Why does the high-speed packaging industry need plastic injection machine?

2025/05/10 By Topstar

Plastic milk tea cup production

Deeply influenced by Chinese tea brands, the global tea market has shown a comprehensive and substantial growth. In 2024 alone, the scale of China’s new tea industry has exceeded RMB 300 billion, and is expected to exceed RMB 400 billion by 2028. This growth has driven the simultaneous expansion of milk tea packaging, especially milk tea cups, cup lids, and other outer packaging produced by a plastic injection machine. The demand for these packages requires fast-response manufacturing capabilities, high output rates, and the integration of high-speed automated production lines. To meet these needs, Topstar provides injection molding automation production line solutions for the high-speed packaging industry, combining the high-speed electric drive, modular automation, and remote monitoring functions of plastic injection machines to support the tight production rhythm of the milk tea industry.

Fast and precise production using a plastic injection machine

High-speed packaging production requires both output and precision. The high-speed all electric injection molding machine can well reflect this balance in this solution. With an eight-cavity mold and a fast cycle of 7.2 seconds, each plastic injection machine can produce more than 14,400 milk tea cups per day, more than 15% higher than the output of traditional machines. In addition, when operators run multiple devices in parallel, they can linearly expand the output to flexibly cope with the peak season.

In addition to delivering strong output, this plastic injection machine ensures dimensional accuracy, enabling it to produce leak-free cup lids and maintain consistent cup wall thickness. Its discrete intelligent drive injection unit optimizes melt flow and holding pressure to produce uniform, consistent packaging products that meet strict beverage safety regulations.

Modular design for increased flexibility

To solve the problems of surging order volume, complex equipment in the production workshop, and space constraints, Topstar’s plastic injection machines adopt an integrated modular design, reducing the factory footprint by up to 50%, allowing operators to change settings flexibly. The compact injection molding unit, servo-driven robots, and auxiliary equipment can connect seamlessly with the plastic injection molding machine without large-scale factory modifications or additional infrastructure.

At the same time, the modular architecture can also support rapid reconfiguration, without much downtime to switch from cup production to lid or other injection molding machine-based packaging component production. This flexibility enables manufacturers to quickly adapt to changing product lines or promotional packaging needs and maximize equipment utilization.

Smart trajectories bring automated production.

In the high-speed packaging industry, uninterrupted operation is required to ensure output. Intelligent trajectory control of manipulators and robots is integrated into the injection molding automation production line solution to ensure that parts disassembly, post-processing, and assembly are carried out simultaneously, to monitor cycle changes in real time, dynamically adjust the robot path, ensure seamless handover, and prevent production line downtime. Through a unified communication language, plastic injection machines can continuously share performance data with the central control system to achieve predictive maintenance, minimize unplanned downtime, avoid costly delays, and maintain product supply during peak demand.

Remote monitoring and intelligent maintenance

Topstar’s plastic injection machine ecosystem provides cloud-based remote operation and maintenance, allowing operators to instantly view machine status, cycle times, and energy consumption anytime, anywhere. The real-time dashboard highlights abnormal conditions such as pressure deviation or temperature drift, allowing operators to take diagnostic measures quickly before defects occur.

This intelligent maintenance framework reduces labor costs and extends the service life of key components. Both heaters and servo motors can receive data-driven life cycle recommendations to ensure that each injection molding machine can operate optimally. Thus, engineers create a robust and scalable injection molding solution for the high-speed packaging industry.

Each plastic injection molding machine can produce 100,000 pieces per day.

Under normal conditions, a single-speed electric injection molding machine can produce more than 100,000 milk tea cups daily. Manufacturers can increase the output of production facilities by up to 20% by combining multi-cavity molds, fast injection molding control, and synchronous automation. These powerful indicators enable the high-speed packaging industry to meet unprecedented peaks in consumer demand and quickly launch new products. In addition, the precision molding capabilities of plastic injection molding machines minimize material waste and shorten molding cycles, thereby reducing unit costs. In the labor-intensive and profit-sensitive beverage industry, they will translate into a competitive advantage.

Comprehensive solutions for high-speed packaging

The trend of large-scale growth in milk tea cups highlights the need for the high-speed packaging industry to adopt advanced injection molding machine technology. Using fast electric drives, modular system design, intelligent automation, and remote maintenance in Topstar’s injection molding automation production line solutions can solve key pain points from production scale to quality consistency. Manufacturers can easily cope with peak season pressures by leveraging these features and achieve product diversification.
