1. Brief Introduction
2. Machine Construction
1. Preform feeding and loading unit
The design of the recycling unit prevents the preforms from getting bound up in the unscrambler. The star wheel design of the feeding unit provides the lowest possible changeover times.
2. Linear Oven
A mandrel capable of turning 180 degrees. A unique oven ventilation system enables the DMK-R series blower to handle various difficult applications easily.
1. Power saving: Heater is fixed with link of short section(43.8mm), it saves electricity of 25%.
3. Water cooling plate: Cooling bottle neck avoid neck deformation during heating.
4. Infrared heat lamps:
A. Each lamp is individually adjustable;
B. Lamp gripper is adjustable as angle changes;
C. Lamp rod is adjustable in length
5. Preform and bottle transfer wheel
The new DMK-R series utilizes a classic double cam telescopic gripper system.
6. Molds and Mold Carriers
The mold carrier utilizes a shell blow mold design; The Mold carriers accommodate all shell type molds from conventional blow molding machines.
7. Blowing Station
A changeable cam for the stretching curve guider guarantees the quality. Monobloc blowing valves achieve the fastest and most consistent blowing process possible.
Options:
1. PID heating zone system (Option)
Within this system, an infrared thermometer automatically detects the temperature of the performs and adjusts the temperature of the oven as needed. The system can use an additional lamp alarm, this alarm will sound when it detects any broken or aging lamps.
2. Patented Air Recovery system (Option)
We know that most of the production costs for blowing bottles are attributed to generating the high pressure compressed air and applying heat to the preforms.
3. Air cooling system (Option)
Demark Machinery has developed a revolutionary air cooling system for hot fill PET bottles. After high pressure blowing, an air cooling stage is introduced to reduce the level of PET residual stress and increase the rate of PET crystallization.
