CKD, SKD and CBU: All About Knock Down Car Production

Semi knock down (SKD) This is a car production strategy where the origin factory ships parts of cars rather than the final product. The destination plant finishes the assembly and undergo quality inspections and testing before the sale. By using SKD kits, the company can concentrate the bulk of its production process in fewer factories.

From Ore to Finished Product

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
