Over last decade, we have built over 300 overmould injection molds for various applications, from cellphones housings and cases, submarine cameras, instrument tool handlers to kitchen kits.
Here in corelmould, we provide you the suitable solution for your project. Whether economic pursuit or precision demands, we communicate and find the answer.
TPE overmould add a soft layer to grab area for better touch and more grab force
Electronics get waterproof with 2nd layer of soft plastic. In cell phones, soft plastic was added to the assembly edges and making the keyboards, so it become IP68 waterproof.
Not just giving soft touching, double injection make parts more beautiful.

The beauty of 2 plastic,2 colors, 2 feelings
Double injection mould, sometimes referred as over-mould injection is mainly used to make one part of two different plastics and/or colors.First inject plastic of higher melting point, then the other plastic of lower melting point.Therefore the 2nd injection wont affect the 1st injection result. In most cases, the 2nd plastic is soft plastic like TPU/TPE etc. TPU/TPE has lower melting point and soft touch.
The purposes of double injection mould are basically used for:
Soft and firm touch
There are 2 common kinds of double injection molds.1 is to injection 2 plastics in the same injection machine,rotation-ally, which is more efficient and fast ; 2 is to separate them into 2 molds ,which is lower in tooling cost.
