Is polycarbonate good for injection molding?
Also known as PC, polycarbonate is an adaptable thermoplastic that’s durable and pliable, able to be injection molded and thermoformed, depending on the project.
What are the properties of injection moulding?
Injection molding machines perform a wide range of mechanical movements with differing characteristics. Mold opening is a low-force high-speed movement, and mold closing a high-force low-speed movement. Plasticizing involves high torque and low rotational speed, while injection requires high force and medium speed.
What is the strongest injection molded plastic?
Polycarbonate (PC): Polycarbonate is a transparent thermoplastic that offers some of the strongest, most shatter-resistant construction available for plastic injection molded products.
At what temperature can you form polycarbonate?
350°F to 360°F.
Heating MAKROLON® Polycarbonate Sheet for vacuum forming requires heat penetration to achieve a 350°F to 360°F. The heat required will be higher for more complex shapes. When MAKROLON Polycarbonate Sheet reaches forming temperature, uniform “sag” occurs.
What makes polycarbonate strong?
What Makes Polycarbonate So Strong? The source of polycarbonate’s strength is its incredibly strong chemical structure. Its molecules possess tremendously strong bonds in high numbers, giving it its unique levels of resistance. Polycarbonate typically has a tensile strength of between 55–75 MPa (force per unit area).
What is mold in injection molding?
A mold is a hollow metal block into which molten plastic is injected to from a certain fixed shape. Then, the mold is opened after cooling process and the ejector rod of the injection molding machine pushes the ejector plate of the mold to further eject moldings.
What material is used in injection molding?
Injection Molding Materials
|Polypropylene||Thermoplastic polymer used for a wide number of applications.|
|Polyoxymethylene (POM)||Dimensionally stable thermoplastic with high stiffness and low friction.|
|Polycarbonate||Thermoplastic material with good temperature resistance and impact strength.|
