Municipal Manhole Covers (Core Applications): SMC/BMC resin manhole covers for municipal roads: round and square manhole covers (light- and heavy-duty), stormwater, sewage, and landscaping planters; composite grating products: cable trench covers, drainage ditch covers, septic tank covers, and fiberglass manure drainage grates; electrical meter boxes, junction boxes, and composite insulated enclosures Other Composite Molding Processes: By changing molds, the equipment can be used for the compression molding of various thermosetting composites, including fiberglass products, resin bases, and fiber-reinforced plastic components; it can also accommodate certain metal sheet stretching and profiling processes.

Machine Structure The machine features a three-beam, four-column monolithic structure made of welded steel plates that have undergone annealing to eliminate internal stresses, ensuring high overall rigidity and strong resistance to off-center loads. Copper alloy guide bushings ensure smooth slider operation and high parallelism accuracy, making the machine suitable for large-size manhole cover molds and supporting multi-cavity production with a single mold. Hydraulic System The machine employs an integrated hydraulic system with cartridge valves, resulting in minimal hydraulic shock, few leakage points, and reliable operation; The system has a rated pressure of 25 MPa, with stepless pressure adjustment; it supports both constant-pressure and constant-stroke molding modes, and the pressure-holding delay time is adjustable to meet the pressure-holding requirements for resin curing. Speed and Process Characteristics The fast-down, working-stroke pressing, and return speeds of the ram are adjustable in stages; the combination of rapid descent and slow pressure application is suitable for hot pressing of composite materials; Equipped with a lower ejection cylinder to facilitate demolding and removal of workpieces after molding. Electrical Control and Operation Independent electrical control cabinet with centralized push-button control, featuring three operating modes: jog adjustment, manual, and semi-automatic; capable of connecting to an external mold electric heating temperature control system, with mold temperature control ranging from 140–150°C, suitable for BMC/SMC hot-press curing processes; Optional configurations include touchscreen CNC, mold parameter memory, safety light curtains, and a movable worktable. Process Adaptability Advantages Large worktable surface accommodates oversized manhole cover molds, enabling the production of heavy-duty, high-load manhole covers. The machine supports integrated compression molding with built-in steel reinforcement frames, resulting in products with high density and stable mechanical properties, making it suitable for large-scale batch production.
