1.Plastic mold is adopted wear-resistant and heat-resistant silicone, aluminium film temperature is 200 °C. 2.After shaped, lined with bonding tightlerlly, Not occur wrinkle, no deformation, no bubbles, may reduce breakage. 3.Samples can be shaped and modelled in time, reduce development time, reduce the cost. 4.It makes for upper operation easier to shape vamp accurately , increase output.
