This guide explains how an IBM machine works, which model fits which bottle, and what to check before you choose a supplier. Use it to compare options and prepare a clear inquiry.
What Is an IBM Machine? (Injection Blow Molding Explained)
An IBM machine is an injection blow molding machine. It makes hollow plastic bottles in one continuous process. The machine injects molten plastic into a preform mold, then blows the preform into the final bottle shape. Buyers also search for it as an injection blow moulding machine, a blow injection molding machine or injection and blow molding equipment. All these terms describe the same technology.IBM suits small and medium bottles. The injection step forms the neck and thread with high accuracy, so caps, droppers and pumps fit well. The finished bottle needs no trimming and has no flash. Main benefits include:
• Accurate neck finish for caps, droppers and pumps
• No flash and no post-trimming step
• Even wall thickness and a clean surface
• Low material waste
• Good repeatability for long production runs
Our IBM Machine Range: ZQ40, ZQ60, ZQ80, ZQ110 and ZQ135
The ZQ series is the core of our Injection Blow Molding Machine line. Each model uses a three-station rotary design with PLC touch-screen control. The five models cover bottle sizes from very small to large:• ZQ40: compact model for very small bottles, such as eye drop and sample bottles
• ZQ60: for eye drop, nasal spray, oral liquid and small medical bottles
• ZQ80: for mid-size bottles, such as syrup, vitamin and personal care bottles
• ZQ110: for larger cosmetic, food and liquid medicine bottles
• ZQ135: for large-volume bottles and higher-capacity production
Several models are also available as full electric HE versions. Our team can help you match the model to your bottle size, material and output target.
All-Electric, Servo and Hydraulic Injection Blow Molding Machines
The drive system affects energy cost, precision and maintenance. We supply three options:• Hydraulic: proven design with a lower purchase price. A good fit when budget is the main concern.
• Servo: servo motors drive the hydraulic system. Energy use is lower than a standard hydraulic machine, and control is more precise.
• All-electric: servo motors drive the movements directly. The machine runs oil-free and offers the highest repeatability.
A full electric injection blow molding machine suits pharmaceutical and cosmetic buyers who need clean production. In our own comparison, a full electric IBM machine can cut power use by 30–60% against hydraulic models. Actual savings depend on the mold, material and cycle time.
How to choose a drive system
Choose hydraulic for the lowest upfront cost. Choose servo for a balance of cost and efficiency. Choose a full electric blowing machine if you run clean-room production, multiple shifts or high electricity prices.IBM Machine for Pharmaceutical and Eye Drop Bottles
Pharmaceutical bottles need tight neck tolerances, clean production and stable quality. An IBM machine meets these needs better than most other bottle-making methods, especially for small sizes. Typical products include:•Eye drop bottles with dropper-ready necks
•Nasal spray and oral liquid bottles
•Syrup and medicine bottles
•Tablet and capsule containers
What pharmaceutical buyers should check
Ask for oil-free drive options, material compatibility and neck finish accuracy. Request the compliance documents your market requires, and confirm them before you order. Our team can discuss your bottle drawing and regulatory needs.IBM Machine for Cosmetic and Personal Care Bottles
Cosmetic brands care about bottle appearance as much as function. Injection blow molding gives smooth surfaces and consistent wall thickness. It works well for:•Lotion, serum and toner bottles
•Travel-size and sample bottles
•Small personal care bottles with pumps or droppers
A custom mold lets you control the bottle shape, neck style and cavity count. This helps brand owners launch a distinct package without changing the machine.
IBM Machine for Food and Household Bottles
Food and household packaging often needs larger volumes and strong, leak-resistant bottles. Our mid-size and large ZQ models produce:•Seasoning and additive bottles
•Household cleaning and care bottles
•Large-volume bottles for daily-use products
For food contact products, confirm that your resin grade meets the rules in your target market.
How Does an IBM Machine Work? The 3-Station Process
The machine moves the core rod through three stations on a rotary table. Each station works at the same time, which raises output per cycle.1. Injection station: molten plastic is injected around the core rod to form the preform, including the neck and thread.
2. Blowing station: the preform moves into the blow mold. Compressed air expands it to the final bottle shape.
3. Ejection station: the finished bottle is released and moves out, often onto a conveyor.
Because the neck is injection molded, the bottle needs no trimming. The process also avoids parting lines on the body.
IBM Machine vs Extrusion Blow Molding Machine: Key Differences
Buyers often compare an IBM machine with an extrusion blow molding machine. The right choice depends on bottle size and design.| Factor | IBM (Injection Blow Molding) | EBM (Extrusion Blow Molding) |
| Typical bottle size | Small to medium (about 1 ml to 500 ml) | Medium to large (500 ml and above) |
| Neck accuracy | Very high, injection molded | Standard, usually needs trimming |
| Flash and trimming | No flash, no trimming | Flash trimming is common |
| Handles and complex shapes | Limited | Well suited |
| Best for | Pharmaceutical, cosmetic and small food bottles | Large containers and household bottles |
Choose IBM for small, precise bottles. Choose extrusion blow molding for large containers or bottles with handles. For clear PET beverage bottles, consider an injection stretch blow moulding machine. We supply these machine types too, so you can compare them with one supplier.

Supplier checklist for international buyers
Before you choose any blow molding machine manufacturer, ask these questions:•Can the supplier share certificates and test records for your market?
•Does the supplier provide written cycle time and output data?
•Which parts and services does the warranty cover?
•Are spare parts and technical support available after delivery?
•Does the mold match the exact machine model?
A reliable blow molding machine supplier answers these clearly and in writing.
Custom Molds and OEM/ODM Service for Injection Blow Molding
The mold shapes your bottle, so it matters as much as the machine. We support OEM/ODM molds for custom bottle designs. Send us a drawing or a sample, and we will review:
•Bottle shape, volume and neck finish
•Number of cavities and expected output
•Mold steel and cooling design
•Compatibility with the machine model
A mold drawing review before production helps you avoid costly changes later.
PET, PP, PE and PETG: Materials Our IBM Machines Can Process
Material choice affects bottle clarity, strength and chemical resistance. Most injection blow molding projects use these resins:•PP: semi-transparent and heat resistant. Common for eye drops, syrups and sprays.
•PE (HDPE and LDPE): chemical resistant and light. HDPE suits tablet bottles, while LDPE suits soft, squeezable bottles.
•PETG: clearer bottles, depending on the machine and mold setup.
•PET: best made on a one-step injection stretch blow molding machine for strong, clear bottles.
Many buyers search for a PE blowing machine or a PE bottle blowing machine for small PE bottles. Our ZQ series fits this need. Tell us your resin grade and bottle design, and we will confirm the right machine and mold setup.
