What is a Polycarbonate (PC) Injection Moulding?

Polycarbonates (PC) is an amorphous thermoplastic. These polymers allow transmission of light; like as in a glass. An important feature is that they can be heated to their melting point, cooled and heated again without degrading itself. As PC can liquify, you can undertake injection moulding. They are resistant to heat and can be used with flame retardant materials also, the molding parts made in Polycarbonate which we called Polycarbonate injection moulding.

Uses of Polycarbonate (PC)

They are an absolute necessity when there is you need to impact resistance and transparency. PC (Polycarbonate)
can be used across multiple industries. They are primarily used in different medical devices, digital compact disks, protective gear, eyewear, and much more.
It is finding use with security agencies for mob control and finds its way into materials for protective visors and riot shields.
PC (Polycarbonate) finds use in your car. Being flexible and heat resistant, PC (Polycarbonate) is located in the internal focal points; radiator flame broils, entryway handles, and front light bezels.
Polycarbonate is also used in making nurseries and greenhouses. It is UV resistant, allowing in the sun rays but not allowing the UV rays.

What is PC Injection Molding?

It is a manufacturing process to produce objects by inserting the molten PC (Polycarbonate) into a mould. Usually, the melt temperature for PC material is between 270-320 degrees Celsius. It may decompose at high temperatures and cause defects like bubbles, black spots, etc. Typically, the injection pressure is controlled between 80 and 120 MPa.

Mould release agents should not be applied in polycarbonate moulds during this activity. The application of recycled materials cannot be more than three times, with application quantity limited at around 20%. or no recycled material for the high polishing injection molding parts.
It can be used in the following:
• Medical devices and labware
• Electrical and electronic components
• Enclosures
• Industrial parts
• Lighting
• Lenses

Benefits of PC Injection Molding

The benefits arise from the type of material that is moulded to give the end-product. The benefits of polyurethane molding come from the characteristics of polycarbonates that are used in the process.
Easy to make. PC is lightweight but durable making installation so easy. You can even cut them with scissors, if necessary.
Versatile. You can be creative with the structures. You can easily shape igloos out of it. Go ahead with those fancy shapes in your mind.
Resistant to impact. You are worried about breakage. The material can resist rain, hail, and storms. It is resistant to flames and does not emit toxic gases when on fire.
Protects against harmful UV. They keep out the harmful radiation. They do not let the harmful rays into the glasshouses that are made of these materials.
Meager costs. These materials are easy to carry and handle. You do not have to bear high handling costs and labor.

Disadvantages of Polycarbonate injection molding.

Toxicity. They are known to release Bisphenol A (BPA) during degradation. You need to make them BPA-free.
Chemical resistance. It has sensitive to chemicals. It deteriorates when exposed to organic solvents. They are very sensitive to abrasive cleaners, cleaning products, and solutions.
Durability. It is prone to absorb odors and stress cracking.
Flow marks. If you are making high polishing plastic injection molding parts or transparent injection molding parts by use Polycarbonate, the flow mark could the number one important issue that you need to prevent in advance, as professional plastic mold company and expert in this type of material, gate design and cooling design is the most important thing to solve those issue.
