Unveiling! How Does This Injection Molding Machine Achieve Drying-Free Injection?
In the traditional injection molding production process, drying of plastic pellets has always been an indispensable step. Common engineering plastics such as ABS, PET, and PC often require drying before use, which not only consumes time and energy but also easily leads to material performance degradation. Zhoushan Hongtuo Machinery Co., Ltd. has developed an internal circulation dehumidification series injection molding machine, offering a more efficient and environmentally friendly solution to help customers simplify processes and reduce costs.

Product Advantages
✔ No need for drying, cost-saving
Traditional injection molding requires pre-drying of raw materials, while Hongtuo's internal circulation dehumidifying injection molding machine can mold directly, eliminating the need for drying equipment and electricity costs, reducing production steps, and lowering operating costs.
✔ Maintain the properties of raw materials and ensure stable product quality
Without the need for high-temperature drying, the plasticity and color of the raw materials are better preserved, avoiding property changes caused by excessive heating. The quality of the finished product is closer to the original state of the raw materials.
✔ Reduce dust, improve the production environment
The drying process tends to generate dust, affecting workers' health and equipment cleanliness. The Hongtuo internal circulation dehumidifying injection molding machine eliminates the drying step, reducing dust pollution, and making the production environment cleaner and safer.
✔ Easy to operate and highly efficient in production
The equipment adopts a standardized operating mode, compatible with ordinary injection molding machines without requiring complex adjustments, while optimizing the production process and improving overall efficiency.

Technical Principles
Based on traditional injection molding machine technology and processes, Hongtuo has developed a new generation of internal circulation dehumidifying injection molding machines. Using independently developed screws, it does not require auxiliary drying equipment. Through the internal circulation dehumidification system, moisture, volatile additives, and low molecular gas raw materials in the melt are directly expelled during processing, thereby achieving a drying-free effect.
For special engineering plastics that tend to generate small molecular volatiles during processing and require extremely low moisture content, an internal circulation dehumidification injection molding machine can effectively remove the gases produced during processing. This solution addresses the issue of product performance indices failing due to poor dehumidification and also avoids the high energy consumption problem associated with prolonged drying.

Application areas
In the injection molding industry, where all raw materials need to be dried to remove moisture before processing and production, the focus is on the processing fields of ABS, PET, PC, PA, POM, PMMA, engineering plastics, and moisture-sensitive biodegradable plastics.

Biodegradable plastic: Eliminate the necessary drying process, directly produce high-quality products, and make adjustments simpler.
2. Transparent plastics: Easily resolve common appearance defects in thick-walled products, ensuring product transparency.
3. Engineering plastics and high-temperature dehumidifying drying plastics: effectively remove small molecular volatiles and avoid the high energy consumption problem of high-temperature drying.
4. Recycled Plastic: Break through the limitations of traditional drying, significantly enhancing the gloss and performance of recycled material products.
