IBM vs ISBM:
\nInjection Blow Moulding vs Injection Stretch Blow Moulding<\/span><\/h1>\n

IBM (Injection Blow Moulding) and ISBM (Injection Stretch Blow Moulding) are two distinct blow moulding processes that are frequently confused by container buyers, brand packaging engineers and blow moulding machine specifiers. The key difference is mechanical: IBM inflates a preform using air pressure alone; ISBM first mechanically stretches the preform axially with a stretch rod, then inflates it. This single difference produces fundamentally different container properties, material compatibility, output economics and machine investment profiles.<\/p>\n

KEY PROCESS DIFFERENCE<\/p>\n

Stretch Rod<\/p>\n

ISBM inserts a mechanical stretch rod into the preform to elongate it axially before or during air blow inflation. IBM has no stretch rod \u2014 air pressure alone inflates the preform. This mechanical stretch in ISBM is the source of all process, material and property differences between IBM and ISBM<\/p>\n<\/div>\n

MAT\u00c9RIAU PRIMAIRE<\/p>\n

IBM: PP \u2022 ISBM: PET<\/p>\n

IBM processes PP, PCTG, PE, HDPE and other non-stretch-oriented polymers. ISBM processes PET (primary), PP (biaxially oriented), PLA, PC and other stretch-responsive materials. The material difference follows from the process: stretch orientation requires polymers that strain-harden under biaxial stretching, which PET does strongly and PP does moderately<\/p>\n<\/div>\n

CONTAINER APPLICATIONS<\/p>\n

IBM: Cosmetic \u2022 ISBM: Beverage<\/p>\n

IBM: cosmetic cream jars, lotion bottles, pharmaceutical bottles, wide-mouth containers, PP containers where monomaterial recyclability is required. ISBM: PET carbonated drink bottles, water bottles, edible oil bottles, large-format beverage containers where high axial strength and CO2 barrier are required<\/p>\n<\/div>\n

MACHINE TYPE (KOREA EVER-POWER)<\/p>\n

ZQ Series (IBM)<\/p>\n

Korea Ever-Power manufactures ZQ series IBM machines (ZQ40 through ZQ135 and ZQ60HE all-electric). Korea Ever-Power does not manufacture ISBM machines. ISBM machines for PET bottle production are manufactured by Sidel, Krones, Husky and Nissei ASB (for one-stage ISBM). ZQ IBM machines produce PP and PCTG cosmetic, pharmaceutical and personal care containers<\/p>\n<\/div>\n<\/div>\n<\/div>\n
