Product Description

This tempering furnace is a combined type. It is specially designed for the customer who don't have big demand for production, and want to save the machine cost. This glass tempering furnace could make both sidelite single curved tempered glass and backlite curved tempered glass.
This glass tempering furnace is used to produce the tempered glass for Automotive Backlite & Sidelite. It is combination type, there is single curvature bent section and multiple curvature bent section in this machine. The single curvature bending no need mould, but the multiple curvature bending need mould.
This furnace is used for the customers who mainly provide the glass for aftermarket. There are many glass type, but the order demand is not big. With this combination, it could reduce the space and cost greatly.

About force convection system
Q.Why should i buy a glass tempering furnace with force convection system?
A.Yes, we suggest you to choose a force convection type furnace, this furnace could temper soft Low-e glass, because now, the Low-e glass is more and more popular in the market. And this force convection system can not be added in future. So from the beginning, we suggest the customer to buy a tempering furnace with force convection system.
 
Q.Do we need to buy a tempering furnace with top and bottom force convection system?
A.If the furnace with top and bottom force convection system, we call it "full convection tempering furnace". but we don't suggest you to buy the full convection furnace. This technology is a old technology which is popular few years before, during that period, many famous tempering furnace factory, such as North glass, Land glass, Jingglass, use this technology, but after running for some years, there are many problem for the bottom convection system, for example, the convection fan's shape changed, broken glass fall down to the heaters, etc.
Now, more and more factory asked our engineers to modify their full convection to top convection only.
 
Q.So only the top convection system is enough for tempering Low-e glass?
A.Yes, it is enough. You know, there are ceramic rollers at the bottom oven, there are enough heat by radiation from the ceramic roller.
 
Q.Which convection system is better? SS tubes or ceramic tubes?
A. SS convection tubes are better, but its cost is higher than ceramic tubes. For ceramic tubes, it is easy broken or after some time, if the steel pipe shape changed, the ceramic tubes will fall down. And it is not easy to repair to to re-fit the structure. So we suggest you to buy a force convection system with SS tubes.
 
Q.Does all the tempering furnace could have force convection system?
A. Yes. But now, the Low-e glass is mainly for architecture, buildings, and most of them is flat tempered glass. So now, on the market, there is no need the force convection glass tempering furnace for automotive glass, furniture glass.

About two heating chamber furnace
Q.: When will should i buy a glass tempering furnace with two heating chambers?
A. If you have many orders, but one set of glass tempering furnace could not meet the order demand. And you don't have space or extra investment to buy another separate glass tempering furnace. If you want to improve the quality of tempered glass.
Q.: Do these two heating chamber has force convection system?
A. Yes, if the investment is ok, we suggest you to make both two heating chamber with force convection system. This is very good to produce the triple silver Low-E glass. Now, in the market, there are more than 60% two-heating chamber furnace has 2 force convection system. If you don't have triple silver coated glass, you also could choose one heating chamber has force convection system, this could temper double silver coated glass.
