Technical Data List
|Q1||What are the advantages of NGK Chill-Vent?|
|A1||There are 3 main advantages:
|Q2||Why is it possible to enlarge the cross section?|
|A2||NGK Chill-Vent utilizes Beryllium Copper alloy (BeA-MC9) which has 5 times the thermal conductivity of tool steel.
This means that NGK Chill-Vent has 5 times the cooling rate.
|Q3||Why are aluminum/vent reactions eliminated?|
|A3||The main reason is adoption of Beryllium Copper alloy.
Aluminum is rapidly cooled and solidified by NGK Chill-Vent before reactions can take place.
|Q4||How compact is the design?|
|A4||NGK Chill-Vent is only half the size of steel designs needed under the same die casting conditions according to in-house comparisons.|
|Q5||What is the difference between NGK Chill-Vent and C-block?|
-Be-Cu chill-vent is made to order per customer's specification.
-NGK's U.S. patented standard chill-vent is ready-made.
|Q6||Are there any important points for use ?|
|A6||Be sure to pass coolant through the inside.|
|Q7||Is there any damage from aluminum erosion?|
|A7||In general there should be no erosion problem because Chill-Vent is mounted away from the aluminum intake.|
|Q8||How durable is NGK Chill-Vent?|
|A8||NGK Chill-Vents have now been used to mass produce over 100,000 shots without problems, Beryllium Copper alloy has superior hardness and strength compared with other copper alloys.|
|Q9||Is there any mechanical damage due to embedded aluminum fragments?|
|A9||If aluminum fragments remain inside the Chill-Vent, it may lead to mechanical damage.
An air-blowing system should be used to reduce problems.
|Q10||What is the role of Guide Frame for C-block?|
|A10||Guide Frame is optionally available to prevent damage, for example, from being bumped or hit with a hammer.|
|Q11||Is Guide Frame always necessary?|
|A11||No, it is only required in rare cases.
Many users adopt NGK Chill-Vent for 250T-2500T D/C machine without the Guide Frame.
|Q12||What are other technologies related to NGK Chill-Vent?|
|A12||NGK offers the following technologies:
