NTB INFRA-RED HEATERS

Sealed ceramic heaters emit electromagnetic radiation which heat the articles on which these waves impinge. In these heaters the resistance heating element is totally encased in a highly thermal shock and corrosion resistance glazed ceramic material. These operate in the 150-750C temperature range to emit wavelength from 2 to 10 microns, and are extremely efficient with a peak emissivity approaching 0.94 of the “ideal” black boady.This energy is readily absorbed by process materials like water, organic solvents,plastics,paints,adhesives,ceramic ,glass,metals,food,paper etc., in heating drying and curing operations. Due to these characteristics ,sealed ceramic heaters enjoy advantages over other Infra-red heat sources like; Metal foil Radiation, Quartz Tubes,Quatz Lamp, Gas Fired Radiant Burners, Sheathed Tubular Heaters.

Ceramic Infra-Red Heaters are suitable for 230 volts.Standatrd Power ratings are 100-150-200-250-300-400-500-600-800-1000 Watts. Standard Sizes are 245 x 60mm 122x60mm 122 x122mm, 292x92mm, 125mm Diameter.NTB can manufacture IR Heater in customised size, Wattage and to operate at 110,380 or 440 volts.

BrandNTB

Advanced ceramics, which ensure a perfect fit for sheet metal and nuts and are subjected to temperatures of up to 800 °c, have long replaced metal in the production of welding pins. Metal cannot compete with ceramics with regard to insulating properties, resistance to temperature change, and minimal wear and tear due to the high degree of hardness and durability. Yet another advantage of ceramics is their smooth polished surface, which prevents welding spatter from adhering.

However, service life does face limitations when it comes to welding pins made of commonly used zirconium oxide ceramics. Over time, this material is likewise unable to stand up to the 30 to 40 kilo amperes that flow through the copper and the required working temperature of 800 °c, and thus suffers from wear.

This is why our NTB HITECH CERAMIC materials experts have developed the ceramic material — especially for use in the field of welding technology. Extreme hardness and flexural strength, a high level of thermal shock resistance, electrical insulation, temperature resistance, and high tensile and compressive strength make ceramics a material that withstands the working conditions of projection welding and ensures a significantly longer service life. For comparison: while commonly used ceramic welding pins exhibit service lives 40 times that of metal, the service life of our ceramics is an additional forty times greater than that of centring pins made from metal oxide.

Knives for Pharmaceutical capsules

NTB Knives is used to cut Pharmaceutical hard capsules.NTB Knives for pharmaceutical capsules use zirconia ceramic with high strength and toughness, featuring the following compared to the typical knives made of cemented carbide or stainless steel.

1) High-strength and high-toughness zirconia is a single-phase material consisting of superior crystal grains, which achieves better resistance against chipping of edges, leading to the improvement of cutting performance.

2) There is no need of rustproofing treatment because no corrosion occurs in a normal – atmosphere environment, which achieves the better cleanness for product.

We have the capability and the inclination to develop new products and meet new challenges. Prototype quantities of extremely complex shapes can be made by Slip Casting. A multiplicity of shapes is possible with High and Low Injection Moulding. Our normal production capability covers Iso-pressed parts (Dia. 225mm x 600mm), Extruded parts(Dia. 50mm), Hydraulically parts (Dia. 200mm x 60mm ) Mechanically Pressed parts (Dia. 50mm x 50mm). Slip Casted components typically exhibit tight tolerances.

 

Tooling costs are highly economical in India. Consequently, short production runs of 50 to 200 parts are typically competitive. Reliable tooling vendors support our dedicated tool-room. This allows quick turn-around times on customized and prototype order/s.

A choke is used to control the flow of fluids and is usually mounted on or close to the Christmas tree. High pressure gas/oil, with abrasive sand minerals passes through these chokes at high speed causing rapid wear. Bean chokes contain a replaceable insert, or bean, made from hardened steel/ceramic or stainless steel/tungsten carbide or similar durable material. NTB Bean Chokes are lined with a high hardness, abrasion and corrosion resistant 98.5% Alumina or Tungsten Carbide liners, to protect them from corrosive and abrasive wear.

 

NTB Bean Chokes are exported all over the world and are known for their international standards timely delivery. NTB manufactures a big range of bean chokes to match 'OCT'Type FC140, 'Thronill Craver', Gray Tool', Cameron' types. These are manufactured with a precise diameter hole that forms the choke, through which all the abrasive/corrosive fluids must pass. Beans are available in a complete range of sizes, generally identified by the choke diameter stated in 64ths of an inch. For orifice size less than 14/64" for more precise flow control, beans are offered in sizes of 10% increments (5% increments available between orifice sizes 6/64" and 14/64"). NTB offers choke beans hardened steel/tungsten carbide stems for the above makes other custom designed flanged positive chokes, flanged threaded adjustable chokes stems/seats.
