상기 성형단계에서는 알루미늄 강재를 고온으로 가열한 상태에서 고온의 금형으로 통과시켜 몸체를 만든다. 즉 고온상태로 가열한 알루미늄 강재를 압출시켜 일정한 몸체로 성형시키게 된다.In the forming step, the aluminum steel is heated to a high temperature to pass through a high temperature mold to make a body. In other words, the aluminum steel heated to a high temperature state is extruded to form a constant body.

상기 밴딩단계에서는 성형된 몸체의 선단부를 각각 일정한 반경으로 굽힘가공한다. 여기서, 몸체는 선단부가 앞쪽에서 뒤쪽으로 40∼150R 정도로 굽힘가공하는 것이 바람직하다.In the bending step, each of the ends of the molded body is bent to a predetermined radius. Here, the front end portion is preferably bent about 40 to 150R from the front to the rear.

상기 절삭단계에서는 밴딩된 몸체의 선단부 내측면을 각각 평면으로 절삭가공한다. 여기서, 밴딩된 몸체의 선단부를 밀링으로써 절삭하여 몸체와 평행하게 평면이 되도록 가공한다.In the cutting step, the inner surface of the tip portion of the bent body is cut in a plane. Here, the front end of the bent body is cut by milling and processed to be parallel to the body.

상기 연마단계에서는 메시가 300∼400 정도인 사포를 사용하여 몸체의 전체를 마름질 한 후, 연마재를 뿌리고 연마기를 통해서 몸체의 표면을 연마한다. 여기서, 연마단계는 표면처리할 때 굴곡면을 없애기 위하여 몸체의 표면전체를 연마가공하는 것이다.In the polishing step, the entire body of the body is dried using sandpaper having a mesh of about 300 to 400, and then the abrasive is sprayed and the surface of the body is polished through a polishing machine. Here, the polishing step is to polish the entire surface of the body to remove the curved surface when the surface treatment.

상기 표면처리단계에서는 몸체를 에노다이징처리하여 표면에 단색 또는 다색으로 색상을 넣게 된다. 진행과정은 우선 수산화소다 10％와 계면활성제 0.5％를 섞은 물을 60∼80℃로 데워서 몸체를 담근 후 표면을 닦고, 가성소다에 약 10분정도 담근 후, 증류수에 세척한다. 그 후, 몸체를 양극에 걸고 10∼20％의 황산용액에 20∼40분정도 담근다. 그 후, 몸체를 증류수에 세척하고 중화제에 5분간 담근 후 재차 따뜻한 증류수로 세척한다. 그 후, 몸체를 염색조에서 일정시간 동안 담궈서 색상을 넣는다. 여기서, 염료는 알카리성 염료, 산성염료, 산성매염 염료를 사용할 수 있고, 단색 또는 그라데이션으로 색상을 넣을 수 있다. 몸체에 색상을 넣은 후, 80∼90℃로 끓는 증류수에 30분 가량 봉공처리한다. 그 후, 몸체의 표면에 왁스처리하여 부식을 막고 색상의 선명도를 높이게 된다.In the surface treatment step, the body is anodized to put a color in a single color or multicolor on the surface. The process is first warmed with water mixed with 10% sodium hydroxide and 0.5% surfactant to 60 ~ 80 ℃, soak the body, then wipe the surface, soak in caustic soda for about 10 minutes, then washed in distilled water. Thereafter, the body is hanged on the positive electrode and soaked in 10-20% sulfuric acid solution for 20-40 minutes. After that, the body is washed in distilled water, soaked in neutralizing agent for 5 minutes and washed again with warm distilled water. After that, the body is immersed in the dye bath for a certain time to add color. Here, the dye may be an alkaline dye, an acid dye, an acid mordant dye, and may be colored in a single color or gradation. After adding color to the body, seal for 30 minutes in distilled water boiling at 80 ~ 90 ℃. Thereafter, the surface of the body is waxed to prevent corrosion and to increase the vividness of the color.

이와 같은 방법으로 핸드레일 제조할 경우, 핸드레일 표면에 다양한 색상을 넣을 수 있으며 표면이 부식되지 않고 색상이 오랫동안 보존될 수 있게 된다.When the handrail is manufactured in this manner, various colors can be put on the surface of the handrail, and the surface is not corroded and the color can be preserved for a long time.
