Hi all. Do you know where can I find some information about Double Injection Process?

Juan,

Are you looking for an overmolding process such as plastic over plastic or plastic over metal? We do get involved in these processes and are located in Saltillo Coahuila.

Best Regards,

Hi Juan,

The term "double injection" means different things to different people and different business environments. I'll assist to point you in the proper direction, to best of my abilities, once I understand exactly what it is you are looking for. There are many variations and combinations of molds and machines and labor to accomplish a single end product made of two materials.

Hi Juan,
There are mainly 2 types of double injection.
1. Over molding, which is a second molding over a main part.
2. Insert molding, which is a second molding of a main part on a small part.
There are also different mold constructions of doing the over or insert molding, which are change core or change cavity or change core and cavity. There are also different technology to hold the first part, like vacuum, statics and gavity.
Some of the suppliers can do particular type/types or constructions. So, it is need to understand your parts and processing type first.
