INTRODUCTION

The Plastic Cup Lid Making Machine is a high-performance specialized equipment developed on the basis of Plastic Thermoforming Machine technology, focusing on the efficient production of plastic cup lids for the beverage, catering, and food packaging industries. With the continuous growth of the disposable packaging market, the demand for high-quality, high-speed cup lid production equipment is increasing, and this machine is designed to meet these market needs with its advanced engineering and automated design.
This Plastic Cup Lid Making Machine adopts multi-station thermoforming technology, which is a core advantage inherited from the advanced Plastic Thermoforming Machine. It is mainly provided in three-station and four-station models to adapt to different production scales and product requirements. The four-station model is particularly suitable for large-scale mass production, as its integrated punching station can efficiently complete the cutting of cup lid edges and the punching of vent holes, eliminating the need for additional post-processing procedures and greatly improving production efficiency and product consistency.

In terms of performance, the Plastic Cup Lid Making Machine excels in both speed and material flexibility. It can process a variety of food-grade plastic sheets, including PP, PET, and PS, which are the main materials used in plastic cup lid production. For thin-gauge PET sheets, which are preferred for their clarity and rigidity, the machine can operate at a maximum speed of 45 molds per minute; for PP sheets, which are known for their flexibility and heat resistance, the maximum speed is around 30 molds per minute. The actual production speed is affected by factors such as the depth of the cup lid and the thickness of the sheet, with shallower lids enabling higher speeds.

The Plastic Cup Lid Making Machine is also equipped with an intelligent control system and a parameter save function, which simplifies operation and improves production stability. When a new cup lid mold is used, engineers only need to debug and optimize the operating parameters once, and the parameters will be permanently stored in the machine. When the same mold is used again, the machine can automatically recall the parameters, ensuring consistent product quality and reducing the time and labor cost of repeated debugging. This feature makes the machine an ideal choice for enterprises engaged in large-scale cup lid production.
