DMK-R12 is the most stable two-step fully automatic high-speed rotary PET stretch-blowing machine(reheat). The capacity of the blow moulding machines 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 techniques, by which the automatic blowing machine series have achieved in powerful productivity but very reasonable price. The construction of the equipment is well-designed. We have perform feeding and loading unit for the blow moulding machines, so the recycling unit prevents the performs 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.

This DMK-R blow moulding machines series utilizes a classic double cam telescopic gripper system, and this guarantees reliable movement and easy maintenance. The mould from conventional equipments can help you save time and expense for bottle producer. Moreover, the reliable quick locking system maximizes the performance of the mould carries. As for the blowing station, there is a changeable camera for the stretching curve guider guarantees the form quality for different sizes of the bottle. Monobloc blowing valves achieve the fastest and most consistent blowing process possible. The bottle necks of the blow moulding machines will be protected during the blowing stage by a specially designed sealing unit.  Demark is composed of a powerful team in research and development including more than seventy intermediate and senior technologists.  In order to meet different clients’ demand, our technologists successfully design and manufacture a series of DMK-R rotary plastic equipment, model number from 4 to 16.

Except for the units, we also have the linear oven, which is a mandrel capable of turning 180 degrees uniform neck section during the heating. A unique oven ventilation system enables this DMK-R10 blow moulding machines handle various difficult applications easily. The power saving heater is fixed with link of short section (43.8mm), which assures to heat more performs with the same heating length, which provides 25% of electricity saving. Besides, we have infrared heat lamps in the blow moulding machines, and each lamp is individually adjustable, so as the lamp gripper for different angles and the rod for different length. Don’t worry about the over-heated problem, because we have cooling bottle neck to avoid neck deformation during heating.


If you are interested in our blow moulding machines, please do not hesitate and make your inquiry any time. We provide not only quality equipment but also after sale service. With good brand reputation and attitude of customer-centric, we invite special technologists responsible for after sales. We provide 24-hour on call service to solve your problems, and we also have fast response for both domestic call and international call. For domestic call, we will provide our services within 12 hours and international call will be handled within 24 hours.

  • High productivity: 1700pcs/cavity/hour
  • High eligible rate: above 99.6%
  • Adopting SIMENS electric controlling system; with high precision and fast speed
  • Stable function:  i). blowing system adopts Germany valve and cylinder, which has stable and accurate stretching speed and good product consistency     ii). heating system adopts PHILIPS original infrared lamps, which is good in thermal properties and high in durability.   iii). Germany SEW main electric motor assures stable rotating speed and stable operation.
  • D.4.Mold fixing structure assures fast mold fixing speed and fast mold changing speed
  • D.5.Automatic plastic loader and automatic recovery device.
  • 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.
  • 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 produce bottles.
  • 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.
  • Advanced Processing Equipment:
Machine center, digital lathe, EDM, such as many imported American and Japanese machine tools assure processing precision and good interchangeable function.
  • CE
  • TUV,ISO9001
