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 [...]
How to do a good mold Cleaning?
The type of fouling (chemical make-up and physical characteristics) or residue the molding process leaves behind on your tooling will help determine your cleaning requirements. Many resins contain stabilizers, […]
What is The Cleaning Culture in mold cleaning?
Mold cleaning is a process where major maintenance bottlenecks often occur because molds are pulled faster than they can be cleaned and made production-ready. I have visited plants where molds waiting to be cleaned line hallways and toolrooms, taking up valuable bench space. […]
How to create a repair plan for mold
Creating a repair plan for some companies usually means setting a mold on a repair technician’s bench with instructions such as “mold flashing, fix it.” Other companies might have a log or notebook that follows the mold, which the technician must decipher and then decide what to fix. […]
