Supply & Demand

This significantly enhances part consistency and overall yield rates. Equipped to perform at the level expected of an automatic tube & pipe re-rounding machine for stainless steel and thin wall tubes, the system integrates high-accuracy sensing technology, an intelligent servo control platform, and a precision mechanical transmission structure. Together, these components form a fully closed-loop control architecture—from real-time data acquisition and computational analysis to precise motion execution. The result is continuous in-line monitoring, automatic deviation compensation, and accurate control of critical parameters such as outer diameter, inner diameter, roundness, straightness, and wall thickness uniformity. Supported by advanced control algorithms and a high-rigidity machine frame, the equipment maintains stable precision output even during extended continuous production runs. It effectively eliminates common issues found in traditional machines, including ovality, eccentricity, surface scratching, and dimensional fluctuation. Each finished component consistently meets stringent industry quality standards. For manufacturers in automotive, fluid transmission systems, home appliances, and precision hardware sectors, this ensures dimensionally accurate, performance-stable, and quality-consistent base tube components—ultimately safeguarding downstream assembly accuracy and long-term product reliability.

The DN50 Unilateral Tube Upsetting Machine is a single-station precision forming equipment developed by Yanruilin specifically for end upsetting, thickening, and profiling of small-to-medium metal pipe fittings. Featuring a rigid heavy-duty frame and a powerful single-side extrusion upsetting mechanism, the machine is dedicated to end thickening, flaring, swaging, flanging, and marmon beading forming on materials including stainless steel, carbon steel, aluminum alloy, and copper. It serves a wide range of industries such as plumbing, gas fittings, automotive tubing, refrigeration systems, and hardware manufacturing, offering a dependable solution for local end reinforcement and precision forming.

Adopting a vertical structure and single-station and double-station precision extrusion forming mechanism, it integrates Swiss profile extrusion technology. It is suitable for forming processes such as single press fitting, ring pressing, flaring, reducing, bead forming, flanging and Marmon forming of stainless steel, carbon steel, aluminum alloy, copper alloy and other pipes. Balancing batch production stability and process versatility, it serves as core equipment for medium and large pipe forming in plumbing & gas, construction piping, automotive pipelines, shipbuilding, air conditioning and refrigeration industries.
