Teflon sintering is poly (tetrafluoroethylene)An important step in the molding process of polytetrafluoroethylene products, which will cause fundamental changes in the performance of polytetrafluoroethylene products. The different process conditions such as sintering temperature and cooling rate directly affect the molecular weight, crystallinity, and porosity of the product. And these three factors also affect the physical, mechanical, and electrical properties of the product. At the same time, the quality of the sintering process also affects the magnitude and distribution of residual stresses in the product. Therefore, improper control of the sintering process will lead to product warping, deformation, and cracking. The PTFE sintering furnace produced by our company has good temperature uniformity, high automatic program control, and stable performance, making it an ideal specialized equipment for sintering PTFE products.

Performance characteristics:

1. High temperature uniformity: Imported high-precision 6-channel or 12 channel temperature monitoring recorders can be configured according to customer needs, displaying and recording the actual working temperature of each point in the furnace throughout the process.

2. High temperature control accuracy: The main temperature control adopts an intelligent program temperature controller, which can program multiple segments, with PID self-tuning, SSR solid-state relay+frequency controller power adjustment, and automatically completes the entire sintering process; Tunnel type sintering furnace can be divided into multiple temperature zones for temperature control, making the temperature in the entire working room more uniform; During the cooling process, the temperature can be lowered according to the process curve program. The sintering furnace is equipped with a cooling fan, and the air inlet automatically controls the opening angle of the air door. The air outlet is equipped with a fully automatic exhaust valve. The entire oven operation is controlled by PLC, and the sintering process is fully automated.

3. Reliable quality stability: The blower motor, impeller, and electric heating are all made of high-temperature resistant materials, which can adapt to continuous operation 24 hours a day without stopping. The quality is stable and reliable, with low noise and no shaking of the furnace body.

4. Convenient maintenance and repair: Parts such as fans and electric heaters are standardized and modularized according to different sintering furnace structures to make fault diagnosis more accurate, and parts maintenance is more convenient, timely, and cost-effective.

5. This equipment is a highly uniform and reliable sintering furnace specially designed and manufactured based on the extremely high requirements for uniformity in the furnace during polytetrafluoroethylene sintering. It is widely used for pre sintering, sintering, and shaping of polytetrafluoroethylene rods, plates, pipes, and powders.
