When performing weld buildup on ductile cast iron, there is a problem where a high-carbon, high-hardness dilution layer is formed due to welding dilution, making cracking and peeling more likely to occur. However, by applying the low-dilution laser buildup method, the intermediate hardened layer and heat-affected zone can be minimized compared to conventional semi-automatic buildup, reducing the risk of cracking and peeling. Furthermore, by obtaining a higher hardness buildup layer, improved wear resistance can also be expected. 【Features】 ■ Minimizes the intermediate hardened layer and heat-affected zone compared to conventional semi-automatic buildup ■ Reduces the risk of cracking and peeling ■ Achieves wear resistance by obtaining a higher hardness buildup layer *For more details, please refer to the PDF document or feel free to contact us.

"Composite Laser Cladding with Ceramic Particles" is a cladding welding method that uses lasers capable of welding at lower temperature ranges than conventional welding methods, allowing for the incorporation of ceramic particles into the cladding layer while maintaining the shape of the particles without melting them. By optimizing the laser heat input, it is possible to incorporate ceramic particles without decomposition. Since the ceramic particles remain unwelded, the cladding layer can possess the physical properties of both ceramics and metals. [Features] - Incorporates ceramic particles into the cladding layer while maintaining their shape without melting them. - Ceramic particles and metal matrix can be selected according to application and purpose. - By optimizing the laser heat input, it is possible to incorporate ceramic particles without decomposition. - Since the ceramic particles remain unwelded, the cladding layer can possess the physical properties of both ceramics and metals. *For more details, please refer to the PDF document or feel free to contact us.

The "Semiconductor Laser Cladding" by Shin Nihon Yogyou Co., Ltd. is a construction technology that allows for buildup at a low heat input (2,500°C) compared to conventional methods. Due to the low heat input, it reduces thermal distortion and heat-affected zones. Benefits such as reduced post-processing costs from near-net shape laser cladding and performance improvements from high-quality, high-material-property surface modification layers due to low heat input and low dilution laser cladding can be expected. 【Features】 ■ Allows for buildup at low heat input (2,500°C) ■ Capable of thin buildup (0.4mm) comparable to thermal spraying ■ Reduces thermal distortion and heat-affected zones due to low heat input ■ Achieves a buildup layer with high hardness and high purity ■ Compared to PTA buildup, laser cladding has a penetration depth of 1/5 *For more details, please refer to the PDF document or feel free to contact us.

The "SNYG Extruder" is a volume reduction compression molding machine that employs a three-screw design, enabling solidification at a high compression ratio. By changing the number of extrusion nozzles, the compression ratio can be adjusted. It is also compatible with high moisture content materials. Additionally, utilizing advanced wear-resistant technology, the volume reduction solidification screw can be optionally changed to the wear-resistant material "ROCK-WEL." This allows for prolonged continuous operation and reduced maintenance costs. 【Features】 ■ Achieves high-density solidification through volume reduction compression with a two-axis three-screw design ■ Capable of handling moisture content rates of 20% or more ■ Compact design with volume reduction sections that are half the size of conventional models ■ Various shapes can be achieved in volume reduction compression molding by exchanging the extrusion nozzles ■ By changing to an optional inverter drive, the rotation speed of the volume reduction screw can be freely adjusted *For more details, please refer to the PDF materials or feel free to contact us.

"Quick Tip" is a small sintered piece made of hard metal (WC-Co) that significantly enhances the toughness of the base material surface when applied through welding. Due to the three-dimensional nature of the bonding surface, it has low peeling properties and ensures sufficient bonding strength. Additionally, the wear resistance is handled by the hard metal block, while the toughness is provided by the alloy within the minute gaps, allowing for the realization of a surface that is both hard and flexible, which has been an ideal goal. [Features] ■ High bonding strength ■ Resistant to thermal shock ■ Excellent toughness and wear resistance ■ Applicable to any shape *For more details, please refer to the PDF document or feel free to contact us.

The "ROCK-CUTTER" is a hybrid industrial cutting tool that has undergone surface modification through special build-up welding. The cutting edge has been treated with build-up welding and special heat treatment, resulting in a hardness of approximately Hv900, comparable to high-speed steel, in the surface layer of about 3mm. The interior of the tool is maintained at a hardness of around Hv500 to ensure toughness, effectively preventing tool breakage during foreign object intrusion. Additionally, it can be adapted as a cutting tool material for various crushers. 【Features】 ■ Uses our original special welding material for build-up welding ■ Strong against impacts from foreign object intrusion ■ The cutting edge is hard, while the interior is strong and flexible ■ Hardness of the cutting edge can be freely adjusted according to the material being processed ■ Comprehensive maintenance for crushers is also available *For more details, please refer to the PDF document or feel free to contact us.
