What You Need to Know About Quality Control

professionals at deskIn the manufacturing of rubber products, Quality Control (QC) is increasingly essential for producing high-quality parts. Rubber manufacturers utilize QC as a quality management system to ensure their products meet or exceed customer satisfaction first and cost-effectively improve production and efficiency continually. Where QC was once designed to focus almost entirely on customer expectations, which it still is, today QC procedures have evolved to include the entirety of manufacturing processes. This quality management approach provides a constant evaluation of those processes, which, in turn, ensures that the output of standard, specialty, or customized components and parts are of the highest quality.

Quality Control Program for Rubber Manufacturing

Implementing a QC program is more than merely signing a certificate for a finished part. A successful program opens up communication and creates an ongoing dialogue among management, engineering, quality personnel, and other employees to attain customer satisfaction. Well-informed personnel combined with well-defined controls can help standardize production and give personnel the tools to identify and react to quality issues in real-time. By limiting any chance of error, production efficiency, and products improve.

Before any product, part or component leaves the facility, QC is designed to test units to determine that they meet or are within final product specifications. The purpose of QC testing checks that quality standards are being met and identify if corrective actions need to be addressed in an area of the manufacturing process. An effective QC program helps rubber manufacturers produce conformity to quality standards. Once established, it gives manufacturers a benchmark to consistently meet those standards in the production of parts and components. QC is a system that selectively reviews, samples, identifies, and eliminates defective products during manufacturing. Effective quality control can locate and address defective products or the processes causing the problem, not only fix them but improve upon them before products enter the market and are purchased by consumers.

As QC has evolved, it has shifted from an entirely consumer-focused process to a more inclusive approach that reduces costs and increases efficiency as a whole. During manufacturing processes, an essential part of QC establishes protocols that anticipate mistakes. Continually testing and inspecting products for statistically significant variations in quality is how conformity in quality standards is established for products. It makes sure correct procedures are followed and, if a problem arises, it can be quickly identified as it happens.

At one-time quality, personnel was the only employees assigned specific QC functions, proper training of managers, and even regular line personnel ensure that manufacturing processes are executed correctly. Quality control is about certifying that goods will meet customer satisfaction and creating a manufacturing environment in which all parties—engineering, management, and personnel—strive for perfection.

Quality control inspecting and testing results are achieved through continuous statistical analysis of sample products and their processes. Data from sampling is collected and interpreted by inspectors to ensure conformity to quality standards and be quickly identified for quality issues. As a cost-saving measure, the amount of material wasted is reduced and, determining a defective product limits the potential of extended manufacturing downtime and decreased workflow. Any drop in profitability associated with time lost in production and labor is averted.

Finally, quality inspection also provides a tracking system and traceability of the product as it moves through the manufacturing process. Traceability records the information starting with the inventory of raw material when received through each step of manufacturing the process until products are shipped. Conformity of quality standards cannot be met without an inclusive quality management system to monitor product source, history, and distribution.

Once quality control systems were a primary way to ensure customer satisfaction, they are now part of a broader quality management system designed to reduce costs and improve efficiency. For rubber manufacturers, QC continues to ensure products meet or exceed customer expectations with effective integration within the entire manufacturing process.
