Among them, the German chemical giant BASF once again ranked first in the world's chemical industry top 50 with US$70.5 billion in chemical product sales. This is the company's sixth consecutive year ranking. The vast majority of the company's profits do not come from the chemicals business but are contributed by its Wintershaw oil and natural gas exploration business. Dow again became the second largest chemical company in the world. The company’s sales in 2008 reached US$58 billion, an increase of 7.5% over the previous year; however, its profit index fell sharply by 44.1% from the previous year to US$2.2 billion. In the third place is still the British Ineos Group, its sales revenue in 2008 was 47 billion US dollars, a huge contribution to the refining business. Shell's ranking was relegated from the third in the previous year to No. 11 because this year's statistics deducted sales revenue from its non-chemical business.
Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
