Mass production is the manufacturing of a large number of similar products using an efficient means. It often incorporates the use of automated processes and machinery and is highly repetitive. This article will discuss the definition and history of mass production, the five phases of production, and its advantages and disadvantages.

What Is Mass Production?

Mass production uses specialized division of labor and automated processes to achieve high-volume manufacturing at a low cost. The use of specialized divisions of labor and automated machinery streamlines the manufacturing process resulting in increased efficiency. A highly efficient process will drive down costs.

However, these principles are only effective when manufacturing standardized parts. Any custom parts will deduct from the efficiencies gained by automated machinery and a specialized workforce. Mass production is linked with the moving production line, and modern mass production is linked back to the start of the industrial revolution. One of the best examples of mass production is in the automotive industry. Prior to mass production, when assembling a car every part would be brought to the car one by one and installed. Post Henry Ford’s moving production line for the Ford Model T, cars now move along the factory to the parts, whilst having multiple parts installed at once. Mass production is also known as: flow production, repetitive flow production, series production, and serial production.

The History of Mass Production

The use of specialized labor can be traced all the way back to ancient Greece. However, the most obvious examples of special manufacturing processes for mass production were first seen in the textile industry in 18th-century England whereby increasing the width of weaving textiles resulted in a higher rate of production. 

18th-century England marked the beginning of the Industrial Revolution in which mass production was first used on a large scale. One key development that led to the use of mass production was the use of James Watt’s improved steam engine which replaced humans and animals as an energy source. This improvement to the harnessing of steam energy allowed for the use of heavy machinery in production on a mass scale. 

In more recent history, Henry Ford is recognized as the first person to use a moving assembly line for mass production. The use of a moving assembly line meant that workers had specialized jobs. This reduces the time taken for workers to move from one task to another; instead, they repeat one job continuously. This style of production allowed Ford to keep up with customer demands while keeping costs low. As a result, the Ford Model T is one of the best-selling cars of all time, with 16.5 million sales. 

The Process of Mass Producing a Product

The steps taken to produce something on a mass scale are different from creating small production batches. That is because large-scale production methods, such as injection molding, require processes that produce consistent-quality parts for many batches. Consideration also needs to be given to the efficiency of the design when produced on such a scale, i.e., can post-processing and waste material be reduced? There is a defined process to follow when producing parts on a mass scale. There are five steps to mass production, as listed below:

Concepting

Creating a well-thought-out concept is the most important step in producing a product on a mass scale. The concept of a product forms the foundation for all the other production steps. If the concept is flawed, it will be hard to resolve in the latter stages. Creating a concept may be simple if the manufacturer has received a customer design specification. More commonly with mass-production parts, companies must carry out due diligence to understand the market, costs, risks, and rewards of the project before going ahead. To complete this stage, input from all departments may be necessary including engineering, sales, marketing, and senior management. 

Turning a Concept Into a 3D CAD Model

Once a concept is established, a 3D CAD model can be created. There are many different examples of CAD software available, and the one used will depend on the project requirements. This step can also be outsourced if necessary. The use of 3D modeling software has improved all production processes due to its ability to assess a design before it is made. 3D models can be tested using finite element analysis (FEA) and computational fluid dynamics (CFD) which can predict mechanical and fluid properties respectively, as well as other properties including weight and strength. Specialized tooling designed for the manufacturing process can also be designed in CAD for use in mass production.

Prototyping

Now the product has been modeled, it is time to build a prototype. Creating a prototype is still necessary even with computer modeling software as computer models don’t always agree with real-world applications. There are many variables in the manufacturing process that can produce results that are different from those predicted by a computer model. Prototyping is as much about testing the process as testing the product itself. Currently, 3D printing is being used in many prototyping scenarios as it can produce a cheap one-off part for testing before investing in tooling for mass production. Other processes that can be used to produce prototypes include CNC machining and casting. However, these methods of production will not produce a part with the same properties as injection molding which is one of the most popular mass production methods. 

Test Your Product on the Market

Testing your product is crucial before committing to mass production. Creating a limited run will give you a population sample from which you can identify the quality and performance of the product against the design criteria. The testing from this stage will provide feedback on the product which usually leads to an adjustment at the conceptual, 3D modeling, or prototyping stages of the project. It is crucial that any problems arising are fixed here before moving on to production. 

Mass Production

After completing the last four stages, the product is ready to be mass produced. Now, all of the tooling and materials need to be procured. With production on a mass scale, this is usually a major initial investment as large quantities of materials are required and high-performance machinery and tooling are needed that will last a large number of cycles with minimal failures. During mass production, the manufacturer must implement a quality management system to ensure quality does not degrade over time.

Advantages of Mass Production

Listed below are the advantages of mass production:

  1. Low Cost Per Part: This is due to the cost of overheads and expenses being spread over many parts. In addition, labor costs are minimized with the use of automated processes. 
  2. Consistent Quality: Mass-production parts are consistent in quality due to the repetitive nature of the production process. Mass-production parts are also of high quality, but usually, bespoke parts can offer a better quality, that is if cost isn’t a limiting factor.
  3. Fast Production: While it does take a long time to start a mass-production product and production line, the result is a high volume at a fast pace.
  4. Scalable Production: Not only is the production rate in mass production fast but it can also be scaled up easily to increase the production capacity. 
  5. Increased Productivity: Due to the repetitive nature of the tasks in mass production, the process can be iteratively improved to increase productivity to a maximum. 

Disadvantages of Mass Production

Listed below are the disadvantages of mass production:

  1. High Initial Investment: Mass production requires a large layout to buy all of the tooling and materials ready to start the production process. 
  2. Expensive Machine Downtime: In mass production, machines often work continuously to produce parts. If any point in the system fails, the product grinds to a halt and loses the project money in potential earnings. This can be mitigated with maintenance and planning, but it will still occur. 
  3. Altering the Design or Process Can Take Time and Money: Once set up to make a specific part, any deviation from the original design may require changes to all of the equipment, machines, and processes already set up. 
  4. Repetitive Work Can Disenfranchise Employees: Often staff will quickly become bored of carrying out repetitive tasks. This can lead to high staff turnover which can result in downtime and recruitment costs. 
  5. More Product Recalls: Any quality issues will likely be replicated in each product. The product may be sold many thousands of times before the realization that the product is faulty, resulting in large product recalls.
