An industrial-control company for extrusion
Founded in 2008, Guangzhou Sealion Software Technology Co., Ltd. is a national high-tech enterprise integrating R&D, manufacturing and sales of industrial control systems. Our work spans hardware EDA, low-level DSP, ARM and host software, electrical-control design, PLC programming and mechanical design — from core algorithms to full-line solutions.

In-house development
Hardware EDA, low-level DSP, ARM and host software, electrical control, mechanical design — we walk the whole chain ourselves rather than integrating other people's boxes.
Core technology held
60 intellectual property registrations, all held by Sealion. The scanning box's auto-tracking probe and the laser diameter device each carry a patent number you can look up.
Low-level algorithms
PID closed loops, adaptive ratio control, DSP echo capture and noise-immune filtering. Whether a reading is right comes down to the algorithm, not a bought-in module.
Of the 60 IP registrations, these invention patents bear most directly on extrusion measurement & control:
- Low-cost visual inspection of surface defects on small-diameter pipe
- Pipe quality inspection equipment and method
- Pipe diameter & thickness gauge and its measuring method
- Calibration method and device for pipe wall-thickness measurement

Exhibitions, certification and customers worldwide
Since first exhibiting at CHINAPLAS in 2015, Sealion's footprint has grown year on year — a steady presence at domestic trade shows, customers across Germany, Iran, Vietnam and Russia, and certifications secured one by one.
CHINAPLAS
Exhibiting at Guangzhou / Shanghai / Shenzhen plastics & rubber fairs every year from 2015 to 2024, meeting the industry face to face.
Overseas exhibitions & customers
K-Show Germany, the Iran and Vietnam plastics fairs, and customer visits from Russia and beyond.
Customer training
On-site training after delivery, so the operations and maintenance team can actually run the system with confidence.
Certificates
IP management system certification, multiple invention patents, CE, ISO9001, National High-Tech Enterprise and Specialised & Innovative Enterprise — the certificates themselves.
It started with one gravimetric control system
Founded in 2008. The first gravimetric control system in 2009, the first ultrasonic thickness gauge in 2010 — everything since has grown out of those two.
