Deqing Leixin Coating Equipment Co., Ltd., established in 2011, is a professional manufacturer specializing in plastic drying and conveying systems. Our Plastic Product Drying Line for Injection Molding Dehumidification integrates automatic feeding and discharging functions, ensuring a seamless, energy-efficient drying process for hygroscopic materials. With a factory area of 1,000-3,000 sqm, ISO9001 certification, and annual export value of US$1-1.5 million, we deliver reliable, high-performance solutions for global injection molding plants.
This drying line is engineered to remove moisture from plastic pellets before injection molding, preventing defects like splay, bubbles, and weak parts. The system features a dehumidifying hopper dryer, automatic material loader, and a discharging mechanism that works in sync with the molding machine. Its modular design allows easy integration into existing production lines, reducing labor and improving consistency.
Key Features & Technical Specifications
Dehumidification Performance: Uses desiccant or compressed air dehumidification to achieve dew point as low as -40°C, ensuring thorough drying of PA, PET, PC, ABS, etc.
Automatic Feeding: Vacuum loader conveys material from storage to drying hopper without manual intervention; filters prevent dust contamination.
Discharging Mechanism: Controlled discharge valve synchronizes with injection molding machine cycle time, maintaining constant material level in the hopper.
Energy Saving: Insulated hopper and intelligent temperature control reduce heat loss; optional closed-loop regeneration system cuts energy consumption by up to 30%.
User-Friendly Control: PLC with touch screen (optional) allows setting drying temperature, time, and material level parameters; alarms for abnormal conditions.

Frequently Asked Questions
Q1: What materials can this drying line handle?
A: It is suitable for hygroscopic plastics such as PA, PET, PC, ABS, PMMA, PBT, and many others. For non-hygroscopic materials, a standard hot air dryer may suffice, but our dehumidification system can also be used for consistent results.
Q2: How does the automatic feeding and discharging work?
A: The vacuum loader pulls material from a storage container into the drying hopper. A level sensor controls the feeding frequency. When the injection molding machine requires material, the discharge valve opens automatically based on the machine's cycle signal, ensuring a continuous material supply.
Q3: Does the system include a drying hopper and a dehumidifier?
A: Yes, the complete line includes a dehumidifying dryer (desiccant or compressed air type), an insulated drying hopper, a vacuum loader, and a discharge unit. All components are pre-configured for easy installation.
Q4: What is the typical drying temperature for PET?
A: PET usually requires drying at 160-180°C for 4-6 hours. Our line can achieve up to 180°C, and the dew point below -30°C ensures effective drying.
Q5: Can you customize the hopper size or voltage?
A: Absolutely. We offer custom hopper volumes from 100L to 2000L and can adapt power supply to 220V/60Hz, 415V/50Hz, etc. Just provide your requirements.
Q6: Is the control system easy to operate?
A: Yes, the standard controller is user-friendly with digital display and simple buttons. An optional PLC with touch screen provides advanced features like data logging and remote monitoring.
Q7: How long is the warranty?
A: Typically we provide a 12-month warranty against manufacturing defects. Extended warranty plans are available upon request.
Q8: What are the main markets you serve?
A: We export to North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, East Asia, Western Europe, Central America, Northern Europe, Southern Europe, South Asia, and also serve the domestic market in China.
