Rolling equipment manufacturers talk about the impact of hot air circulation heating methods

What are the effects of the hot air circulation heating method on product quality and energy conservation in rotational molding equipment? The manufacturer of the rotational molding equipment will tell you.

Rotary molding equipment has been using hot air circulation heating method for a long time, but not many people have mastered its true principle and how to use it reasonably. The scientific and reasonable use of hot air circulation has a great impact on the quality stability and manufacturing energy consumption of rotary molding products. Based on the fact that most domestic rotary molding equipment is still in the imitation stage, few practitioners have studied and analyzed it seriously. This article focuses on introducing the temperature control of hot air in the hot air circulation The relationship between hot air diversion and deep chamber heating, as well as their impact on product quality and energy consumption.

 

 

In the manufacturing of rotational molding products, the hot air circulation is crucial for the quality and energy consumption of the products. The traditional oven type open flame direct heating is a simple and energy-saving heating method, but why is this heating method being used less and less now? Practice has proven that open flame direct heating does save energy, but it has fatal defects that prevent heat from evenly passing through complex mold surfaces, resulting in substandard product quality. To achieve uniform heat flow to the mold surface, a certain heat flow rate is required. In the open flame heating method, the movement of hot air is naturally upward, and to achieve high-quality products and energy-saving effects, a reasonable hot air circulation must be used, This results in a semi open flame hot air cycle and the hot air cycle described in this article.
