Capability-Ruian Jinwangda Bags & Leather Goods Co., Ltd.

Craftmanship

Jinwangda runs a 10,000㎡ in-house facility equipped with advanced molding, thermoforming, sewing, and automated assembly technologies.
With a yearly capacity of 5 million hard-shell suitcases, we uphold a seamless process from material selection to final inspection, ensuring quality at every stage.

High standard production process

01
Material Sourcing

Based on custom requirements, we source ABS, ABS+PC film, PP, EVA shells, as well as linings, zippers, and wheel systems.

All materials undergo tests for colorfastness, impact resistance, abrasion, and extreme temperature durability to ensure stable quality.

Long-term partnerships with trusted suppliers guarantee consistency and timely delivery.
02
Sampling

From design drawings to physical samples, we provide a full sampling service.

After client approval, detailed process sheets and specifications are finalized for production.

New mold development (e.g., custom shell size or embossed logo) can be completed within 15–25 days.
03
Shell Forming & Structural Processing

Hard-shell cases are thermoformed (PC/ABS) with optional surface finishes: glossy, matte, frosted, or textured.

Logos can be applied via silkscreen, hot stamping, or embossing to enhance brand identity.
04
Assembly & Functional Testing

Core components—trolleys, wheels, locks, and frames—are assembled with high-precision equipment.

Premium zippers (e.g., YKK, SBS) undergo smoothness and anti-burst tests.

Every suitcase is tested for:

-Trolley extension and retraction

-360° wheel rotation

-Lock stability

-Load-bearing strength (≥50kg)

-Drop and impact resistance
05
Final Inspection & Shipment

Finished products undergo 100% inspection covering appearance, function, and cleanliness.

Defects are traced back to their source and corrected immediately to prevent batch issues.

Packaging features multi-layer shockproof and moisture-proof protection with customizable branding.

Orders are shipped on schedule with strict quality and safety assurance.

Strictly control every link to make every bag trustworthy.

Every piece of luggage we produce is the result of meticulous refinement and repeated testing. From material selection to assembly, testing to delivery, we adhere to stringent standards to ensure a flawless user experience for every customer.

Quality control process

Incoming Material

Environmental compliance (absence of harmful substances), plus initial checks for strength, waterproofing, and color consistency.

Incoming Material

In-Process

QC staff conduct random inspections at key stages such as cutting, assembly, and molding.

In-Process

Final Inspection

Full checks on appearance (no scratches, no color variance) and functionality (trolleys, zippers, wheels, locks). Products are cleaned, packed, and stored in the finished goods warehouse.
