Plastic cup making machine is a fully automatic industrial machine that is utilized to produce high volumes of disposable plastic cups and food containers. This kind of plastic cup thermoforming machine is packaged as both a commercial use tool and functions to package plastic sheet into the final cup-shaped products through built-in conveying, heating, forming, and cutting, so that its output remains consistent, and quality remains the same.

Being a high-efficiency cup maker machine, it has a forming-and-cutting two-in-one design that envisions the production process to be completed within one process. Superior control systems control temperature, shape, form, pressure, and cut accuracy and minimize human intervention as well as enhancing production consistency, energy usage, and sound reduction. The equipment is used to allow an endless operation of beverage, dairy, and foodservice packaging lines.

This plastic cup production machine can be used to process PP, PS, PET, and PVC plastic sheets, among other plastics. It has the capability to manufacture disposable drink cups, coffee cups, milk tea cups, plastic bowls, plates and lids as well as jelly cups. Included with the ViHox 1-stop solution of machines, extruders, molds, and auxiliary equipment, it assists the manufacturers in constructing scalable and CE accredited plastic packaging manufacturing lines.

Plastic Cup Forming: Principle & Process

In a plastic cup making machine, cup formation is achieved through a controlled thermoforming process.The thermoplastic sheets are heated to a forming temperature and then positioned correctly on the area of the mold. Mechanical plug is then used to stretch the softened sheet, and compressed air is used to press the material against the mold cavity.

After the cup shape has been completed, the cutting system removes the product to its size. The mold is then automatically opened and the completed cups loaded onto the downstream stacking system. This repeated forming and cutting process enables a plastic cup production machine to have high efficiency and quality products.

Mold Structure And Integration

The mold is very much an inbuilt part of the system. It integrates the processes of pressing, forming, trimming, cooling and product release. This mold design reduces the cycle time, enhances dimensional accuracy and enables a stable operation over the long production cycles.

Key Functional Features Of Our Servo Plastic Cup Machine

Our plastic cup manufacturing machine is entirely servo-motorized, and thus it operates very smoothly and without noise and vibration, even when operating on a high rate of production. The servo system provides accurate motion control, which enhances the accuracy of the forming and increases the service of the machine.

The machine has a small structural layout and occupies less space on the floor, in addition to incorporating a sheet feeding system, heating, stretching, forming, and trimming as a single process. The production parameters can be altered using an automatic unloading system, which will help to reduce the waste of materials without providing an unnecessary production.

The smart temperature control system is used in a one-to-one in the electric heating furnace that provides uniform heating of the plastic sheet. This design enables energy-saving, speedy temperature reaction and constant forming conditions. Servo-driven forming/cutting molds have bi-directional stroke control, and the upper mold closing direction is electrically adjustable to enable a rapid change in height and a low vibration, smooth operation.

Under PLC-based control, the machine automatically cuts, counts, and transfers the products. Final packing requires only one or two operators because it is highly automated, which decreases the handling of labor in the production lines of the plastic mug making machines.
