Let It Flow.
TW Perry reorganizes its manufacturing facility to develop a clean-cut, more
efficient operation.
What do Toyota and building materials dealer TW Perry have in common" They both
use the same philosophy to drive their manufacturing setups. Called "lean
manufacturing," the philosophy aims to reduce waste during the manufacturing
process and centers on eliminating unnecessary steps. When drafting the plan
for TW Perry"s new 42,500-square-foot fabrication facility for its Classic
Moulding and Door division, Chris Gray, director of architectural sales, kept
this goal in mind. He ended up with a space that allows for streamlined
manufacturing.
"We wanted to eliminate as much of the movement as we could from one step to
the next, to cut down on wasted time between operations," Gray says.
The Classic Moulding and Door division, located in Savage, Md., performs a
variety of high-end tasks. It generates $5 million in annual sales by designing
and manufacturing custom doors, millwork, archways, fireplace mantels, and
radius casing, and also offers door hanging, PVC bending, CNC routing, and
Andersen window mulling. Gray started Classic Moulding and Door in 1995 as a
separate company that competed for the same customers as Gaithersburg,
Md.-based TW Perry.
In 2005, TW Perry approached Gray with a merger offer, and they joined forces.
Gray brought his expertise to the division, along with a lot of equipment and
personnel. After about a year, he decided to move into a larger facility,
making for the opportunity to redesign the manufacturing layout. In the old
shop, nothing was logically ordered, says Gray. The files were in one area, the
gluing in another, and the materials had to be hauled back and forth around the
shop. It just didn't flow.
They had limited space, he says, not enough room to make everything work. Before
getting started on a new layout, Gray and Darwin Davis, custom shop manager,
thought about how to direct materials through each manufacturing step. They
mapped everything in a flowchart, tried out the processes, and rearranged work
as needed to keep everything flowing. "We took it down to its simplest
movement, and looked at what the most efficient way was to move the parts and
pieces," Gray says. Each task was made into what Gray calls a cell. Gray and
Davis tried to group cells as close to each other as possible to minimize
material handling and increase productivity. After three months of trial and
error, they were happy with what they produced. "When we moved into the new
facility, we wanted our raw materials where we did our initial cutting and
surfacing. Each process is a couple of feet apart," Gray says. "Our lumber
moves very quickly through the processing system.... We keep everything close
to each other. ...That eliminates wasted time." Fleet trucks take products
directly from the shop to the jobsite, which saves time and ensures the safe
delivery of materials, TW Perry states in its entry binder. The new workflow
brought fast improvements. "We did immediately see quicker assembly times,
whether it was a custom product or a production product," Gray says. "If we
estimated 20 hours to do a job, we now got it done in 15 or 16 hours."
ProSales" judges praised the facility for its clean layout, quality control,
and self sufficiency of manufacturing. Because of the shop"s custom nature,
many tasks require hands-on activity and attention to detail. But adding new
equipment to a basic mix of table saws and shapers further increased efficiency
and profit margins. A CNC router took on the task of irregular shapes and
curves. Radius molding blanks cut from the router feed through a specialized
shaper, which profiles them into contoured molding. Modern door hangers machine
doors and jambs, and an oven warms and bends PVC moldings and boards. The
company's PVC facilities offer a quicker way to produce certain carved parts
and pieces, Gray says, along with making parts more durable for an exterior
applications.
The PVC can be ready to go in 15 minutes, while working wood into the same
shape could take four times that with less durability, he says. TW Perry also
gives customers tours of the facility. After a virtual tour of the space,
interested clients get to see the material in action and look at current
projects. "It has turned out to be a rewarding experience. The contractor has a
handson experience of what we"re doing," Gray says. "We see architects
specifying us on their plans because they see that we can make that specialty
product." Although the facility has brought
TW Perry success, Gray does not consider the process finished. He wants to
continue to use lean manufacturing to improve how his division performs. "Once
you get it the way you like it, work at it, and you can take out more areas to
save even more time," he says. "It will continue to change as you get better." - Victoria Markovitz
