What is blow-moulding?
Blow moulding is when plastic granules are injected into a mould after being melted, and then compressed air is blown into the mould to hollow it out. This can make shapes like bins and bowls.

What is NNPB?
NNPB = Narrow Neck Press and Blow. This is a glass bottle forming process,wherein very light weight glass bottles are made compared to the traditional blow and blow process of making glass bottles. NNPB bottles are lighter by around 30% compared to Blow and Blow process,and the bottles produces have evenly distributed glass,and so stronger than blow and blow glass bottles. But this process requires hitech glass forming machinery,expensive mould items and very skilled labour. Most of the renowned glass bottle making companies are now making bottles using this technology.
What are the advantages in extrusion moulding?
it sound cool !
Why you use cold water in tire curing press?
Because the moulding process is conducted under high temperature. Cold-water curing 'freezes' the moulded tyre to it's current shape.

What are the main differences between injection molding and blow molding?
In injection moulding the polymer is moltern and 'injected' into a mould. in blow moulding the polymer is as a sheet or as a parison that is pushed into a mould by air. I guess the main difference is injection moulding fills the mould with solid parts where as blow moulding just creates a thin surface

Banter
What are the steps of extrusion moulding?
The process of Injection Moulding Cycle has the following 4 stages:- 1. Clamping- The multiple parts of the mould are securely clamped. 2. Injection- The raw plastic material, usually in the form of pellets, is fed into the machine. During this process, the pellets are melted by heat and pressure. The molten plastic is then injected into the mould by injection unit very quickly and the build-up of pressure packs and holds the material. 3. Cooling- The molten plastic that is inside the mould begins to cool as soon as it makes contact with the interior mould surfaces. As the plastic cools, it will solidify into the shape of the desired part. However, during cooling some shrinkage of the part may occur. The packing of material in the injection stage allows additional material to flow into the mould and reduce the amount of visible shrinkage. The mould can not be opened until the required cooling time has elapsed. 4. Ejection- After sufficient time has passed, the cooled part may be ejected from the mould. When the mould is opened, a mechanism is used to push the part out of the mould. Force must be applied to eject the part because during cooling the part shrinks and adheres to the mould.
Can PET be used in extrusion blow molding?
Hey there,Blow molding is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.- noizyoyster.com
