Plastic Injection Molding vs. 3D Printing Plastic injection molding generally entails making plastic containers using the pelleted or granular plastic resins. For PET bottles, stretch blow molding machine is normally used to achieve the same. In injection molding variety of materials are used, these include the polystyrene, polycarbonate, polypropylene, polyvinyl chloride and others. There are […]

Reasons why PET bottles are widely used

Reasons why PET bottles are widely used PET material also known as PETE is an ideal polyester material for making injection molded parts including bottles and jars. PET is made of elements that have special grades making it good for wide range of application. It is composed of long-chain molecules having repeated units that make […]

Why a two-stage method is recommended for making PET bottles

Why a two-stage method is recommended for making PET bottles Why PET plastics are molded using high temperatures compared to another form of plastics. This is because PET materials have a high melting point of about 270 °C which can sustain high-temperature injection molding. Apart from melting point, PET products are preferred due to their […]

Shrink wrapping or package wrapping is a process in which an item or a group of products is wrapped in an envelope or sleeve of plastic film and then passed through the heat to shrink and firmly fit to enclose the products.  The most common materials used in shrink wrapping […]

Blow Molding

Blow molding, also known as BrE molding, is a manufacturing process where hollow plastics are inflated with hot thermoplastic perform to produce a bottle or a container that conforms to the mold cavity. This process is also used in glass bottles production. Blow molding usually begins by melting down the plastic material into a parison. […]
