Our Process
Chemically Bonded Sand for Critical Work
No-bake sand molding uses a chemically bonded sand system — furan or phenolic urethane — that cures at room temperature without heat. The resulting mold is significantly harder and more dimensionally stable than green sand, making it the preferred process for nickel alloys, Monel, stainless steel, and demanding bronze work where surface finish and dimensional repeatability are critical.
At Ironbound, our no-bake department handles castings from small fittings through large valve bodies and structural components up to 6,000 lbs. All no-bake molds are made against customer drawings, with pattern dimensions verified before first pour.
Key Advantage
Superior surface finish and dimensional accuracy vs. green sand — the right choice for tight-tolerance or high-specification work
Advantages
Why No Bake?
Superior Dimensional Accuracy
Chemically bonded no-bake sand provides rigid molds that resist dimensional shift during pouring — ideal for tight-tolerance castings and complex geometry.
Excellent Surface Quality
Finer as-cast surface finish compared to green sand — reduces machining stock requirements and improves cosmetic appearance on critical external surfaces.
Complex Coring
No-bake process accommodates multiple sand cores for complex internal passages, water jackets, valve internals, and difficult-to-core configurations.
Large & Heavy Castings
The preferred process for castings from 50 lbs through 6,000 lbs — no-bake mold rigidity handles large pours without mold shift or blow.
