Suitable for Large Castings

Resin sand casting is suitable for medium and large metal components, especially parts with heavier weight, larger dimensions, and complex structures.

Strong Mold Stability

The resin-bonded sand mold provides good strength and stability, helping support complex shapes, thicker sections, and reliable casting production.

Machining Support Available

For parts requiring tighter tolerances or assembly surfaces, Jingong Casting can provide CNC machining, drilling, milling, turning, and inspection support after casting.

Advantages

Why Choose Resin Sand Casting

Resin sand casting is a practical casting process for producing medium and large industrial components with flexible size range, good mold strength, improved surface quality, and stable production control. It is widely used for machinery bases, pump bodies, valve bodies, gearbox housings, equipment frames, and heavy-duty cast parts.

Ideal for Medium & Large Parts

Resin sand casting is suitable for larger castings that require flexible molding, stable structure, and customized production according to engineering drawings.

Better Mold Strength

The resin-bonded sand mold offers higher strength and better rigidity than traditional green sand molds, helping maintain casting shape during pouring.

Good Surface Quality

Compared with conventional sand casting, resin sand casting can provide a cleaner casting surface and reduce excessive finishing work for many industrial parts.

Flexible for Custom Production

Resin sand casting is suitable for low-volume, medium-volume, and customized production, especially when parts vary in size, structure, or application requirements.

Quality Assurance

How We Ensure Resin Sand Casting Quality

Quality control for resin sand casting starts before production and continues through drawing review, pattern preparation, resin sand molding, core setting, melting, pouring, cleaning, machining, inspection, and packaging. Jingong Casting focuses on mold stability, material verification, dimensional control, defect prevention, and final inspection for reliable industrial castings.
01
Drawing & Casting Feasibility Review

We review drawings, 3D files, material requirements, part structure, casting weight, wall thickness, machining surfaces, tolerances, and application needs before confirming the production plan.

02
Pattern & Sand Molding Control

We check pattern accuracy, resin sand condition, mold strength, core requirements, gating design, riser layout, and mold assembly to support stable casting production.

03
Melting & Pouring Control

Material preparation, melting temperature, pouring timing, pouring stability, and batch consistency are controlled according to the casting material, wall thickness, and part structure.

04
Cleaning, Finishing & Machining

After casting, parts can be cleaned, shot blasted, ground, heat treated, drilled, milled, turned, or CNC machined according to drawing requirements and customer specifications.

05
Final Inspection & Packaging

Finished castings are checked for dimensions, surface condition, visible defects, machining quality, material requirements, inspection reports, and packaging protection before export delivery.
