The combination of the heated metal tip and the high pressure of the plastic extrudate produce welds on rotomolded parts that are water and airtight. Rotational molders reduce scrap parts by using the Injectiweld to seal seams, blow-bys, and voids. They also use the welder to add baffles, flanges, and fittings onto their plastic products. The strength of the weld is very close to the strength of the virgin material so there is no need to worry about weak spots. To add to the quality of these welds, Drader can produce custom welding rod using rotomolded grade resin for an exact color and material match.
