2K injection
molding is also known as two-shot injection molding or double shot injection molding or bi-color
injection molding, and it is a manufacturing process used to create plastic
molded parts from two different materials. 2K molding technology is popular in the market, which is widely used in the line of electronic parts,
sport goods and other related molded parts.
2k injection
molding is one of molding methods used to produce plastic products, which is
similar as overmolding. However, there may be a distinct point between 2K
injection molding and overmolding. Overmolding is a process to make plastic
parts with secondary operation, which needs two sets of molds, to be separatedly molded in injection machine. One part called substrate, is placed into
the second-shot mold, then melted material will surround the substrate to
create final overmolding part.
While 2k injection
molding requires specific molding machine--double shot injection molding
machine, which also requires two material to be compatible, and the melting
point of first injected material must be higher than the second. Two kinds of
materials are injected onto the same injection molding machine and form one
final product. 2k injection mold manufacturing has technically demanding, and the
products will be made with stable quality, beautiful appearance and lower unit
cost. This is the reason why more and more manufacturers adapt 2k injection
molding for mass production.
