Products classified under HTS 8474.80.00.20
Vibro-Compaction Sand Mold Forming Machine
This machine uses vibration and compaction to form precision sand molds for metal casting in foundries. It processes sand mixed with binders into rigid molds by applying controlled vibrations and pressure. Classified under HTS 8474.80.0020 as it specifically forms foundry molds of sand.
Automatic Green Sand Molding Line
An automated production line that forms green sand molds (moist sand with clay binder) for high-volume foundry casting. It includes pattern drawing, sand filling, and compaction stations to create mold cavities. Falls under HTS 8474.80.0020 due to its dedicated function in forming foundry sand molds.
No-Bake Sand Core Shooter Machine
This machine shoots no-bake sand (chemically bonded) into core boxes to form foundry cores used in metal casting molds. It precisely deposits and compacts sand for complex internal mold features. HTS 8474.80.0020 applies as it forms essential sand components for foundry molds.
Horizontal Flaskless Matchplate Molding Machine
Advanced machine that forms sand molds without traditional flasks using matchplates for pattern matching. Produces cope and drag molds simultaneously through high-pressure sand compaction. Specifically classified in HTS 8474.80.0020 for sand foundry mold formation.
Disamatic Vertical Green Sand Molding Machine
High-speed vertical molding machine (Disamatic type) that automatically forms complete green sand molds for iron foundries. Uses pattern plates and squeeze compaction for production rates exceeding 500 molds/hour. HTS 8474.80.0020 covers this dedicated foundry sand mold forming equipment.
Sand Mixer-Molder Combination Unit
Integrated unit that mixes foundry sand with binders then immediately forms molds in sequence. Provides consistent sand quality directly into molding station for optimal mold integrity. Classifies under HTS 8474.80.0020 when forming function predominates over mixing.
Cold Box Core Making Machine
Specialized equipment for producing sand cores using cold-box process (amine gas catalyst) for complex foundry molds. Blows sand into heated core boxes then gasses for instant curing. HTS 8474.80.0020 includes core-making as integral to sand foundry mold formation.
Fully Automatic Flask Molding Machine
Complete automation system handling flask placement, sand filling, compaction, pattern draw, and mold closing. Produces ready-to-pour sand molds for serial foundry production. Precisely matches HTS 8474.80.0020 description for sand foundry mold forming machines.
