New Applications of Blow Molding Technology
Coextrusion Blow Molding of Large PartsCoextrusion is used extensively in small bottles and containers, but increasingly also for large blow molded parts (18.92 liters or 5 gallons and larger). Its growth, however, is very healthy and will accelerate in the coming years because of the need for recycling of plastic and the application of this [...]
Introduction to Equipments of blow molding
There are six kinds of PET Blow Molding Machineries: Single Stage Blow Molding Machine Two Stage Blow Molding Machine Integrated Two Stage Blow Molding Machine PET Blow Molding Machines Automatic PET blow molding machine Semi Automatic PET blow molding machine Single Stage Blow Molding Machine […]
Introduction to Stretch blow molding
With the commercial introduction of containers, stretch blow molding became a common term in the blow molding industry. […]
Introduction to Injection blow molding
The injection molding phase consists of injection molding a thermoplastic material into a hollow, tube-shaped article called a preform. The preform is transferred on a metal shank, called the core rod, into a blow mold. […]
Introduction to Extrusion blow molding
In extrusion blow molding (EBM), plastic is melted and extruded into a hollow tube (a parison). Blow molding is the forming of a hollow object by “blowing” a thermoplastic molten tube called a parison in the shape of a mold cavity. […]
Introduction to History of blow molding
The process of using air to blow hot material was first used by the Syrians. The method is attributed to Syrian glass workers in the first century BC, […]
What is Blow molding?
Blow molding, also known as blow forming, is a manufacturing process by which hollow plastic parts are formed. It is a process used to produce hollow objects from thermoplastic.In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding. […]
Introduction to Transfer molding
Transfer molding, like compression molding, is a process where the amount of molding material (usually a thermoset plastic) is measured and inserted before the molding takes place. […]
Introduction to Compression molding
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the [...]
