DIEDRESS - 1400
(Boron Nitride base coating For GDC & LPDC)
Product
Diedress – 1400 is specially designed coating. Unique property of coating gives excellent release and hence better life of diecoat.
Function
In GDC and LPDC, castings are produced with larger / thinner sectioned aluminium alloys. When hot metal (aluminum alloy at 720ºC) is cast into die (at 250ºC) the rate of heat extraction from the metal will be high and as a consequence fluidity of the cast metal will be reduced.
Correct use of an insulating coating can control the rate of heat extraction in various parts of the die and so retain fluidity as well as provides a desirable directional solidification pattern in the casting.
Instruction
Application
Dilute the coating with soft water in the ratio 1:3-5 (Product : Water) mix uniformly and apply coating by spraying. The application of the coating is varies from very thin, where maximum chilling is required and thick on runners, feeders, thin cast sections, etc.
Spray the diluted coating on to the die and core faces using a good atomizing gun. The die temperature should be between 180 to 220ºC so that the spray hits and dries quickly without running. Then re-heat the die to normal working temperature before casting metal.
