Project Background: Upgrade Challenges for a World-Class Factory
SAIC-GM-Wuling's Chongqing plant, a benchmark vehicle manufacturing base in Southwest China, operates 108 original German precision machining centers for its cylinder block and cylinder head machining line, undertaking critical processing of core engine components. Driven by market demand for capacity expansion and product upgrading, the customer faced two major challenges:
How to boost annual production capacity to 300,000 units without building new production lines?
How to achieve independent and controllable equipment retrofitting amid technical barriers set by German original manufacturers?
As the first Chinese enterprise to independently undertake this project, Beijing NT Machinery Sales Co., Ltd. delivered results exceeding expectations with strong capabilities.
Our Breakthroughs: Setting a New Benchmark for Chinese Retrofit Solutions
As the general contractor, we completed the systematic retrofit of all 108 German precision machining centers across the entire production line, covering equipment commissioning, process optimization and line coordination, achieving three milestone breakthroughs:
Leap in Capacity, Optimal CostEquipment retrofitting alone lifted the line's annual capacity to 300,000 units, saving the customer hundreds of millions of yuan in new line investment and realizing an efficient upgrade with zero new construction, major enhancement.
Uncompromised Precision, Superior QualityRetrofitted equipment passed SAIC-GM-Wuling's strict verification for machining accuracy and stability, breaking the technical monopoly of overseas brands.
Full-Chain Delivery, End-to-End ControlWe provide one-stop services from solution design, equipment retrofitting and on-site commissioning to after-sales maintenance. Our localized response resolves pain points of long service cycles and high communication costs with overseas manufacturers.
