In B2B industrial operations, packaging is not just a commodity but an integrated part of the supply chain logistics. A minor structural defect or delivery delay can stall a massive assembly line. Recognizing this importance, Chau Thai Son Printing and Packaging Joint Stock Company has standardized an 8-step closed-loop production process, guaranteeing consistent quality, shipping safety, and a 15% - 20% reduction in packaging costs for our partners.
Step 1: Customer Needs Survey and Analysis
Chau Thai Son's consulting team works directly with clients to identify exact technical requirements: product physical characteristics, shipping methods (domestic transport or air/ocean export), and warehousing stack heights to define required bursting strength and Edge Crush Test (ECT) ratings.
Step 2: 3D Structural Design Consulting
Based on the survey results, Chau Thai Son's structural engineers design the packaging layout in 3D. We analyze flute structures (A, B, C, E flutes) and paperboard weights to maximize vertical load limits of the corrugated boxes while minimizing overall paper consumption.
Step 3: Complimentary Physical Mockups (Prototypes)
This is a premium privilege at Chau Thai Son. Prior to mass production, 3D design drawings are sent to digital sample table cutters to create physical Mockups that are 100% identical to the drawings. Clients receive these samples free of charge to test product fit and stack capabilities.
Step 4: Quality Material Sourcing and Inspection
Upon prototype approval, we source paperboard reels from leading global suppliers such as Oji, Vina Kraft, and Hansol. Raw paperboard undergoes moisture testing using infrared sensors (restricted to 6% - 8%) to ensure optimal corrugation bonding.
Step 5: Sheet Corrugating on High-Speed BHS & Hsieh Hsu Lines
Raw paperboards enter our combined Hsieh Hsu (Taiwan) and BHS (Germany) corrugator lines operating at speeds up to 400m/min. Automated steam heating and starch adhesive application produce flat, rigid 3-ply, 5-ply, and 7-ply cardboard blanks without blistering.
Step 6: Offset Roland R706 Printing and Finishing
Cardboard blanks are processed through the German Roland R706 6-color Offset printing press, producing vibrant prints accurate to the millimeter. Sheets then pass through the GSZ-1020 system for film lamination or spot UV coating to resist moisture and enhance aesthetics.
Step 7: Flatbed Die-Cutting on a System of 6 Automatic Presses
Printed and laminated sheets pass through our system of 6 automatic and semi-automatic die-cutters. CNC-milled steel rule dies crease and cut folding flaps down to the millimeter, ensuring boxes assemble square on automated packing lines.
Step 8: Just-In-Time (JIT) On-Site Logistics
Operating a 30,000m² factory in Que Vo Industrial Park and a dedicated fleet of trucks, Chau Thai Son manages direct logistics to clients' warehouses. We synchronize deliveries according to the Just-In-Time (JIT) model, delivering batches in lockstep with client assembly line demands to minimize customer storage requirements.
