JIT

  • Not working on anything that is not already sold

  • - 200 suppliers

  • - Only maintain 48 hours of inventory

  • - Quality control takes place on the assembly line

  • Everything is team oriented, no employee spends longer than 2 hours at a single project

  • - Utilize Kanban cards


Suppliers l.jpg
Suppliers

  • Hire Diversified suppliers ( woman owned)

  • Must meet quality standards to

  • Minimal inspection of received materials

  • Maintain long-term contracts with suppliers

-Toyota Tacoma ( Compact pickup truck standard, extra and double cab)

- Toyota Voltz ( Exported to Japan)


Production l.jpg
Production

NUMMI cars and trucks begin as giant rolls of coiled steel, 97% of which come from the Midwest. These coils weigh as much as 48,000 pounds each. Every day NUMMI uses nearly a million pounds of steel to manufacture its vehicles.

Sheets of metal pass through stamping presses that can weigh up to 57,000 pounds each. These use different dies and molds to stamp, or form, three-dimensional parts.

In order to understand the vehicle manufacturing process at NUMMI, we will follow a well recognized part - a door - through the various departments

This door started as a flat piece of metal, and through a series of three or four pressings we end up with the finished product. Now it’s off to Body and Weld…


Production body and weld l.jpg
Production- Body and Weld

We have two large robot welding lines that use about 100 robots to weld outer bodies together.

Here’s the door again. We have more than 1,000 multi-welders throughout NUMMI. These are smaller welding machines. Team members put the metal parts into place, hit a switch, and the machine does the welding. Less than 10 percent of welding is done manually.

Once completed, the door is attached to the vehicle, goes through a thorough inspection, and then it’s on to Paint.


Production paint l.jpg
Production -Paint

Inspection is the key in the Paint department. Vehicles are repeatedly checked during all five phases:

  • Phosphate bath ­ anticorrosion treatment/scoring of the body and a positive-charged immersion bath that help the metal body and paint to bond

  • Sealer/anti-chip ­ soundproofing, waterproofing and an application in wheel wells to prevent chipping from rocks

  • Primer ­ first spray stage

  • Top coat/clear coat – color and top coat spray

  • Assembly scheduling – vehicle bodies travel to the main plant, where finishing touches are applied and they await delivery to the assembly line.


  • Production plastics l.jpg
    Production- Plastics

    Plastics supplies the assembly lines with bumpers, instrument panels and numerous small parts. Small plastic pellets are melted then inserted into molds in a process called injection molding. Using cooling lines, the plastic solidifies to make the finished product.

    Here, the mold is separated, and the instrument panel is gently removed (it’s easily scratched at this time) and sent to Paint.

    We also produce bumpers for our cars.


    Production assembly l.jpg
    Production- Assembly

    After Paint, the first step in Assembly is to detach the doors, making it easier for team members to work on the vehicle as it travels down the line. The door is finished in another area of the plant. Toward the end of the line, our door meets up with the body and is reattached.

    Other steps in the Assembly process include installation of parts such as…enginestires


    Production quality control l.jpg
    Production- Quality Control

    Quality isn’t something we only check for at the end of the process; it is built into NUMMI cars and trucks at each stage. Our Quality Control and Quality Assurance departments conduct inspections, tests and audits to ensure customer satisfaction. They also work with all areas of the plant to address and prevent problems and to increase awareness of the importance of maintaining quality in each work station. The end result is a quality vehicle that finds its way to a General Motors or Toyota dealer and, eventually, the customer.
