<p num="1"><br/><br/><br/> An oven for baking a batch of parts has a housing having side walls <br/>and a top wall defining a closed container with a closed top end and an open <br/>downwardly facing bottom end. Loading/unloading occurs at the bottom end onto <br/>a <br/>carriage raised to the top end where baking occurs. On each side is provided <br/>an <br/>array of heating elements below the top. A shield is located in front of the <br/>heating <br/>array so as to block direct radiation onto the parts to prevent over-heating <br/>as the <br/>carrying arrangement passes the heating array to be unloaded. The shield <br/>generates an upwardly flowing air stream to carry the heat to the top. The <br/>heating <br/>elements are mounted with their lower end in a connection box with a collar <br/>and <br/>insulated heat shield above the box to keep the electrical connections cooled.<br/><br/>
