Bi-injection & 2K molding


2-Shot moulding(2K molding) is an innovative manufacturing process used to produce complicated moulded parts in multiple materials, and can be used for a variety of product designs across all industries.

2-Shot moulding(2K molding) optimises the co-polymerisation of hard and soft materials to create a powerful molecular bond.

Ming-Li uses thermoplastic elastomers and plastics for the 2-Shot moulding(2K molding) process as traditional thermoset compounds (such as nitriles, fluorocarbons, EPDM’s) are not suitable.



Ming-Li typically uses the following thermoplastic materials for 2-Shot moulding(2K molding):

Styrene Block Copolymers (TPE-S)
Thermoplastic Polyurethane Block Copolymers (TPE-U)
Copolyesters (TPE-E)
Copolyamides (TPE-A)
Olefinic Thermoplastic rubbers (TPE-O)

Ming-Li typically uses the following plastic materials for 2-Shot moulding(2K molding):

Polyamide (PA/Nylon)
Polybutylene Terephtalate (PBT)
Polycarbonates (PC)
Polypropylene (PP)

The 2-Shot moulding process allows us to design and manufacture complex, multiple material parts for our customers to perform a sealing function.

Additionally, the multi-shot moulding process can also be used as a cost effective method to bond materials in different colours for cosmetic purposes.
