In the era of pursuing outstanding quality and green manufacturing, our company was the first to seamlessly integrate advanced vacuum drying technology into the heat setting process, solving many pain points of traditional processes. Not only have we enhanced product quality, but we have also reduced your overall cost, achieving a win-win situation of efficiency and environmental protection.
In high-precision manufacturing fields such as textiles, nonwoven fabrics, composite materials and new energy, drying and heat setting are the key links that determine the final quality of the product. However, are you still troubled by the many problems brought by traditional hot air setting?
The surface of the product feels hardened and has uneven color?
High energy consumption and difficulty in controlling production costs?
Are you at a loss when dealing with heat-sensitive materials such as high-end PTFE and carbon fiber prepregs?
Why choose "vacuum + heat setting"?
Traditional hot air drying and heat setting rely on high-temperature air convection, with heat transferred from the outside to the inside, which has inherent limitations. The vacuum environment, on the other hand, has brought revolutionary changes to heat treatment.
1. Ultimate quality, from the inside out
Under vacuum conditions, the boiling point of a liquid drops significantly. Moisture and solvents can evaporate rapidly at lower temperatures. This means:
No surface hardening: It avoids the formation of a "hard shell" due to overly rapid surface drying, allowing internal moisture to escape smoothly. The finished product feels softer and fuller to the touch.
Perfect uniformity: The vacuum environment provides an oxygen-free and convection-free uniform thermal field, ensuring that heat rises uniformly from the core of the material, eliminating color differences, temperature differences and internal stress, and achieving the ultimate dimensional stability of the product.
2. Significantly save energy and reduce costs while increasing efficiency
Low-temperature and high-efficiency: By using low-temperature vacuum drying, the energy consumption for heating a large amount of air from room temperature to high temperature is significantly reduced.
Waste heat recovery: Our system can efficiently recover the latent heat of water vapor condensation during the drying stage and utilize it for the subsequent heat setting and insulation stage. The comprehensive energy consumption can be reduced by 30% to 50% compared to traditional equipment.
3. Wide material adaptability unlocks unlimited possibilities
For sensitive materials that are prone to yellowing when exposed to oxygen and decomposition at high temperatures, a vacuum environment serves as an oxygen-free "protective shield". This makes it possible to handle high-end special fibers, biomedical materials, electronic films, etc., helping you explore the market for high value-added products.
4. New standards for environmental protection and safety
The entire process is carried out in a closed vacuum environment, effectively controlling the disorderly emission of VOCs (volatile organic compounds), facilitating subsequent centralized treatment and meeting increasingly strict environmental protection requirements. At the same time, an oxygen-free environment also eliminates the risks of dust explosions and material oxidation, making production safer.
We are not merely equipment manufacturers; we are also your advisors for process upgrades. Our vacuum heat setting integrated solution offers you not just a machine, but a complete platform to enhance product competitiveness, reduce operating costs and achieve green manufacturing.
