JIAHE offers different types of mould.There are "One Time Ceramic Mould" and "Graphite Mould" with different shapes of mould to suit of mould to suit for different welding works.

One Time Ceramic Mould is made of ceramic suitable for "One off" welding work.

Graphite mould is made of high quality graphite suitable for high quality welding work and can be used for several times.Which has following advantages.

1. A smooth metal connection that will not loosen or corrode.
2. It is not affected by high current surge or over current.
3. No need for the external welding machine.
4. use only lightweight and cheap equipment.When making a copper wire connection of Ground rod or other metal connection,place the FLUX powder into the graphite mould or one time ceramic mould. Just ignite to start the welding process. The result will be clean and smooth connection surface,Which has been ficld proven. It is also application for other metal such as: Iron, Steel, Railway track, Wrought and cast iron, Bronze, Nichrome and Brass
JIAHE can be used in various application to have the certainly good connections in work. Many projects trust in JIAHE Such as:

- Lighting and Surge Protection
- Grounding in Electrical Work
- Railway Construction
- Cathodic Protection
- Another High Capacity of Current Supply

The JIAHE connection mould is designed to last for an average of **0 connections. This will vary according to the care given the mould during use.
Exothermic Welding Powder: qualified by national authority test department-"WHVRI" with the Inspection report, only in China.

Exothermic Welding Powder:
The capacity of an earthing circuit to protect the safety of personnel depends on the quality of the connections made .
JIAHE exothermic welding is RENTONG ' s patent product in China . And it has the best quality in China as the same product in U.S.A. and U.K . So JIAHE Exothermic welding powder is qualified by national authority test department Wuhan High Pressure Research Institute State Power Corporation of China with the testing reports . JIAHE is the only one who obtains this testing report at the present time .
The principle of the exothermic welding consists of bring together a welding filler material and ignition agent in a suitable graphite mould. The shape of the mould, its dimensions , and the size of the weldmetal , are all dependent on the item to be welded and their size .

The Exothermic Welded Connections are made using the high temperature reaction of powdered copper oxide and aluminium. The process is a simple, self-contained method of forming high quality electrical connections which requires no external power or heat source.
 Exothermic Welded technics reaction equation is as follows:
