VihoX-750 Fully Automatic Disposable Plastic Cup Production Line for PP, PET, PS & PLA Food Containers

Establishing a profitable disposable plastic cup manufacturing plant requires more than just an isolated forming machine. It demands an integrated, energy-efficient, and continuous production ecosystem. The VihoX-750 Fully Automatic Disposable Plastic Cup Production Line delivers a comprehensive turnkey solution—seamlessly engineering raw plastic resin feeding, high-precision sheet extrusion, high-speed multi-cavity thermoforming, automated robotic counting and stacking, inline bag packing, and zero-waste edge-trim granulating into a unified industrial workflow. Engineered specifically for high-volume manufacturers of disposable water cups, milk tea cups, yogurt pots, and deli containers, this turnkey line minimizes operational labor by up to 60% while maintaining strict wall-thickness uniformity and dimensional stability across 24/7 continuous cycles.

1. Engineering Principle & Multi-Stage Thermoforming Technology

The core of the VihoX-750 production line is built upon advanced positive-and-negative pressure pneumatic forming coupled with mechanical servo-plug assist. Unlike conventional single-station pressure formers that suffer from uneven material distribution in deep-draw designs, the VihoX-750 utilizes a four-column guided mold platen driven by high-torque eccentric cams and servo-assisted toggle linkages.

The production process operates in seamless synchronization:

• Continuous Roll/Inline Sheet Feeding: Extruded polymer sheet is precisely advanced into the pre-heating tunnel via bilateral needle-type servo chain rails with micro-adjustable width settings.
• Multi-Zone Infrared Ceramic Heating: Individual PID temperature modules control upper and lower ceramic heating arrays, ensuring that temperature-sensitive resins (such as polypropylene and PLA) achieve their optimal softening point (typically 155°C–168°C for PP) with less than ±1.5°C temperature variance across the sheet width.
• Synchronous Servo Plug-Assist Forming: As the sheet enters the 750 × 500 mm forming chamber, a servo-driven upper plug descends to pre-stretch the softened polymer down into the mold cavities. Concurrently, high-pressure compressed air (0.6–0.8 MPa) is injected from the top while vacuum suction (–0.08 to –0.09 MPa) is drawn through micro-vent holes at the cavity base.
• In-Mold Cutting & Trimming: High-precision alloy cutting dies shear the cup rims during the final fraction of the clamping stroke, guaranteeing burr-free, smooth lip curling edges that stack cleanly in downstream automated packaging systems.

2. Technical Superiority & Real-World Energy Efficiency

In industrial cup packaging manufacturing, profitability hinges directly on cycle speed, mechanical stability, and energy consumption per kilogram of finished goods. The VihoX-750 line is designed from the ground up to solve the core bottlenecks of traditional production plants:

• Substantial Energy Reduction: By optimizing ceramic heat reflector geometries and adopting high-efficiency IE4 servo drives with regenerative braking, the VihoX-750 consumes 15% to 18% less electricity than standard pneumatic-toggle forming systems under identical mold conditions.
• Ultra-Low Scrap Rate (<0.2%): Closed-loop servo tracking ensures repeatable feeding accuracy within ±0.15 mm, completely eliminating sheet slippage and reducing start-up scrap to less than 0.2%.
• High Clamping Rigidity: The machine frame is fabricated from stress-relieved, heavy-duty welded structural steel plate with a combined machine weight of approximately 6,500 to 7,200 kg. This robust mass dampens high-frequency mechanical vibration at speeds up to 30 cycles per minute, significantly prolonging mold cutting blade lifespans.
• Deep-Draw Versatility: With an effective forming depth adjustable from 180 mm up to 220 mm, the VihoX-750 effortlessly accommodates 32 oz giant beverage cups, deep food buckets, and square noodle bowls without requiring platen modifications.

4. Wide Polymer Compatibility: PP, PS, PET, PLA & Biodegradable Blends

The thermoforming market is undergoing rapid shifts driven by both material pricing fluctuations and regional single-use plastics legislation. The VihoX-750 line offers true multi-resin capability without mechanical retooling:

• Polypropylene (PP): The global benchmark for hot beverage and microwaveable food containers. Because PP possesses a narrow thermal processing window and high shrinkage rate, our precise multi-zone PID heating and high-pressure forming ensure exceptional bottom clarity and zero side-wall buckling.
• High Impact Polystyrene (HIPS & GPPS): Ideal for disposable cold drinking cups, dairy pots, and dessert bowls. The VihoX-750 provides rapid cycle times on polystyrene sheets with flawless rim curling definition.
• Polyethylene Terephthalate (A-PET / R-PET): Critical for crystal-clear cold drink cups, iced coffee cups, and fruit salad containers. When processing PET, our dedicated vacuum-cooling channels rapidly drop the formed cup below PET’s glass transition temperature (approx. 70°C) to prevent post-mold hazing.
• Polylactic Acid (PLA) & Bio-degradables: For brand owners targeting strict European and North American circular economy standards, the VihoX-750 handles certified compostable PLA and cornstarch-modified polymers with gentle thermal ramping to prevent molecular chain degradation.

5. Complete Turnkey Plant Integration: The 6-Stage Automated Flow

A truly modern manufacturing line eliminates manual handling between stages. The VihoX-750 turnkey configuration connects every piece of equipment into a balanced, continuous line:

1. Upstream Plastic Sheet Extrusion Line: A dedicated VihoX-110 or VihoX-120 Single-Screw PP/PS Extruder or 75 Co-rotating Twin-Screw PET Extrusion Line continuously delivers calibrated polymer rolls, equipped with automatic melt pumps and hydraulic screen changers.
2. High-Speed Thermoforming Host (VihoX-750): Forms, cuts, and trims the cups in-mold at continuous rates of 20,000 to 45,000 cups per hour (dependent on cup diameter and cavity count).
3. VihoX-CS750H High-Speed Cup Counter & Stacker: Formed cups are pushed into receiving guide tubes and transferred at up to 1,000 pcs/min, where optical counting sensors stack cups into pre-set batches (e.g., 50 or 100 cups per stack).
4. VihoX-CPM4 Automatic 4-Lane Cup Bagging & Packaging Machine: Counted stacks are pushed automatically into food-grade polyethylene film tubing, heat-sealed, and coded with batch dates, completely eliminating human contact and fulfilling international hygiene standards.
5. Inline Edge-Trim Granulating System (VihoX-800H Crusher): Skeletal waste sheet is immediately drawn into an inline low-noise acoustic crusher, ground into uniform regrind flakes, and pneumatically conveyed back to the extruder blending hopper for 100% closed-loop material recycling.
6. Supporting Utility Plant: Centralized chillers (VihoX-15AC / VihoX-20AC), round counterflow cooling towers (VihoX-80CT), and permanent-magnet VSD rotary screw compressors (VihoX-30PM / 50PM) provide uninterrupted cooling and dry pneumatic power.

7. Workshop Infrastructure, Electrical & Space Engineering

To ensure seamless machine commissioning and compliance with international ISO and CE factory safety requirements, plant owners must prepare the following site conditions:

• Total Factory Footprint: A full turnkey line (including extrusion, forming, automated packaging, and temporary finished carton storage) requires a recommended workshop area of 400 to 600 square meters with a minimum ceiling clearance height of 4.2 meters.
• Electric Power Supply: 3-Phase 380V/415V/480V, 50/60 Hz industrial grid. Total installed connected load for the complete line is approximately 320 kW to 360 kW, with an average operational consumption of approximately 180 kW to 210 kW under steady thermal equilibrium.
• Compressed Air Quality: Food-grade cup manufacturing strictly requires dry, oil-free compressed air. The compressor station must include a refrigerated air dryer and precision 3-stage particulate filtration down to 0.01 micron.
• Foundation Rigidity: Reinforced industrial concrete flooring of at least 250 mm thickness (C30 grade concrete) is required beneath the main forming press to absorb cyclic clamping shock loads.

8. Maintenance Schedules & Long-Term Operational Reliability

Downtime in a continuous packaging plant directly inflates unit production costs. The VihoX-750 line incorporates automated centralized lubrication and predictive sensors to maximize mean time between failures (MTBF):

• Automated Central Lubrication: A programmable grease injection pump delivers metered lubricant to all high-load toggle pins and linear guide bearings every 500 operating cycles.
• Cutter Blade Management: Cutting dies fabricated from premium SKD-11 or D2 high-alloy cold-work tool steel provide an expected working lifespan of 8 to 12 million cycles between regrinding intervals under proper clamping alignment.
• Infrared Heater Inspection: High-efficiency ceramic heating elements are monitored through current-sensing relays on the central touchscreen; burned-out elements trigger immediate visual fault locators on the HMI mimic screen.
• Daily Inspection Checklist: Operators must check pneumatic filter moisture traps, verify chiller water return temperatures (12°C–15°C), and ensure chain rail lubrication levels prior to commencing every production shift.
