Fabricated Baskets
These stackable baskets provide uniform load distribution, better interlocking and the least amount of distortion. With these parameters taken care of, the overall usable life of these Baskets is much longer. The side walls with extra reinforcements efficiently transfer the load to the heart of the furnace “The Base Tray”. This reduces deformation. The wire meshes can be custom built as per the requirement.
These customisable baskets have been our bestselling baskets for Pit Type furnace. The unique feature of these Baskets is that the corrugations offer extra strength to the side walls which prevents buckling of the baskets. To add to this, the riveted joints and the special lifting and locking mechanism offer greater resistance to deformation thereby resulting in a much better life. The oil / gas circulation holes can be made as per the customer’s requirement. These baskets are bottomless and have to be paired with a replaceable cast grid
These customisable heavy duty wire mesh baskets made out of AISI 310 grade and other higher grade alloys offer the best Open Space: Load ratio. They offer extended and trouble free operational life with minimum warpage at the furnace operating temperatures

Fusion Welded Fixtures
We are the first ones to offer fusion welded mesh for heat treatment purposes. Fusion welded baskets and weld meshes offer very good life as compared to the same fabricated fixtures using conventional welding. Since an inter-atomic bond is established by fusing two surfaces, there is absolutely no use of filler materials or welding electrodes. Hence, there is no question of weld cracking or failing at elevated temperatures.
Wire Mesh, Expanded Mesh, Mesh Belt Conveyors
Wire meshes in almost any shape & size are offered in various heat resistant alloys. For bottom mesh on base trays, suitable reinforced openings can also be provided for inserting Corner Posts etc.
Heavy duty Expanded Mesh can be offered which can take heavy load without increasing much dead load on furnace thereby increasing productivity.
Mesh belts made from high Ni/Cr alloys such as AISI 310, 314, Inconel, Incoloy etc. are offered in a range of specifications with or without side guards. Edge welding is done using flux free Argon Arc welding process for optimum performance.

Tactile Ground Surface Indicators and other General Engineering components
Tactile Ground Surface Indicators for Roads, Ramps, Elevators, Staircases etc.:
Tactile Ground Surface Indicators are used to assist the visually impaired or blind on their way around a place. These have been specifically designed so as to make them aware of immediate obstacles on the path or even hazards.
These indicators are installed on the ground surface and resemble a long sequence of slightly raised bars or small mushroom-like domes. Just like paved units on the floor, Tactile Ground Surface Indicators are drilled into the surface of the ground to fix them permanently. In many cases, you might also find these ground indicators to be drilled along into the floor mattress on the ground.
Apart from different sizes, these are also available in different colour coding to enable to convey navigational instructions.

Investment Cast fixtures
Heat Treatment
Investment casting is a cost-effective and efficient process with many advantages in fixture manufacturing:
Accuracy: Investment casting can create complex shapes with exceptional accuracy and tight tolerances. Limitations in green sand moulding process of higher section thickness can also be overcome using this process. This not only reduces the casting cost, but also helps in reducing dead load on the furnace thereby increasing productivity.
Design flexibility: Investment casting allows you to cast multiple parts together, which is more cost-effective than welding them separately.
Smooth finish: Investment casting produces a smooth surface finish that often requires little to no additional finishing. This reduces the cost of finishing.
Minimal waste: Investment casting is considered highly efficient because it creates minimal waste compared to other casting processes. Since there is reduction in wastage, lesser costs are involved.
Compatible with low- and high-volume manufacturing: Investment casting is a cost-effective option for both low- and high-volume production runs.
More environmentally friendly: Investment casting is more environmentally friendly than other metal fabrication processes.
Investment casting is used to create components for a wide range of industries including Auto, Aerospace, Medical, Military, Petrochemical, Marine, Steel, Cement etc..
Stress analysis:
We at Nisha use software based simulation to optimise shapes and sections which enable us to load heavier parts on lighter fixtures. This reduces the dead load in your furnace.
