.... No-bake molds usually are not 100% cured even at the stage of casting. Self-setting systems can be used with different types of organic resins and inorganic binders, as described subsequently ( Ref 11 , 23 ). Furan No-Bake Systems Furan no-bake systems were first introduced to automotive foundries...

The measured average composition and mixture molecular weight of the gas evolved within 2 min after pouring metal into phenolic urethane cold box (PUCB) and phenolic urethane no-bake (PUNB) bonded sand molds, as shown in Table 1 . The results in Table 1 show that the binder gas generated during pouring...

.... The process, known today as lost-foam casting (using loose, unbonded sand), is patented a short time later. Phenolic and furan acid-catalyzed no-bake binder systems are introduced. Ductile iron desulfurization via shaking ladles is developed in Sweden. 1959—General Electric uses the transient heat-transfer...

Thermoplastic materials can be thermal cycled a limited number of times without undergoing irreversible chemical changes. At elevated temperatures, thermoplastics soften and can be molded or extruded into shape...
