Vacuum die casting machine sizing hinges on four numbers — clamping force (kN), shot weight (g), vacuum level (mbar) and die envelope (mm). Mismatches between vacuum pump capacity and chamber volume cause porosity above 0.5 mbar residual pressure, the dominant defect in thin-wall aluminum and zinc s
A safety relay selection starts with three hard numbers — Safety Integrity Level target, output contact rating in amps, and the input-device compatibility (E-stop, light curtain, two-hand) — then narrows by channel architecture and terminal style.
Pillow block bearing sizing starts from shaft diameter (12-140 mm metric bore) and load case, then maps to insert series (UC204-UC218, UCP/UCF/UCFL/UCT 200/300) and housing material (cast iron, pressed steel, stainless, polymer). Misalignment ≤2°, dynamic load up to 62 kN per typical UCFC/UCP 200-se
Spec a plunger pump on four gates first — flow, pressure, fluid and duty — then pick brand. WOMA 700Z hits 1,500 bar at 435 l/min and 513 kW; Peroni PD covers crude/hydrocarbon service; HT400/TWS600S spares still flow through Jinan Baoshan.
