Method for manufacturing progressive type decorative machine plates via punching

Abstract

Provided is a method for manufacturing progressive type decorative machine plates via punching. The method comprises the following steps: forming an optical solid film upon the substrate; printing patterns upon the optical solid film via flexible and transparent pressing die; and using a radiation source to solidify the optical solid film. Then both the substrate and the optical solid film receive punching processing. The instant stress of processing deformation of the optical solid film and the substrate can be gradually released by two times of the punching of different dies and two-segment type punching of the same die as well as two times of stroke punching / continuous progressive punching processing of the same die, thereby completely avoiding the chapping / deformation of the optical solid film during the processing process, maintaining the completement of the pattern on the surface of the finished products, and ensuring the pattern to be firmly attached to the substrate.

Description

technical field [0001] The invention relates to a method for manufacturing a progressive stamping-formed decorative panel, in particular to a casing suitable for devices such as home appliances, electrical products, and electronic products, or for vehicles, furniture, door panels, containers, etc. A method of manufacturing an exterior part. Background technique [0002] With the rapid development of science and technology, more and more styles of consumer electronic products have been developed. However, product appearance often becomes one of the main considerations for consumers to purchase. Therefore, the design and development of diversified decorative boards has gradually become one of the key points of the industry. [0003] The shells and boards of well-known electronic products are often pasted with decorative stickers or sprayed and colored to make the appearance present different visual feelings. In addition, with the improvement of texture requirements, metal s...

Problems solved by technology

[0005] However, when the well-known photocurable film and substrate are processed and formed (such as stamping), especially when the bending or forming angle is large, the connection between the photocurable film and the substrate is often caused by the difference in ductility between the UV glue and the substrate. The surface or surface is cracked, deformed, or even the UV glue is peeled off and damaged, which makes the process defect rate very high
