The Ichikawa Plant has a full set of facilities, including glass melting furnace, that can cover all processes from mixing glass raw materials, melting, molding, painting, inspection through to shipping in a consistent manner within the same factory.
We create product drawings and mold drawings based on design images from customers.
In addition to silica sand, which is the primary raw material, the plant reuses the cullets made by crushing bottles in the plant.
Control the temperature of raw material, melted at 1500 ℃, to 1300 to 1100℃.
Automatically weigh and cut the material to match the product.
Mold the melted glass in two steps, coarse mold and finishing mold.
Smooth the surface with a burner.
Cool bottles slowly from around 600 to 700 ℃ to ambient temperature.
Inspect bottles with various testers and automatically identify and reject defective bottles.
Inspectors individually check bottles whether bottles are made to the correct dimensions or the cap work properly.
A wide range of paintwork is applied on the surface of bottles to match the product.
Visually inspect for color inconsistency.
Products that passed the inspection are wrapped in cartons and shipped sequentially.
