Embodiment Construction

[0016] This product is the roof NCV2 of Fujian Daimler, and its process steps are as follows:

[0017] 1. Steam heating: use a steam boiler to heat, so that the steam pressure in the boiler reaches 10Mpa, and the steam temperature is 175±5°C, so that the steam rushes into the spun cotton being formed, and the color of the spun cotton changes from yellow to white , at this time, it means that the steam has achieved the effect.

[0018] 2. Compression molding: Put the back-spun cotton into the mold, and use the press to form the initial product; when pressing, the temperature of the upper mold: 180~190℃, the temperature of the lower mold: 180~190℃, and the molding pressure: 10.5~ 11.5mpa, molding time: 80~120sec;

[0019] 3. Cooling and shaping: Put the pressed and formed primary product (at room temperature) on a cooling jig with vacuum adsorption function for cooling and shaping, cooling time: 55-65 sec; the function of vacuum adsorption is to keep the product in its original...
