1. Injection Stretch Blow Molding (ISBM) Machines:
Technology: ISBM machines combine injection molding and stretch blow molding processes. They first inject molten plastic into a preform mold to create a preform, which is then transferred to a blow mold where it is stretched and blown into the final bottle shape.
Capabilities: ISBM machines are suitable for producing bottles with complex shapes and precise dimensions. They are commonly used for manufacturing PET (polyethylene terephthalate) bottles for beverages, personal care products, and household items.
2. Extrusion Blow Molding (EBM) Machines:
Technology: EBM machines utilize the extrusion process to create a parison, a tube-like plastic material. The parison is then placed in a blow mold where it is inflated to form the final bottle shape.
Capabilities: EBM machines are versatile and capable of producing bottles with different sizes and shapes, ranging from small containers to large drums. They are commonly used for manufacturing HDPE (high-density polyethylene) and PP (polypropylene) bottles for various applications, including cosmetics, pharmaceuticals, and industrial products.
3. Injection Blow Molding (IBM) Machines:
Technology: IBM machines combine injection molding and blow molding processes. They first inject molten plastic into a cavity mold to create a preform, which is then transferred to a blow mold where it is inflated and blown into the final bottle shape.
Capabilities: IBM machines are known for their high precision and accuracy in producing bottles with consistent wall thickness and dimensions. They are commonly used for manufacturing bottles for pharmaceuticals, medical devices, and personal care products.
4. Stretch Blow Molding (SBM) Machines:
Technology: SBM machines are designed specifically for PET bottle production. They use a two-step process where a preform is first created through injection molding, and then reheated and stretched in the blow mold to form the final bottle shape.
Capabilities: SBM machines offer high production speed and efficiency, making them suitable for high-volume production of PET bottles for beverages, edible oils, and other liquid products.
5. Rotary Blow Molding Machines:
Technology: Rotary blow molding machines consist of multiple molds mounted on a rotating wheel. This allows for continuous production, as one mold is filled while another is in the blow molding process.

Capabilities: Rotary blow molding machines are ideal for high-speed production and can produce a large number of bottles per hour. They are commonly used for manufacturing bottles for carbonated beverages, water, and other liquids.
6. Accumulation Blow Molding Machines:
Technology: Accumulation blow molding machines utilize an accumulator head to accumulate molten plastic and then extrude it into a parison. The parison is then transferred to a blow mold where it is inflated to create the final bottle shape.
Capabilities: Accumulation blow molding machines are suitable for producing large and heavy-duty bottles, such as automotive fuel tanks, industrial containers, and large water storage tanks.
In summary, the different types of bottle making machines available in the market offer various technologies and capabilities to cater to different production needs. The selection of the appropriate machine depends on factors such as the type of plastic material, bottle design requirements, production volume, and desired output. Understanding the differences in technology and capabilities of these machines is crucial in choosing the right bottle making machine for specific production requirements.
Extrusion blow molding machine and injection blow molding machine are two popular manufacturing processes used in the production of plastic bottles and containers Both techniques have their own advantages and disadvantages, and it is important to understand the differences between the two to make an informed decision when choosing the right manufacturing process for your product.
Extrusion blow molding (EBM) is a one-step process where the melted plastic will be extruded into a hollow tube,which we known as a parison,then inflated to form the desired shape. The parison is clamped between two halves of a mold and then air is blown into it to form the shape as final product. EBM is commonly used for larger containers and bottles, such as #jerry cans and drums.But it could also use for diary products like #milk #bottle,#yogurtbottle,and many the washing products bottle use extrusion blow molding machine as well.For example:detergent bottle,cleanser essence bottle,shampoo bottle,etc...

Injection blow molding (IBM) is a two-step process where a preform is first molded, then inflated to the desired shape in a blow mold. The preform is made by injecting melted plastic into a mold and then cooled. Then transferred to the blow mold where it is inflated and held against the mold walls to form the desired shape. Some of the customer they produce the preform by themselves and some of the customer will buy the preform. IBM is typically used to produce small containers and bottles with intricate shapes and designs.

One key difference between the two processes is the amount of control over the final product. In extrusion blow molding machine(EBM), the final product is formed in one step, so there is less control over the final shape and design.In injection blow molding machine(IBM), the preform mold is where the majority of the design is determined and the blow mold is used to finalize the shape.
Another difference is the cost of the equipment. Injection blow molding(IBM) machines are typically more expensive than extrusion blow molding(EBM) machines due to their complexity and the need for two molds. Extrusion blow molding(EBM) machines are typically less expensive due to their simplicity and the need for only one mold.
The choice between injection blow molding machine(IBM) and extrusion blow molding machine(EBM) will depend on a variety of factors, including the size and shape of the desired product, the budget for equipment, and the desired level of control over the final product. Understanding the differences between the two processes will help you make an informed decision when choosing the right manufacturing process for your product.
