What is the phenomenon of tensile testing machine is not normal

Users in the purchase of tensile testing machine not only to select the manufacturers, the equipment also have to observe clearly, it is best to try it is normal, if the following 10 kinds of conditions are not normal, it is best not to worry about the purchase, choose more than a few comparison Oh.

1. The color of the paint is unpleasant, the hue and the chromatism are inconsistent, and the boundaries of different colors are not clear and pollute each other.

2, paint and putty does not have enough strength, can not resist the oil and corrosion resistance, there is a peeling phenomenon.

3. The unfinished surface of all parts and accessories is not primed. Rust, sand, oil, and other contaminants have not been carefully removed prior to priming. Painted surfaces are incomplete, unsmooth, uneven, and inconsistent in color, with spots, wrinkles, bubbles, and adherents.

4, the surface of the electroplated parts have spots, uneven coating, peeling phenomenon.

5. The surface shade of blackened parts is uneven, with spots, rust, etc.

6, the various signs on the device are not clear. Signage is not fixed in a prominent position. The fixed position of the sign is incorrect, uneven, insecure, and skewed.

7, the appearance of the surface of the pattern does not specify the convex, concave, rough and other damage.

8. There is a clear misalignment on the edge of the component joint surface. Inconvenient loading and unloading of doors and lids

9. The countersunk screw protrudes from the outer surface of the part, and there is a clear eccentricity between the head and the counterbore.

10. The machined surface of the instrument part has rust, burrs, bumps, scratches and other defects.

Whether you are selecting a tensile testing machine or other equipment, if you have encountered some of the above problems, you must compare a few more and pay attention to observation before you can buy more suitable and practical equipment.
