1.Electroplating technology
First of all, it is the plating technology of buttons, which can be divided into hanging plating, barrel plating, continuous plating and brush plating, etc., mainly related to the size, volume and requirements of the parts to be plated. The principle of plating is that in a bath with plating solution, the part to be plated is cleaned and specially pretreated as the cathode, and the anode is made of plating metal, and the two poles are connected to the negative and positive terminals of the DC power supply respectively. The plating solution consists of an aqueous solution containing compounds of the plating metal, conductive salts, buffers, ph regulators and additives. After being energized, the metal ions in the plating solution, under the action of potential difference, move to the cathode to form a plating layer. The metal from the anode forms metal ions into the plating solution to maintain the concentration of the metal ions being plated. In some cases, such as chromium plating, an insoluble anode made of lead and lead-antimony alloy is used, which only plays the role of transferring electrons and conducting current. The concentration of chromium ions in the electrolyte depends on the periodic addition of chromium compounds to the plating solution to maintain it. When plating, the quality of the anode material, the composition of the plating solution, temperature, current density, energizing time, stirring intensity, precipitated impurities, power waveform, etc. all affect the quality of the plating layer and need to be controlled at the right time.
2.Inscribing technology
The next is the button engraving technology, earlier this technology is most used is mechanical engraving, but so engraved out of the button handwriting and pattern clarity is greatly restricted, especially when the need to engrave fine fonts or patterns, clarity is poor. Since the early 1990s, the development of automatic laser engraving button machine, this problem is solved. Automatic laser engraving button machine using computer scanning mapping, no matter how complex the pattern can be easily engraved on the button. At the same time, the laser beam used for engraving can be as fine as a few millimeters, so even the very fine handwriting or strokes can be clearly engraved.
3.Dyeing technology
Another is the button dyeing technology, button dyeing is generally cold lack of dyeing, there is a high temperature dyeing. Hardware button dyeing needs to do first forming, and then remove oil, and then spray oil, and finally over the oven can be. Plastic button dyeing is more simple, there are molds, plastic with good, press forming is complete.
Skilled operation of the button production and processing technology, not only can make the perfect shape of the button, high-quality buttons can also deepen the reputation of the enterprise, to do customer retention.
