Petri Dish Injection Extraction + Automatic Lid Assembly + Stacking + Bagging Automation Solution

Petri Dish Take-Out + Lid Assembly + Stacking + Bagging Automation Solution

Addressing the needs in petri dish production such as large product quantities, low efficiency of manual lid assembly, high requirements for stacking consistency, and high labor costs in the packaging process, SWITEK launches the integrated automation solution for petri dish injection extraction + automatic lid assembly + stacking + bagging.

The system uses the injection molding machine as its core. Through side-entry automation equipment, it completes simultaneous extraction of petri dishes and dish lids, and automatically transports products to the lid assembly station. The system completes precise positioning and automatic snapping of petri dishes and lids according to preset programs, then organizes, counts, and stacks the assembled products, and automatically transfers them to the packaging station to complete bagging and subsequent packaging.

Addressing the requirements of petri dish production for product cleanliness, appearance consistency, and production stability, the entire system replaces a large amount of manual operations with automation equipment, reducing manual contact with products during the production process, achieving continuous production from injection molding, product extraction, automatic lid assembly to stacking and packaging, and improving production efficiency and product consistency.

The system can be customized according to different petri dish specifications, mold cavity counts, production rhythms, and packaging requirements, supporting various mold configurations such as 6+6 and 8+8, and is suitable for large-batch, high-efficiency automated production of petri dishes.

Core Advantages

Injection Extraction Automation

Adopting a side-entry automation system, it efficiently completes automatic extraction and transfer of petri dishes and dish lids, reducing manual operations and improving production rhythm stability.

Automatic Precise Lid Assembly

Through a dedicated lid assembly mechanism, it achieves automatic positioning and snapping of petri dishes and lids, ensuring stable lid assembly actions and neat product arrangement.

Automatic Stacking and Counting

After lid assembly, products automatically complete counting, organization, and stacking, and stacking layers can be flexibly set according to customer packaging quantity requirements.

Automatic Bagging

After stacking is completed, products automatically enter the packaging station, achieving automatic bagging, reducing manual packaging, and improving overall production efficiency.

Reduced Manual Contact

From injection extraction to final packaging, multiple processes achieve automated connection, reducing manual handling and operation frequency, helping to improve production environment cleanliness and product consistency.

High-Efficiency Stable Production

The injection molding machine, extraction system, lid assembly mechanism, stacking mechanism, and packaging system operate in coordination, achieving unified production rhythm and adapting to large-batch continuous production of petri dishes.

Flexible Configuration

System design can be performed according to petri dish size, mold structure, cavity count, cycle time, and packaging method, meeting the automated production needs of products with different specifications.
