In the industrial world, damaged molds and rolls are often considered waste, but Ninghai Shengyuan Laser Technology Co., Ltd. has found a way to bring them back to life. By applying a special material over the damaged areas and using high-precision laser technology, they can restore these components and put them back into production. This innovative approach helped the company recover more than 50 million yuan worth of scrapped molds and rolls within just one year. The process begins with a detailed analysis of the original materials used in the damaged parts. Since different types of rolls and molds are made from various materials with differing hardness levels, finding suitable replacements is often a challenge. Many companies simply discard the damaged parts instead of trying to repair them. However, this wasn't the case for Shengyuan. A local manager once faced a critical issue when a Taiwanese-owned factory had to halt operations for over a month due to a shortage of two key rollers. The downtime cost the company around 4 to 5 million yuan, highlighting the urgent need for a better solution. To address this problem, Shengyuan’s technicians developed a unique method. They analyzed the composition of the damaged parts and then mixed raw materials such as iron and magnesium in precise ratios to create a substitute that closely matched the original. To further enhance the repair, the company invested in a high-end German laser system worth 30 million yuan. This laser cladding technology allows for full integration of the new material with the damaged surface, offering a much more durable and effective alternative to traditional methods like plating or flame surfacing. However, the process isn’t without its challenges. The team learned through trial and error that even a small deviation in the mix could lead to failure. For example, during an experiment involving a roll with a hardness of 58 degrees, an extra gram of iron powder caused the material to crack easily. Precision was key, and every element had to be carefully measured and balanced. The benefits of this technology are clear. A local rolling mill previously discarded over 45 pipes each month, costing between 4,000 and 5,000 yuan per unit. With Shengyuan's new method, the cost was reduced to just 10% to 30%, and each pipe could be restored in under an hour. Last year alone, Shengyuan’s roll repair service helped five small steel mills save over 5 million yuan in costs. Experts from Beijing who visited the company were impressed by the quality of the repaired molds and rolls. They confirmed that the performance of the restored parts was not inferior to the original products. This innovation not only saves money for businesses but also promotes sustainability by reducing waste and extending the lifespan of industrial equipment. It’s a perfect example of how advanced technology can turn what was once considered scrap into something valuable again.

Ride On Road Roller

Ride On Road Roller mainly used for compacting soil, trench foundation, large excitation force and high compacting efficiency.
It is ideal for rolling sand, semi-cohesive and cohesive soil, roadbed stable soil and asphalt concrete pavement.

It can also be used for the compaction and leveling of asphalt surface operations, and can be used to compact sand, gravel, soil and asphalt. All can also be said that such a road roller is equivalent to the combination of a single wheel and a double wheel.

For a full hydraulic dual-drive vibratory roller, the steel wheel is involved in both compaction and walking drive, so the load of the steel wheel can be designed to be large, generally accounting for 70% of the weight of the whole machine. it is good. Vibration is the use of high-frequency vibration generated by a vibrator fixed on an object of a certain mass to be transmitted to the pressed material, causing it to vibrate close to its own natural vibration frequency. As the particles approach and the density increases, the material is compacted. Vibration, low surface stress, short process time, large loading frequency, can be widely used for materials with low viscosity, such as sand, cement concrete mixture.
