Mechanical sign manufacturers introduce the five processes of production process of sign

Mechanical sign manufacturers to introduce the five processes of production process of sign: 1, molding of sign making the machining molding after spray paint, make its installation dimensions unified specification and batch production. Instrument painting panel processing - to size requirement - - - - - - > sign machinery manufacturers introduce sign manufacturing process of the five processes: 1, molding of sign making the machining molding after spray paint, make its installation dimensions unified specification and batch production. Spray paint panel processing instrument for a strict size requirement, need to have experience of pliers, millers, conditional nc drilling machine can be used. 2, oil removal: sign in order to make the surface of aluminum plate for printing coating has the certain affinity, to remove the oil on the surface of the plate, generally encapsulated oil can use first soft sawdust wipe, then use organic solvent to oil; Machining of oil available organic solvent or alkaline solution chemical degreasing. Sign machinery manufacturers introduce sign manufacturing process of the five processes: 3, polishing: plate surface scratches, should first put a layer of putty, make it smooth, and in accordance with customer requirements is the mechanical polishing, chemical polishing, choose or electrochemical polishing. 4, spray primer: due to the combination of aluminum alloy material and paint, printing ink sex is bad, the aluminum alloy panel before spray paint to spray a layer of about 0. 01 mm thick epoxy zinc chromate primer. 5, and spray paint: according to the customer's requirements, spraying color corresponding amino paint and acrylic paint. For light color paint, especially white paint, the drying temperature and drying time should be controlled strictly, yellow or white paint.
