1.Production Process

Huawei has the most advanced non-lap seam hot-press production process to process dam bags. The total pressure of the hot-press machines is 6,000 tons, which can ensure the rubber dam bags have no delaminating or turn spongy; can produce and mold non-lap seam rubber dam bags for dams under eight meters for one time. Rubber dam bags are flat and smooth; need no plain films during installation; can save labor and finance during installation and construction; ensure anchoring and no leakage and solve the slope rubber dam zonal force problem that cannot be solved before in China. The whole production process and automated production degree has reached the international advanced level.
