From Drawing Confirmation to Mass Production: STRZ Quality Control Process
At STRZ, we understand that stable quality and accurate production are essential for long-term cooperation with our customers. Especially for customized metal products, every detail matters — from drawings and samples to mass production and shipment.
To ensure consistent quality, we follow a clear and practical quality control process throughout every order.
1. Drawing & Technical Confirmation
Before production, our team carefully checks all technical drawings, specifications, dimensions, materials, and surface treatment requirements with customers.
For customized hinges, stamping parts, ground screws, or wire products, we pay close attention to:
Hole positions
Thickness tolerance
Welding structure
Surface finish
Packing requirements
If necessary, updated drawings will be reconfirmed before production starts to avoid misunderstandings.
2. Sample Production Before Mass Production
For new items or customized products, sample production is arranged before bulk production.
This step helps customers verify:
Product dimensions
Assembly compatibility
Material quality
Surface treatment
Functional performance
Only after sample approval do we move forward with mass production.
3. Production Inspection During Manufacturing
During production, our team follows the confirmed drawings and samples strictly.
Random inspections are carried out during different production stages to check:
Dimensions
Welding quality
Surface treatment
Thread accuracy
Product consistency
For some orders, customers also require production photos or inspection reports before shipment.
4. Packing & Shipment Control
Before shipment, products and packaging are checked again to ensure:
Correct quantity
Proper labeling
Safe export packing
Clean appearance
Container loading safety
We understand that reliable packaging is also part of product quality.
At STRZ, we believe quality control is not only about inspection, but also about communication, responsibility, and execution.
We continue improving our production coordination and quality management to support customers with stable products and dependable service.
