High Density Heaters are compact, high-performance heating elements designed for applications that require rapid and uniform heat transfer. Built with premium-grade stainless steel or Incoloy sheaths and insulated using high-purity magnesium oxide, these heaters ensure exceptional durability, thermal conductivity, and resistance to oxidation. Their high watt density allows efficient heating in limited spaces, making them ideal for plastic injection molding, hot runner systems, packaging machines, and sealing bars.
