Pet Blowing Machine
Plastic Blowing Machine
DMK-R10 (10 stations, one mould in each station), 15000
Bottles/Hour, 1500 bottles/station/hour.
DMK-R10 is the most stable two-step fully automatic high-speed
rotary PET stretch-blowing machines(reheat). The capacity of the
products is from 0.25L to 2.0L. It can blow pet bottles for
different use: carbonated, mineral water, milk, beer, oil, hot
filling tea, and other drink packing containers, which is made of
plastic of crystalline type, such as PET, PP etc.
DMK-R series has adopted original heating and blowing technics, by
which the automatic blowing machine series have achieved in
powerful productivity but very reasonable price.
B.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 for switching to
different perform sizes.
B.2. Linear Oven
A mandrel capable of turning 180 degrees guarantees uniform neck
section during the heating. A unique oven ventilation system
enables the DMK-R series blower to handle various difficult
1.Power saving: heater is fixed with link ofshort section(43.8mm), which assures to heat more performs with the same heating
length. In this way, it saves electricity of 25%.
2.Water cooling plate: cooling bottle neck avoid neck deformation
3.Infrared heat lamps:
a. Each lamp is individually adjustable;
b. Lamp gripper is adjustable as angle changes;
c. Lamp rod is adjustable in length, which is good for bottom
B.3. Preform and bottle transfer wheel
The new DMK-R series utilizes a classic double cam telescopic
gripper system, this guarantees reliable movement, and easy
B.4. Molds and Mold Carriers
The mold carrier utilizes a shell blow mold design; this reduces
the changeover time for different blow molds. The Mold carriers
accommodate all shell type molds from conventional blow molding
machines, this saves time and expense for bottle producer.
Moreover, the reliable quick locking system maximizes the
performance of the mold carriers.
B.5. Blowing Station
A changeable cam for the stretching curve guider guarantees the
form quality for different size bottles. Monobloc blowing valves
achieve the fastest and most consistent blowing process possible.
Bottle necks are protected during the blowing stage by a specially
designed sealing unit.
C.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. This automatic adjustment avoids the influence of a
temperature difference between day time and night; also the system
can use an additional lamp alarm, this alarm will sound when it
detects any broken or aging lamps.
C.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. In order to lower these production
costs for the bottler producer, Demark Machinery has introduced its
patented Air recovery system. This system recovers up to 30% of the
final high pressure blowing air and ultimately lowers the cost to
C.3. Air cooling system (Option)
Thanks to the design contributions of our engineer, 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. After this air cooling
process, now PET bottles can stand hot filling without deformation.
D.Advantages of Rotary Automatic Stretch-Blow Molding Machines
D.1. High productivity: 1700pcs/cavity/hour
