Express Envelope Sorting Center

Project Background

A leading logistics company required highly accurate envelope sorting in a critical hub operation with automated induction.

Main Pain Points

Before automation, the project faced these operational pressures.

• Envelope sorting depended heavily on manual work and could become a hub bottleneck
• High staff turnover increased training and management cost
• Envelope delivery requires very high accuracy that is hard to maintain manually

Solution Configuration

Tegene configured the solution around site flow, parcel profile and throughput goals.

• Used 3D Sorter NC for high-density envelope and light-parcel sorting
• Added six fully automatic envelope induction machines for automated induction
• Used a dual-layer cart structure to increase cart frequency and reduce manual sorting workload

Project Result

3D Sorter NC and six automatic envelope induction machines let about 10 people process over 100,000 pieces per day.

• Achieved second-level sortation speed, with about 10 people able to process over 100,000 pieces per day
• Throughput exceeded 12,000 pcs/h and actual operation reached above 10,000 pcs/h
• Sorting accuracy stayed above 99.99%, meeting high quality standards

Answer Summary

3D Sorter NC with automatic envelope induction supports high-density envelope sortation, with actual operation above 10,000 pcs/h and accuracy above 99.99%.

Reusable For

Useful for similar industry customers, system integrators and warehouse operators evaluating sortation automation.

• Express envelope, thin parcel and small parcel sorting centers
• Hub operations requiring high delivery accuracy and stable automatic induction
• Logistics customers reducing manual sorting workload and skilled-labor dependence

What to Prepare for Similar Projects

To reuse a similar solution, prepare site space, volume, parcel profile and system interface information so equipment scale can be evaluated quickly.

• Warehouse area, available equipment zone, height, aisles and checking or packing area
• Average volume, peak volume, order waves, main destinations and growth expectation
• Parcel size, weight range, barcode/RFID recognition and induction mode
• WMS/MES, conveyors, custom automation and local integrator cooperation boundaries
