This article will explain to you three parts: equipment appearance, component materials, and finished product inspection, to help you choose a value-for-money machine.

1. Appearance

Professional manufacturers will conduct relatively neat and beautiful appearance design on the basis of the stability and stability of the equipment in the design and assembly of equipment. equipment

The frame and the whole are horizontal and vertical, without excess bending deformation, firm in welding, smooth and smooth, without welding defects such as virtual welding and splashing. If the appearance of the fuselage machine

The base of the rack has obvious wear and tear caused by shaking, which proves that their fuselage racks are not handled well enough in the micro-debugging operation.

2. Material of parts

The roller is used in the cold rolling of the color steel roofing roll forming machine, and the material requirements are relatively strict and precise. From the operation of the roller, check whether each plate is gradually deformed during the molding process. On the roller material, hard chrome plating, mirror polishing and heat treatment are required after finishing. In appearance, the plating is bright, no color difference, no indentation and scratches, and no rust.

3. Finished product inspection

The surface of the board is flat, no obvious indentation at the non-break point, no obvious bag wave, no burr, no crow’s feet, no scratch paint, no obvious color difference, no wave

On the wave side, the 6-meter-long head ≤±2cm, the width error range ±2cm, the height error ≤±1cm, the length error 6m≤1cm, and the diagonal error ≤1cm.
