Benefits of technology

This new process uses an antimicrobial solution called KH-503 for cleanup after painting or other surface preparation steps like sand blastings. It helps prevent bonds from forming due to excessive pressure during manufacturing processes that can cause defects such as cracks when painted surfaces are used instead of being painted directly onto them.

Problems solved by technology

Injection Molded Product (IML) manufacturing processes that involve injecting molten material into an open cavity formed by two parts joined together at their edges, there may be issues like joint line formation due to imperfections caused by excessive heat used for melting the metal before it reaches its destination inside the machine tool itself. Additionally, painted areas can cause unevenness when applied over time leading to poor quality appearances. Therefore, this problem needs to be solved through various methods including cleanings and painting techniques.

Embodiment Construction

[0010] Please refer to Fig. 1, which is a schematic diagram of spraying of the present invention. The present invention mainly includes several spray guns 10 , several plastic parts 20 , several jig rods 30 and a ground rail cable 40 .

[0011] Wherein, the plastic parts 20 are plastic parts selected after injection molding, and the sprayed surface has obvious defects such as joint lines, air marks or mold marks, and each plastic part 20 is fixed on one end of each jig rod 30 , and the jig rod 30 can rotate around itself, and the other end of the jig rod 30 is fixed on the ground rail stay wire 40, and moves forward at a constant speed along the ground rail stay wire 40. In addition, the spray gun 10 is fixed and suspended above the plastic part 20.

[0012] The steps of the treatment method before the coating of the plastic part of the present invention are as follows: first, the anti-marking water is prepared, the main components of the anti-marking water are white oil and thi

Abstract

The invention provides a treatment method of plastic part before coating; wherein, the treatment method mainly comprises the following steps: firstly, mark removing water with corresponding strength is prepared based on defects such as joint lines, gas marks, mould marks, and the like, on the plastic part; then the coated surface with defects on the plastic part is completely sprayed with the mark removing water; finally the plastic part is spayed with paint. The treatment method of the plastic part before coating adopts the mark removing water to spray before painting, and the main components of the mark removing water are isopropyl alcohol and a diluent. The treatment method effectively treats the defects such as joint lines, gas marks, and the like, on the plastic part, thus avoiding appearance difference among plastic parts caused by artificial snagging and improving the adhesion of paint on the plastic part.
