If the requirements are not met by one specific material, two or more thermoplastics can be combined to close the gap. The second (over-mold) material is either injected onto one side of the insert or sometimes completely surrounds the insert. Only in the last one decade applications have emerged which demand combining hard and soft thermoplastic materials.
