trolley

Molding method
1. Place glass on the mold on the Transport trolley andgradually heat the glass to near the softening
temperature in the heating furnace.
2. The glass reaching the softening temperature bends
along the mold.
3. Curved glass is cooled slowly in a slow-coolingfurnace to prevent distortion and warping.
* Temperature control in the furnace for heating andslow cooling is an important know-how and features.

Chemical tempering equipment replaces ions on the glass surface and strengthens the glass. Compared with air-cooledtempering, this equipment does not generate softening deformation, warpage, etc.
The temperature distribution in the chamber, which is important for strengthening, is made uniform by our proprietary
technology, and variations in stress values are reduced to a very small extent.

＜Features＞＜Delivery record＞･Equipment design that can accommodate various
sizes and lots according to customer requirements.
･Structure with minimal temperature difference in thechamber and very little unevenness in reinforcement.
･All processes are automated and can be managed by
one worker.

Equipment Composition
Our reinforcement equipment consists of a preheating
furnace, a treatment tank, a slow-cooling furnace, a hotwater tank, and a hot water tank.
Since automatic conveyance is used between eachprocess, labor is saved.

Chemicaltreatment tankAnnealing
furnace

Processing Method
1. Transfer the metal cassette containing the glass to the rack.
2. After preheating the rack in the preheating furnace,
immerse the rack in a potassium nitrate-filled treatment
tank (the immersion time depends on the required stressvalue and the depth of the compression layer).
3. Sodium on the glass surface and potassium in the liquid are
replaced, and a compressive stress layer is formed due to thedifference in diameter.
4. After completion of immersion, move to the slow coolingfurnace to prevent warping and slowly cool down to room
temperature.
5. After completion of cooling, move from the hot water
washing tank to the warm water washing tank and wash off
the potassium nitrate.

In the glass surface， Na+ is replaced by K+.
According to the ion diameter, the compressive stresslayer is formed.

Glass Processing Machines

GLASS HORIZONTAL BENDING & TEMPERING MACHINEThis is a roller-type glass bending device employing a unique press method and is suitable for glass bending with athickness of 4 mm or more.
They are mainly used in a wide range of applications, including construction (curved glass doors, windows, showcases,etc.), furniture, home appliances, and instrument covers.
Combined with a cold air reinforcement unit, it can be bent and then processed into tempered glass.

＜Features＞･Supports glass thickness of 4 mm to 12 mm.
･Can be formed into V-shaped orby using a specialpress in addition to a simple arc.
･Optional installation of air-cooled reinforcement unit

＜Example of bent glass＞･Glass heated in the heating furnace is quickly conveyed to thepress bending, strengthening, and cooling unit sections.
In the reinforcing unit section, the glass is bent to the specified
shape, and then rapidly cooled by air blown from the pipe toform a compression layer on the surface to strengthen it.
After being strengthened in the unit, glass conveyed by theconveyor is slowly cooled by the vertical cooling fan on theconveyor before being transported.

● Equipment Specifications･It is possible to produce bent glass of various shapes by aunique press method and a roller type heating furnace.
By using the optional air-cooled tempering unit, it ispossible to process the glass into tempered glass, which isabout 3 to 5 times stronger than ordinary float glass.
