Identifying Glass Manufacturing Line Bottlenecks

When it comes to manufacturing, there’s always one area of the production line that seems to slow everything down. It’s typically referred to as a bottleneck, which by definition occurs when input (typically materials) comes in faster than the next step can use it to create output. Bottlenecks can happen at all stages of your facility, from production to distribution to fulfillment. If you can identify the bottlenecks and apply solutions to fix them, you can increase your glass manufacturing plant’s overall speed, productivity and ultimately your bottom line.

In an assembly plant, a bottleneck is fairly straight forward to identify by looking for the typical signs: backlogged work or lots of waiting (for people or for materials).  What’s not as easy is identifying the root cause of the bottleneck. Sakichi Toyoda, one of the fathers of the Japanese industrial revolution, developed the technique of the 5 Whys in the 1930s as a way to find the root cause of a production line issue. The 5 Why’s is a remarkably simple approach. Essentially, you ask “why” 5 times until you arrive at your root cause of a problem.

A simple example on a glass shop floor might be that orders are constantly in jeopardy of being late. Using the 5 Why’s, we would ask:

Issue: Orders are shipped late, causing potential customer issues


Products received to be shipped are damaged causing a delay waiting for more product to be produced

Why are products damaged?

Workers have to transport glass across the shop floor and breakage occurs

Why does breakage occur?

We don’t have proper glass handling equipment

Why don’t we have proper glass handling equipment?

Because we don’t know what we need and therefore no decision is made.

And there’s the solution. The root cause is a lack of decision making on purchasing equipment. The easy fix is to delegate the task to someone else, like Wakefield Equipment who offers a variety of glass handling solutions for bottlenecks throughout your production line and is well versed in what glass handling equipment can make the most impact at each stage of the manufacturing line.

Wakefield Equipment has helped thousands of customers clear their bottlenecks by installing new equipment like:
