| When DaimlerChrysler Corporation decided to
produce the segment-busting Chrysler PT Cruiser after receiving rave reviews of the Pronto
Cruizer concept car in 1998, it needed a manufacturing site with sufficient capacity,
flexibility, productivity and a trained work force to bring a high-quality vehicle to
market quickly, at a low cost and with no loss of production during its launch. Faced
with this challenge, and operating near full capacity at its manufacturing facilities, the
Toluca Assembly Plant met the criteria, plus had the capacity and track-record that made
it the ideal location for worldwide Chrysler PT Cruiser production.
"Bringing a brand new vehicle, in an all new segment like the PT Cruiser to market
quickly - from concept to volume production -- is always an enormous task," said Gary
Henson, DaimlerChrysler Corporation Executive Vice-President of Manufacturing.
"Although the launch curve is ambitious, we're on schedule and we're shipping
product. We haven't lost any production, and we've stayed focused on quality throughout
the entire process. It's a success story for the PT launch team in Toluca and in Auburn
Hills."
Building on the design and development strength established during previous launches as
well as other best practices, the company has kept total Chrysler PT Cruiser startup costs
below $600 million, including design, development, re-tooling, training, facility
improvements, increased automation and pre-production trials.
"Bringing the PT Cruiser to market quickly, for relatively low cost is the result
of taking advantage of new technologies in development, implementing best practices
throughout launch, cutting waste out of the value chain, and using our Operating
Principles to efficiently produce repeatable, reliable world-class quality," said
Henson. "The goal is to get better with every launch, and we're doing that."
Flexible Manufacturing Launch
Currently the Chrysler Sebring Convertible, Chrysler Stratus and Chrysler PT Cruiser
are assembled in the plant on the same lines, demonstrating the manufacturing flexibility
of the Toluca facility. This level of complexity requires additional error proofing
measures throughout the manufacturing process.
Toluca has the capacity to produce 40 vehicles per hour. As it continues the aggressive
production launch, the number of PT Cruisers will steadily increase, as the number of the
Dodge Stratus and Chrysler Sebrings decrease. Likewise, the new 2001 Dodge Stratus and
Chrysler Sebring sedans, along with the Sebring Convertible will begin ramping up this
summer in Sterling Heights Assembly Plant (Michigan) while Stratus and Sebring coupes will
be produced in Normal, Illinois. This will bring Sterling Heights to full capacity, while
creating additional capacity in Toluca to support additional demand for the Chrysler PT
Cruiser.
At full production this summer, Toluca will have the capacity to produce about 180,000
Chrysler PT Cruisers annually. Approximately 3,400 team members operate on two shifts at
the Toluca plant.
Toluca will produce both right and left-hand drive 2.0 liter and 2.4 liter versions for
the world market. This is the first right-hand drive vehicle produced in the Toluca plant.
In order to reduce the complexity of adding a right-hand drive version, the vehicle was
designed to maximize side-to-side symmetry.
Additional right-hand drive assembly and testing capabilities were added throughout the
plant, including: on-line electrical system testers, radiator and hose installation
processes, chassis dynamometers, wheel alignment equipment, seat installation and tool
duplication for all operations that vary between the two configurations.
Training the Trainers
With the challenge of launching an all-new product with such innovative design and
complex engineering, team member training was extensive. Production teams from the plant
were integrated early in the design engineering verification process. The same teams were
trained with the first pilot vehicles developed at the DaimlerChrysler Tech Center (DCTC)
Pilot Plant in Auburn Hills, Michigan, in a "train the trainer" process. Core
production teams from Toluca, representing every workstation in the plant, rotated to
Auburn Hills in six week intervals, over eight months. These core teams then cascaded the
information back to the plant.
Ultimately one team member per workstation per shift was trained in Auburn Hills before
the start of the pre-production vehicle build, representing about 25 percent of the total
workforce at Toluca. Each trainer received nearly 500 hours of instruction, for a total of
120,000 hours, and was a crucial part of refining and evaluating production processes.
Following the pilot build in Auburn Hills, pre-production vehicles were built on the
assembly line in Toluca during normal production. This helped to refine production
processes on each station, and to ensure the repeatability and standardization necessary
for world-class quality. Running pre-production vehicles in the plant also saved both time
and money in product development.
Quality
Through continuous improvement processes, and its experience in using the company's
Operating Principles, the Toluca plant and its workforce have a reputation for producing
high quality vehicles at low cost. In fact, Toluca was one of many plants benchmarked by
the worldwide DaimlerChrysler manufacturing group in developing best practices for the
company's Operating Principles, the comprehensive system it uses to produce vehicles.
To ensure quality, the Toluca plant verifies parts, processes and fit and finish every
step of the way from stamping and body, to paint and final assembly.
Some of quality assurance processes include:
- Measuring dimensional accuracy of eight full bodies per day by determining
- millimeter variances in the x, y and z axis of 2000 points on the body using 5493
- charts;
- visual management through quality alert systems, which are designed to bring
- abnormal conditions to light immediately. The system provides visual and audible
- signals for each station for tooling, production, maintenance and material flow;
- the addition of 55 robots in the dimensional and integrity welding areas, including
- two framing stations;
- daily weld and sealing audits, performed by ultrasonic weld detection;
- daily body, paint and assembly audits for internal and exterior evaluation;
- 100 % Electrical and mechanical systems audits;
- 100 % water tests;
- daily customer satisfaction audit (CSA); and
- 100 % road test evaluation on the Toluca proving grounds.
The Operating Principles
Like all DaimlerChrysler Corporation's manufacturing facilities, Toluca conducts its
business using the Operating Principles. Rather than merely a way to assemble vehicles,
the Operating Principles represent the way the company does business and maintains a lean
extended enterprise system. It begins with core values and beliefs, the philosophical
principles from which decisions are made. From there, we look at the "how",
identifying the enablers and subsystems needed to execute our work (like human
infrastructure, balanced schedules, value added activities and robust processes). We then
identify ways to support those processes, tools for implementation, and standardized
measurements to gauge effectiveness.
The Operating Principles give employees at the plant the big picture framework from
which to operate, at the same time providing standardized methods and repeatable
processes. The end result can be tracked and improved by focusing on Safety, Quality,
Delivery, Cost and Morale (S,Q,D,C,M), internal gauges that each team member contributes
to. Because continuous improvement is one of the core beliefs, the process never stops.
Toluca has embraced the Operating Principles, evidenced in its well-organized
workstations, standardized processes, ability to use visual management, efficient material
handling, balance of high tech and manual processes and its commitment to training.
The Supply Chain
PT Cruiser suppliers were integrated in the cross functional teams early in the
development process. They participated in the pilot builds at DaimlerChrysler Technical
Center, as well as the pre-production vehicles in Toluca, to ensure the same high
standards are met throughout the supply chain.
The Toluca plant has many of its parts and modules delivered SPD (Sequential Parts
Delivery) and just-in-time to the plant. This allows the plant to maintain about a day and
a half of inventory, keeping the operation lean and efficient. Several suppliers located
operations near Toluca in order to better serve the plant. Depending on the type and
amount of components they supply, they either deliver to one of two nearby sequencing
centers or directly to the plant.
Stamping On Site
Toluca Assembly includes a satellite stamping plant on site to help reduce logistics
and production costs. With the Chrysler PT Cruiser, Toluca is also using DaimlerChrysler's
first compression seam (mash) welding. This enables team members to weld different
thickness of steel together and results in better structural rigidity with fewer parts,
which, in turn, leads to better dimensional integrity and quality.
