Advantages of Semi Auto Blow Moulding Machine
- High space utilization: The equipment adopts a compact design, with dimensions of only 2.17×0.78×1.94m or 2.48×0.7×1.57m. It occupies little space while maintaining a stable structure, ensuring smooth operation even in limited factory areas and greatly saving production space resources.
Low operation threshold: No complex technical training is required — one worker can complete the entire operation process from placing the preform to taking out the finished bottle. The steps are simple and easy to learn, effectively reducing labor costs and management difficulty, especially suitable for small-scale production enterprises.
Outstanding economic efficiency: As an energy-saving and technically optimized model, the semi automatic blow molding machine features comprehensive functions and low energy consumption, with a rated heating power of only 21kw. It reduces energy expenses in long-term operation, while its reasonable purchase cost makes it an economical investment that helps enterprises achieve stable production with low input.


Key Structural Designs of Semi Auto Blow Moulding Machine
- Accurate and stable clamping system: It adopts a new double-curved arm clamping structure combined with a cross-balanced fixed sliding design. This ensures precise mold positioning during clamping, minimizing deviation and ensuring consistent bottle forming quality, thereby improving the qualified rate of finished bottles.
Clear and reliable air circuit design: The machine features a dependable valve layout with clear air distribution. Operators can quickly locate air circuit issues, making daily maintenance easier and reducing downtime, thus ensuring continuous production and avoiding capacity loss caused by machine stoppage.

Supporting Features of Semi Auto Blow Moulding Machine
- Customized mold compatibility: The machine supports customized bottle molds based on production requirements. Whether for plastic bottles of different capacities or uniquely shaped packaging bottles, it ensures precise compatibility. The molds are made from high-strength materials with excellent wear and heat resistance, effectively extending service life and reducing mold replacement costs.
User-friendly control panel: Equipped with a push-button control panel, the interface is simple and intuitive. Machine status and parameter settings are clearly displayed, allowing operators to quickly adjust production parameters—such as heating temperature based on preform material—to ensure consistent product quality. Meanwhile, the cost-effective panel design reduces overall equipment cost.
Heating System Features of Semi Auto Blow Moulding Machine
The equipment adopts lamp tube heating technology, providing strong uniformity and fast, even heating of preforms. This prevents deformation and uneven wall thickness caused by overheating or insufficient heating. The efficient and reliable heating system shortens preheating time, and with 19 preform heads, it further enhances production efficiency.

Case Study
The YG semi automatic blow molding machine, with its excellent adaptability, successfully solved the bottle supply problem for a medium-sized beverage producer in Kenya. After introducing the semi automatic pet bottle blowing machine, its compact 2.17×0.78×1.94m size perfectly fit the small factory, and the 100pcs/h capacity fully met daily bottle production needs. One operator, after simple training, could independently handle production, greatly reducing labor costs. In addition, the company customized bottle molds for its juice bottles, and with the lamp tube heating system, the produced PET bottles featured uniform wall thickness and smooth appearance, fully meeting local market standards.
In summary, the semi automatic pet bottle blowing machine, with its small footprint, easy operation, and excellent cost efficiency, provides an ideal solution for small and medium-sized plastic bottle manufacturers. Its well-designed structure and comprehensive supporting systems help enterprises stabilize production, improve quality, and control costs efficiently.
