Nisha Engineers, India

Being OE supplier to many furnace manufacturers, we have a large inventory of standard patterns for base trays for almost all major furnace manufacturers. We offer various sizes of Base Trays for Sealed Quench, Continuous or Vacuum furnaces.

We design trays for new applications alongside modifying the designs of the currently used trays for optimum service life in the most extreme applications. Trays are also available with built in rail guide for Pusher type furnaces. Reversible base trays with in-built rail guide are also available.

These are often cast in high Ni/Cr alloys such as HK, HT, HU, HX etc. using green sand molding processes. Our commitment to high quality standards assures a considerably longer service life for our base trays than offered by other suppliers.

We are your replacement source for top quality furnace spares and fixtures.
