TECHNOLOGICAL INNOVATION

In the production of Goodyear safety protective shoes, in addition to the special function of the bottom material structure, the company adopts the double suture method of stitching along the vamp, and then stitching with the middle sole. The whole piece of the middle sole is tightly bonded with the rubber sole, and then edging treatment is carried out. This manufacturing process makes the overall adhesion strength of the shoes more than double that of the ordinary cold bonded shoes.This manufacturing process makes the overall adhesion strength of the shoes more than double that of the ordinary cold bonded shoes.

In the production of Pu infusion safety protective shoes, the company directly infuses Pu middle sole into the mold for the upper, and then infuses Pu, TPU or TPR soles with different densities for the second time.This kind of production process of secondary infusing materials with different densities can not only increase the adhesion strength between the soles and the vamp (more than 50% higher than that of ordinary cold glued shoes), but also increase the comfort (double hardness) and meet various requirements Functional requirements (such as anti electric shock, anti-static, wear resistance, anti sliding, oil resistance, etc.).

MATERIAL INNOVATION

Using PC, ABS plastic wrap and glass fiber wrap instead of traditional steel wrap can reduce the weight of safety shoes by 20% and 35% respectively, and the mechanical strength remains unchanged, which can pass the European CE standard.

Kevlar insole, which is made of high-strength bulletproof fiber, is developed to replace the traditional puncture resistant insole. It can improve the problems of traditional steel core plate which is too hard to bend, uncomfortable and easy to puncture and expose, and can meet the European CE standard.

In addition to retaining the advantages of the original rubber characteristics and improving the bulky and hard uncomfortable feeling of the traditional rubber sole, it can effectively reduce the weight of the whole sole by 40-60%.
