Product Description

Resin Sand Casting (also known as resin-bonded sand casting)

Resin Sand Casting (also known as resin-bonded sand casting) is an advanced sand casting process that uses resin as a binder to bond silica sand or other refractory sands, forming high-strength, high-permeability sand molds and cores. Our Resin Sand Casting Equipment integrates mixing, molding, core making, pouring, shakeout, and sand reclamation into a complete production line, realizing efficient and standardized casting production. The equipment is compatible with two mainstream processes: self-hardening resin sand (the most widely used, hardening at room temperature without heating) and hot-hardening resin sand (suitable for complex cores, requiring heating to 120~180℃ for hardening). It is suitable for casting gray iron, ductile iron, carbon steel, alloy steel, stainless steel, aluminum alloy, copper alloy, and other materials, capable of producing both small-batch precision parts and large-scale heavy castings.

Core Components & Working Flow

Resin Sand Mixer:Mixes silica sand, resin, curing agent and other materials in precise proportions to form moldable resin sand with good fluidity and adhesion.

Molding Machine:Uses the mixed resin sand to shape molds according to the product's 3D model, ensuring mold accuracy and surface finish through mechanical compaction or vibration.

Core Making Equipment:Produces complex internal cores (e.g., for engine cylinders) that match the mold, using cold-box or hot-box processes to accelerate resin curing.

Pouring System:Transports molten metal (steel, iron, aluminum alloy, etc.) into the assembled mold-core combination, with temperature control and flow regulation functions to avoid casting defects.

Sand Regeneration Unit:Recovers and treats used sand by removing resin residues, cooling and screening, realizing over 90% sand reuse to reduce costs and environmental impact.

Waste Treatment Module:Collects and processes waste gas, dust and wastewater generated during production, complying with environmental protection standards.

Key Advantages

High casting precision:Resin sand mold has strong stability and low collapsibility, reducing dimensional errors and surface defects of castings.

Efficient production:Automated operation shortens the molding and curing cycle, improving production efficiency by 30%-50% compared with traditional sand casting.

Wide applicability:Suitable for small-batch and mass production of castings with complex structures, thick or thin walls, and various material types.

Environmental friendliness:Sand regeneration technology and waste treatment system minimize resource waste and environmental pollution.

FAQ

Question about Resin (No-bake) sand production line

Q1:What are the main functions of the resin sand reclamation line?

A:This production line automatically recycles, purifies and reclaims waste resin sand after casting. It effectively solves the problems of sand waste, solid waste accumulation and high cost of new sand purchase. The reclaimed sand can be reused directly for molding, greatly reducing production costs and meeting environmental protection standards.

Q2: What is the recycling rate of reclaimed resin sand?

A:The reclamation process is stable and reliable, with a sand recycling rate of over 90%. Dust and residual resin film are completely removed. The performance of reclaimed sand is close to new sand, which can replace more than 90% of new sand for molding, saving long-term raw material costs.

Q3:Is the production line space-saving? Can it adapt to existing workshops?

A:Adopting modular and compact design, the whole line can be customized according to workshop size, site layout and capacity requirements. It is suitable for both new workshops and old factory renovations with convenient installation and commissioning.

Q4:What is the automation level? Does it require many workers?

A:The whole line adopts centralized intelligent control, realizing full automatic operation from shakeout, conveying, crushing, reclamation, sand storage to sand mixing. Only 1-2 workers are required for supervision, which greatly saves labor cost with stable performance and low failure rate.

Q5:Is the equipment environmentally compliant? How to control dust?

A:Fully enclosed operation with pulse dust removal system ensures thorough dust collection without overflow. It fully meets domestic environmental inspection standards and export environmental requirements, supporting green and compliant production.

Q6:Is customized production line available?

A:Customized solutions are available according to customer hourly output, casting types and used sand conditions. We provide small, medium and large complete resin sand processing lines, as well as customized sand mixing, conveying and storage systems to support one-stop foundry sand treatment solutions.
