Molding method example
| Molding machine | A liquid injection molding machine or an injection molding machine with an injection unit compatible with liquid materials is required. |
|---|---|
| Handling |
Since it is a solvent-free, one-component type, it is easy to handle at the molding site. Since curing failure occurs in the presence of air, it is necessary to reduce the pressure inside the mold during molding. |
|
low filling pressure Low material loss |
Since it is a low viscosity liquid, the filling pressure during molding can be lowered. Therefore, when performing insert molding, the load on the insert can be greatly reduced. Since the runner and sprue can be made thinner, it is expected to reduce material loss. |
| Product shape | Because it is a low viscosity material, it can be injected into various shapes and places with little clearance. |
