Blow Moulding Machines
Extrusion, injection and stretch blow moulding for bottles, jars and jerrycans — ready for inline coding.
Also called bottle blowing machines, EBM, IBM and PET stretch blow moulders.
What these machines do
Making containers next to the filling line removes freight on empty bottles. This range covers extrusion blow moulding for HDPE and PP, stretch blow moulding for PET, and injection blow moulding for small precision containers.
In extrusion blow moulding a tube of molten plastic — the parison — is captured by a mould and inflated. Stretch blow moulding reheats an injection-moulded PET preform, stretches it with a rod and blows it at high pressure, giving a strong, clear bottle. Injection blow moulding forms the neck by injection first, then blows the body, producing scrap-free containers with accurate necks.
Engravics offers 4 models of blow moulding machines: 5 litre extrusion blow moulding machine (BM-E5), jerry can blow moulding machine (BM-E30), PET bottle blowing machine (BM-S4), injection blow moulding machine (BM-I40). Machines are supplied and supported from Gurugram, Delhi NCR, to customers across India.

Process sequence
Plasticise
Resin is melted in the extruder, or preforms are reheated.
Form
A parison is extruded or the preform is transferred to the mould.
Blow
Compressed air inflates the plastic against the cooled mould.
Cool & eject
The container sets, the mould opens and the part is removed.
Trim & test
Flash is removed and bottles are leak-tested and coded.
