What is injection molding and how does it work?
Injection molding is a forming process using molds. Materials such as synthetic resins (plastics) are heated and melted, and then sent to the mold where they are cooled to form the designed shape. Due to the resemblance to the process of injecting fluids using a syringe, this process is called injection molding.
What is the temperature of COC in injection molding?
Injection molding grades of COC from Ticona have a glass-transition temperature (Tg) between 70 and 185 C (158 to 365 F). As a result, their heat-deflection temperature (HDT) ranges from 75 to 170 C (167 to 338 F). Grades with Tg above about 140 C (284 F) have a flexural modulus in the vicinity of 500,000 psi and elongation at break of 3% to 4%.
What are the most common injection molding defects?
Injection molding defects can often originate from the material itself or how the manufacturer stores and handles the material prior to the production process. These defects can range from minor aesthetic issues to compromised strength of the finished component.
What is an injection molding jetting deformation?
Jetting refers to a kind of deformation in a molded component that can occur when there’s an initial “jet” of molten material injected into the mold cavity that starts to solidify before the cavity is filled. Jetting often appears as a squiggly line in the surface of the finished component, typically leading from the initial gate of injection.

What is the science behind Panadol?
The science behind Panadol. Prostaglandins are the chemicals which signal pain and inflammation in the brain. Paracetamol, the active ingredient in Panadol, works by blocking these p rostaglandins. It’s also gentle on the stomach and may be a suitable choice in patients for whom non-steroidal anti-inflammatories are not appropriate.
