Our 15L semi automatic bottle blowing machine is a professional blow molding equipment specially designed for 15L PET plastic bottle production in chemical, edible oil and daily chemical industries. This model is tailored for small and medium-sized enterprises, featuring simple operation, low investment cost, and stable forming quality, which is the ideal choice for 15L bottle production with small to medium batch sizes.Our 15L semi automatic bottle blowing machine has been upgraded in 2026, with an optimized heating system that shortens the preheating time of 15L bottle blanks by 10%, further improving production efficiency.

Core Features

As a high-compatibility semi-automatic blow molding machine for 15L bottles, the HQ-15L stands out with practical technical advantages. Its core design integrates high-pressure pneumatic forming and internal heating technology, directly addressing the pain points of small-scale manufacturers: unstable forming, high energy consumption and complex operation.The 15L semi automatic bottle blowing machine supports mold customization for different neck sizes of 15L PET bottles, meeting the diversified packaging needs of chemical and food industries.

15L Ultra-High Compatibility for Multi-Type Containers

The HQ-100 features ultra-high compatibility, capable of producing all types of plastic bottles and special irregular containers within 15L, including oil bottles, soda bottles, mineral water bottles, liquor bottles, medicine bottles, chemical bottles and tennis ball cans. The adjustable mold clamping system and stretch stroke adapt to different bottle shapes and capacities, realizing “one machine for multiple purposes” and effectively reducing equipment investment costs for enterprises.

High-Pressure Pneumatic Blowing & Internal Gas Storage

Adopting high-pressure pneumatic blowing technology (blowing pressure 2.5-4.0MPa) and internal gas storage system, the HQ-15L ensures stable and continuous air supply during the forming process. This design solves the problem of uneven bottle wall thickness caused by unstable air pressure, improving the forming qualification rate to over 99%. The internal gas storage function also reduces energy consumption by recycling residual high-pressure gas, conforming to energy-saving production trends.

PLC Intelligent Control System for Simple Operation

Equipped with an advanced PLC computer control system (adopting international brand core components such as Omron CP1H series), the HQ-15L realizes intelligent operation of the whole production process. The humanized operation interface allows operators to easily set and adjust process parameters such as temperature, blowing pressure and time. It also supports real-time monitoring of equipment operation status and fault alarm, enabling ordinary workers to master the operation skills after simple training—no professional technical background required, greatly reducing training costs and operation difficulty.

Internal Heating for Heavy-Weight Preforms Forming

The HQ-15L is specially equipped with an efficient internal heating system, which provides uniform and sufficient heating for heavy-weight preforms (thickness ≥5mm). The multi-zone independent temperature control (temperature range 90-135℃) ensures consistent heating of preforms, avoiding forming defects such as crystallization and cracking. This design expands the machine’s application range, making it suitable for producing thick-walled bottles and special containers that require high structural strength.

Low Energy Consumption & Compact Small Footprint

Adopting an optimized energy-saving structural design and efficient heating system, the HQ-15L achieves low energy consumption while ensuring high output. Compared with similar products in the market, its energy consumption is reduced by 15%-20%, effectively saving long-term operation costs for enterprises. At the same time, the machine has a compact structure with a small footprint (3200×800×2200 mm approx.), which is suitable for small and medium-sized factories with limited workshop space.
