The producing process of the flexible graphite sheet.

1. A brief introduction of the whole production line.

   We use this production line(as the following photos present) to produce the flexible graphite sheet. 

This production line adopts international advanced technologies, 

making us produce high quality flexible graphite sheet and

 having become a powerful tool for us to meet the different requirements of our customers.

2. The raw material-expandable graphite

   The expandable graphite comes from good mine and mineral resources, 

making sure the superior quality of the expandable graphite

 and a good start of the production from the beginning.

3. The mixing process.

   In this process, the expandable graphite is poured into the mixer to be well mixed. 

And after the mixing, they go into the hopper.

4. The expansion process.

   After mixing, the expandable graphite goes into the expansion stove to be high temperature expanded.

 The S, chlorine and many other chemical elements are get rid of from the expandable graphite

 in the expansion stove.

5. The transportation of the having been expanded graphite.

   In this process, the graphite is transported by the draught fan from the expansion stove

 to the material pool.

6. The preliminary roll-forming of the flexible graphite sheet.

   After passing through the material pool, the flexible graphite sheet is preliminary formed.

7. The adjusting process of the density and thickness of the flexible graphite sheet.

   There are many groups of rolls in the production line. 

Through these rolls, the adjusting of the density and thickness is fulfilled.

Productperformance:

Each roll of flexible graphite sheet is packaged with five-corrugated paper case firstly,

then these paper cases would be packaged in one big wooden case.

Or, we make the package according to your request.

About the sample.

Usually, the sample is free.

If the quantity of the sample is big, the sample has to be charged.

The cost of the sample and the transportation is negotiable based on the details.

About the production capacity.

We can produce 1000 M.T. of flexible graphite sheet and 500 M.T. of reinforced graphite sheet per year.

 Q: What’s the highest temperature your flexible graphite sheet can stand?

A:  Maximum 800 degree centigrade.

Q: What about the thermal conductivity of the flexible graphite sheet?

A:   We do not have the data about the thermal conductivity at present.

Q: In order to get a quotation of flexible graphite sheet, what information should I

               provide?

Q: What about the lead time?

A: It depends on the quantity you need.

Q: Do you have discount?

A: Different quantities will have different discount ranges.

Q: What about the payment terms?

A: We accept T/T, L/C, D/A, D/P, waimaotong.com’s Escrow Service, Paypal, Western Union,

   MoneyGram.
