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.
A forged part is made from a chunk of metal. It is then usually heated, and it is pounded into shape in a forging die. The extra metal oozes out from between the forging dies and must be ground off. This is why there is a large wide parting line on forged parts. A forged crank is stronger because of the steel it is made from. It could be an alloyed 4340 steel with .40% carbon, or a weaker 1020 steel that is not alloyed and has less (.20%) carbon. The early Chevy forged steel cranks crack so regularly mostly because of the weak material they were forged from.
