2. Mounted hanging:

2.1 preparationsbefore mounted hanging.

2.1.1 Check theconductive partslike conductive beams and bars. They should be regularly polished, cleaned or repaired.

2.1.2 Get ready conductivity of aluminum and aluminum wire.

2.1.3 Check the pneumatic tools and related equipment.

2.1.4Check whetheror not requirements likelength, count, color, thicknesson the flow paper or production task list are consistent with the order drawingand actual materials.

2.1.5Depending on the specifications (size of circumscribed circle, external surface area, etc.) to determine the count and space. To control the pigment spacingabout 1.2 times thanthe horizontal width of the material shaped,and the white materialspacingabout 1 time than the width.

2.1.6Choose the appropriate rack, and ensurethat hooknumber of negative and positive hangersis the same with the count of materials shaped.

2.2 Mounted hanging:

2.2.1 When hanging, fix the topside one first, and then the bottom one, and then arrangethe remaining sections in the middle, and tighten the screws.

2.2.2Before hanging, placing one aluminum sheet between the materialand aluminum screw p so that it can prevent poor conductivity impactingoxidation, coloringand electrophoresis.

2.2.3 When hanging, itis not allowed to hang all the materials in the lower or upper rack.

2.2.4 The hanged materials shouldrecline more than 14 degrees in order to facilitate air exhausting in electrophoresis or coloring,and reduce the air bubbles.

2.2.5When hanging,considering the facingof the decorative surface and groove to prevent the color shading, bubbles, pitting appearing in the decorative surface.

2.2.6Like someflexible and easily deformedmaterials, put one more rack or aluminum wire in the middle to prevent friction between the materials or touching tank plate, and that may abrade or burnthe surface.

2.2.7 When selectingvice-bar rack, the plug rod is preferred. When using aluminum banding, they must be evenly spaced, and the outcrops should be less than 25mm.

2.2.8Materials with great disparityof cross-section size andshape are prohibited to hang in the same row.

2.2.9When hanging and handling equipment, you must wear clean gloves,gently andwell
