1. Venting in permanent mold casting
|
|
Sintered Vent with 0.3 or 0.5mm pore diameter has been widely used for venting system in permanent mold casting of aluminum alloys.
Venting efficiency increases significatly.
With its porosity rate 4-30 times higher than conventional vents', small Sintered Vent can do the big job.
Productivity is improved highly.
Fast and easy exchange of vents and easy cleaning of molding dies improve productivity of casting.
Vents of 0.5mm pore diameter for smaller ones are available as the standards.
Sintered Vent assures the sound castings which are free from the "misruns" and the "cold shuts".
The major automakers all over the world have been using Sintered Vents.
2. Venting in injection molding
|
|
Sintered Vent with very fine pores has been successfully used for venting system in plastic molding..
Isolated and straight pores, 0.05 mm in diameter, are large enough to allow the escape of air and volatiles, and are small enough to prevent the passage of plastic melt
* The location of weld line can be adjusted easily.
* Shorten shot cycle and increase the productivity.
Venting in blow molding of plastic container
|
|
Sintered Vent with 0.3-0.5mm pore diameter is also being used for venting system in blow molding of plastic container
Sintered Vent specification
|
|
* Gravity and Low pressure Die-casting (Pore die. 0.5mm)
* Low Pressure Die-casting (Pore dia. 0.3mm)
* Injection Molding and Die Casting (With Pore diameter 0.2~0.03mm)
