Production. art is there are production technology complexity, and defect rate is high, high production cost, and the dust generated in production process be easy to cause environment
The problem of pollution and damage human health.
The embodiments of the present invention are implemented as follows, a kind of aluminium alloy packing box production technology, comprising: to aluminum alloy plate materials into
Row surface removal of impurities processing, the aluminum alloy plate materials after being cleaned；
One layer of tempered oil film is coated on the surface of the aluminum alloy plate materials after the removal of impurities and is dried, and aluminium to be printed is obtained
Sheet alloy, wherein the dosage of the tempered oil film is 3g/m2~5g/m2；
According to preset printing technology, preset pattern is stamped on the surface of the aluminum alloy plate materials to be printed, and
10~15min, the aluminum alloy plate materials after being printed are toasted under the conditions of 160~170 DEG C of temperature；
The surface that aluminum alloy plate materials after the printing are printed on predetermined pattern coats one layer of tempered oil film and dries, and obtains
The aluminum alloy plate materials of surface treatment are completed, wherein the dosage of the tempered oil film is 10g/m2~15g/m2；
According to preset bending molding process, bending is carried out to the aluminum alloy plate materials for completing surface treatment and forms packaging
Box.
The embodiment of the present invention also provides a kind of aluminium alloy packing box, and the aluminium alloy packing box is raw by above-mentioned aluminium alloy packing box
Production. art is made.
Aluminium alloy packing box production technology provided in an embodiment of the present invention is omitted in traditional aluminum alloy surface treatment process
A large amount of manually-operated polishing sandblasting oxidation treatment steps are needed, and traditional surface treatment procedure is changed to aluminum alloy plate materials
Surface clean, printing, coating tempered oil film processing are carried out, the complexity of production technology is reduced, saves a large amount of manpower money
Source and production cost, while the dust of traditional polishing sandblasting oxidation processes generation is avoided caused by environmental and human health impacts
Damage；Furthermore after the process of bending and molding is placed on surface treatment procedure, done at surface again after solving traditional molding
Reason, the problem of because being deformed caused by the factors such as the pressure of surface treatment, hence it is evident that reduce defect rate；And to aluminum alloy plate materials
The color on its surface can be made more bright, diversified after carrying out surface clean, printing, coating tempered oil film processing, surface is consistent
Property it is good, compensate for the single defect of traditional handicraft surface oxidation color, meet the increasingly diversified demand of people, improve aluminium conjunction
