Mold insert for tubing-forming mold apparatuses

A mold for an apparatus for forming a polymeric product, the mold comprising:

• an outer component defining a first inner cavity having a first diameter;
• and
• an inner component configured to be disposed at least partially inside the first inner cavity of the outer component, the inner component having an inner surface which defines a second inner cavity having a second diameter smaller than the first diameter, the inner component comprising:
• a first subcomponent having a first inner surface;
• and
• a second subcomponent having a second inner surface,
• wherein the first and second subcomponents are configured to couple together, and the first and second inner surfaces are configured to define the second inner cavity for receiving a polymeric material during molding of the polymeric product.

A method of forming a mold for an apparatus for forming a polymeric product, the method comprising:

• coating a first inner surface of a first subcomponent;
• coating a second inner surface of a second subcomponent;
• forming an inner component by coupling the first subcomponent with the second subcomponent to define a second inner cavity for receiving a polymeric material during molding of the polymeric product;
• and
• at least partially disposing the inner component inside a first inner cavity of an outer component.
