How to control welding precision for large construction machinery frames? Yuexin Machinery's newly added gantry milling machine has shortened export delivery cycles by 15%.

Tangshan Yuexin Machinery Co., Ltd. recently completed a comprehensive upgrade of its workshop equipment, expanding its heavy-duty riveting and welding and precision machining production lines. This significantly enhances its capabilities in custom processing of large non-standard mechanical parts and heavy equipment frames, opening up bulk custom orders to mining enterprises in the Beijing-Tianjin-Hebei region and overseas engineering purchasers.

As a local Tangshan manufacturer with over ten years of experience in metal riveting and welding, Tangshan Yuexin Machinery specializes in processing heavy-duty riveted parts, equipment bases, engineering machinery structural components, mining machinery frames, and heavy-duty supporting parts. Serving steel, cement, mining, and engineering equipment manufacturers, its products are exported to Southeast Asia and Central Asia year-round. The company possesses integrated production capabilities encompassing steel plate cutting, welding, machining, and flaw detection.

This technological upgrade added two 8-meter gantry milling machines, a fully automatic submerged arc welding machine, and ultrasonic flaw detection equipment. These upgrades effectively solve problems related to welding deformation of thick plates and dimensional deviations in large components, controlling workpiece dimensional accuracy within ±0.05mm. The maximum processing weight for a single piece can reach 30 tons, increasing monthly riveting and welding processing capacity by 40%. To address export orders, the company optimized its anti-corrosion coating and standardized export packaging processes, reducing the sea freight delivery cycle from 30 days to 25 days. Overseas customers receive 24-hour after-sales support.

Mr. Wang, the company's production manager, stated, "Domestic and international demand for heavy equipment continues to grow, and customers are increasingly demanding higher precision, faster delivery times, and more comprehensive export documentation for welded structural components. This equipment upgrade establishes a complete quality control system. Each batch of workpieces comes with a flaw detection report and dimensional inspection documents, providing overseas buyers with complete material certificates and factory inspection documents. This meets customer requirements for factory inspections and customs clearance, enhancing the competitiveness of Tangshan's local machinery processing export supply chain." Currently, the company has established long-term partnerships with several equipment manufacturing enterprises in Tianjin and Beijing, simultaneously offering OEM/ODM customization services for export. Customers can provide drawings, and the entire process—from material preparation and welding to precision machining and non-destructive testing—can be completed in one stop, supporting a long-term stable supply of large-scale engineering structural components.
