Pengaruh Ketebalan Plat Kuningan terhadap Cacat Produk dari Proses Deep Drawing

Abstract

The process of making earrings requires a deep drawing process where the results of the deep drawing process often experience problems such as cracking, tearing, wrinkling, fracture, and spring back. These problems can affect the production process of earrings. Knowing the effect of the thickness of the C26000 brass plate with a thickness variation of 0.06 mm; 0.09mm; 0.12 mm for the type of product defects and the percentage of types of defects for each product thickness from the deep drawing process which is carried out based on the six sigma research methodology using the DMAIC approach. The most common percentage of deep drawing defects at a thickness of 0.06 mm totaled 88 defects with five types of defects namely cracking, tearing, wrinkling, fracture, and spring back. Meanwhile, at a thickness of 0.09 mm, 52 deep drawing defects occurred and four types occurred, namely cracking, tearing, wrinkling, and spring back. For a thickness of 0.12 mm with 20 product defects and two types of defects arise, namely wrinkling and spring back.
