PET preform system solution

In the PET preform system process, drying becomes a particularly critical stage. It must be ensured that the moisture in the raw materials is removed and the drying temperature is reasonable. Hengyin's dehumidifying dryer can provide low dew point below -40°C, and dry air ensures the material is fully dried.
Hengyi is relying on its technical strength in the field of plastic auxiliary machinery to meet all requirements from plastics conveying, dehumidifying and drying, mold temperature and cooling, recycling materials utilization and color management. Its energy-saving environmental protection control technology, energy-saving three-in-one dehumidification dryer, advanced technology, superior performance, and very time-saving, we can achieve customized tailor-made different system solutions.

Drying system
In the PET preform system process, drying becomes a particularly critical stage. It must be ensured that the moisture in the raw materials is removed and the drying temperature is reasonable. Hengyin's dehumidifying dryer can provide low dew point below -40°C, and dry air ensures the material is fully dried.
Dew point setting and intelligent regeneration function, the dew point temperature of the traditional dehumidifier can not be set, the dehumidifier is working in the maximum load state. However, the dew point must be set and controlled when the processing of PET raw materials requires high humidity. The dew point temperature can be set to be linked to the control of the regenerative energy. The main components of the constant dehumidification honeycomb dehumidifier are imported components, which are elaborate and colorful, and the high-efficiency drying operation is performed for the assembly of the good workers (for PA, PC, PBT, PET, etc.). .

Mold dehumidification system
Condensation is like when the mold surface temperature is lower than the dew point temperature of the ambient air, it will produce water vapor, which will affect the product quality and production efficiency. At the same time, it will corrode the mold surface and cause environmental pollution. Hengyin mold dehumidifier does not allow the mold to have dew condensation and is not affected by seasonal changes. It significantly reduces the defective rate. The outlet pretends to be a cooler, ensures a low dry air temperature, enhances the dewing effect, and ensures stable molding conditions. The maximum production capacity of the PET system.

PET crystallization machine
Hengyin PET crystallizer is specially designed to overcome the glass transition temperature of raw materials and ensure the homogenous crystallization, avoiding the occurrence of bonding or bridging of raw materials. The crystallization tank capacity ranges from 25KG to 5000KG.
The material level detection system can adjust the operation mode of the crystallization machine and the feeding device according to the actual amount of raw materials detected by the material level meter. An accurate temperature-sensing control system is adopted, and the discharge port is equipped with a rotary cutting valve to achieve continuous crystallization and prevent degradation.
Satisfy the needs of different raw materials, design safety, easy to clean.
Color matching system
Constant volumetric masterbatch can be used for crystallization and non-crystalline grain color masterbatch raw materials, the production range of 0.2 ~ 32kg/hr. If the customer has higher requirements on the proportion and accuracy of masterbatch addition, we recommend the use of weightless masterbatch, which uses a weightless metering method with a production range of 0.04~32kg/hr.
The internal cooling water circulation cooling function prevents the possible transfer of the masterbatch pellets into the possible melting of the PET main stream, thus ensuring accurate metering. A masterbatch can be set up for a few die cycles to meet the micro metering requirements.
Weighing Mixer
Special high-temperature weigher mixer design, including load cell and material level detector, can handle PET crystallization high temperature raw material processing.
The controller is equipped with an Ethernet interface, and the corresponding software can read raw material ratio data (such as maximum output, actual output, and ratio accuracy) through this communication interface to facilitate product quality control.
Color graphics display, touch screen operation, formula storage function, can store up to 100 or more recipes, use advanced control algorithms, independent optimization, PLC controller, reliable performance, easy maintenance.
Automatic conveyor system
The parts in contact with the raw materials are made of stainless steel and the filtration system of the delivery system, which effectively ensures that PET raw materials are not contaminated during the transportation process. The flexible conveying air adjustment system can effectively prevent the PET raw material from drawing or dust due to different conveying conditions by adjusting the conveying speed.
With the PET high-temperature raw material delivery system, Henghan has specially designed a solution with water cooling function, which reduces the risk of the suction machine for high-temperature raw materials.
In the closed-cycle secondary transport system, Henghan can greatly reduce the risk of heat loss during transportation and the risk of reabsorption of moisture after drying for the hot material and the heat transfer hopper that needs to be sent to the molding machine after drying.
cooling system
Hengyin's chiller cooling system can accurately control the temperature, flow and pressure to maximize the cooling effect. Its products include air-cooled and water-cooled chillers, cooling towers, pumps, and water tanks. Based on the standard equipment technology, Hengyi can provide customers with personalized solutions that meet different needs.
Water/air-cooled ice water machine, open chiller, new famous brand compressor and evaporator combination, super cooling, quiet power saving. There are single, dual, and four-machine combinations that have high energy efficiency.
