1. Overview

• Consist of bond strength of about 80MPa or more, thermal conductivity of 100 W/(m*k), not to mention higher cooling efficiency than the existing die casting mold cooling channel. It also possesses explosion prevention hetero-bonding mold design and fabrication technology.

• With optimized processing technology by calculating the explosive charge amount, distance of Cu to be bonded as well as its thickness-length, it creates the bonding technology for even and firmly bonded pure copper to the cooling channel

2. Characteristics

• Unlike solid phase diffusion method, it is usually carried out under atmospheric pressure and it can do up till 30 explosions joined to cooling channel.

3. Issuance Category (Effective Period)

• August 30th, 2018 ~ August 29th, 2020
