Maximizing our Manufacturing

The Vertical Cable Cell Goes Lean…with Excellent Results.

Ralph Landis and Daniel Zook

Frankenstein

When Ralph Landis and Daniel Zook started in the vertical cable cell at Key-Link, they didn’t really have any number goals to meet. There was simply a stack of paper orders that the team would work through until they couldn’t; maybe the shift was over, or they were out of parts, or they finished today’s orders and had no new ones.

 

There were multiple team members, but no guidance about how much they should be producing.

 

However, in Key-Link’s journey toward being lean, as well as continuously improving, it became clear that the cell could operate in a much more efficient way. Landis and Zook, along with management, became invested in ways to produce more product, more efficiently, and with less waste.

 

One of the first massive improvements came with hard numbers. Instead of a stack of orders, Landis and Zook were challenged to output a certain amount of boxed railing per day. With that goal number in place, they began to look for ways they could meet and then increase their output goals. They knew what they needed, and they shared those needs with management.

 

First, they got rid of “Frankenstein.” This machine, which crimps the wire so a nut can be added to the end, was inefficient and hard to work with, and they nicknamed it Frankenstein because it had been welded together so many times. The new machine (which does not have a name!) is much faster and easier to use.

 

One of the principles of Lean is minimizing waste as much as possible. Movement is one kind of waste. A worker who takes only one step to reach a needed piece of product is more efficient than one who has to take twenty steps. With their move from one Key-Link plant to another, the vertical cable cell found themselves in a much less wasteful situation as they were able to move the railings and other pieces that they needed to within only a few steps of their cell, as well as adding shelving for additional storage. Now they don’t have to walk across the warehouse to get rails or other material.

 

But doing everything in their power was still going to be a problem if they couldn’t get the fittings they needed. Early on in their tenure, Landis and Zook did not always have the machined fittings required to put the vertical cable rail together. However, with the addition of new Swiss machines at Key-Link, fitting production increased and getting the pieces became much easier.

 

Because of their changes and in response to increasing sales, the cell has been able to double production to meet the demand.

 

Lean manufacturing is about continuous improvement, so there are more changes and upgrades to be made, but Landis and Zook are happy with the way things are improving and with their small but efficient team.

 

“I wasn’t sure about Lean when I first heard about it,” Landis said, “but when I saw the numbers we were doing, I knew it worked.”

Put a Ring on It?

An issue with the aluminum handrail joint ring—and how we’re going to solve it.

Have you used aluminum handrail from Key-Link? Have you used a P-loop return?

 

You might know that our P-loop return comes with a joint ring. The P-loop return generally fits into one of the straight handrail pieces, and the ring goes over the joint where the P-loop return meets the handrail. The ring helps minimize any roughness, and some customers prefer the look of the ring to the look of the small crack between the pieces.

 

Unfortunately, some of our customers who regularly use both the P-loop return and the joint ring noticed that the joint ring did not fit the P-loop return without a lot of effort, and we realized we needed to reevaluate this part of the system for quality assurance. The Quality team here decided to remove the ring until we could determine the best way to make it fit.

 

Since the joint ring works on every other part of the railing system, it makes more sense financially and logistically to re-make the P-loop return. After talking with our vendor, we’ve decided to make a new die for the P-loop return and start manufacturing a new part, and, if things run smoothly, we expect to have the new P-loop sometime in July. We will be supplying the original P-loop return without interruption until we receive the new version. The only significant change in the new version will be that it’s smaller in diameter and will more easily fit the joint ring.

 

In the meantime, if you would like a joint ring included in your handrail orders, please let your account representative know and we will happily send you the joint ring. If you do not need a joint ring, you don’t need to do anything more. Once we have the new p-loop return, the joint ring will once again be included in all orders.

 

Give us a call if you have any questions or if you’d like to request the joint ring.

All Aluminum

This year we’re switching to all aluminum handrail. We sat down with our lead product engineer to find out why

With the arrival of 2019 came the arrival of aluminum handrail for Superior Plastic Products. For Key-Link customers, aluminum handrail is old hat, but a lot of Superior customers have been used to vinyl secondary handrail.

 

As of June 1, 2019, we will no longer be selling vinyl handrail (with some exceptions). There are a couple of reasons for this. We sat down with Product Engineer Mike Alexander to get some answers about the switch.

 

Q. Why did we decide to switch everyone to aluminum handrail?

 

A. Aluminum handrail has a lot of benefits. In this case, our aluminum handrail is better in three ways. First, it’s ADA compliant. Second, it’s not only secondary handrail. You can use this system alone between two posts if you want to. And third, it’s code compliant.

 

Q. So it meets IBC and ICC codes?

 

A. Yes. It meets International Building Code requirements on 6-foot sections and International Residential Code requirements on 8-foot sections.

 

Q. When you say ADA compliant, what does that mean?

 

A. There isn’t a governing board that decides ADA compliancy the way there is with building code. However, this handrail meets the various clearance requirements and measurement requirements as specified in ADA documentation.

 

Q. What about colors? Does white aluminum handrail match white vinyl railing?

 

A. I think most people would be hard-pressed to tell a difference between the colors. We powder-coat the aluminum handrail to match the vinyl railing and the colors are almost identical.
