i******f

Mech is designed using industrial-leading technologies. They are mainly CAD design, 2D & 3D printing, and Gait balance analysis tech, and so on.

h******z

Mech is inspected in various aspects. The pattern correction is checked based on size set garments measurement, the cut panels inspected before inputting to the sewing section, and fabric bonding strength checked after fusing.

q******f

A comprehensive consideration is involved in designing Mech . The correct choice of fabrics, seam technology, stitch workmanship, decision of dyestuff, and other elements are taken into account by professional designers.

s******w

The fabrics of Mech have been strictly inspected. They have been checked in terms of yarn defects such as thick and thin, fabric holes, fabrics shade matching, and fabric construction.

i******p

Mech has been strictly tested by third-party labs. It has been tested in terms of biomechanical comfort, stress distribution, slip resistance, tear strength, and cut resistance.

b******f

Adopting the cutting-edge water purification treatment technology in the industry, it can effectively filter out harmful substances such as bacterial microorganisms, colloids, suspended sediments, residual fluorine in tap water, etc., so that the water quality can meet the national water quality standards.
