Achieve optimal fill levels & minimise waste with our SPC solutions
Statistical Process Control and Process Capability are very much interrelated. A few decades ago, Quality and Technical Managers carried out Process Capability studies on their production lines, to determine where to set appropriate control limits. SPC would be an integrated part of such analyses.
Harford system automates SPC and Process capability analyses, establishing suitable Target and Control Limits for each product/production line to achieve optimal fill levels with minimal waste and fewer adjustments.
Improve production performance & optimise production outcomes
Harford Statistical Process Control (SPC), our advanced automated control system, ensures greatest stability, fewest number of adjustments, and optimal fill levels for each product/production line. By leveraging our cutting-edge SPC solution, manufacturers achieve enhanced process control, reduced variations, improved efficiency, and precise adherence to product specifications. Harford SPC helps manufacturers improve production performance and optimise production outcomes.
Process data, control charts & trend analysis tools
Harford SPC checks allow non-weight control tests to be performed on a whole range of products. Control can therefore be gained in such areas as:
- Temperature (°C, °F)
- Pressure (PSI)
- The torque needed to tighten caps on bottles (Nm, Ncm, n.lb)
- The length of particular product (cm, m, inches or feet)
They provide visual representations of process data, control charts, and trend analysis tools. Real-time alerts and notifications allow for proactive quality management, ensuring process stability and continuous improvement.
SPC solutions for FMCG, health & beauty, food & pharma companies
Many companies neither possess the knowledge, nor have the time to carry out such time-consuming studies. Consequently, it is now much more common to set arbitrary control limits for filling machines based upon ‘what Quality or Technical would like them to be, e.g. plus or minus 2 grams’.
This is why we developed the Harford system to carry out automatic SPC and Process capability analyses and to thereby set the most appropriate Target and Control Limits for each product/production line combination, to achieve optimum fill levels with minimal ‘giveaway’ and fewer process adjustments.

Who we have helped
What is SPC?
Statistical Process Control (SPC) is a methodology that uses statistical techniques to monitor and control manufacturing processes. It involves analysing process data in real-time to detect variations, identify root causes, and take corrective actions to maintain process stability and product quality.
What are the benefits of implementing SPC?
Implementing SPC offers several benefits. It helps to identify process variations, reduce defects, and improve overall product quality. SPC enables proactive monitoring and early detection of process deviations, preventing non-conforming products and minimizing waste. It also provides insights into process capability and helps in making data-driven decisions for process optimization.
How does SPC contribute to process improvement?
SPC contributes to process improvement by providing real-time data analysis and visualization. It helps identify common and special cause variations, allowing for targeted improvement actions. SPC facilitates continuous monitoring of process performance, enabling organizations to implement corrective measures promptly, reduce variability, and achieve consistent product quality.
What are the key elements of SPC?
The key elements of SPC include the identification of critical process parameters, data collection and analysis, control charting, setting control limits, and taking corrective actions based on statistical analysis. SPC emphasizes process stability, measurement system accuracy, and the reduction of common cause variation to ensure consistent and predictable process performance.
How can SPC improve overall productivity?
SPC improves overall productivity by reducing process variability and minimizing defects. By implementing SPC, organizations can identify and eliminate process inefficiencies, resulting in improved process yield, reduced rework or scrap, and increased throughput. SPC also enables process optimization, leading to enhanced resource utilization and operational efficiency.
