According to the International Rubber Research Organization (IRSG), global demand for natural and synthetic rubber in 2013 may increase by 4% to 27.7 million tons from the previous year, as consumers begin to replenish their inventory. The IRSG's estimate is based on the International Monetary Fund’s forecast of a 3.9% global economic growth next year. The agency predicts that global rubber consumption in 2012 will be 26.6 million tons, which is lower than the previously estimated 26.8 million tons, but higher than the 2011 consumption of 25.9 million tons.

The IRSG is responsible for compiling data and publishing estimates of global rubber demand and supply, with 35 member states. The agency expects that China's rubber demand will increase by 4.6% next year, continuing the increase this year. China is the world's largest consumer of rubber, accounting for about 30% of the world's natural and synthetic rubber output. According to the latest IRSG estimate, China will consume 8.7 million tons of rubber in 2012, slightly higher than last year's 8.3 million tons. Global rubber production this year is expected to rise to 11.3 million tons, slightly higher than last year's 11 million tons.

The die casting process involves the use of a furnace, metal, die casting machine, and die.

The metal, typically a non-ferrous alloy such as aluminium or zinc, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting parts.

The castings that are created in this process can vary greatly in size and weight, ranging from a couple of ounces to 100 pounds. One common application of die-cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.

Metal housings for a variety of appliances and equipment are often die cast.

Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Most home appliances also need lightweight and firm aluminum die casting parts, like bracket, heat dissipation module or structural support. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
