Pulp Molding Production Line For Tableware Production

Pulp molded tableware includes food containers, bowls, trays, plates, cutlery (knives, forks, spoons), paper cups, self-heating meal boxes, and takeaway packaging. These products feature a clean design, strong pressure and bend resistance, light weight, and easy storage. They are waterproof, oil-resistant, microwave-safe, and freezer-friendly-ideal for modern eating habits and fast food needs. As a biodegradable alternative to plastic, pulp molded tableware is both eco-friendly and practical. The Pulp Molding Production Line enables efficient, large-scale production of these sustainable items.

Pulping System

According to different product requirements, we equip the pulping system with an automatic feeding unit. The entire system is controlled by a PLC, achieving full mechanical-electrical-pneumatic integration to realize automatic pulp preparation and pulp supply.

To meet the specific production needs of our customers, the system is capable of real-time monitoring of pulp concentration, enabling online concentration control to ensure smooth and stable production.

Based on feedback from the online quality control of finished products, the pulping system can be adjusted in real time to maintain optimal performance.

Forming Process – Quantitative Slurry Injection Molding

The forming process adopts a quantitative slurry injection molding method, where a measured amount of pulp is injected into the forming mold cavity and shaped through vacuum adsorption.

Advantages of Slurry Injection Molding:

Lower Equipment Cost
Compared to the traditional vacuum suction molding method, this structure is simpler, with lower maintenance costs.

Stable Product Quality
Ensures consistent product weight and thickness, making it especially suitable for tableware products with high precision requirements in size and weight.

Reduced Pulp Waste
Minimizes pulp waste caused by over-adsorption or uneven distribution, thereby reducing production costs to a certain extent.

Six-Axis Robotic Handling System

The system utilizes a high-end KUKA six-axis robot, offering the following advantages:

High Load Capacity
Capable of handling payloads up to 500 kg, with optional configurations supporting 1,000 kg or more, meeting various heavy-duty production needs.

High Precision
Equipped with advanced sensors and cutting-edge algorithms, the system achieves high-accuracy positioning and repeatability, ensuring consistent performance.

User-Friendly Operation
Operated via a PC-based control platform with an intuitive interface, the system supports flexible programming and high-speed calibration-able to reset all six axes to zero within one minute.

Excellent Environmental Adaptability & High Safety
Designed to perform reliably in various industrial environments, the system features robust safety measures to ensure secure operation.

Vacuum System, Compressed Air System, and High-Pressure Water System

The vacuum pump uses a permanent magnet variable frequency energy-saving vacuum pump.

The variable frequency vacuum pump automatically adjusts the motor speed according to actual operating conditions, precisely matching the air extraction rate.

This design typically saves 30%–50% energy, eliminates the need for water usage, and produces no wastewater discharge, making it environmentally friendly.
