Teflon high temperature drying tunnel

Product Features: 

The design concept of this drying tunnel is ultra-wide standard type. It adopts 1200mm stainless steel (including large roller chain) spiral mesh belt, professional stainless steel rail, internal stainless steel liner fully enclosed and slitted, partially open structure.

The drying tunnel design includes: inlet zone, passive leveling preheating zone, high temperature sintering zone, rapid cooling zone, and exit zone. 8 sets of all-intelligent computer temperature control system, 140KW full stainless steel long-life electric heating tube heating system, mesh belt variable frequency shifting system, designed maximum working temperature temperature rise 420 °C, the best working speed 1500mm / min. The upper and lower sides of the drying tunnel are designed with independent air inlet and outlet air ducts, and the top is equipped with a water-cooled hot air mixing mechanism. The temperature zone in the high temperature zone is very uniform, and the temperature curve requirement of DuPont non-stick paint is obtained. It is suitable for aluminum parts with high quality and iron parts.

 Spray cleaning machine

Product Features: 

This equipment is made of stainless steel except for the drying tunnel and cooling system.

Import (handle the workpiece into the mesh belt)→60°C NaOH degreasing high pressure spray type degreasing→60°C hot water washing→washing away residual NaOH and oil→water rinsing→replenishing water→air curtain→acid washing (HF) → Hot water washing → Water rinsing → Replenishing water → Air curtain (to prevent water from entering the drying tunnel to improve drying efficiency and reduce water marks) → Drying → Cooling → Export

The optimal design speed is 800~1200/hour. That is, the mesh belt speed is 1500mm/min, and the highest workpiece can be washed 200mm (speed stepless adjustment)

The air curtain adopts high-pressure fan and electric lifting, which makes adjustment easy and reliable. And greatly improve work efficiency and save work costs
