DR-A Hand-operated Fully Automatic Blow Molding Machine

The DR-A series blow molding machine is our company's latest two-step manual preform insertion automatic blow molding equipment, ranging from one-outlet to one-outlet-six-outlet, with a maximum blowing capacity of 0.6 liters and 2.5 liters. It is suitable for blowing any shape of carbonated beverage bottles, mineral water bottles, large-diameter bottles, cosmetic bottles, high-temperature resistant bottles, and other packaging containers made from crystalline plastics such as PET and PP.

Features

Employing an advanced microcomputer control system, ensuring stable performance;

Automatic preform feeding via conveyor;

Using infrared lamps for heating, providing strong penetration, preforms rotate and are heated simultaneously via track revolution, resulting in uniform, rapid, and reliable heating;

The width and height of the lamps and reflectors within the heating zone are adjustable to suit preforms of different structures, and an automatic temperature control device ensures constant temperature in the drying tunnel;

Each mechanical action has a safety self-locking device; if a process malfunctions, the program automatically switches to a safe state;

Each action is driven by an oil pump, offering advantages such as zero pollution and low noise;

The air circuit design divides the actions and blowing into three parts to meet the needs of bottle blowing and actions. Different gas pressure requirements;

High-pressure and double-arc arm connecting rod clamping provides strong clamping force;

Manual and fully automatic operation modes are available;

Safe and reliable, the unique valve position design makes the gas path clearly visible;

Bottles are protected from contamination, the cooling system achieves ideal cooling effect, installation and start-up are simple, and the bottle scrap rate is less than 0.2%;

The entire production process is automated, offering advantages such as low investment, high efficiency, convenient operation, simple maintenance, and safety.

Key Definitions

3. Working Principle

The DR-A machine operates on a two-step stretch blow molding process, enhanced by flexible operation controls.

Step-by-Step Production Workflow

1. Preform Loading
   Preforms are manually or automatically loaded into the feeding system.

2. Heating Stage
   Preforms are heated in an infrared oven to optimal forming temperature.

3. Stretching Stage
   Stretch rods elongate the preforms to improve molecular orientation and bottle strength.

4. High-Pressure Blowing
   Compressed air expands the preforms into molds.

5. Cooling Phase
   Mold cooling ensures dimensional stability and prevents deformation.

6. Manual or Automated Ejection
   Finished bottles are removed from molds, either via automated or manually-assisted discharge.

4. Flexible Operation Control

The DR-A machine stands out due to its hand-operated control interface, offering precise adjustment during production.
