Commonly used stent row recessed led downlights package, the stent row of copper or iron metal materials made by the precision die stamping, copper is more expensive, the cost naturally, by the fierce market competition factors, in order to reduce manufacturing costs, the market mostly cold-rolled low carbon steel stamping led high bay bracket irresolute stent row of iron to go through a silver-plated, silver has two roles, first in order to prevent the oxidation of rust, is to facilitate the welding, the stent row plating quality is critical it relates to the life of the recessed led downlights in the plating before processing should strictly follow the rules, rust, oil, phosphate, and other processes should be meticulous, to control current in the plating, silver plating thickness control, the coating is too the high cost of thick, too thin to affect the quality.
recessed led downlights packaging companies do not have the ability to test stent row plating quality, which gives a number of electroplating enterprises can take advantage of the silver layer thinning of the bracket of the plating row, reduce costs, and general packaging companies IQC stent row inspection means lacking, not detected stent row of coating thickness and the fastness of the instrument, and was easier to muddle through. I have seen some bracket emissions in a warehouse a few months after the rust, Do not say, we can see how bad the plating quality. Row of the products made out of this bracket is certainly not last long, not to mention the 30,000 to 50,000 hours, 10,000 hours is a problem.
