CNC Machining pc Parts
PC CNC machining is a cost-effective method of cutting parts into bespoke shapes without the need for expensive tooling, and is suitable for prototypes, jigs and fixtures, as well as small batch production
PC Description
Polycarbonate (PC) is an amorphous, tasteless, odorless, non-toxic and transparent thermoplastic polymer with a high degree of dimensional stability, good insulation, heat resistance and non-toxicity. It has a high glass temperature, low water absorption, low shrinkage, high dimensional accuracy, light stabilization, and good weather resistance. These characteristics make polycarbonate a widely used material in electronics, construction, automotive and other fields.
CNC Machining PC Applications
Mechanical properties of PC
Polycarbonate is used in a variety of application scenarios where high strength and durability are required due to its excellent mechanical properties, including tensile strength, modulus of elasticity, impact strength, and yield strength.
Tensile Strength
Polycarbonate has a high tensile strength, usually between 60~70MPa, which shows its excellent rigidity and tensile properties.
Modulus of Elasticity
PC has a modulus of elasticity between 2200~2300MPa, which means it has good elastic recovery.
Impact Strength
The impact strength of polycarbonate is excellent, and it is known to have the highest impact toughness of any general thermoplastic. Its notched impact strength reaches 44kj/mz, showing its excellent impact resistance.
Yield Strength
The yield strength of PC is usually between 50 and 100 MPa, which is higher than some commonly used engineering plastics such as polypropylene and polyethylene. Meanwhile, its elongation at break is high, up to 15~100%.
