U型槽模具的成型采用注塑方法加工而成，钣金钢颗粒经过高温溶解成液体注入U型槽水泥制品铁模具中，待冷却后将铁模具拆掉，U型槽模具便成型。U型槽模具采用3-8毫米的钣金钢经过剪裁，弯折，造型，压圆，焊接，切割，拼装，打磨，喷漆等多道手续加工得来。路牙砖的产生是经过U型槽模具的加工得来的，将搅拌好的混凝土，注入路沿石钢模具中，经震动平台震动成型后，放在背光的地方自然养护即可。

U type groove die molding by injection molding method of processing, sheet steel after high temperature particles dissolved into the liquid injection type U groove cement products iron mould, after cooling the iron mold removed, U groove forming mould. U groove 3-8 mm steel plate die by cutting, bending, welding, molding, rotary, cutting, grinding, assembly, painting and other procedures to multi-channel processing. The production of road brick is processed by U groove mold, and the well mixed concrete is injected into the stone steel mould, and then vibrate through the shaking platform, then it is placed in the natural place of backlight.
