Sintered Vents

Sintered Vent is produced by applying sintering process of powder metals and has many paralleled, straight micro pores that allow air/gas purge.
It is also called air vent or gas vent and used as gas purging vent during aluminum casting and resin molding. If a certain level of air and/or gas, which comes from raw materials, remains inside the cavity at the time of injection of melted resin or casting of aluminum alloy under low pressure, it defects the finished products. Our vent helps purging those air and gas during molding process.

Characteristics of Sintered Vent
Contains micro pores of 0.02mm to 0.5mm
300 to thousands of straight micro pore per 1cm2
Various combinations of pore diameter and numbers of pore
Better thermal conducivity due to copper infiltration method
Steam treatment for rusting prevention

Application of Sintered Vent

Gas purging for aluminum alloy gravity and low pressure casting

■Our Sintered Vent has 4 to 30 times larger pores than conventional vent and offers the best results even with smaller outer diameter. ■For larger casting of aluminum alloy, vent with 0.5mm pore diameter as an effective diameter should be proper application.
For smaller and higher pressure casting, 0.3mm pore diameter is recommended.
■With better purging performance, more accurate molding is available without lack of filler and missed molding at convex tip.

For gas vent for injection molding

■Effectively purge air in the cavity and prevent gas burn and missed molding. ■For injection molding of resin, attach the Sintered Vent with 0.05mm+/- at the outlet to purge gas. ■Easily move the welded line. ■Reduces the shot cycle and significantly improve productivity. ■Inject the vent in the center of ejector pin or locations of underfill to maximize the advantages of the vent.

For gas vent for blow molding of resin

■Gas vent for blow molding of resin for automotive parts and household and industrial resin containers, Sintered Vent with 0.3 to 0.5mm pores are applied.

We also provide SUS W-type vent for injection molding.

■ SUS vent is effective to prevent decay caused by gas. W-type vent has more porosity than P-type vent with the same pore diameter.

Instruction for Use of Sintered Vent

1. Do not damage the pore surface by metals and hard materials. It will cause clog and chip.
2. Do not polish/grind the pore surface.
3. Use resin or wooden hammer to inject the vent.

■Our Sintered Vent has 4 to 30 times larger pores than conventional vent and offers the best results even with smaller outer diameter. ■For larger casting of aluminum alloy, vent with 0.5mm pore diameter as an effective diameter should be proper application.
For smaller and higher pressure casting, 0.3mm pore diameter should work the best.
■With better purging performance, more accurate molding is available without lack of filler and missed molding at convex tip.
