Super Vent Core Vents

Super Vents are self-cleaning and feature an opening rate of more than 43%. Using these vents will solve the problem of clogging which can affect the continuous operation of a core molding machine during no-bake molding. The 43% opening rate (compared to an average of 13% for slotted vents and 30% for screen vents) results in more effective and efficient venting. 

Brass – Screen Core Vents

This brass body vent offers a high venting area with a corrosion resistant, nickel-copper alloy screen. 

Nylon Core Vents

Nylon Vents are injection molded for high precision. These vents provide a ‘non-stick’ surface combined with the toughness of nylon. Ideal for medium to high pressure molding, they are highly recommended for use in blow squeeze machines, v-process, and with cold box and CO2 sand systems. 

Sintered Vents

Gravity, Low Pressure/Vacuum Casting & Die Casting Applications
Sintered Vents provide an innovative way to decrease molding defects while improving venting efficiency.

Applications
Sintered vents are inserted into molding dies to assure sound castings. They allow the escape of gas and prevent the passage of smelt.
