The green sand molding machine is a core subdivided type of clay sand molding machine, and the two have an “inclusion relationship”. The key differences focus on sand state and process adaptability.
I. Scope and Inclusion Relationship
Clay sand molding machine: A general term for molding equipment using clay (mainly bentonite) as the sand binder, covering two core sand processes: wet state and dry state (used after drying).
Green sand molding machine: Specifically refers to equipment using “wet clay sand” — a mixture of clay, sand and water, used directly for molding without drying. It is the most widely used type among clay sand molding machines.
II. Specific Difference Comparison
1. Different Sand States
Clay sand molding machine: Compatible with both wet sand and dry sand. Dry sand requires drying and curing, while wet sand is used directly.
Green sand molding machine: Only compatible with wet clay sand. The sand contains a certain amount of moisture and no drying step is needed.
2. Different Process Characteristics
Clay sand molding machine (dry sand process): High sand strength and good precision, but complex process, high energy consumption and long production cycle.
Green sand molding machine: Simple process, high efficiency and low cost, but lower sand strength, prone to defects such as sand adhesion and blowholes.
3. Different Application Scenarios
Clay sand molding machine (dry sand): Suitable for large, complex and high-precision castings (e.g., machine tool beds, heavy machinery parts).
Green sand molding machine: Suitable for small and medium-batch, small and medium-sized castings (e.g., auto parts, agricultural machinery accessories). It is currently the most commonly used molding equipment.
III. Core Summary
Essentially, the two have a “general category and subdivision” relationship. The clay sand molding machine has a wider scope, and the wet sand molding machine is its most commonly used branch. In practical selection, the core factors are casting size, precision requirements and production efficiency needs.
