Pre-Production Inspection (PPI)

Pre-Production Inspection (PPI) is a quality control method conducted in the factory before the mass production begins. It will verify the status and quantity of raw material, assess the tools and production facility, and check the readiness of your supplier to proceed your order. It could be especially beneficial when working with a new supplier or starting a large contract with critical delivery date. Read more below.

Gain 24/7 Assurance With Our On-Site Guardians

Think of our pre-production inspectors as the guardians who hover over your factory day and night.

Like a protective bubble shielding manufacturing from defects, our inspectors spot risks in their infancy when they're still easily corrected. We'll walk the floor, confirming that equipment, raw materials, processes, and personnel all meet specifications down to the thousandth decimal.

When inevitable issues arise, we catch them quickly so that corrections happen before volume production begins. No more panicked reworking or shipping delays.

Complete Oversight

Our pre-production inspection services offer complete insight, including:

Raw Materials

We validate certificates to prevent sub-spec grades, examine composition for uniformity, and screen critical properties to ensure performance meets the required standards.

Parts and Components

We thoroughly vet suppliers, review certification specs, and test mission-critical functionality to avoid problems when production begins.


We assess equipment calibration, examine capability studies, validate maintenance, and check to ensure that the facility is suitable for achieving your level of process precision.

Quality Control

We review inspection protocols internally, ensuring that the correct procedures are all in place. Our checks will monitor the factory production sample to ensure it matches the client approved sample.

Gauges and Fixtures

We assess calibration seals, examine wear, measure against masters with known accuracy, and check suitability for your tolerance needs.

Facility and Organization

We evaluate the workspace, lighting, air quality, safety, maintenance, and tooling organization. We assess personnel qualifications to ensure they're appropriate. We also check storage and material handling.

Deliver Clarity on Risk Impacts

From multiple checkpoints, we spotlight the make-or-break ones for your situation. Using our decades of manufacturing expertise, we translate pre-production technical findings into plain insights.

We identify glitches that could impair functionality or affect per-unit costs. Our experts equip you to make knowledgeable choices on risk trade-offs, working solutions, or changing courses prior to mass production.

Rapid Remediation

Discoveries alone don't suffice. Through our local connections on-site, we can escalate issues directly to decision-makers who can then remedy them. Consider us your insurance to diagnose and resolve threats to your manufacturing process swiftly.

Comprehensive On-Site Assessments

When you engage us for pre-production inspections, our experts provide total visibility, from raw materials to final pre-production quality checks. We work across all of these areas:

Raw Material and Parts Status

We inspect raw materials and every component feeding the line to check that they are correct and meet the required specifications. We also assess protective handling and validation to ensure they match your grade.

Customer Special Checkpoints

We conduct rigorous testing of all customer requests, including components, facilities, and specific equipment. We also check that equipment and gauges are monitored for proper calibration, and that the facilities maintenance and capability ranges suit your tolerance needs.

Process Reviews

We thoroughly vet the methods to confirm they meet your most stringent product specifications and uphold blueprint requirements at each station.

Supply Chain Management

For multi-tier supply chains, we can trace components back to their originating sites and then down through intermediaries to identify vulnerabilities that can remain hidden if they are only assessed in the final assembly factory.

Production Readiness

We check the manufacturing facility to ensure that the layout is suitable to manufacture your order. We also examine equipment calibrations and procedures, testing environmental controls, technician competencies, and traceability practices.

Production Sample Validation

We examine production samples under diverse customer usage patterns across user environments and duty cycles.

Key Material and Package Verification

We check that cartons, pallets, inserts, and packaging components meet QC needs for being recyclable, water-resistant, and tamper-proof. We also check that they comply with destination requirements for barcodes and labeling.
