Injection molding with Nichigo G-Polymer™
- By injection molding with Nichigo G-Polymer™, water soluble cast items can be produced.
- 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 controlling resin properties.

Lost Core and Outer Core Molding (Water Soluble)
Lost core and outer core made by Nichigo G-Polymer™ enable to produce one component product with complicated inside structure which needed to construct many parts.
