But here&rsquo;s the problem: if your infrared lamps aren&rsquo;t pulling their weight equally across the heating bank, you end up with hot spots and cold zones. In a big batch, that’s a nightmare. Some pieces come out perfect, while others warp or just snap. Usually, it all comes down to the lamps not being identical.</p>
