Soil solarization. Follow these four steps to solarize your soil: cultivate and remove plant matter; level and smooth the soil; irrigate; and lay a clear tarp on the soil surface for 4 to 8 weeks, depending on local conditions.
Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. 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 aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine.
Cast iron is a member of iron-carbon alloy family with the carbon content greater than 2%. It is one of the oldest ferrous alloys used in construction and outdoor ornaments. It is hard, brittle, nonmalleable and more fusible compared to steel. But properties slightly vary depending on the composition of the material.
