2-Shot moulding 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 optimises the co-polymerisation of hard (or soft) plastics and thermoplastic elastomers (TPE’s).
A 2-Shot mould is designed with a top and bottom cavity. During the moulding process the 1st material is injected into the top cavity and the mould opens and rotates. The 1st material is injected into the top cavity again, while the 2nd material is injected into the bottom cavity simultaneously. The mould then opens and the parts are ejected from the bottom cavity; the mould rotates again and then whole process is repeated.
Ceetak typically uses the following thermoplastic materials for 2-Shot moulding:
• Styrene Block Copolymers (TPE-S)
• Thermoplastic Polyurethane Block Copolymers (TPE-U)
• Copolyesters (TPE-E)
• Copolyamides (TPE-A)
• Olefinic Thermoplastic rubbers (TPE-O)
• Ceetak typically uses the following plastic materials for 2-Shot moulding:
• Polyamide (PA/Nylon)
• Polybutylene Terephtalate (PBT)
• 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.
