The Vertical Molding Machine is a fully automatic molding system featuring vertical parting and double-face sand compaction (or air-precompaction + squeeze), engineered for high-volume, high-efficiency casting production. With the pattern mounted vertically and flasks closing from top to bottom, the mold cavity forms along the vertical axis—ideal for small-to-medium, complex-geometry castings with uniform wall thickness, such as engine blocks, brake discs, pipe fittings, and pump/valve housings in gray iron, ductile iron, or steel. Capable of 300–600 molds per hour, it serves as the cornerstone of modern green and smart foundries.
Working Principle
Sand Filling: Pre-metered sand drops into upper and lower flasks. Pre-Compaction (optional): High-pressure air flows through the sand for initial uniform distribution. Double-Sided Squeeze: Upper and lower rams apply synchronized pressure (80–150 bar) to form molds with high hardness (HB 90–95) and excellent repeatability. Pattern Withdrawal & Closing: The pattern strips vertically; the top flask flips 180° and aligns precisely with the bottom flask. Automatic Transfer: Closed molds are conveyed via roller tables or robots to the pouring station.
Key Advantages
High Throughput, Labor Savings Replaces 10–15 manual molders. Cycle time as fast as 6–10 seconds/mold, enabling annual output of 500,000–1,000,000 molds—dramatically reducing labor cost per casting.
Superior Mold Accuracy & Casting Consistency Vertical parting eliminates mold mismatch. Uniform compaction delivers dimensional accuracy to CT8–CT10 and surface roughness Ra ≤50 μm, minimizing fettling and scrap.
Saves Sand & Floor Space No runner waste in horizontal direction; optimized gating reduces sand consumption by 15–25%. Footprint is only 1/3 of horizontal lines—ideal for retrofitting existing foundries.
Fully Automatable & Industry 4.0 Ready Seamlessly integrates with auto-pouring, cooling, shot blasting, and robotic stacking. Equipped with MES/ERP interfaces for full-process data tracking and remote monitoring.
Eco-Friendly & Energy Efficient Enclosed operation minimizes dust emission (with dust extraction port). 30% lower energy consumption vs. jolt-squeeze machines—compliant with green foundry standards.
