Dongguan Hejin Plastic Machinery Co., Ltd. products

The high efficiency dehumidifying drying system from Hejin is crucial for enhancing the drying efficiency of recycled PET materials. Suitable for a wide range of plastic materials including PET, TPU, PMMA, PLA, SGP, PS, and ABS, this advanced drying system is essential for the early-stage production of plastic products. The system offers a significant reduction in drying time, achieving dehumidification and drying within one hour compared to the traditional five, while also consuming 60% less energy. It employs a two-stage dehumidification process using refrigerated compressed air and a cellular silica gel wheel. The dynamic drying process uses a unique vortex air inlet design to facilitate uniform heat distribution and prevent issues such as caking and yellowing, enhancing the overall drying quality. This equipment optimizes the drying process for industrial applications such as injection molding, extrusion, and other plastic processing methods.

This energy-saving PET crystallizer is a specialized piece of auxiliary equipment designed for efficiently processing and recycling amorphous phase PET materials. Engineered to mix crystallized materials with new PET, it allows simultaneous dehumidification and drying, thus greatly reducing production costs. It is frequently used in PET sheet production operations. The crystallizer prevents bonding through constant speed stirring and supports efficient completion within 30 minutes. Its construction includes a high-grade stainless steel inner wall with mirror surface treatment and a cyclone dust collector to reduce air filter load, enhancing longevity and reducing cleaning frequency. Safety precautions feature a secure circle ladder stand. It also has an 80mm thick insulation layer and aluminum silicate cotton for optimal heat retention.

The Hejin molded desiccant dryer is engineered specifically for plastic molding operations to address the issues caused by mold condensation, a common problem when chilled water is used to expedite the molding process, particularly with PET preforms. By maintaining a low dew point air environment between -8°C and -15°C around the mold, this dryer prevents condensation and reduces the risk of mold corrosion and product defects. It features a cellular rotary design that delivers stable dehumidification, supported by a microprocessor with PID control for precise temperature management. The unit`s drying capabilities range from 1200 to 2400 m3/h and can support one or two injection machines. Its dual-panel construction with thermal insulation provides an efficient, compact design. Hejin, a seasoned player in the plastic industry, offers a range of products and custom solutions to meet specific manufacturing needs, backed by over 25 years of experience.

The HRL series air cooled screw type chiller from Hejin is designed for a wide range of industrial applications, including lithium battery production, solar energy product manufacturing, and plastic molding processes. Offering a refrigeration range of 79,400 kcal/h to 1,720,000 kcal/h and an outlet chilling water temperature range from 5°C to 20°C, the chiller provides a robust cooling solution. The system eliminates the need for auxiliary equipment such as cooling towers and pumps, making it ideal for regions with limited water resources. It is easy to install in spaces like rooftops, conserving building space, and is equipped with intelligent computer controls for seamless remote management. The chiller features protective devices to prevent reverse operation, motor overload, and temperature extremes, ensuring reliable operation. With high-quality components, the unit delivers high refrigerating efficiency.

The gravimetric yield control resin blender is an essential equipment designed for the efficient transportation of various raw materials, including plastic granules, powder, calcium carbonate, talc powder, resin film powder, flour, and starch. Tailored for different material needs, it features two distinct scale bodies: a powder scale for materials with low fluidity and a granular scale to address bridging issues. Key mechanical components such as the screw are engineered for easy disassembly, facilitating hassle-free assembly and cleaning. The blender offers precise feeding performance with both manual and automatic control options. The material collector operates independently with a stable performance and a low failure rate, making it a crucial part of central material conveyance systems. Equipped with a high-performance magnetic sensor and efficient vacuum pump.
