The core advantage of the semi-automatic 4-chamber bottle blowing machine lies in the precise balance between efficiency and flexibility. It not only achieves capacity improvement through 4-chamber design, but also retains the low-cost and easy to operate characteristics of semi-automatic equipment, perfectly adapting to the production needs of small and medium-sized and multi category production. The specific details are as follows:

Capacity efficiency: Balancing scale and flexibility

Significant increase in production capacity

Compared to 1-chamber and 2-chamber models, the 4-chamber synchronous operation design has significantly increased production. Taking 500ml PET bottles as an example, the hourly production capacity can reach 1200-2000 bottles, which can meet the bulk supply needs of small and medium-sized enterprises while avoiding the problem of overcapacity in fully automated equipment.

Controllable production pace

Although it is designed with 4 chambers, it still retains semi-automatic processes such as manual embryo loading. The production speed can be flexibly adjusted according to actual conditions such as order volume and raw material supply, adapting to flexible production scenarios of multiple batches and small batches, and reducing inventory backlog.

High equipment utilization

With a compact structural design and a footprint smaller than the fully automatic 4-chamber model, capacity upgrades can be achieved within limited factory space; At the same time, single shift and double shift flexible scheduling are available, and the equipment is easy to start and stop without the need for long warm-up periods, improving usage efficiency.

Cost control: low investment, high return

Initial investment economy: The equipment structure is simpler than that of fully automatic models (eliminating complex systems such as automatic embryo loading and testing), and the purchase cost is only 50% -70% of that of fully automatic equipment with the same number of chambers, greatly reducing the initial financial pressure on small and medium-sized businesses and shortening the investment return cycle.

Low labor and operation costs: only 1-2 operators are needed to complete auxiliary tasks such as embryo loading and bottle retrieval, without the need for a professional technical team; The equipment has few components and a mature structure. Daily maintenance only requires basic cleaning and replacement of vulnerable parts, and the operation and maintenance cost is much lower than that of fully automatic equipment.

Energy consumption and raw material optimization: Adopting a partitioned temperature control heating system, combined with precise blowing parameter control, to reduce energy waste; At the same time, 4-chamber synchronous molding ensures uniform wall thickness of the bottle body, and the scrap rate can be controlled within 0.5%, reducing PET raw material loss.

Operation and adaptation: flexible and easy to learn

Low operational threshold: equipped with PLC control system and touch screen human-machine interface, parameter settings (such as temperature, pressure, time) are intuitive and simple, and operators can be on duty after short-term training without the need for highly skilled personnel, solving the problem of employment.

Multi specification quick switching: supports the production of multiple capacity bottle types ranging from 0.2L to 5L, simplifies the mold replacement process (some models have a mold replacement time of ≤ 40 minutes), and can quickly switch bottle types of different categories such as mineral water, juice, sauce, etc., adapting to the needs of brand multi category layout.

Compatible with multiple bottle preforms: It can adapt to PET bottle preforms with mainstream diameters such as 28mm and 38mm, and has a high tolerance for dimensional tolerances of bottle preforms. There is no need for customized bottle preforms, reducing the difficulty and cost of raw material procurement.

Quality and Safety: Stable and Reliable

Stable molding quality: 4-chamber independent temperature control and pressure regulation ensure that the preform in each mold cavity is heated evenly and the blowing pressure is consistent. The weight, wall thickness, and dimensional accuracy of the finished bottles are uniform, improving the attractiveness and performance of the product shelf.

Durable equipment structure: Key components such as the locking mechanism and heating lamp tube are made of highly wear-resistant materials, and the 4-chamber synchronous locking force is balanced, ensuring stable operation, low failure rate, and long average time between failures, reducing the impact of downtime maintenance on production.

Safety protection in place: equipped with infrared safety grating, emergency stop button and other devices. When the operator's hand approaches dangerous areas such as the mold cavity, the equipment automatically stops, and the whole machine meets electrical safety standards, ensuring the safety of personnel during the production process.
