Opening on the Pain Points of Industry Technology
In large-scale infrastructure projects such as expressways and high-speed railways, there is a high demand for steel arch frame processing with stringent precision requirements. Traditional processing methods rely on manual operations and have the following pain points:
STEP 1: Insufficient accuracyManual cutting and welding are prone to errors, leading to dimensional deviations in the arch frame and affecting structural stability;
STEP2: InefficiencyThe long processing time for a single piece makes it unable to meet the demands of large-scale projects;
STEP 3: High CostsLabor costs, material waste, and an increasing rework rate have driven up overall costs.
How to overcome these pain points and achieve efficient and precise processing of steel arches has become a technical challenge urgently needing resolution in the industry.
