E-Bike & Bicycle Polyurethane Tire Production Line Intelligent Upgrade

Project Overview

Jiangxi Songji Sports Technology Co., Ltd. is a specialized manufacturer of polyurethane centrifugal-molded bicycle tires, offering standard bicycle tires, wheelchair tires and lightweight solid e-bike tires. The company operated 4 traditional semi-automatic centrifugal casting lines with a designed annual capacity of approximately 7.5 million tires. As the high-end e-bike market expanded, requirements for tire wall uniformity, dimensional consistency, durability and high-volume delivery increased. The existing equipment suffered from insufficient metering precision, poor casting-centrifuge synchronization, heavy reliance on manual operation and limited production data traceability. Haifeng Automation therefore implemented a comprehensive intelligent upgrade across all 4 casting stations and supporting production lines.

Solutions Delivered

Haifeng Automation upgraded the customer’s 4 traditional semi-automatic casting stations with an intelligent centrifugal casting solution designed for high-precision polyurethane bicycle and e-bike tire production. The solution integrates full-servo closed-loop metering, dynamic casting-centrifuge synchronization, automated production processes, industrial IoT data management and predictive maintenance. More than 30 standardized process formulas for mainstream tire sizes are stored in the control system for one-click selection and rapid changeover. The system also collects 12 core process indicators for real-time monitoring, automatic alerts and full-process quality traceability, while optimized metering pumps and injection nozzles reduce energy consumption and maintenance requirements.
