SAND CASTING LINE
nO-BAKE RESIN SAND CASTING LINE
Resin sand casting line, also known as no-bake casting or self-hardening sand-casting technique is involves mixing reclaimed or fresh quartz sand with liquid synthetic furan resin and a catalyst, forming strong molds without heat.
With a typical resin content of 0.7%–1.1% and low free aldehyde levels (<0.3%), this process achieves high mold strength and superior casting quality, ensuring excellent dimensional accuracy, smooth surface finish, and minimal casting defects.
Resin sand casting is suitable for both small and large scale production, meeting international standards across multiple industries. Ideal applicate for producing complex parts in gray iron, ductile iron, carbon steel, and alloy steel, often combined with CNC machining for enhanced precision.
Feature:
1. Precision & Finish
Resin sand casting achieves high dimensional accuracy and smooth surface quality, reducing the need for extensive post-casting machining.
2. Design Flexibility
It produces complex geometries in both small and oversized parts, accommodating diverse metals like iron, steel, aluminum, and copper alloys.
3. Cost Efficiency
Low resin usage (0.8–2.0%), recyclable sand, and minimized waste significantly cut material expenses and production costs, especially for large batches.
4. Process Efficiency
Sand self-hardens at room temperature, requires no drying, and enables easy automation—reducing labor intensity and energy consumption.
5. Environmental Benefit
Generates less waste, allows efficient sand reclamation, and avoids harmful emissions, making it more eco-friendly than traditional casting.
