How to Recognize Neodymium Iron Boron Appearance Defects Correctly

NdFeB appearance defect detection of a correct understanding, is conducive to customer an objective understanding of this new detection technology. Equipment is not a panacea, but no equipment entirely rely on manual testing is a great risk, the long run, machine substitutions is an inevitable trend.

Can detect five major categories of appearance defects

Appearance defects are produced in the production of NdFeB links, for example, the product cracks in the sintering process occurs, knock edge, scratches in the slices or logistics link, while the trachoma and pits in the electroplating occurs. According to the causes of defects and forms of performance, at present, HSMAG equipment can detect five categories of appearance defects:

A, cracks (including cracks, cracking, etc.)
B, knock the edge (including Kepian, collapse edge, material residue)
C, pitting (including pitting, linen, bubbles, scars, slag layer, local too thick, electroplating tumor)
D, trachoma (including trachoma, pores, pinholes, particles, etc.)
E, scratches (including scratches, line marks, knife marks, etc.)

Is it easy for customers to do this? Software is the soul of a device, equipment operation is easy to understand, is critical. Is like smart phones, customer experience is critical. HSMAG NdFeB equipment, the “crack”, “scratch”, “trachoma,” these three categories of appearance defects detection, the operator just finger touch screen adjustment, sliding around “loose – strict” frame, that can be set easily. HSMAG engineers can also assist customers through 3G, and use APN technology to prevent network attacks.

Slide your hand to adjust the appearance of the interface compared to other similar detection interface – the interface set up too many projects, complicated logical relationship, so that workers and even engineers are difficult to understand. HSMAG testing equipment in the operating experience, superior.

Rational knowledge of the equipment

A, detection speed is not the sooner the better? HSMAG NdFeB equipment efficiency can reach 200-300 tablets / min, leading the detection efficiency of similar equipment. But some customers still feel that is not enough, but also hope to speed up. In fact, not the faster the better, more than the limit speed easy to miss measurement (such as cars: more than the limit speed, it is prone to accidents). Equipment, detection speed and quality of detection have an optimal balance, not unilateral pursuit of fast.

B, all the appearance of defects can be detected? At present, not all defects can be detected. If a device company to tell the user all the appearance of their equipment defects can be detected, it is not true. Such as stains, shallow knife marks detection, equipment testing than people (deep knife marks equipment can be detected). Equipment imaging is black and white instead of color, black and white images for fast processing, so the stain detection results are not ideal; there shallow knife marks, the human eye can be three-dimensional inspection, detection rate higher than the equipment. When a batch of products in the shallow knife marks and stain more, the proposed re-examination of the man.
