Subtitle: All-in-one decoiling, leveling, feeding and shearing solution cuts factory footprint and energy consumption for automotive, appliance and mold manufacturing DONGGUAN, China – June 2026 — YUANJIA Machinery has launched an upgraded 4-in-1 servo coil processing system that integrates decoiling, leveling, feeding and shearing in one compact unit. Built to resolve traditional stamping line pain points including large floor occupation, cumbersome multi-machine coordination and material waste, the new equipment delivers higher efficiency, better precision and lower operational costs for modern smart manufacturing. Traditional metal coil processing requires separate machines for uncoiling, straightening, feeding and cutting, resulting in frequent process switching, excessive space usage and residual waste on coil heads and tails. To address these industry challenges, YUANJIA upgraded its mature three-in-one platform and added an independent servo shearing module, creating a unified intelligent production system suitable for home appliance, mold, automotive parts and decoration material manufacturing. Maximum Efficiency & Cost Reduction with Integrated Four-Function Design The newly launched 4-in-1 system realizes fully coordinated operation of all functional modules, eliminating repeated positioning and connection errors caused by multiple independent devices. Its exclusive integrated shearing function brings two core advantages: automatic cutting of coil head and tail waste to improve material utilization,

For manufacturers dealing with long stamping lines like automotive anti-collision beam or kitchenware production, coil changeovers have long been a bottleneck—until now. Our automatic shearing and butt welding machine, as shown in the complete stamping line demo, solves this pain point by seamlessly connecting coil ends without manual intervention. Integrated with uncoilers, levelers and servo feeders, this machine uses touch-screen control to automate the whole process: shearing the coil tail, aligning and welding the new coil head in one go. It eliminates the downtime and labor costs of manual coil joining, keeping even the longest production lines running continuously. Designed for high-strength steel coils used in automotive parts and the thin, uniform materials needed for kitchenware, it delivers clean, reliable welds that won’t disrupt downstream stamping or roll forming. This isn’t just a welding machine—it’s the key to turning your stamping line into a lights-out, high-efficiency operation.

As the automotive, consumer electronics, and aerospace precision manufacturing industries continue to advance rapidly, manufacturers face increasingly stringent requirements for the flatness, dimensional accuracy, and consistency of metal hardware components. While high-speed stamping and laser cutting enable efficient mass production, they often leave finished parts with minor warping, surface bending, and micro deformation issues. Traditional metal straightening machines are unable to deliver ultra-precision correction, creating a critical quality bottleneck for high-tolerance precision component production. To resolve these common manufacturing pain points, our precision parts leveler adopts professional high-precision flattening technology, effectively eliminating part deformation defects and enabling reliable quality upgrading for diverse precision metal processing applications. Tailored for precision small components, thin-walled metal parts, and flat sheet metal workpieces, this precision parts leveler features a premium four-roll flattening configuration and a full-covered back pressure wheel system. This optimized structural design ensures even pressure distribution and exceptional overall rigidity, delivering accurate correction of all types of micro deformations without workpiece scratching or secondary distortion. It perfectly addresses the typical drawbacks of conventional straightening equipment, such as limited precision, poor part adaptability, and low production yield. As a result, it significantly boosts the overall machining quality and flatness precision of finished metal

As global automotive OEMs accelerate their lightweighting initiatives, Advanced High-Strength Steel (AHSS) has transitioned from an alternative material to the dominant standard for safety-critical structural components. Cross beams, A/B pillars, anti-collision beams, and side-impact reinforcements are now routinely manufactured from material grades ranging from 800MPa dual-phase (DP) steel to 1500MPa press-hardened steel (PHS / 22MnB5). While these materials deliver exceptional strength-to-weight ratios, they introduce a manufacturing challenge that many stampers underestimate: AHSS coils retain significant internal stresses from the cold rolling and annealing processes, manifesting as edge waves, center buckles, longitudinal curl, and cross-bow. When these defects enter a stamping die without proper correction, they amplify under forming pressure, producing dimensional deviations of several millimeters, unacceptable surface quality, and in severe cases, complete part rejection. The Yuanjia 300-1300HSS Precision Leveling Machine is specifically engineered to address the AHSS flatness challenge. It achieves flatness control of ≤0.1mm per square meter and handles yield strengths up to 1500 MPa — covering the full range of AHSS and ultra-high-strength steel (UHSS) grades used in modern automotive platforms. The machine’s 21-roller three-stage precision straightening system is the technological heart of the solution. The process is divided into three functional zones: the front section employs

A typical automotive cross beam production line spans 50 to 60 meters, integrating decoiling, straightening, feeding, stamping, and roll-forming operations. In such extended-process layouts, the most devastating efficiency killer is rarely the cycle time of any individual machine — it is the coil change downtime. Conventional single-head uncoilers require operators to stop the entire line, thread out the remaining tail, hoist a new coil, clamp and expand it, feed the leading edge through the straightener, and re-establish tension before production can resume. This entire sequence consumes 15 to 30 minutes even for experienced operators. With 4 to 6 coil changes per day on a busy cross beam line, the cumulative non-production time reaches 1 to 3 hours every single day — a silent but substantial drain on capacity and revenue. The Yuanjia KHT Series Double-Head Uncoiler is purpose-built to eliminate this bottleneck entirely. Its core design philosophy centers on dual-station alternating feeding with zero-downtime coil switching. Each station features an independently driven spindle powered by a Siemens variable-frequency motor with a dedicated inverter. A hydraulic expansion mechanism accommodates coil inner diameters from 460mm to 530mm, with a maximum outer diameter of 1600mm. While one station is actively feeding material into

Roll rolling production lines are widely used in the manufacturing of automotive crossbeams, anti-collision beams, and logistics shelves. These production lines consist of multiple pieces of equipment such as uncoilers, levelers, feeders, punch presses, rolling mills, and shears. As a result, the production lines are extremely long, ranging from 20-30 meters in the short case to 50-60 meters in the long case.​Trying to bring a coil head to the end of the production line is an extremely labor-intensive task. At this point, we can choose the automatic butt welding machine we produce. We usually place it between the leveler and the feeder. It can automatically weld the heads and tails of two coils of materials together, thereby significantly reducing the manual material threading time, improving production efficiency, and greatly enhancing production safety.​For enterprises engaged in the production of automotive crossbeams, anti-collision beams, and logistics shelves, the length of the roll rolling production line has always been a challenge in the production process. The manual material threading work not only consumes a lot of labor but also affects the continuity of production. The emergence of the automatic butt welding machine has effectively solved this problem.​By automatically connecting the material heads and
