Problems solved by technology

Since the conventional way of pulling the anodized aluminum is horizontal or vertical straight pulling during hot stamping, and the narrowest width of the anodized aluminum is generally 25mm, so when the bronzing pattern is small, the horizontal or vertical straight pulled anodized aluminum is only used in the middle of the anodized aluminum part, a large part of the anodized aluminum on both sides will be wast

Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The present invention provides a bronzing anodized aluminum cable-drawing method, which is mainly used to solve the problem that only the central part of anodized aluminum can be used for hot stamping patterns in the straight pull method, and the waste of anodized aluminum on both sides is relatively serious, the utilization rate is low, and the problem of hot stamping The number of printed patterns is small and the production efficiency is not high.

[0016] Wherein the bronzing anodized aluminum cable pulling method described in the present invention first judges whether the pattern shape ...

Abstract

The invention discloses a slant drawing method for gilt alumite. The method comprises the steps of: computing an slant drawing angle of the gilt alumite theta according to spacing of gilding positions a, width of gilding position b, length of gilding position c, spacing of gilding traces on alumite d, and according to a formula that theta is equal to arctan (b+d)/a; gliding a pattern on the alumite by gilding press according to the angle. For the gliding precuts with small patterns, the slant drawing method can greatly increase the use ratio of the alumite, reduce the production cost, meanwhile, also can shorten the distance for drawing foil in a jumping manner on the alumite, effectively increase the stability of foil drawing on alumite and improve the production efficiency.

Description

technical field [0001] The invention relates to hot-stamping technology of hot-stamping hot-melting aluminum, in particular to a cable-drawing method of hot-stamping hot-melting hot-melting aluminum. Background technique [0002] Anodized aluminum hot stamping is a very important post-press processing technology in packaging printing. It is mainly hot stamping patterns, characters, and lines to highlight the name, trademark and brand of the product, so as to beautify the product and improve the quality of the packaging product. Anodized aluminum hot stamping is also often used for post-press processing of hardcover book covers, cigarette cases, greeting cards and wall calendars. [0003] At present, the hot stamping process of anodized aluminum is as follows: the anodized aluminum is heated through the hot stamping plate, the peeling layer is melted, and then the adhesive layer is also melted. The aluminum and pigmented layers remain on the substrate. The width selection o...
