The injection moulding machine industry spans several distinct segments — general injection moulding for solid plastic parts, and specialised one-step injection stretch blow moulding (ISBM) for finished hollow containers. The largest companies in each segment differ significantly. This article covers both, with a focus on ISBM machine suppliers for buyers whose goal is producing finished PET or PP bottles rather than solid plastic components.

Two Distinct Markets: General IM vs ISBM

When people ask about the largest injection moulding company in the world, the answer depends entirely on which segment they mean. General injection moulding — producing solid plastic parts such as automotive components, electronic housings, caps, closures, and consumer goods — is dominated by large multinational machine builders. One-step ISBM — producing finished PET, PP, and PETG bottles in a single integrated machine — is a more specialised market served by dedicated ISBM machine manufacturers.

Buyers who need to produce pharmaceutical vials, water bottles, edible oil containers, or cosmetic flacons need an ISBM machine, not a general injection moulding machine. The two categories are not interchangeable.

Largest General Injection Moulding Machine Manufacturers

By revenue and global installed base, the largest injection moulding machine manufacturers serving general plastics production include companies such as Engel (Austria), Arburg (Germany), Husky (Canada — specialising in PET preform injection systems), and several large Chinese manufacturers including Haitian International and Chen Hsong. These companies produce machines for solid part moulding at high volumes.

Husky is specifically significant in the PET packaging chain because it dominates the preform injection moulding segment — machines that produce the preforms later blown into bottles in a two-step process. However, Husky does not manufacture one-step ISBM machines; its machines produce preforms, not finished bottles.

Finished PET and PP bottles produced by one-step ISBM machines — a fundamentally different output from general injection moulding equipment.

Largest One-Step ISBM Machine Manufacturers

The one-step ISBM machine segment is served by a smaller number of specialist manufacturers. The most significant global players include:

• ASB (Nissei ASB, Japan) — one of the oldest and most established one-step ISBM machine manufacturers globally, with machines installed across pharmaceutical, cosmetic, and food packaging applications in over 100 countries.
• Jomar (USA) — specialises in injection blow moulding (IBM) machines for pharmaceutical and personal care containers; a major supplier in North America.
• Ever-Power (China) — a specialist one-step ISBM machine manufacturer with a comprehensive range covering 50–400 kN injection clamping force, supplying markets in Brazil, South Korea, Australia, the Netherlands, the UK, Canada, and Colombia. The EP-HGY and EP-BPET series covers 3-station, 4-station, and 6-station configurations for containers from 30 ml to 10 litres.
• Several Chinese specialist manufacturers — the Chinese ISBM machine segment has grown significantly since 2010, with multiple manufacturers now producing servo-driven one-step machines at competitive price points for export markets.

How to Choose Between ISBM Machine Suppliers

For buyers selecting an ISBM machine supplier, market size is a less useful criterion than application fit, technical capability, and after-sales support. A large general injection moulding machine company is not automatically the best choice for a buyer who needs to produce PET bottles — a specialist ISBM manufacturer with deep process knowledge, matched mould supply, and strong after-sales coverage in your market will outperform a larger but less-specialised supplier on every dimension that matters in production.
