Scrap Reduction Using Lean Manufacturing and Six Sigma Tools.

In this article, you will learn what is a product reject and how to make scrap reduction using lean manufacturing and six sigma techniques.

Scrap Definition

Rejects or scrap is the discarded material from an operation suitable for reprocessing or not.

Scrap and rejects are byproducts of an inefficient process that promote rework activities.

Scrap can be very expensive, as it can be leftover materials in excess of those needed for an assembly, or could be an entire batch of parts outside tolerances that need to be reworked or recycled.

The Principal 7 Causes of Scraps, Rejects, and Rework are:

1. Machine malfunction
2. Human error
3. Poor quality materials
4. Weak designs
5. Specifications change not communicated
6. Inefficient quality systems
7. Lack of procedures and process understanding

These causes can be reduced and in most cases, preventable with the right processes, systems, and training.

Seven 7 Suggestions to Make a Scrap Reduction in your Manufacturing Operations.

1. Establish a complete BOM Bill Of Materials for each product.
2. Select the right raw materials and suppliers based on quality and not on price exclusively.
3. Perform a trusted cost and process analysis of your operations.
4. Implement a visual inspection system to detect components and product failures as soon as possible.
5. Automate the scrap movement and disposition.
6. Bring frequently training to your personnel.
7. Establish efficient communications between the design and production members.
