Q 1 What are the advantages of NGK Chill-Vent?
A 1 There are 3 main advantages:
  1. Allows extremely large cross section to improve gas flow.
  2. Eliminates aluminum eruption and Al/Vent reactions.
  3. Simplifies die design to reduce mold size.
Q 2 Why is it possible to enlarge the cross section?
A 2 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.
Q 3 Why are aluminum/vent reactions eliminated?
A 3 The main reason is adoption of Beryllium Copper alloy.
Aluminum is rapidly cooled and solidified by NGK Chill-Vent before reactions can take place.
Q 4 How compact is the design?
A 4 NGK Chill-Vent is only half the size of steel designs needed under the same die casting conditions according to in-house comparisons.
Q 5 What is the difference between NGK Chill-Vent and C-block?
A 5 NGK Chill-Vent
-Be-Cu chill-vent is made to order per customer's specification.
-NGK's U.S. patented standard chill-vent is ready-made.
Q 6 Are there any important points for use ?
A 6 Be sure to pass coolant through the inside.
Q 7 Is there any damage from aluminum erosion?
A 7 In general there should be no erosion problem because Chill-Vent is mounted away from the aluminum intake.
Q 8 How durable is NGK Chill-Vent?
A 8 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.
Q 9 Is there any mechanical damage due to embedded aluminum fragments?
A 9 If aluminum fragments remain inside the Chill-Vent, it may lead to mechanical damage.
An air-blowing system should be used to reduce problems.
Q 10 What is the role of Guide Frame for C-block?
A 10 Guide Frame is optionally available to prevent damage, for example, from being bumped or hit with a hammer.
Q 11 Is Guide Frame always necessary?
A 11 No, it is only required in rare cases.
Many users adopt NGK Chill-Vent for 250T-2500T D/C machine without the Guide Frame.
Q 12 What are other technologies related to NGK Chill-Vent?
A 12 NGK offers the following technologies:
  1. Be-Cu is available for various types of permanent molds such as LPDC, GDC and shell mold.NGK has much experience in the design and manufacture of Be-Cu molds.
  2. Additionally, NGK's original coating technique is available for preventive maintenance.
