Lost-core and outer-core molding (Water soluble)
Nichigo G-Polymer™ can be used for lost-core and outer-core material.
Lost-core method is well known as producing curved and/or complicated tube structure plastic and set it melt and dissolve.
It is possible to produce lost-core by Nichigo G-Polymer™, using ordinary injection molding and removal of lost-core can be easily done by warm water (cold water). So workers on site and machines are also in good circumstances because of no solvent.
Further, it is possible to adjust solubility speed, resin strength, flowability, flexibility and softening temperature by controling resin properties.
Hollow lost-core
It is possible to make hollow lost-core molding since it can be adhere by water. (Make stand beam inside or fill sand or small beads in case if more strength is necessary)
【Advantage of hollow lost-core】
・ Decrease the usage of lost-core resin
・ Reduce
removal time of lost-core
・ Decrease waste water
