TABLE OF CONTENTS Also known as dual injection, sandwich moulding, 2K (or 3K). It can be recognised by the production of a defined skin and core structure. The core is fully encapsulated, to produce a sandwich like moulding.
This is simultaneous injection of different materials through different gates as opposed to through the same gate as in co-injection moulding.
Also known as marbleising, this is simultaneous injection of different materials through the same gate, with limited mixing. This produces a pattern of either regular or irregular colour distribution such as marble type effects.
