Embodiment 1

[0026] This example is used to illustrate the method provided by the present invention.

[0027] First, PC plastic is injected into the plastic parts, and the back of the plastic parts is hollowed out and printed with black CAV ink twice, and then KPL-150 hot stamping paper is selected, and the temperature in the hot stamping machine is 210±10°C, and the time is 2±1S hot stamping processing , to obtain a plastic part covered with an aluminum layer, and then print Japanese Seiko, MIB-001 type varnish on the aluminum layer, and then spray transparent colorless UV paint on the front of the plastic part, and punch to get the button particles.

Embodiment 4-6

[0033] The 100 mobile phone button samples obtained in the above-mentioned embodiment 1, comparative example 1, and comparative example 2 were subjected to the following appearance inspection and performance inspection to determine the yield rate of the product, and compare its processing costs at the same time. The results are shown in Table 1.

[0034] Product Yield Calculation

[0035] Product yield (%) = number of qualified products / number of all products

[0036] The qualified products are all qualified products through QUV test, damp heat cycle test, neutral salt spray test, vibration wear resistance test and appearance inspection.

[0037] QUV test: 340nm, 0.63W / m2, UV light for 96 hours, the appearance and function of the sample, confirm that its basic mechanical and electrical properties are normal.

[0038]Damp heat cycle test: maintain 25°C, humidity 95%, rise to 55°C within 3 hours, humidity 93-96%, maintain 9 hours at 55°C, then drop to 25°C within 3 hours, hum...

Abstract

The invention provides an electronic product key, which comprises a key body and a partially-hollowed printing ink layer positioned on the back of the key, wherein the hollowed part is provided with a character pattern. The electronic product key further comprises an aluminum layer at least covered on the hollowed part of the printing ink layer, and a gloss oil layer covered on the aluminum layer, wherein the gloss oil layer is used for protecting the aluminum layer. The invention also provides a key manufacturing method. In the method, hot-stamping technology is applied to a key decoration process, so the plastic key can achieve the appearance effects of good metal texture and high luster and is endowed with relatively higher economic value, the cost of PVD or mirror printing ink for achieving the effects is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an electronic product button and its manufacturing process Background technique: [0002] At present, the plastic keys of electronic products are usually produced by printing (or spraying) ink on the surface of the plastic keys, and then carving off part of the ink with laser to form characters, and the finally obtained product has a single decorative effect. In order to achieve high-quality, high-gloss decorative effects, the industry generally adopts the physical sputtering coating (PVD) method or inks with special mirror effects. The PVD process is not stable at present, and the products produced have many impurities, while mirror inks are relatively Thin, difficult to operate, and the ink itself is easy to block the screen during screen printing. These two methods have high process costs, high requirements on environmental conditions, great difficulty in implementation, and low product yields, which lead to high product co...
