Plastic Injection Molding Quality Control

The First Time, On Time, Every Time!

As an ISO 13485 injection molding partner, quality is the driving force behind everything we do at Westec Plastics. Our plastic injection molding quality control processes begin at the earliest stages of a project and continue through production, inspection, packaging, and final delivery.

With over 50 years of experience, we support industries that require precision, consistency, and compliance,  including medical devices, biotech, pharmaceutical, electronics, aerospace and defense, industrial, and consumer applications.

Integrated Quality Systems & Inspection Capabilities

Our quality department plays a critical role in maintaining consistent, repeatable results across every program. We utilize advanced inspection and data analysis tools, including:

• Keyence IM-7030T Instant Measurement System
• Micro-Vu Excel 652UC CMM
• QC-Calc SPC software for real time data collection and analysis

These systems allow us to support tight tolerances, validate performance, and maintain full visibility into part quality throughout production.

Quality Control Throughout Production

Quality is built into every stage of the manufacturing process — not just at final inspection.

• Operators and production teams are trained to monitor cosmetic and visual criteria
• In process inspections are conducted at defined intervals
• Critical dimensions are measured and tracked to ensure consistency
• SPC methodologies are used to monitor trends and maintain process control

This approach ensures every part meets specification and performs as expected across production runs.

Validation, Documentation & Compliance Support

To support regulated industries and customer requirements, Westec provides comprehensive quality documentation and validation services, including:

• First Article Inspection (FAI)
• Process validation support
• Customized inspection reports
• Gage R&R studies
• Certificate of Compliance (CoC)
• Raw material certifications
• RoHS and REACH compliance documentation

Our ISO 13485 injection molding certification ensures we meet the quality and documentation standards required for medical and other regulated applications.

Supporting Confidence Through Consistent Quality

Westec Plastics works closely with customers to ensure quality expectations are clearly defined and consistently met. Our team is trained, experienced, and committed to maintaining high standards across every program.

This combination of plastic injection molding quality control, advanced inspection capabilities, and responsive support helps customers reduce risk and maintain confidence in their production.
