“The
competition has always been here, it’s just a matter of where it’s
coming from. How do we become more important to our customers?”
Other
challenges in manufacturing come from closer than China. California has
high employee health benefits, high insurance rates, very high workman’s
compensation rates and city, state and federal regulations regarding air
quality, storm water, OSHA standards, waste management, business permits,
hazardous material handling and taxes.
One
of the largest manufacturing gains has come, surprisingly, from v-grooving.
“Every
hand you have to add to the product adds a lot of cost, particularly on
the benefits side,” Sweet says. “We look at the product and question
how we make it.”
The
idea behind v-grooving was started in 1995. There are far fewer parts and
steps along the way. Parts go from panel saw to boring to v-grooving.
Currently, 65 percent of casegoods are v-grooved on Auto V Grooving AVG
72UM and LVG4SF 48-inch machines. V-grooving eliminates 20 percent of
labor and 4 to 5 percent of materials.
“At
that point, our product becomes much more competitive,” Sweet says.
“It gets us a spread for a whole set on the retail floor of as much as
$100 or more.”
Sandberg
gets about 93 percent yield on its sheet stock. Sweet says new machinery
provides those yield gains, but engineering and other functions have to be
that much more accurate.
“If
the goal is 93 percent and you’re getting 88, you’re causing a problem
someplace. If you give away 5 percent, you’ve given your competitors an
advantage.”
Product
flow
Sandberg
has four buildings with 300,000 total square feet in Vernon, an industrial
suburb near downtown Los Angeles. The company buys particleboard and MDF,
mostly from West Fraser Mills and Sierra Pacific and does its own paper
and foil laminating on a Black Brothers TB-60 press line. Sweet says
almost everything is made here, except for a few components, carved
pieces, appliqués and hardware that are outsourced.
Basic
product flow starts with laminating, then on to the panel saw, CNC routers
and point-to-point machines, foilers
and edgebanders, boring and dowel insertion, double end tenoners or
v-grooving, dovetailing, finishing, sembly
and transfer to finished goods.
Laminated
panels are cut on two Schelling panel saws, an AL330/180 angular panel saw
and an FL 430 CNC rear-loading panel saw. A Giben angular panel saw is
used separately.
Cut
panels are routed on two Shoda 516-2462 twin table CNC routers and a Shoda
CNC shuttle table router. A
Busellato Super Junior 60 point-to-point machining center and a Busellato
feed-through boring and dowel insertion line are also used, along with a
Delmac FAM feedthrough boring and dowel insertion center.
One
Fletcher FT flat foiler and seven FM45 contour foilers are used for edge
work, along with a Holz-Her Triathlon 1414K CNC single-sided edgebander
with Doucet automatic panel return conveyor.
Other
equipment includes a Multiscore panel gang rip saw, two Tyler dovetailing
and boring centers and Nichols cleat cutoff and boring center.
The
finishing line is a custom Uvcured 100 percent solid double roll coat,
automatic spray and cure finishing line. The line, running since 1995, is
another important manufacturing upgrade. Components are roll coated,
everything is finished and then assembled.
The
flatline can eliminate VOCs, but Sweet had to reengineer the product line
so pieces can be finished first, then assembled. In 1990, emissions were
220 tons. Since 1990 emissions were reduced by 92 percent.
“We
were the first wood production facility in the Los Angeles basin to
implement water-based topcoats, in 1991,” he says. “And the first
woodworking facility to install a 100 percent solid, zero VOC, UV-cured
finishing line, in 1995.
“We
continue to investigate new finishing materials and systems to further
reduce our emissions.” There are six assembly lines, with three Comil
automatic feedthrough case clamps and four Nichols layback machines for
packaging the bottom of a carton. Bed assembly is done in another
building.
All
of the 450 employees are crosstrained. The finishing people are
crosstrained into assembly. Assembly people are cross-trained in different
product lines.
“More
and more we’re looking for ways to eliminate non-value-added labor. If
an operation is not adding value, how do we stop from doing it?”
Future
Plans
Future
plans include more efficient machinery. “You can’t wait to buy it,”
Sweet says. “You have to keep reinventing yourself, equipment and
training to make people smart and safer.”
First
on the list are additional Vgroovers, so the entire product line will be
changed over to V-grooving. Then a new cut-off saw line, moulder and
double-end tenoner will be added. The oldest building will be torn down
and space will be added to an existing building, on this site, for
assembly.
Sweet
is also trying to figure out how to bring robotics into the plant, to
reduce carpal tunnel injuries from stapling and screwing. An automatic
case clamp also will be added, and material handling will be
improved.
“Some
labor is not going to be eliminated, but repetitious labor has to be made
easier or eliminated.
“We
have to make sure that we’re making product that’s of value, that
sells on the store floor,” Sweet says. “And when a customer has a
problem, responding to him. That relationship has to become stronger.
Also, my vendors have to become an asset to me, selling me something that
will make me better.”
“You
have to be willing to adapt to change,” says Sandberg. “What can we do
to build a better product and be a better company?”
“Furniture
you want when you want it,” Sweet says. “We better make sure what
we’re designing is what our customers want.
“The
Sandbergs have said, that sign out front says Sandberg Manufacturing Co.,
it doesn’t say Sandberg Importing Co., or Sandberg Marketing Co.,”
Sweet says. “They’re proud of that manufacturing statement.”
