Quality Control at Plymouth Industries
At Plymouth Industries, quality is at the heart of everything we do. Our commitment to precision manufacturing and stringent quality control ensures that every component we produce meets the highest industry standards. With inspection technology and a dedicated team of experts, we guarantee exceptional accuracy and reliability in every product.
Quality Inspection Technologies
We invest in metrology and inspection equipment. Our tools provide highly accurate measurements and verification, ensuring that every part meets the required specifications.

Keyence Coordinate Measuring Machine (CMM)
The Keyence CMM delivers precise, automated 3D measurements with unmatched speed and accuracy.
- Non-contact, high-speed dimensional inspection
- Accurate 3D measurements of complex geometries
- Consistent quality verification for tight tolerances

FabriVISION Laser Projector Scanner
Our FabriVISION Laser Scanner enhances our inspection capabilities by providing:
- High-resolution scanning for rapid part verification
- Laser precision for complex shapes and profiles
- Efficient first-article inspections and in-process quality control
Comprehensive Inspection Process
To ensure consistent quality, we implement a multi-stage inspection process that verifies every part throughout production.
First Piece Inspection
Before production begins, a first-piece inspection is conducted to validate the setup and ensure that all dimensions meet specifications. This critical step prevents errors and ensures process accuracy before full production starts.
In-Process Inspections
Throughout production, our quality team performs in-process inspections at key checkpoints. This includes dimensional verification and visual checks to identify any deviations, ensuring that parts remain within tolerance throughout manufacturing.
Last Piece Inspection
Before completing a production run, a last-piece inspection is performed to confirm consistency from the first to the last part. This guarantees that the entire batch meets quality standards before final approval.
Final Inspection & Reporting
Every finished product undergoes a comprehensive final inspection, which may include:
- Full dimensional analysis using our Keyence CMM
- Surface and profile verification with the FabriVISION laser scanner
- Visual and functional testing as required
- Key customer interface feature verification
Upon request, we provide detailed inspection reports and certifications.


AWS Certified Welding & Inspection
We offer AWS Certified Weld Inspection upon request, providing expert verification and compliance documentation for welding projects that require precision and certification to industry standards. Whether you need weld inspection for compliance or quality assurance, our inspectors are available to meet your needs.
Production Part Approval Process (PPAP)
Upon request, we can furnish a Production Part Approval Process (PPAP) to validate our ability to produce consistent, high-quality parts. PPAP is an industry-standard procedure used across automotive, aerospace, government/defense, and other precision industries to ensure robust and repeatable manufacturing processes.
PPAP May Include:
- Dimensional Inspection Reports – Full verification of part dimensions using our advanced measurement equipment
- Material Certifications – Compliance with required material specifications
- Process Flow Diagrams – Detailed mapping of the production process
- Control Plans – Documented strategies for maintaining quality at every stage
- Failure Mode and Effects Analysis (FMEA) – Risk assessment to identify and mitigate potential manufacturing issues
- Initial Sample Inspection Reports (ISIR) – First-article approval to validate production readiness
Implementing PPAP provides confidence that all parts meet design and engineering requirements before full-scale production begins. This process minimizes defects, reduces production risks, and provides confidence in part quality and consistency.
