What is During Production Inspection?

During Production Inspection (DUPRO) is a quality control process conducted while manufacturing is in progress.

The quality control team manually inspects products, measures deviations, prepares detailed reports, and ensures all products are perfect from both dimensional and qualitative aspects.

DUPRO inspections typically begin after 10-15% of production has been completed. This timing is optimal for identifying possible defects early enough to implement corrective actions before the entire batch is manufactured.

Key characteristics of DUPRO:

Real-time quality monitoring during manufacturing
Early defect identification and correction
Production progress verification
Compliance confirmation with specifications
Cost-effective problem resolution

Why Are During Production Inspections Necessary?

DUPRO inspections are crucial for business success and efficient production management. Here are the key benefits:

Quality Inventory Assurance

Quality is the cornerstone of business success. Inspections ensure quality in the most effective way, driving more sales and producing more satisfied customers with quality products delivered on time.

Timely Production Management

Want products delivered on schedule? DUPRO inspection is the best approach. During production monitoring provides clear visibility into:

Production speed and procedures
Expected completion timelines
Potential delays or bottlenecks
Factory compliance with schedules

Factories follow given timelines, and you receive the exact quantity of products as requested.

Factory Compliance Verification

Factories must follow all quality standards and specifications. Compliance is 100% crucial for:

Customer satisfaction
Brand reputation
Regulatory requirements
Long-term business success

Quality compliance impresses customers, increases sales, and enhances brand recognition.

Cost Savings

Identifying defects during production is significantly more cost-effective than discovering issues after production is complete. DUPRO helps you:

Avoid costly rework
Reduce waste and defective inventory
Prevent shipping delays
Minimize customer returns and complaints

How Does During Production Inspection Work?

The DUPRO inspection system follows a systematic, multi-stage process. At every step, our team thoroughly conducts the inspection and provides detailed reporting.

Step 1: Random Sample Selection

The inspection team selects random samples to test in the laboratory. We don’t rely on a single sample—we take multiple samples and test them all to check standards and determine average quality metrics.

Random sampling provides insights into:

Corrective actions needed
Product compliance levels
Representative quality across the entire batch
Statistical quality assessment

Step 2: Manufacturing Material Verification

The team verifies product quality based on raw materials and components. This is very crucial for ensuring:

Material authenticity
Specification compliance
Quality consistency
Cost-effectiveness without compromising standards

Step 3: Package Dimensions Inspection

Inspectors check packaging dimensions to ensure accuracy, including:

Accurate diameter and measurements
Protective material adequacy
Proper labeling and branding
Space optimization for shipping efficiency

Pro Tip: We identify opportunities for improvement, recommending accurate and concise packaging with appropriate protective materials.

Step 4: Detailed Reporting

Inspectors prepare comprehensive reports indicating:

Overall inspection results
Quality scores and ratings
Identified defects and issues
Corrective action recommendations
Production progress status
Compliance verification

FAQs About During Production Inspection

1. What is being checked in a visual inspection?

Visual inspection provides comprehensive insights into:

Product Visual Defects: Surface imperfections, color inconsistencies, finish quality
Material Quality: Visual material assessment and authenticity verification
Dimensions and Specifications: Visible measurements, proportions, and design accuracy
Workmanship: Manufacturing quality, assembly accuracy, overall appearance

Visual inspection plays a crucial role in identifying obvious quality issues quickly and cost-effectively.

2. What sampling method is used in DUPRO quality inspection?

ISO has standardized various sampling methods for inspections. At BSA GROUP, we primarily use:

ANSI/ASQC Z1.4 (ISO 2859-1) Sampling Method – The international standard for acceptance sampling
AQL (Acceptable Quality Limit) levels appropriate to your product type
Statistical sampling for representative batch assessment
Risk-based sampling for critical components

Our sampling methodology ensures statistically valid results while maintaining cost-effectiveness.

3. What is the role of quality control?

Quality control serves multiple essential functions:

Ensures Quality Products: Verifies products meet all specifications and standards
Prevents Defective Inventory: Identifies and removes defects before shipping
Boosts Sales: Quality products lead to customer satisfaction and repeat business
Protects Brand Reputation: Maintains consistent quality standards
Reduces Costs: Early defect identification minimizes expensive rework
Ensures Compliance: Verifies adherence to regulatory and industry standards
Improves Supplier Relationships: Clear quality feedback helps suppliers improve

4. When should DUPRO inspection be conducted?

DUPRO inspections should typically be conducted when:

10-15% of production is completed (early detection)
30-50% of production is completed (mid-production verification)
Before final packaging begins (last opportunity for corrections)
For large orders requiring multiple production runs
When working with new suppliers or products

5. How long does a DUPRO inspection take?

Inspection duration depends on:

Order quantity and complexity
Product type and specifications
Number of SKUs
Factory location and accessibility
Inspection scope and requirements

Typical inspections range from 4-8 hours for standard products, with detailed reports provided within 24-48 hours.
