Numerous Chinese producers supply newer types. These incorporate fitted sensors and auto-check tools. As a result, they make the making process even more efficient.
Classification Based on Mold Cavities
Automation plays a significant role. Still, the quantity of mold cavities serves as another important aspect. It connects directly to your making capacity.
Single-Cavity Blow Molding Machines
These devices make one bottle each round. They work best for small-scale or very specific bottle patterns. Their basic structure allows simpler washing and fixing. This advantage helps when facing regular pattern shifts or test productions.
Multi-Cavity Blow Molding Machines
Devices fitted with several cavities—from two to twelve or beyond—deliver strong large-scale making abilities. They call for more detailed cooling arrangements and accurate mold setup. Nevertheless, they achieve much higher work rates. Multi-cavity synchronized operation significantly enhances production efficiency.
Classification Based on Bottle Application
PET bottle uses cover diverse sectors and fill situations. Devices typically group by their backing for hot-fill or cold-fill ways.
Cold-Fill Bottle Blow Molding Machines
Cold-fill devices suit items like spring water and bubbly soft drinks. These fill at room or cooled states. The setups skip heat-durable substances. They commonly aid light bottle structures as well.

This equipment adopts innovative designs such as high-temperature resistant fixtures and an efficient cooling system, which can ensure stable forming parameters after hot filling. The bottle blowing mold is made of high-quality S136 steel and aviation-grade aluminum alloy, featuring outstanding durability and maintaining stable performance even under high-temperature stress.
Classification Based on Blowing Technology
The approach for using air force in bottle building further determines the PET blow molding machine type to choose.
High Pressure Blow Molding Machines
These devices function over 30 bar force. They enable shaping intricate bottle forms with sharp features and provide better wall evenness and clearness. Thus, they suit high-end packaging needs. In those, appearance weighs equally with utility.
Low Pressure Blow Molding Machines
Running at reduced forces results in extended round durations. Yet costs for operation remain smaller. These setups fit simpler tasks like non-sparkling water bottles. There, detailed sharpness or robustness lacks importance.
Customization Options in Chinese Blow Molding Machinery
Adaptability matters greatly in the current trade setting. Chinese blow molding devices present wide adjustment traits. They back numerous making requirements.
Adjustable Neck Finish Systems
These setups enable changing between varied neck types without swapping the full mold group. This function helps manage multiple product codes and speeds up the switching between different product series.
Integration With Mold Cooling Systems
The modern cooling channels set within the mold frame can effectively enhance the heat dissipation performance. The honeycomb-shaped cooling channel structure not only optimizes the heat dissipation efficiency but also significantly shortens the bottle body molding cycle, thereby rapidly increasing the molding speed while ensuring the uniformity of the bottle body molding. This design is particularly effective in forming bottles with multi-chamber structures.
Compatibility With International Mold Standards
Plenty of Chinese-produced devices now match worldwide setups like KHS rotary arrangements. As an example, the PET blowing mold for KHS blow molding machine comes planned exactly for rotary blowing gear. It backs sizes from 50ml to 2500ml. High-quality imported aluminium materials are used for forming cavities.
Factors That Influence Machine Selection
Deciding on the correct blow molding device means weighing tech skills against your work aims.
Production Volume Requirements
Settings with large yields gain from total automatic multi-cavity devices. They increase flow to the utmost. Conversely, focused tasks could see semi-automatic versions as more wallet-friendly.
Bottle Design Complexity
When your bottles feature stamped marks or odd shapes, select devices that handle stretch-blow methods. Combine them with precisely set control systems. These assure consistent outcomes.
Material Compatibility
Every PET substance does not react identically to warmth or force. Make certain your picked device upholds particular kinds. Hot-fill needs resistant varieties. Oxygen blocks support extended shelf periods. Choose them if your good calls for those qualities.
Maintenance Considerations Across Machine Types
The powerful protection performance safeguards your expense security and ensures the long-term stable operation of the device.
