01 Company & Positioning
KSY Plastic Machinery specializes in the research and development of multi-layer co-extrusion blow molding technology. We design and manufacture high-precision, high-stability multi-layer barrier bottle production lines, with products exported to packaging producers in the cosmetics, food, pharmacy and industrial chemical sectors.
Product Line Coverage
Fully electric, hybrid and hydraulic blow molding machines. Suitable for 2–6 layer barrier containers, from small cosmetic vials to 5L industrial bottles.
Industry 4.0 Integration
Remote diagnosis and data collection modules are integrated on core components, giving customers a path toward a connected, smart factory.
20+ Years Engineering Expertise
Core technical and management personnel bring more than twenty years of machine-building experience to every project.
Full-Process Custom Engineering
From material compatibility to mould and automation integration, projects follow a complete process of consultation, design and installation support.
02 Multi-Layer Co-Extrusion Technology
High Barrier Performance
The EVOH layer achieves an oxygen transmission rate ≤0.5 cc/m²·day·atm, far below typical monolayer packaging — ideal for oxygen-sensitive formulations and foods.
Cost-Effective Resin Use
Expensive barrier material is used as a thin middle layer, keeping material cost reasonable while retaining excellent shelf-life protection.
Recycled Material Compatible
The middle layer can be formulated with post-industrial or post-consumer recycled material for a more sustainable package structure.

04 Key Technical Features
Intelligent Control System
B&R (Austria) or MOOG (Japan) high-precision wall thickness controller. Remote diagnostic and data logging support online process optimisation.
Precision Extrusion System
Modular screw design for different resin rheology. Quick colour change completed in 30–80 minutes.
Layer Thickness Control
EVOH barrier layer can be controlled to 5–10 μm, with melt pump flow fluctuation ≤0.5% for consistent wall distribution.
Advanced Clamping Structure
Opposite clamping design with multi-point mould centre adjustment for easier installation and maintenance.
Servo Energy-Saving Drive
Servo technology provides high speed and stable stops while lowering overall energy consumption compared to traditional hydraulic systems.
Broad Material & Design Support
Suitable for single-layer through six-layer cosmetics, medical and food containers. Recycling layer can be added for sustainable structures.
