Deflashing Polycarbonate Molded Parts

Polycarbonate Material

Polycarbonate is a type of plastic that is known for its strength, transparency, and resistance to impact. It is a polymer, which means that it is made up of repeating units of a small molecule called a monomer. In the case of polycarbonate, the monomer is a compound called bisphenol A, which is linked together to form long chains of polycarbonate molecules.

Polycarbonate has a number of properties that make it useful in a wide range of applications. It is a strong and stiff material that is resistant to impact and can withstand high temperatures. It is also transparent, which makes it useful for applications where transparency is important, such as windows, glazing, and protective eyewear. In addition, polycarbonate is resistant to UV radiation and many chemicals, which makes it useful in outdoor applications and in industries where it may come into contact with chemicals.

Polycarbonate is commonly used in the construction industry for windows and skylights, as well as in the automotive and electronic industries for various parts and housing. It is also used in the medical field for devices such as IV bags and tubing, and in the sports industry for equipment such as hockey sticks and helmet visors. Polycarbonate is used to make a variety of industrial parts, such as gears, bearings, and rollers, because it is strong and has good wear resistance.

Molding Polycarbonate Parts

Molding polycarbonate is a process that involves heating the material and shaping it into a specific form using a mold. Polycarbonate is a strong, stiff, and transparent plastic that is widely used in a variety of applications due to its strength, transparency, and resistance to impact.

There are several methods that can be used to mold polycarbonate parts, including injection molding, blow molding, compression molding, rotational molding, and thermoforming. The specific method that is used will depend on the size, shape, and quantity of parts that need to be produced, as well as the equipment and resources that are available.

One of the main challenges of molding polycarbonate is that it has a high melting temperature and is prone to warping and shrinkage when cooled. This can make it difficult to achieve high-quality, consistent parts, especially for complex shapes. To address these challenges, it is important to carefully control the temperature and pressure during the molding process and to use high-quality molds that are properly designed and maintained.

Cryogenic Deflashing Polycarbonate

Cryogenic deflashing is a process that involves using low temperatures to remove excess material known as flash from polycarbonate molded parts. It can be used on polycarbonate among other materials to remove residual flash, which is the thin layer of material that is often present on the edges of molded parts. This deflashing process offers a consistent and repeatable way to remove flash from your molded polycarbonate parts

Cryogenic deflashing is typically performed using liquid nitrogen, which allows the parts to be cooled to low temperatures and then blasted with a fine media applied to remove the flash. This allows the flash to become brittle so that it is easily removed.
