Background

 Management at AcceStyle has expressed deep
  dissatisfaction with scrap produced in manufacturing.
 Thermoforming is a manufacturing process for
  relatively small batches of acrylic plastic product.
 Prices of raw acrylic plastic have also increased
  recently.
 Current state of the process has not changed in many
  years
 Savings through scrap reduction have become a
  priority.

Potential BI Enhancements

 BI + LLS = Powerful Toolset.
 BI supports decision making and process
  improvement.
   Process analysis - better identification and
    representation of the problem data.
   Project selection - demonstrate justifiable investment of
    resources.
 Defining the “baseline” through a BI “dashboard”
  provides for easy evaluation in the later steps of LSS

 Used to substantiate existence of an internal change in
  the process
   Tested that there is no change to the process inputs
   Tested that there is a significant change to the process
    output (scrap rate)
 Tested mean and variance of inputs and output.
    Inputs characteristics exhibited a constant mean and
     variance over the period of available data.
    Mean scrap production increased (p-value approx 0.000)
    Scrap production variance increased (p-value approx
     0.000)

Pilot Program
Goal: Show scrap can be reduced to acceptable limits

  Test changes for one Thermoforming station for one
   week. Share equipment with Eng. Dep. during trial.
  Train fork truck drivers to decrease damage to tools
   along with adding lighting and padding on the tool
   racks

  Pilot program produced scrap at 2.45%, compared to a
   calculated 3.6% without changes!
  All drivers showed increases in precision and accuracy!

Mistake Proofing

Mistake: Forming New Covers After Every Run Increases Scrap


Proofing:
Form one cover that is tagged upon release to production and stays
with tool between runs

SOP Change:
1. Operator signs-off for tool condition and raw materials at start
   of run
2. Cover is Stored at Machine While Tool Runs
3. Forklift driver signs-off on tool condition and formed parts at
   end of run

Ensure existing tool cover is not scrapped by operator

Solution:
Operator and forklift driver must sign for tool condition, formed
parts and any scrap.

Change Management
• The following actions are required to ensure process
  change is maintained and to be continued till the new
  process become a routine.
   • Supervisor has to visit the manufacturing floor more
     frequently ensuring:
       • Operators pay attention to the temperature of the
         mold at the start of the run.
       • Operators inspect the raw materials prior to run.
       • Operators store cover at machine while tool runs
       • Operators inspect the tool condition
       • Forklift drivers inspect the tool condition
       • Forklift drivers inspect the formed parts at the end
         of the run
