Technical Capabilities
Advanced Production Equipment
Equipped with 0+ advanced in-house production lines, including PVC/PET extrusion lines, twin-screw extruders, and heat-shrink sleeve printing units, ensuring superior product quality and manufacturing efficiency.
Extrusion production line
The company operates over 20 self-developed precision extrusion production lines for PVC/PET heat shrinkable sleeves, featuring mature sleeve molding processes. We support custom development for various sizes and specifications, reliably meeting high-volume, multi-product order requirements.
Printing Production Line
The company operates over 20 shrink sleeve printing lines, compatible with PET and PVC sleeves in various sizes. It supports multi-color and custom character printing to meet customers' personalized labeling needs.
Twin-screw extrusion granulation line
Equipped with high-capacity PET pelletizing lines, we produce core raw materials in-house. Our facility handles the full process of PET modification, compounding, extrusion, and pelletization, eliminating reliance on external suppliers. This enables strict control over raw material purity and performance metrics from the source. The high-capacity equipment aligns with our tubing production lines for scalable manufacturing, ensuring stable heat-shrink tubing performance and efficient delivery.
Complete Process Flow
From raw material inbound to finished goods outbound, our company implements a full-chain process and quality control system. Every production step strictly adheres to standards to ensure stable and reliable heat shrink tubing performance.
Incoming Material Inspection
Strictly vet suppliers and prioritize imported raw materials. Each batch undergoes performance and appearance testing using equipment such as melting point analyzers upon arrival; non-compliant materials are immediately rejected to ensure quality from the source.
Ingredient Mixing and Drying
Precisely meter and proportion raw materials for thorough mixing. Execute standardized drying processes to eliminate moisture risks, ensuring stable extrusion conditions downstream.
Extrusion molding
Form tubes via extrusion line with real-time monitoring of equipment temperature and production rate. Conduct in-process inspections for tube diameter, wall thickness, shrinkage rate, straightness, and appearance to optimize process parameters dynamically.
Semi-finished Goods and Printing Process Control
Blank sleeves undergo full-sample inspection and are accepted into inventory upon passing. Custom printing services are performed as needed, with strict control over specifications, print margins, and visual quality. Defective units are trimmed and scrapped.
Final Inspection and Packaging for Shipment
Perform final full-scope inspection on printed finished products, verifying specifications, performance, and appearance. Cross-check material batches and label markings. Only after passing inspection shall items be packaged according to standard procedures for warehouse release and delivery.
