1. A mold assembly comprising:
- a bottom mold portion comprising;
a bottom block comprising a top surface, anda plurality of cavities in the bottom block extending downwardly from the top surface to a first depth;
a top mold portion comprising;
a top plate positioned opposite and at a first distance from the top surface of the bottom block, anda plurality of protrusions extending downwardly from the top plate, wherein each protrusion of the plurality of protrusions forms a seal at the top surface of the bottom block; and
a middle mold portion comprising a wall that forms a seal between the top plate and the bottom block around the periphery of a void space between the top plate and the bottom block.

Abstract
Modular tubing apparatuses for use in a shell-and-tube heat exchanger are described. Multiple apparatuses may be connected in series to form a high density, small tube diameter, long length tube apparatus assembly. Casting molds for forming modular tubing apparatuses are likewise described, including methods for casting and electrochemically machining such apparatuses.
