"SEP processing" is a surface treatment technology that allows for the dissolution of surfaces by simply immersing products in a special liquid, enabling the removal of burrs and adjustment of surface roughness. Since it does not apply external shocks such as vibration or friction, it can process thin and fine parts without deformation, dents, or distortion. It accommodates a wide range of metals, including iron and stainless steel, and can uniformly treat difficult-to-polish areas such as grooves, tiny holes, and uneven surfaces. It solves delicate burr issues that have been previously given up on, such as "difficulty in processing fine burrs," "complex shapes or thin materials that bend or deform," and "difficulty in finishing the roughness of deep holes or the inner diameter surfaces of pipes." It contributes to the miniaturization of parts. 【Features】 - Can process thin sheets without deformation, dents, or distortion - Simultaneously removes fine burrs, polishes, and cleans - Addresses the removal of fine cracks and unevenness on part surfaces - Dimensional changes before and after processing can be managed in microns - Can also be utilized for contamination and dust removal ★ If you are interested in prototypes, please feel free to contact us! ★ *For more details, please refer to the PDF materials or feel free to contact us.*

The advantages of press processing are mass production in a short time using molds. If burrs become an issue, full inspection and rework of all items become necessary. Additionally, removing burrs from products that are bent or drawn in complex shapes is very difficult. With SEP processing, it is possible to process a large quantity at once, allowing for burr removal in a short time and at a low cost. Even products with complex shapes can be processed. Moreover, the burrs generated during press processing often occur in the same location and are of nearly the same size, making it possible to guarantee almost all items by keeping the processing conditions constant and conducting sampling inspections. 【Challenges of Press Processing】 ■ If burrs become an issue in mass production through press processing, full inspection and rework of all items will be necessary. ■ Removing burrs from products that are bent or drawn in complex shapes is very difficult. *For more details, please refer to the PDF materials or feel free to contact us.

Have you ever experienced this with deburring of fine holes (Φ0.1mm or less) + polishing of the outer diameter and inner diameter (entire surface)? "We couldn't accept orders because deburring was difficult due to numerous fine hole processes." "We gave up because the roughness of the inner diameter couldn't be finished." "Deburring occurs on the surface when chamfering due to the small hole diameter." With SEP treatment, it is possible to deburr the entrances and exits of fine holes, polish the inner diameter, and enlarge (at the micron level). [Case Study] ■ Before treatment: Overall rough feeling with poor light reflection ■ After treatment: No rough feeling as before, with much better light reflection *For more details, please refer to the PDF document or feel free to contact us.

HVOF (High Velocity Oxygen Fuel) refers to high-velocity flame spraying, which is one method of thermal spraying. Unlike conventional spraying methods, the particle velocity is extremely high, resulting in a dense and well-adhered coating with fewer oxides and pores. Additionally, the flame temperature of HVOF is approximately 2400–2600K, which reduces the decomposition of WC, allowing WC cermet coatings to be sprayed in areas where wear resistance is required. 【Features】 ■ The mixed gas of oxygen and fuel (kerosene) burns in the combustion chamber. ■ The combustion flame is constricted by the nozzle, and the moment it exits into the atmosphere, it undergoes rapid gas expansion, becoming a high-temperature, supersonic jet. ■ The spraying material introduced into the combustion flame is melted and sprayed onto the substrate at supersonic speeds to form a coating. ■ The flame temperature is approximately 2400–2600K, which reduces the decomposition of WC. *For more details, please refer to the PDF document or feel free to contact us.

"SEP processing" is a surface treatment technology that involves immersing products in a special liquid to remove burrs and alter surface roughness. Since it only involves immersion in the liquid, it does not apply any physical external force, so even thin sheets do not experience deformation, dents, or distortion. Additionally, because it is a liquid treatment, it can be processed almost uniformly. It can polish even the interiors of extremely small holes where the liquid can penetrate. This technology enables the miniaturization of parts that were previously abandoned due to fine burrs and other issues. 【Features】 - No deformation, dents, or distortion even with thin sheets - Removes fine cracks and irregularities on the surface of parts, improving smoothness - Dimensional changes before and after processing can be managed in microns - Gaining attention as an alternative technology for precision cleaning (for the removal of contaminants and dust) - Since it only dissolves the surface of metals, the process change procedures are easy *For more details, please refer to the PDF document or feel free to contact us.

S.E.P processing is a new technology that allows for the clean removal of fine burrs and edges, which can change surface roughness and eliminate burrs, by immersing products in a special liquid. (Features) ● It can uniformly polish complex shapes (grooves, holes) that are difficult to finish with barrel finishing. ● There is almost no occurrence of deformation, distortion, or dents in thin workpieces. ● It removes fine cracks and irregularities on the surface of parts, smoothing them out, which reduces the coefficient of friction and improves the lifespan and durability of the parts. ● Due to improved surface roughness of metals, parts become less prone to rust. ● Dimensional changes before and after processing can be managed in micrometers. ● It does not affect the metal structure of the parts, so there is no concern about the occurrence of brittleness. (Materials that can be processed) Low carbon steel: SS, SPC, SPH, equivalent to S15C High carbon steel: SK, SKS, equivalent to S45C, SCM, SCR, SUJ SUS steel: SUS304, SUS316, SUS420, SUS630, etc. Tool steel: SKD, SKH Others: Copper and copper alloys, aluminum and aluminum alloys, nickel, cobalt, titanium, etc., general metals.
