We study a mechanism to create a vorton or three-dimensional skyrmion in phase-separated two-component BECs with the order parameters Psi(1) and Psi(2) of the two condensates. We consider a pair of a domain wall (brane) and an antidomain wall (antibrane) stretched by vortices (strings), where the Psi(2) component with a vortex winding is sandwiched by two domains of the Psi(1) component. The vortons appear when the domain wall pair annihilates. Experimentally, this can be realized by preparing the phase separation in the order Psi(1), Psi(2), and Psi(1) components, where the nodal plane of a dark soliton in Psi(1) component is filled with the Psi(2) component with vorticity. By selectively removing the filling Psi(2) component gradually with a resonant laser beam, the collision of the brane and antibrane can be made, creating vortons.
