Oriental Cheng packaging share thick sheet blister PC transparent lampshade production process, please see the following content

pc transparent lampshade blister processing molding overall use of semi-automatic high-speed blister molding machine production, its basic principle is: Pull the rolled pc transparent sheet into the electric furnace oven and heat it to the softened state, then pull it to the top of the manufactured lampshade mold, the mold is moved up and vacuumed, the softened sheet is adsorbed to the surface of the mold, and the cooling water is sprayed on the surface of the formed sheet in a fog to harden it, the formed sheet is automatically pulled to the storage box, and the pneumatic cutter separates the formed sheet from the unformed sheet. To complete the whole process.



pc transparent lamp shade is a mask for LED fluorescent lamps. This is related to PC material performance, PC in addition to excellent electrical insulation, extensibility, dimensional stability and chemical corrosion resistance, but also has self-extinguishing, flame retardant and other advantages. PC material transparency up to 92%, strong UV protection; High hardness, good strength, not easy to damage, scratch. Heat transfer property; Good resistance to mechanical impact, excellent impact resistance, flame retardant, fire prevention. It has stable chemical resistance, dimensional stability, cold bending installation, heat and cold resistance, and long-term physical stability at -40 to 120 degrees Celsius. PC transparent lampshade beautiful appearance, light weight, save bracket, easy to install deeply.

PC transparent thick sheet blister molding processing is widely used, such as PC light box cover, machine cover, lamp cover, lighting cover, blister word, blister cover, blister ceiling light and so on.


1, due to the special physical properties of PC transparent material easy to absorb water, it is necessary to put the oven to bake for more than 8 hours in the early stage of blister to remove the moisture inside the PV plate.


2, the production of the mold, the surface of the fine mirror polishing, to prevent in the process of blister due to the mold surface uneven caused by the PC transparent products appear unaesthetic marks.


3, the vacuum blister hole above the mold should be reasonable and scientific, can not be large or small, but also must be in a prominent position, otherwise there will be holes on the product, affecting the beauty of the product.


4, due to the good thermal stability of PC material, it is not easy to burn soft, when heating the blister molding machine, we must master the temperature, otherwise it will not be in place
