Polycarbonate Machining Complete Guide


Polycarbonate(PC) has many functions as a safe and non-toxic plastic material, and its existence has advanced the development of industry with a high status.


The polycarbonate machining process means that it is CNC turning, cut, drilled, milling and ground. If you have high precision requirements for polycarbonate parts, then CNC polycarbonate is particularly suitable for your project.

What is Polycarbonate


Polycarbonate is a high strength and transparent thermoplastic resin material. As the fastest growing engineering plastic, Polycarbonate materials has the best impact resistance of any plastic.



Advantages of Polycarbonate Material


oem parts manufacturer

Chemical resistance

PEEK is chemically stable and resistant to strong acids, bases, organic solvents and oxidizers.

oem parts manufacturer

Fatigue resistance

Fatigue resistance is superior, is the ideal structural stress material, PEEL parts after 30 years of long-term stress can maintain its shape and performance.

oem parts manufacturer

High purity

High purity, can be used in the electronic semiconductor field and medical treatment, and can replace titanium metal for human implant materials

oem parts manufacturer

Radiation resistance

One of the best polymers to withstand gamma radiation, with doses up to 10 Rad. peeK can solve the problem of reduced plastic elongation due to high energy radiation.

Polycarbonate Applications


Industrial Machinery: polycarbonate material has many advantages such as light weight, low running noise, corrosion resistance, etc., and it has the characteristics of low manufacturing cost and flexible design. Through CNC machining, 3D printing, molding and other processes can be used to manufacture a variety of gears, racks, worm wheels, worm gears, bearings, cams, bolts, levers, crankshafts, ratchets, as well as some mechanical equipment shells, covers and frames and other transparent parts.


Automotive Manufacturing: automobile manufacturing industry: polycarbonate has good impact resistance, thermal distortion resistance, and good weather resistance, high hardness, so it is suitable for the production of various parts of cars and light trucks, which are mainly concentrated in lighting systems, instrument panels, heating panels, defrosters and bumpers made of polycarbonate alloy, etc.




Aviation and Aerospace: with the rapid development of aviation and aerospace technology, the requirements for various components in aircraft and drones are increasing, making the application of PC in this field is also increasing. According to statistics, only one Boeing-type aircraft used polycarbonate parts up to 2,500, single aircraft consumption of polycarbonate about 2 tons.


Medical Devices: since polycarbonate products can withstand disinfection by steam, detergents, heating and large doses of radiation without yellowing and physical property degradation, they are widely used in artificial kidney hemodialysis equipment and other medical devices that need to operate under transparent and intuitive conditions and require repeated disinfection, such as the production of high-pressure syringes, surgical masks, disposable dental appliances, blood separators, etc.

Polycarbonate vs Acrylic


Both are transparent plastic, in the same thickness, the same raw material particles, Acrylic than Polycarbonate light transmission rate is 2-3% higher, are close to 90%, the naked eye is not easy to distinguish. But the other performance differences between the two is still relatively large, after all, is 2 kinds of plastic material.

1、Heat resistance, temperature resistance, weather resistance

Acrylic reaches 70 degrees is easy to soften, while polycarbonate is 120 degrees, so polycarbonate is more resistant to heat and heat, working temperature applications more widely.

2、Impact resistance, smash resistance, strength resistance index

The same thickness, polycarbonate impact strength is acrylic 30-50 times, 6 mm polycarbonate sheet is bulletproof material, 3 mm polycarbonate sheet ordinary adults with a hammer can not be broken.

3、Flame-resistant, fire-resistant

Polycarbonate is a flame retardant material, belonging to the B class flame retardant (international UL94-V2 grade), one of the self-extinguishing plastic, not easy to burn, while acrylic is not flame retardant.

Polycarbonate vs PVC


1、Different performance

PVC is a colorless and transparent plastic like polycarbonate, but PVC is softer than polycarbonate material and less transparent than polycarbonate. The density of polycarbonate is less than that of PVC, and the light transmission function is better than that of PVC board, but the continuous use temperature is higher than that of PVC material.

2、Different uses

Because of the difference of various properties of materials, PVC materials are mainly used as daily plastic products and polycarbonate materials are mainly used as engineering plastic products. PVC materials are often used as plastic doors and windows, water pipes, molds, plates, stair handrails, and plastic toys. PC material can be used as window and door glass, widely used in banks, embassies and public places for protective windows, for aircraft hatches, lighting equipment, industrial safety stalls and bulletproof glass.

3.Different price

PVC is much cheaper, usually only one half to one quarter of the price of polycarbonate.
