MOLD COOLING Spiral Brass Plug Baffles
MOLD COOLING Straight Brass Plug Baffles
Spiral Baffles Spiral baffles improve cooling balance by creating turbulent action in the channel, reducing laminar or straight-layered flow patterns and providing efficient coolant movement.
DME Brass Plug Baffles, available in both straight and spiral styles, are constructed entirely of high-quality brass with blades brazed to the plugs for long, dependable service. They provide a high-pressure seal through a deliberate difference of taper between the plug and the tapped hole.
The function of the baffle is to split the drilled waterline into two equal channels. As the heating or cooling medium enters, the baffle diverts the flow to travel up to and over the end of the baffle and down the other side. Clearance must be provided between the end of the baffle and the end of the drilled channel to provide adequate flow. See Dimension “C” for approximate clearances.
