  • Injection molded parts: principles and processes of injection molding

    The molding of injection molded parts relies on the collaborative cooperation of injection molding machines and molds. Injection molding, also known as injection molding, belongs to the mainstream molding process of thermoplastic plastics (thermosetting plastics can also be achieved through injection molding machines). The core is to melt plastic raw materials from solid to viscous state, fill them into the mold cavity through high pressure, and then cool and solidify to restore the shape of the mold cavity. The entire process can achieve automated continuous production

  • Key points for construction, installation, and use of polyethylene road substrate

    Ground cleaning: Remove sharp stones and weeds, level the ground (without hardening). Plate splicing: Align splicing according to the slot, reserve 2-3cm expansion joints (to cope with temperature changes). Edge fixation: Use sandbags or steel nails to fix the edge plates to prevent displacement
