DR-B2000-2 Semi-Automatic Blow Molding Machine

This infrared multi-functional plastic preform heater is powered by a three-phase four-wire 380V power supply (220V power can also be used). The machine consists of seven layers of heating lamps, divided into four heating zones. The electrical box contains heating control elements. Preheating time is generally 5-8 minutes. Temperature is automatically controlled by a temperature controller via thermocouples, ensuring stable temperature control within the heating chamber. The strong infrared penetration provides uniform, rapid, and reliable heating, guaranteeing ideal heating results for the preforms. Production begins after the preforms have completed one cycle of heating. The specific temperature is adjusted according to the bottle forming requirements.

This unit is well-equipped, produces stable product quality, and has a wide range of applications. It boasts advantages such as low investment, low cost, low power consumption, quick return on investment, and easy operation. It is an ideal packaging machinery widely used by manufacturers of mineral water, beverages, pesticides, chemical reagents, pharmaceuticals, and oils.

Key Characteristics

3. Working Principle of DR-B2000-2

The DR-B2000-2 operates using a two-step stretch blow molding process, which ensures high-quality bottle production.

Step-by-Step Process

1. Preform Production
   PET preforms are produced using injection molding machines.

2. Infrared Heating
   Preforms are heated uniformly using infrared heating lamps.

3. Manual Loading
