How to Reduce Scrap in Manufacturing

What difference would it make in your shop if you could reduce scrap by 25% or more?

In manufacturing, some scrap is a natural consequence. However, that doesn’t mean you need to accept it—or at least, not all of it. There are ways to reduce the amount of scrap that you produce by using the right methods and technology.


The concept is simple: lower scrap means higher profit margins.


Scrap Measurement

When evaluating how to reduce scrap in manufacturing, the first step is to measure your level of scrap. It’s amazing how many manufacturers do this incorrectly or don’t do it at all. For example, some manufacturers measure scrap against sales revenues instead of production costs. But this doesn’t adequately represent the cost of scrap, as it will vary depending on monthly sales.


Here’s the formula that you should use when measuring how to reduce scrap in manufacturing: Gross Scrap / Cost of Good Produced.


On a project basis, manage your expected (budgeted) amount of scrap versus the actual amount of scrap. If there’s a discrepancy, that’s one of the first places to look. Then, measure improvement against your baseline when implementing control processes. Even if you deem the amount of scrap to be acceptable, that doesn’t mean it’s not worth investigating other process efficiencies. Any scrap, waste, or rework that you can eliminate leads to higher profits.


How to Reduce Scrap in Manufacturing

You can reduce scrap in manufacturing by implementing these five steps:

  1. Having qualified equipment and operators

  2. Eliminating information silos

  3. Having proactive management

  4. Having a scrap materials plan

  5. Having quality management software (QMS)

Having Qualified Equipment and Operators

When equipment and operators are properly qualified, scrap goes down. This means ensuring that equipment is calibrated correctly and that maintenance has been done. Poor maintenance habits and improper calibration will create additional scrap and potentially unsafe conditions.


Make sure your operators are also qualified for the task at hand. If not, the work may be sub-par. Your operators should be trained on the process and the equipment.

If they’re not scheduled at the same time that the equipment is available, it may slow your production schedule.


Eliminating Information Silos

Without real-time information available to everyone who needs it, scrap is inevitable. If you’re using a manual process or the wrong software, your operators may encounter these conditions that lead to increased scrap:

  • Outdated information is used.

  • Updated information doesn’t get passed on to operators.

  • Change orders and process changes are not documented.

  • Papers get lost or misplaced.

The right real-time QMS solution can solve these problems.


Having Proactive Management

If you have acceptable raw materials and stable machining, nearly every other problem tracks back to either human error and/or process problems. When there’s a large amount of scrap or you’re unhappy with the level of scrap, it means you need more proactive management. This should include:

  • Total quality management (TQM)

  • Corrective and preventative actions (CAPA) program

  • Qualifying programs

If you’re waiting until you catch nonconformance's to address quality, you have inefficient systems. A focus on TQM is a strategic and systematic approach to quality through processes. When this proactive quality management thinking is embedded in your culture along with CAPA and qualifying programs, quality improves and scrap reduces.


Having a Scrap Materials Plan

Some amount of scrap is simply unavoidable. Besides the cost of labor and rework, you’re also looking at materials costs. Instituting a formal scrap materials plan should examine:

  • Can products or components be refurbished or repurposed?

  • Can scrap be recycled?

  • How can you avoid dumping fees?

Your first thought for scrap should be repurposing. Re-using scrap metal, for example, is less resource-intensive than using virgin materials. Plastic can often be repurposed for component parts. Every piece of scrap that you can repurpose can save you money, versus having to pay for it be hauled away or dumping fees. If scrap can’t be repurposed, then make sure you’re recycling it to recover whatever costs you can.


Having Quality Management Software: How Bluestreak Helps Reduce Scrap
