metal die casting lubricants
● Type of product
DY05 (34#)is grey color with paste, strong adhesion, good heat resistance function, duration and suitable for processing z fine thin section,
● Product application
DY05 (34#)is grey color with paste, strong adhesion, good heat resistance function, duration and suitable for processing z fine thin section,too flat surface cast and spraying cap open system；
DY08(39#) is white color, fine particle, good heat resistance, strong adhesion and very good for base
DY07C(140#C) combines the feature between DY05 (34#)and DYO8 (39#) and uses it alone so as to obtain good effect and also
spreading cap open part to reach good function for making up shrinkage.
● Feature for product
1, Reducing cast stripping resistance to prevent it from adhesion and easy stripping
2. Improvement for cast surface quality and cleanness and brightness;
3. Metal liquid may flowing to facilitate cast frozen and cool metal speed
4. Protect mould type and cavity and reduce corrosion to extend it life
5, Feature for exhausting air function
● Storage for product
1.Keep it in cool place and better put at 10c-13'c and storage period is 6 months
2. Package for product 5 kg/bucket and 20 kg/box
● Instruction for use
1. DY05(34#)and DY08 (39#)stripping agent (coating) are two types of low case stripping (coating) to be combined to be use with best effect；
2. DY 07C (140#C) metal type casting stripping agent (agent) is one stripping agent (costing) made for casting motorcycle wheel hub.
Three coatings are used as follows for reference：
Requirement for operation
Mould must be treated for blasting sand before spraying coasting to remove rust,dirt substance and remaining costing on the mould surface The blasting sand uses manual sand sprayer and sand or glass Bead.
1.Before,mould is used, must stir it evenly(because long time place, it with heavy gravity is go down base）.
2.Before spraying, must clean old
coating on the mould
3. The mould temperature is lower than
170oc. It doesn't need spraying
4. don't spray too thick 0.07-0 2 mm
coating layer in normal
5. The pressure used in spraying
compressed air less than 30PSI and
spraying coating for mist
6. Spraying should be moved in different
7. The stripping agent is alkaline to
stimulate skin and certain metal to
avoid direct touch by hand. Don’t
splash on the skin and clothes. If it
happens like that, the skin and clothes
must be cleaned with clean water
rinsing. Put on protection glass when
Mould spraying temperature
Clean mould, pre-heating to 260℃ to 320℃, and then clean mould surface dirt substance, dust and adjust temperature to 210C to 250o and then for coating.
Compounding stripping agent
Stir stripping agent in the tank first and take out agent required to be stirred evenly up to the proportion of dilution, pass sieve( diameter 0. 55), put in the spray gun and should stir it evenly before use it.
Selection for spray gun
Adjust compressed air pressure(pressure not exceeding 30PSI) and spray jet first to make jet with mist. When spraying coasting, the jet keeps away from surface with 220 350 mm. If too far or near, it affects the quality for costing to cause spot or stack; When spraying coating, coating layer for 4-5 layers instead or 1-2 layers to obtain perfect coating. The operator should spray from different direction and move the gun continuously to reduce large area Coating Shade(Coating Lack） caused by bulge table cover strongly
Making up for cycle
Making up for spraying for each 4-5 hour with amount 1 -2 layers thin layer. In general, making up DY05 (34#) stripping agent and DY 07C (140#) stripping agent
continuing working 9 12 shifts shall need stop cleaning spraying sand in normal and spraying stripping agent again.
