1. Main machine frame is welded by high-quality profile steel plate and strong rectangular tubes , ensure a strong machine structure from the base .
2. Processed by heating-treatment to release the welding stress, the machine frames is with high strength, non-deformation, and with and high resistance to the expansive force from high-density products.
3. In order to keep the rust away ,the machine will be processed by shot blast treatment or sand treatment . Then it is painted by several times anti-rust bottom painting and several times of anti-rust surface painting , which will achieve very good anti-corrosion performance and make the whole block molding machine with a longer lifetime .
4. The surface of the mould is made of special aluminum alloy panel or stainless steel sheet which can realize a high efficiency of heat conduction, favorable tensile strength and long service life.
