Zhangjiagang Ziqiang Machinery Co., Ltd. is an injection blow molding machine (IBM) factory in Jiangsu, China. We build one-step IBM machines for small plastic bottles used in pharmaceutical, cosmetic, food and household packaging. This guide explains our machine range, typical applications and the checks that help you compare suppliers before you send an inquiry.
All-Electric, Servo & Hydraulic Injection Blow Molding Machines
We offer three drive options, so you can match the injection blow molding machine to your budget, energy cost and bottle type.• All-electric: Electric motors drive the main movements instead of hydraulic oil. This suits clean packaging such as pharmaceutical and eye drop bottles, and it usually lowers energy use.
• Servo: A servo motor controls the hydraulic system. It saves energy compared with a standard hydraulic setup and keeps movement stable.
• Hydraulic: A proven design with simple maintenance. It is a practical choice when purchase price matters most.
Our IBM machines use a one-step process and PLC control. Tell us your bottle, output target and local power supply, and we will suggest the right drive option.
ZQ40 to ZQ135 IBM Machine Series for Small Plastic Bottles
Our Injection Blow Molding Machine range includes five models: ZQ40, ZQ60, ZQ80, ZQ110 and ZQ135. Several models let you choose a size that fits your bottle volume, cavity number and production plan, so you do not pay for capacity you do not need.Exact specifications depend on the model and the mold. These include clamping force, injection volume, cavity number and bottle size range. The right choice depends on your bottle, so send us a sample or drawing. Our team will recommend a model and confirm the specifications in writing.
Injection Blow Molding Machine for Pharmaceutical Bottles
Pharmaceutical packaging puts quality first. Tablet, capsule, syrup and ointment bottles need accurate neck threads, smooth inner surfaces and consistent weight. An injection blow molding machine suits this work because the injection mold forms the neck, and the finished bottle has no weld seam and no flash to trim.Material and cleanliness matter as much as the machine. Check that your resin, production environment and bottle design meet the rules in your target market. We can discuss machine configuration and mold design with your quality team.
Injection Blow Molding Machine for Cosmetic and Eye Drop Bottles
Cosmetic and eye drop bottles are small, and every detail shows. Buyers usually need tight neck dimensions for droppers and pumps, clear or evenly colored walls, and a clean base. An IBM machine forms these features in one cycle, so the bottles come out finished. Typical products include:• Eye drop and dropper bottles
• Lotion, skin care and personal care bottles
• Sample and travel-size bottles
Multi-cavity molds can raise output for small bottle sizes. Ask us which cavity layout fits your machine model and bottle size.
Blow Molding Machine for Food and Household Bottles
Small bottles for food and daily use are a steady market. Examples include seasoning bottles, supplement bottles and household product bottles. Our applications also cover larger-volume bottles, so you can discuss several bottle types with one supplier.For food contact, choose a food-grade resin and confirm the rules in your import market. We can help you plan the mold and the blow molding machine around the resin you select.

What Is an Injection Blow Molding Machine?
An injection blow molding machine makes hollow plastic bottles in one continuous process. It injects molten plastic into a mold to form a preform with the finished neck, then blows the preform into the final bottle shape. It is mainly used for small, precise bottles.Unlike extrusion blowing, IBM forms the neck by injection. The thread is accurate, and the bottle needs no neck trimming. Most IBM machines are built for small and medium bottle sizes.
How Does an IBM Machine Make Small Plastic Bottles?
The process has four steps:
1. Injection: The machine melts plastic and injects it around a core rod to form a preform.
2. Transfer: The core rod moves the preform to the blowing station.
3. Blowing: Compressed air inflates the preform against the bottle mold.
4. Ejection: The machine releases the finished bottle, and the cycle repeats.
These steps run at the same time on different stations. This keeps cycle times short and results repeatable.
Injection Blow Molding vs Extrusion Blow Molding: Which Is Better for Small Bottles?
Both methods make hollow bottles, but they suit different jobs. Our guide, Types of Blow Molding Machine: 3 Main Types Explained, covers EBM, IBM and ISBM in more detail. This table gives a general comparison:| Feature | Injection Blow Molding (IBM) | Extrusion Blow Molding (EBM) |
| Neck accuracy | High. The neck is injection molded. | Lower. The neck usually needs trimming. |
| Material waste | Very little. No flash. | Flash is trimmed and usually reground. |
| Typical bottle size | Small to medium | Small to very large |
| Handles and complex shapes | Limited | Possible |
| Wall thickness | Consistent and easy to control | Depends on parison control |
| Best for | Pharmaceutical, cosmetic and eye drop bottles | Jerry cans, drums and large bottles |
For small bottles with precise necks, IBM is usually the better fit. For larger bottles, handles or irregular shapes, EBM is often more practical. For PET bottles that need high clarity and strength, ISBM is the usual route. We supply all three machine types.
How to Choose the Right Blow Molding Machine for Your Bottle Size and Output
Bottle size, shape and neck
List the bottle volume, neck finish and wall thickness first. IBM works best for small bottles with precise necks. If your design has a handle, consider EBM instead.Material
State your resin early. Common choices include PE, PP, PS and PET-based materials. The material affects mold design, temperature settings and the machine you need.Output and cavities
Set a realistic hourly target. More cavities raise output, but they also need a larger machine and a more precise mold.Supplier support
Ask every supplier for a written specification, sample bottles or test videos, spare parts support and clear warranty terms. A supplier who asks detailed questions about your bottle is usually a better partner than one who quotes a price straight away.What Affects the Price of an Injection Blow Molding Machine?
The price of an injection blow molding machine is not a single number. These factors move it up or down:• Model size, from ZQ40 to ZQ135
• Drive type: all-electric, servo or hydraulic
• Number of cavities and mold design
• Control system and automation options
• Auxiliary equipment
• Shipping, installation and training
Compare quotations line by line. A low price may leave out molds, spare parts or training. Ask what is included before you decide.
