Rejection comes in DIE-786 (Hub, RR Axle Housing) whose material is steel. This is a product of Mark Auto who is regular customer of Samrat Forgings Limited. These rejections give bad impression to customer, and also there is waste of: 1. Money 2. Manpower 3. Machinery 4. Material If your customer is not satisfied then your production is waste, to make our customer satisfied we have to improve our quality. So I took this problem and try to solve this.
