Spinnerets
Since 1973, Hindustan Platinum has played a crucial role in the production of precious metal spinnerets and has served the man-made fibre industry for over a quarter of a century. In the current scenario, Hindustan Platinum remains the country’s exclusive maker of spinnerets and also repairs and refabricates old and worn out spinnerets, regardless of the original maker.
Manufacturing Techniques
Our sophisticated process of production of spinnerets has consistently been driven to meet the challenges created by an increasingly innovative industry to manufacture products with outstanding attributes. Hindustan Platinum has a vast knowledge and expertise in spinneret technology. It gives us the flexibility to work on customized designs, based on customers’ specific needs. When attending to a precious metal spinnerets, be it a standard design or a specific one, we ensure that the metal or alloy used has the following characteristics:
- Extremely resistant to corrosion
- Stable enough to continuously resist deformation
- Recyclable

Platinum Labware
With exceptional chemical stability and superior resistance to oxidation and corrosion, platinum and platinum alloy crucibles and dishes are widely used as reliable equipment in research and development applications.
Platinum Labware
Considering the chemical stability & resistance to oxidation & corrosion, crucibles and dishes of platinum & platinum alloys are mainly used as equipment in research & development
Our indigenous production processes allow us to customise parameters like thickness, reinforced rim, pouring lip, varying sizes and shapes such as cylindrical or conical and with different types of lids as per individual specifications in pure Platinum, Platinum/Rhodium or Platinum/Gold.
The crucibles size ranges from 5 cc to 250 cc for “AZ” and 8 cc to 200 cc for “BZ”.
Crucibles in these series have nominal capacities ranging from 5cc to 250cc. These crucibles are designed with extra thick base to withstand heavy wear. Unless otherwise specified crucibles are always supplied having plain rim and with lid. The purity of Platinum used for manufacture of these crucibles is at least 99.95%.

Platinum and its alloy possess the following properties to use for laboratory apparatus:
- Higher strength
- High melting point
- Ductility
- Corrosion resistance
- Oxidation resistance
And therefore, Platinum and its alloy are widely used as a analytical laboratory apparatus. The properties of Platinum and its alloys are summarized as under:
This Platinum group metal alloy melting point as high as 1850 degree Celsius. This alloy has greater hardness and higher strength
This alloy universally accepted for Crucibles and casting moulds for spectro-graphics analysis by x-ray fluorescence (XRF). This alloy has property of higher temperature strength than pure Platinum and has “non-wetting” property for easy removal of the sample after fusion and allows many reproducible assays.

Temperature Measuring Products- Platinum and Rhodium Wires
We manufacture platinum wires of a very high standard, uniform composition and free from chemical or physical defects.
Platinum and its alloys are reliable sensing elements in high temperature measurement. We make temperature sensing products that give better process control.
Platinum and Platinum/Rhodium thermocouple wires are widely used for optimum accuracy and stability for measuring temperatures ranging from 1000°C to 1800°C. These are produced from high purity metals to maintain accurate e.m.f. values within tolerances of international standards.

Platinum – Platinum/Rhodium throwaway tips of wire diameter below 0.1 mm. are now used for their economy, to measure high temperatures, particularly in Steel Plants. We make high temperature application wires for throw-away tips of wire diameter up to 0.025 mm. Great care is taken to maintain accuracy of the relation between the temperature and e.m.f, within the standard tolerance.

Pure Platinum Wire for RTD
Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically made of Platinum, Nickel, or Copper.
Platinum resistance thermometers (PRTs) offer excellent accuracy over a wide temperature range (from –200°C to +850°C). The most common type (Pt 100) has a resistance of 100 ohms at 0°C and 138.4 ohms at 100°C. There are also Pt 1000 sensors that have a resistance of 1000 ohms at 0°C.
Platinum and Platinum/Rhodium wires are employed for winding the furnaces for the temperature above 1000°C because of their high melting point and resistance to reaction with oxygen in air. Although these resistors cost more compared to those made of base metals, their longer life and higher resale value make them far more economical for furnace winding. These wires can be reworked into new ones at nominal charges when scrapped.
Properties of Platinum Furnace Winding Wires
