DR-2500 High Temperature Resistant Automatic Blow Molding Machine

The DR-2500 series blow molding machine is our company's latest two-step manual preform insertion automatic blow molding equipment, capable of producing bottles of 0.6L, 2.0L, and 5L sizes. It is suitable for blowing any shape of carbonated beverage bottles, mineral water bottles, pesticide bottles, cosmetic bottles, high-temperature resistant bottles, and other packaging containers made from crystalline plastics such as PET and PP.

The biggest difference between the DR-2500 manual preform insertion series and other fully automatic preform feeding series is that the DR-2500 series machines do not have an automatic conveyor for feeding preforms (tube preforms); preforms must be inserted manually. The biggest advantages of the manual insertion design are: significantly reduced production costs; lower scrap rate compared to semi-automatic blow molding machines; faster production speed; stable performance; and extremely simple operation. It will replace semi-automatic blow molding machines.

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-2500 operates using a two-stage stretch blow molding process optimized for high-temperature PET preforms.

Production Workflow

1. Preform Feeding
   Preforms are automatically loaded and positioned.

2. Infrared Heating
   Preforms are heated evenly to the target temperature for optimal stretchability.

3. Stretching Stage
   Stretch rods elongate the preform to improve molecular orientation.

4. High-Pressure Blowing
   Compressed air expands the preform into the mold cavity, forming the bottle shape.

5. Cooling Stage
   The mold cools the bottle to stabilize its dimensions.

6. Automatic Ejection
   Finished bottles are discharged for collection or further processing.
