Sintered Vents are unique venting plugs with a large number of straight, parallel and uniform pores.
These pores allow air or gas that gets trapped inside the mold cavity during the injection, or die casting process, to escape freely. The vents act like release windows, while keeping in the molten material from escaping. The objective to a good mold design is to specify as many strategically placed insertion points to hold the vents, thus reducing the possibility of manufacturing defective parts.
Advantage
1. High ventilation efficiency: porous ventilation rate is 5-13 times more than general exhaust plugs.
2. High casting productivity:Simple and easy to replace
3. Reduces Casting Defects: Drastic decrease of pin hole, misrun and gas run defects
4. Good durability: Reduce the frequency of replacement of exhaust plugs
5. Others: applicable to thin castings
Characteristic
1. The range of aperture is from 0.03-0.5m/m in diameter.
2. The air permeability varies according to the size and number of pores
3. The diameter and length of the hole can be customized according to customer requirements
