VihoX-750 Fully Automatic Disposable Plastic Cup Making Machine: High-Speed Production Line for PP Drinking Cups

For packaging manufacturers and beverage bottling plants, investing in a disposable cup making machine comes down to three operational variables: real-world cycle stability, material yield per kilogram of sheet, and end-of-line labor costs. While nominal speed on a brochure can look impressive, true manufacturing profitability is engineered in the mold platen, the thermal consistency of the oven, and how efficiently finished cups transition from trimming to boxing.

The VihoX-750 cup thermoforming machine represents the industry sweet spot for medium-to-large scale cup production. With an effective forming area of 750 × 480 mm and a maximum forming depth of 220 mm, this continuous thermoformer bridges high-output speed with low utility consumption. Below is an engineering walkthrough of the live production run, detailing cavity layout economics, mechanical kinematics, and the fully automated 6-lane stacking system.

Production Stages & Multimodal Transcript

• 00:00 – 00:08 | Continuous Sheet Feeding & Heating: High-clarity PP roll stock is fed via precision bilateral clamping chains through the enclosed dual-heating infrared oven.
• 00:09 – 00:17 | In-Mold Forming and Blanking: The synchronized mechanical platen drives the male plug assist and pneumatic pressure forming, simultaneously completing clean rim punching in a single stroke.
• 00:18 – 00:26 | Continuous Skeletal Web Extraction: The perforated skeletal plastic web is smoothly pulled upward and rewound overhead, preventing jam risks and preparing clean scrap for immediate granulation.
• 00:27 – 00:35 | Automated 6-Lane Cup Stacking & Conveyance: Formed cups are pneumatically pushed into 6 parallel stainless steel guide tracks, automatically counted, nested into tight, uniform stacks, and moved forward for boxing.

Why the 750 × 480 mm Forming Footprint Dominates Water Cup Manufacturing

When planning a disposable cup plant, selecting the platen dimension dictates your factory’s production ceiling and tooling versatility. The 750 × 480 mm forming window on the VihoX-750 has become the international benchmark for standard disposable tableware.

Cavity Layout Math: Why 20 to 24 Cavities Deliver Ideal Yield

For standard 200 ml to 350 ml (7 oz to 12 oz) disposable drinking cups, the top rim outer diameter typically measures between 70 mm and 75 mm. Within a 750 mm width and 480 mm advance length:

• Layout Geometry: Molds are arranged in staggered or matrix layouts (e.g., 4 rows × 5 columns = 20 cavities, or 4 rows × 6 columns = 24 cavities).
• Web Efficiency: The skeletal web gap between adjacent cavity cutter rings is maintained at a compact 2.5 mm to 3.5 mm, minimizing raw material scrap to the lowest practical threshold.
• Tonnage Distribution: At 24 cavities, the required cutting force is balanced evenly across the heavy-duty four-column guided platen, preventing localized blade wear and uneven rim curling.

Theoretical Speed vs. Real-World Output per Hour

While brochure ratings frequently cite maximum mechanical speeds of up to 30 cycles per minute, a prudent factory manager calculates output based on thermal cooling windows:

• Heavy-Gauge Cups (Smooth/Rigid Commercial PP): Running at a reliable 20 to 24 cycles per minute with a 24-cavity mold yields 28,800 to 34,560 finished cups per hour.
• Ultra-Lightweight Cups (Vending/Water Cups): With optimized chilled water cooling (8°C to 12°C mold core circulation), cycles can reach 26 to 28 cycles per minute, surpassing 38,000 cups per hour.
• Shift Calculation (10-Hour Shift at 90% OEE): Delivers between 250,000 and 320,000 packaged cups per shift with minimal operator intervention.

Core Engineering Breakdown: From Sheet Feeding to Precision In-Mold Blanking

The VihoX-750 relies on a synchronized mechanical cam and hydraulic actuation architecture designed for 24/7 continuous industrial duty.

1. Servo Pre-Feeding and Clamping Chain Tension

Polypropylene sheet undergoes thermal expansion when heated. To prevent lateral sagging and uneven pitch advance:

• High-torque servo motors drive the feed rollers with an incremental positioning accuracy of ±0.15 mm.
• Bilateral bidirectional water-cooled chain rails grip the sheet edges, ensuring that thermal softening does not distort feeding registration.

2. Multi-Zone PID Infrared Heating for PP Temperature Uniformity

PP possesses a narrow thermoforming processing window (typically between 155°C and 165°C). Uneven heating results in either cold spots (causing premature stress whitening and thin cup bottoms) or overheating (causing sheet dripping).

• The VihoX-750 incorporates an extended upper and lower ceramic infrared heater bank divided into multiple independent PID temperature zones.
• Individual row tuning allows operators to compensate for edge heat dissipation, delivering a uniform sheet temperature gradient across the entire 760 mm maximum roll width.

3. Mechanical Cam Drive with Pneumatic/Vacuum Assist Forming

Deep-draw containers require controlled wall thickness distribution:

• Motorized upper plug assists (syntactic foam or POM plugs) descend mechanically to pre-stretch the plastic sheet into the cavity.
• High-pressure compressed air (0.6 to 0.8 MPa) is injected instantaneously, locking the molten polymer against the precision-machined, mirror-polished aluminum mold walls.

4. Integrated Precision In-Mold Punching (Burr-Free Rims)

Unlike older two-station lines that require separate trim presses, the VihoX-750 employs in-mold punching:

• Forming, lip curling, and perimeter cutting happen simultaneously inside the mold platen.
• This eliminates registration errors caused by thermal shrinkage between forming and trimming stations, guaranteeing that every cup rim is 100% round, smooth, and burr-free.

The Labor-Saving Advantage: Automated 6-Lane Cup Counting and Stacking Conveyor

As visible in the live production footage, the standout automation upgrade on the VihoX-750 is the forward-mounted 6-channel cup nesting and stacking conveyor.

In traditional factory setups, 2 to 3 workers must stand at the machine ejection port to manually gather, count, and align loose cups into stacks. This traditional method creates three major operational liabilities:

1. High Ongoing Labor Overhead: 2 to 3 workers per shift across multiple machines quickly erodes operating margins.

2. Food-Grade Sanitation Violations: Direct hand contact with cup interiors risks contamination under modern ISO 22000 and HACCP food-contact regulations.

3. Packaging Bottlenecks: If a manual packer slows down, the entire thermoforming line must be paused or cups spill onto the floor.

How the VihoX Automated Stacking System Operates:

• Pneumatic Push-Out: Immediately following in-mold cutting, a synchronized pneumatic ejector plate pushes the freshly formed rows of cups forward into aligned receiving guides.
• Continuous Guided Nesting: Cups slide into 6 parallel stainless steel guide lanes with low-friction polymer guide rods. Each cup smoothly inserts into the preceding one.
• Optical Batch Counting: High-speed photoelectric sensors count each passing cup. Once a pre-set quantity (e.g., 50 or 100 cups per sleeve) is reached, the conveyor advances the completed stack forward.
• Seamless Packaging Hand-off: The consolidated stacks travel directly to the downstream automatic bagging or carton packing machine, reducing the entire production line’s staffing requirement to just one line supervisor.

Material Versatility: Why PP Remains the King of Disposable Beverage Cups

While the VihoX-750 handles a broad spectrum of thermoplastic polymers—including PS, HIPS, PET, PVC, and bio-based PLA—polypropylene (PP) accounts for over 75% of global disposable cup manufacturing.

With quick mold and heater profile changeovers, the VihoX-750 allows producers to switch between economical PP water cups and crystal-clear PET iced beverage tumblers within 2 to 3 hours.

Frequently Asked Questions (Buyer Decision Guide)

1. How many finished cups can the VihoX-750 produce in an 8-hour shift?

Assuming a 20-cavity mold for standard 200 ml PP drinking cups running at a conservative 22 cycles per minute, the machine produces approximately 26,400 cups per hour. Over an 8-hour production shift at 90% Overall Equipment Effectiveness (OEE), output typically exceeds 190,000 finished cups. With a 24-cavity tooling setup, shift output surpasses 220,000 cups.

2. Can the VihoX-750 machine produce different cup sizes on the same line?

Yes. The VihoX-750 is built for rapid tooling changeovers. By switching the aluminum forming mold, cutting rings, and plug assist heads, you can manufacture 100 ml portion cups, 200 ml drinking cups, 500 ml milk tea cups, or even shallow round food bowls. Complete mold changeover typically takes 2 to 3 hours with experienced technicians.

3. What is the advantage of in-mold cutting over a separate trim station?

In-mold cutting punches the cup rim while the plastic sheet is still clamped in the mold platen. Because polypropylene shrinks unpredictably as it cools, separating forming and trimming into two stations often causes rim misalignment, oval cup mouths, and jagged burrs. In-mold cutting guarantees absolute concentricity, razor-sharp edges, and perfect stackability.

4. How much labor does the automated 6-lane conveyor save?

A conventional cup thermoformer requires 2 to 3 operators per shift dedicated solely to collecting, manually counting, and boxing loose cups. The VihoX automated 6-lane conveyor automatically stacks and pre-counts the cups into uniform columns, allowing a single operator to oversee multiple packaging lines, cutting line labor costs by 60% or more.

5. What thickness of PP sheet is recommended for disposable water cups?

Standard commercial 200 ml to 250 ml disposable water cups generally utilize PP sheet between 0.60 mm and 0.85 mm in thickness, resulting in finished cup weights between 2.2 g and 3.5 g. For heavy-duty beverage tumblers, sheet thicknesses of 1.0 mm to 1.4 mm are commonly used.

6. Can this machine process biodegradable PLA sheet?

Yes. While PLA requires specialized thermal parameters due to its lower glass transition temperature and brittle nature, the VihoX-750’s multi-zone PID temperature controls and adjustable plug assist speeds accommodate food-grade PLA roll stock. A chilled mold temperature controller is recommended when running PLA.

7. What air compressor capacity is required to support the VihoX-750?

The machine consumes approximately 3,000 L/min of compressed air at an operating pressure of 0.6 to 0.8 MPa. We recommend installing an industrial rotary screw air compressor rated at 22 kW to 30 kW (delivering 3.5 to 4.0 m³/min) paired with a 1.0 m³ air receiver tank and a refrigerated air dryer.

8. Does the VihoX-750 come with CE documentation for international customs clearance?

Yes. All VihoX thermoforming machinery complies with European Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU standards. Full CE Declaration of Conformity certificates, electrical schematics, and English operation manuals are provided with export shipments.
