Case Study: Implementing SPC in an Automotive Parts Manufacturing Company

Company Background:
AutoParts Inc. is a leading manufacturer of precision automotive components, supplying parts to major automobile manufacturers worldwide. The company prides itself on delivering high-quality products and maintaining stringent quality standards.

Challenge:
AutoParts Inc. was experiencing a high rate of defects in its brake pad production line, leading to increased rework costs, delayed shipments, and customer dissatisfaction. The primary issue was variability in the thickness of the brake pads, which needed to meet precise specifications to ensure safety and performance.

Objective:
Implement SPC techniques to monitor and control the production process, reduce variability, and improve product quality.

Steps Taken:

  1. Identify Critical Quality Characteristics:
  • The critical quality characteristic identified was the thickness of the brake pads, which needed to be within a specified tolerance range.
  1. Define Quality Standards:
  • The required thickness of the brake pads was set at 10 mm ± 0.2 mm. The company aimed to achieve this specification consistently to reduce defects.
  1. Select Appropriate Tools:
  • Control charts were chosen as the primary SPC tool to monitor the thickness of the brake pads. Specifically, X-bar and R charts were selected to track the mean and range of the thickness measurements.
  1. Data Collection:
  • A sample of brake pads was measured at regular intervals during production. Each sample consisted of 5 brake pads, and the thickness of each pad was recorded.
  1. Establish Control Limits:
  • Using historical data, control limits were established for the X-bar and R charts. The control limits were set at ±3 standard deviations from the mean thickness.
  1. Develop Control Charts:
  • X-bar and R charts were plotted to monitor the process over time. The charts displayed the mean thickness and the range of the sample measurements, with control limits clearly marked.
  1. Monitor Process Performance:
  • The production process was continuously monitored using the control charts. Operators were trained to interpret the charts and identify any points or patterns indicating out-of-control conditions.
  1. Investigate and Correct Issues:
  • Whenever a point fell outside the control limits or exhibited a non-random pattern, the production line was stopped, and a root cause analysis was conducted. Common causes of variation included worn-out machining tools, improper calibration of equipment, and inconsistent raw materials.
  • Corrective actions were implemented to address these issues, such as replacing worn tools, recalibrating machines, and working with suppliers to ensure consistent raw material quality.
  1. Implement Continuous Improvement:
  • Insights gained from the SPC implementation were used to drive continuous improvement initiatives. This included regular maintenance schedules for equipment, ongoing training for operators, and enhanced quality control measures for incoming materials.

Results:

  • The implementation of SPC resulted in a significant reduction in the variability of brake pad thickness. The proportion of brake pads meeting the specified tolerance increased from 85% to 98%.
  • Defect rates were reduced by 70%, leading to lower rework costs and improved production efficiency.
  • Customer satisfaction improved, with a notable decrease in complaints related to brake pad quality.
