Technical Services & Support for Plastic Packaging Machinery
JIUYI Machine provides full-lifecycle technical services, backing international customers from initial production requirements and machine selection to customized configuration, pre-shipment testing, global deployment, and after-sales support. Certified to ISO and CE manufacturing standards, our engineering team brings decades of experience in packaging automation projects.
Our service portfolio covers film blowing machines, printing presses, bag making machines, plastic recycling systems, slitting and rewinding equipment, paper packaging machinery, and complete auxiliary production lines. Whether you are expanding an existing plant, upgrading a legacy line, or setting up a new manufacturing facility, our technical team evaluates your output targets and builds a turnkey equipment configuration.
Our End-to-End Service Process
Requirement Analysis: We review your final product specs, raw material grades, target dimensions, output capacity, printing requirements, and local operating conditions.
Machine Selection: Our engineers match your application profile to the optimal machinery class, base configuration, and auxiliary options.
Production Line Design: For integrated operations, we map out a synchronized workflow-such as film extrusion feeding directly into multi-color printing and bag making-to eliminate workflow bottlenecks.
Machine Customization: Specifications are engineered to your exact product dimensions, material behaviors, target speeds, and regional electrical standards.
Manufacturing & Testing: Equipment is assembled in-house and subjected to strict mechanical, electrical, and live running tests prior to shipment.
Delivery & Installation Support: We supply comprehensive documentation and step-by-step guidance to ensure smooth mechanical positioning and commissioning.
Operator Training: Your staff receives hands-on training covering machine startup, parameter tweaking, routine maintenance, safety protocols, and basic troubleshooting.
After-Sales Support: Our technical desk remains accessible for 7x24 remote troubleshooting, maintenance consulting, and fast-track spare parts identification.
Precision Machine Selection
Different flexible packaging items require distinct equipment configurations. A line built for thin, high-clarity LDPE film will struggle with heavy-duty agricultural sheets, just as standard bag makers cannot sustain high-volume automated courier bag production.
We evaluate seven core variables before recommending any model:
Final Product: Shopping bags, garbage bags, zipper pouches, courier bags, agricultural greenhouse film, shrink wrap, and other flexible plastic products.
Raw Material: HDPE, LDPE, LLDPE, PP, PLA, and post-consumer recycled (PCR) plastic blends that dictate extrusion temperatures and screw designs.
Product Dimensions: Film widths, lay-flat dimensions, bag lengths, gusset depths, and micron thickness tolerances.
Production Capacity: Target output volume per hour or shift, driving machine sizing, motor power, and automation tiers.
Printing Requirements: Number of colors, printing width, surface corona treatment, and tight-tolerance color registration.
Automation Requirements: Level of inline automation, automatic tension control, web guiding, and auto-stacking capabilities.
Electrical & Factory Conditions: Regional voltage and frequency variants (e.g., 380V/50Hz, 415V/50Hz, 480V/60Hz), factory footprint limitations, and compressed air availability.
Production Line Design & Workflow Integration
Purchasing isolated machines from different vendors frequently leads to material incompatibility, speed mismatches, and communication gaps. JIUYI engineers complete end-to-end production layouts to guarantee synchronized throughput:
Plastic Film Production
Raw Material -> Film Blowing -> Film Cooling & Stabilization -> Edge Trimming -> Film Winding -> Finished Film Roll
Printed Plastic Bag Production
Raw Material -> Film Blowing -> Corona Treatment -> Flexographic/Gravure Printing -> Bag Making & Sealing -> Inline Punching -> Counting & Packing
Recycled Plastic Production
Plastic Waste -> Crushing -> Friction Washing -> Hot/Cold Rinsing -> Drying -> Extrusion & Devolatilization -> Strand Pelletizing -> Uniform Recycled Pellets
Integrated Packaging Production
Film Extrusion -> Printing -> Bag Conversion -> Automated Quality Inspection -> Final Bundling & Packing
Custom Machine Engineering
While standard configurations suit most applications, custom projects demand specialized dimensions, reinforced structures, or tailored control logic. JIUYI handles non-standard engineering requests based on verified technical feasibility:
Machine & Die Width
Configured precisely to match required film lay-flat dimensions or jumbo bag widths.
01
Extrusion & Screw Geometry
Customized L/D ratios and screw flights optimized for specific bio-plastics or recycled polymer percentages.
02
Cutting & Sealing Systems
Specialized thermal knives, cold-cut attachments, bottom-seal, side-seal, or header-seal configurations.
03
Automation Tier
Upgrades from manual collection to fully automated robotic stackers and automatic roll changers.
04
Electrical Compliance
Built to international compliance directives, featuring CE-certified components, robust safety interlocks, and multi-voltage transformers.
05
An industrial machine is a long-term production asset. Every JIUYI machine undergoes a multi-stage factory acceptance test (FAT) protocol before it leaves our floor:
Assembly Inspection: Systematic checks of mechanical frames, gearboxes, transmission systems, and pneumatic plumbing.
Electrical Inspection: Verification of wiring harnesses, PLC logic boards, solid-state relays, temperature controllers, and emergency safety stops.
Mechanical Adjustment
Calibration of nip rolls, guide rollers, tension arms, and cutting blade alignment.
Running & Production Tests
Live dry-runs and simulated material stress tests to verify stable motor speeds, smooth thermal profiles, and zero abnormal vibration.
Export-Grade Packaging
Sealed in moisture-resistant vapor barrier film, secured within fumigation-free wooden crates, and braced to withstand multi-modal international freight.
Installation, Commissioning & Operator Training
Deploying complex imported machinery requires a structured commissioning approach to protect your capital investment:
Comprehensive Documentation
Every shipment includes detailed operation manuals, electrical schematics, PLC wiring diagrams, pneumatic layouts, and preventive maintenance logs.
Installation Guidance
Our engineering desk provides remote, visual, and written milestone instructions to guide your local mechanical and electrical technicians.
On-Site Engineering
For complex multi-line installations, veteran JIUYI commissioning engineers can be deployed directly to your factory floor (arranged via formal service agreement).
Hands-On Operator Training
We train your supervisors and technicians on safe startup procedures, HMI touchscreen navigation, temperature-speed balancing, rapid size changeovers, and day-one troubleshooting.
Technical Support & Spare Parts Lifecycle
Post-sale responsiveness determines whether minor adjustments cause hours of downtime or just minutes of interruption. JIUYI offers robust, long-term operational backing:
Remote Troubleshooting: Share error codes, parameters, photos, or video clips via secure communication channels for rapid diagnosis by our senior technicians.
Fast-Track Spare Parts Supply: We maintain a deep inventory of wear parts and replacement components ready for immediate international dispatch via DHL, FedEx, or air cargo.
Supported Component Categories:
Precision mechanical gears, shafts, and bearings
Electrical PLCs, inverters, sensors, and contactors
Ceramic and cast-aluminum heating bands
Pneumatic cylinders, valves, and air regulators
Tungsten steel cutting knives and sealing wires
