Advantages and Disadvantages of Assembly Line Manufacturing

Posted: December 28, 2012 in Uncategorized

Assembly LineThe assembly line was one of the key components of the Industrial Revolution. The principles of the assembly line allowed manufacturers to produce greatly increased amounts of products at lower cost and indirectly made for easier maintenance of products after their assembly. While the ideas behind assembly line manufacturing are a vital part of the way products are made and assembled today, it is also interesting to consider the disadvantages of these types of production systems.


For manufacturers, the benefits of assembly line production are enormous. An inherent part of the idea of assembly lines is that each item produced from a certain product line is as close to identical as possible. This allows quick and easy assembly throughout the process, and it also means that maintenance and replacement of worn or broken parts is a much simpler task down the road.

Prior to assembly line production, items were often made one at a time by hand by a single crafter. This meant that there were often great variations between one crafter’s work and the work of another crafter, and even among the products of a single crafter. If one part of a musket or tool were to break, it was no simple task to replace that part. Repairs and replacements had to be custom made to fit the specific item at hand.

With standardized, interchangeable parts being a key part of the assembly line process, the next generation of manufacturing did not suffer as much from those issues of difficult repairs. If part of a product breaks, it can easily be replaced with an identical part matching the item.

Generally speaking, assembly line production requires each person involved to only perform a small number of simple and specific operations, meaning training requirements are not very demanding, and nearly anybody can fill a spot on the production line in many cases. This allows companies to keep expenses low and easily replace employees who leave. The work is also pretty easy: chain, roller, or belt conveyors move products through the process, meaning no heavy lifting or moving is generally required of workers. In fact, specialized conveyors from companies like Cambelt often play a vital role in production facilities. Finding or creating the right conveyor for the job makes the whole process possible, as you can see at


The disadvantages of the assembly line style of production are the same qualities described above but looked at from another angle. While several workers using interchangeable, standardized parts makes for easy repairs and replacements, it also means each item loses that individualistic flare of unique craftsmanship. For some products, especially decorative or luxurious items, it can be very desirable to know that the piece was uniquely crafted by a single skilled and experienced artisan, who put a lot of heart and soul into the creation—not just a bunch of disinterested people on a production line slapping parts together with no personal investment in the quality of the finished product.

Other disadvantages of assembly line production are based on the worker’s point of view. Because little training is generally required, wages may not be very competitive. The work itself can also be extremely repetitive and monotonous, offering little in the way of mental stimulation and creative critical thinking.

The Right Production Styles for the Right Products

Because of the different strengths of assembly line versus traditional crafting production styles, different types of products are better suited for one style than the other. Where functional utility, easy maintenance, and low cost are expected, assembly lines are ideal. When unique craftsmanship or customized detail is desired, traditional crafting methods are the way to go.
