Professional and efficient auxiliary machinery
PET bottle preform molding dedicated dryer, loader and chiller.
Save Time and Manpower As the hopper body and bottom are designed separately, therefore it is convenient to clean materials and quite simple and quick to renew materials as well. A,L feet frames, reciever of hot air, the filter of inlet of fan, the filter of air exhauster, magnetic base, magnetic iron of bunker are available for selection.
XD dehumidifying,drying and feeding unit equipped honeycomb dehumidifier. The moistureproof drying material tube adopt bottom blowing design with circling air exhausting device,prevent heat energy emitting keep temperature, improve drying effiency.The dew-point monitor indicator for customer selection, which can monitor the dew-point.
Mircocomputer control system, control machine running automatically(with timing switch and full-functional alarming system)
The main engine and the material hopper are designed separately, and thus it is safe, easy and convenient to be operated .The whole operation is controlled by MicroTrip computer.Equipped with an independent filter, which is very convenient to clean up dust.
XMD mold dehumidifier is mainly used in the plastic and rubber molding. As the mold use the cooling water to reduce the moulding cycle, which result in the problem of water condensation, it is the most applicable for PET and XMD bottle shooting out particularly.
The conveyor belt ensures fast, stable and efficient transfer of preforms on the production line, reducing manual handling and waiting time and making it more intelligent and automated.
• Complete model spectrum: from 2-cavity to 6-cavity, 0.1 L–20 L, 1,000–4,500 bph.
• Servo + IR precision heating: 32-bit embedded processor with phase-triggered power control; lamp power is linearly adjustable; preforms rotate and revolve for even heating and high clarity.
• Energy-saving design: compact oven with continuous rotary heating saves 20–30 % power versus traditional models; three-stage air circuit (low-pressure motion/pre-blow, high-pressure blow) minimizes air consumption.
• High stability: double-crank toggle clamping, rigid linear guides, Delta control system; automatic fault alarm; mold change in 30 min.
• Two layouts: in-line or stand-alone, seamlessly connecting to the blow-molder discharge conveyor.
• Servo positioning + robot gripper, one-shot snap-in, yield ≥ 99.5 %.
• Handles fit bottle necks 30–120 mm; jig change in 10 min; single- or dual-head models 1,200–2,400 bph.
