In October 2025, industry analysis reports show that global demand for pulp molding packaging continues to rise. Driven by the threefold impetus of deepened "plastic ban" policies worldwide, tightened "dual-carbon" regulations, and the full penetration of sustainable development concepts, the intelligent and automated upgrading of pulp molding equipment has become the core direction of industry transformation. As a leading enterprise with 35 years of experience in the industry, Guangzhou Nanya Pulp Molding Equipment Co., Ltd. (hereinafter referred to as "Guangzhou Nanya"), relying on technical accumulation since 1990, has built a matrix of practical intelligent equipment centered on the new-generation intelligent fully automatic pulp molding production line. It helps packaging enterprises around the world build efficient, low-carbon, and flexible production systems, emerging as a key force driving the upgrading of the pulp molding industry.
Traditional pulp molding production lines generally suffer from pain points such as manual-dependent parameter adjustment, extensive energy consumption control, slow response to production changeovers, and poor product consistency. Especially in segmented fields like eco-friendly pulp tableware production lines and pulp molding egg tray production lines, they struggle to meet the flexible production needs of smart factories. To address these issues, Guangzhou Nanya has developed a new-generation intelligent fully automatic pulp molding production line, which innovatively integrates three core modules: KUKA robots, intelligent temperature control systems, and energy-saving drying systems:
- KUKA robots handle automatic product grabbing, stacking, and transportation, replacing traditional manual operations and reducing labor input by 60%.
- The intelligent temperature control system monitors mold cavity temperature in real time with a precision of ±2℃, ensuring uniform hot-pressing effects of in-mold hot-pressing machines on products such as lunch boxes and egg trays.
- The energy-saving drying system significantly reduces comprehensive energy consumption compared with traditional pulp molding drying equipment, and optimizes steam consumption per unit product remarkably.
The production line is also equipped with a high-precision vacuum adsorption molding machine and an automatic pulp supply adjustment system:
- The former uses a combined positive and negative pressure pulp suction process to ensure uniform pulp deposition on customized pulp molding molds. It is compatible with various raw materials such as bagasse pulp, wood pulp, and bamboo pulp, and can produce a full range of products—from 100ml small-capacity cup lids to 2000ml large-capacity soup bowls.
- The latter automatically adjusts pulp supply speed and flow based on pulp concentration and fiber length. Combined with online concentration detection sensors, it stabilizes the product qualification rate above 99%, far exceeding the industry average.
In terms of intelligent management, the production line is deeply integrated with a PLC+HMI control system, enabling automatic collection and visual presentation of key data throughout the entire process—from the pulp pulping system, forming, and hot-pressing to drying. Managers can grasp production capacity, energy consumption, mold temperature, and quality control data in real time through the central control screen, and accurately control the production rhythm without manual inspection. To meet the demand for multi-category production, the production line is equipped with a quick mold change device. Through standardized mold interfaces and automatic positioning technology, it can flexibly switch between product specifications such as pulp molding lunch boxes, egg trays/fruit trays, and industrial buffer liners, perfectly adapting to the characteristics of small-batch and multi-batch orders and solving the problems of "difficult and time-consuming production changeovers" in traditional production lines.
As a national high-tech enterprise and vice-chairman unit of the Pulp Molding Branch of China Packaging Technology Association, Guangzhou Nanya has always taken technological innovation as its core competitiveness:
- It has established a professional R&D team of over 20 members, with annual R&D investment accounting for more than 5%. In 2025, it has obtained a number of practical technology patents, including intelligent pulp supply adjustment devices, energy-saving pulp drying modules, and quick mold change positioning mechanisms.
- It owns three core bases: the Guangzhou R&D Center, the Robot Assembly Base, and the Foshan Machinery Manufacturing Center. The entire equipment production process complies with ISO9001 quality standards, ensuring the stability and reliability of each piece of pulp molding equipment.
Currently, Guangzhou Nanya's intelligent pulp molding production lines have served packaging enterprises in more than 80 countries and regions worldwide, providing customized solutions covering fields such as eco-friendly pulp tableware production, fresh egg tray manufacturing, and electronic industrial packaging:
- Domestic customers have used its equipment to respond to the "bamboo replacing plastic" policy, increasing the production capacity of bamboo pulp lunch boxes by 40%.
- Overseas customers have successfully entered the European and American markets with degradable packaging produced by its production lines, avoiding the risk of "anti-dumping and countervailing" tariffs.
Against the backdrop of accelerated promotion of smart factory gradient cultivation policies, Guangzhou Nanya will continue to optimize the intelligence and low-carbon level of its equipment, promoting the iteration of pulp molding equipment toward higher precision, better energy efficiency, and stronger flexibility, and helping the industry achieve efficient and environmentally friendly production transformation.
