of information applicable for food industry applications, such as PC and PEK. This requires tight tolerances for the CNC machining process. Aerospace Field With the rapid development of aviation and aerospace technology, the application for CNC precision PC parts increased a lot. According to statistics, there are 2500 polycarbonate components used on a Boeing aircraft.CNC machined PC parts with tight tolerance and very smooth surface could be helpful for aviation. And make the airplanes safer and long-life used.
