ABSTRACT:
A flashless mold for encapsulating axial leaded devices (24) with a protective plastic material. The plastic material is introduced through a gate (27) which is positioned such that the leads of the electronic devices (24) are not wetted by the plastic material. This gate design, combined with a tight fitting groove for the terminal wires eliminates flash on the terminal wires. A spring retainer (28) acts to hold the individual devices accurately in place in the mold cavity facilitating loading and unloading of the mold.
