Introduction
ULTRAFLEX POWER is well known manufacturer of induction heating and precision casting equipment, with a product range specifically engineered for the demands of jewellery manufacturing and precious metal processing. Their systems cover the full casting workflow — from melting the metal to casting it, whether by centrifugal force or pressure — and extend into broader industrial induction heating applications for manufacturers who need controlled, repeatable heat delivery at production scale.
Induction technology has become the standard for serious jewellery casting operations because it offers something gas and resistance heating cannot: precise, controllable, non-contact heating that responds immediately to operator input. ULTRAFLEX POWER’s engineering is built around extracting the full advantage of that technology — in machines that are practical, durable, and suited to real production environments.
NJTPL has been supplying ULTRAFLEX POWER systems to Indian jewellery manufacturers and casting facilities — providing genuine product access, technical guidance, and local support from Mumbai.

Why Induction Technology Changes Jewellery Casting
The casting machine is the centrepiece of any lost wax casting operation — and the melting and casting method it uses determines more about output quality, metal cleanliness, and production efficiency than almost any other variable. Traditional gas torch or resistance furnace melting is slow to respond, difficult to control precisely, and exposes the metal charge to oxidation and contamination during the melt cycle.
Induction melting and casting eliminates most of these problems. Because induction heats the metal directly through electromagnetic energy — with no combustion, no exposed heating element, and no flame — it delivers:
- Faster melt times compared to gas or resistance heating — reducing cycle time per flask
- Precise temperature control — the operator sets and holds the exact melt temperature required for the alloy, reducing over-heating and metal degradation
- Cleaner melts — no combustion gases, no flame contact, significantly reduced oxidation of the metal charge
- Consistent energy delivery — induction power is stable and repeatable, so every melt cycle behaves the same way
- Safer working environment — no open flame, no gas lines, no combustion risk on the production floor
- Lower energy consumption compared to equivalent resistance furnaces at the same melt capacity
For Indian jewellery manufacturers casting gold, silver, and platinum alloys, ULTRAFLEX POWER’s induction-based casting systems deliver the melt quality, casting consistency, and production efficiency that modern jewellery manufacturing demands.
Product Range
CS Digital
The CS Digital is ULTRAFLEX POWER’s centrifugal casting machine — designed for precision gold and jewellery casting applications where centrifugal force drives the molten metal into every detail of the investment mould. Induction melting within the machine ensures a clean, controlled melt before each cast, and the digital control system gives the operator precise management of melting parameters and centrifugal speed. The result is consistent casting fill, good surface detail reproduction, and reliable output across production runs.
PressCast
The PressCast is ULTRAFLEX POWER’s pressure casting machine — an alternative to centrifugal casting that uses controlled gas pressure to drive the molten metal into the mould. Pressure casting is particularly well suited to thin-section jewellery, filigree work, and designs where uniform mould filling under consistent pressure produces better results than centrifugal force. The PressCast combines induction melting with precise pressure control, giving the operator a repeatable, controllable casting process for demanding designs.
EasyMelt
The EasyMelt is ULTRAFLEX POWER’s dedicated induction melter — designed for melting precious metals cleanly and efficiently without the casting function. It is the right tool for manufacturing operations that cast separately, alloy at the bench, or need a reliable, controlled melt source for refining, granulating, or preparing metal for rolling and drawing. Fast melt times, precise temperature control, and a compact footprint make the EasyMelt a practical induction melting solution for jewellery workshops and small production facilities.
Smart Power Systems
ULTRAFLEX POWER’s Smart Power Systems are advanced induction heating units designed for precision-controlled industrial heating applications beyond standard melting and casting — including brazing, annealing, hardening, and specialised thermal processing in jewellery and industrial manufacturing environments. For manufacturers who need programmable, repeatable induction heat delivery for specific processes, the Smart Power Systems provide the control and power output to do so reliably.
Why Indian Casting Facilities Choose ULTRAFLEX POWER Through NJTPL
Cleaner metal, better castings
Induction melting produces a significantly cleaner melt than gas or resistance heating — less oxidation, less gas absorption, less contamination. Cleaner metal means fewer casting defects, better surface quality, and less remedial finishing work on the output.
Precise temperature control protects your alloy
Over-heating gold and platinum alloys during melting causes metal degradation, colour shift, and alloy composition changes that affect the finished piece. ULTRAFLEX POWER’s induction systems hold the melt at the exact temperature required — protecting both the metal and the casting.
Faster cycle times improve production throughput
Induction melting is significantly faster than gas or resistance heating for the same metal charge weight — reducing the time between flasks and improving the number of casts per shift.
Two casting methods for different production needs
The CS Digital’s centrifugal casting and the PressCast’s pressure casting suit different jewellery types and design requirements. NJTPL can help you identify which method — or which combination — is right for your production mix.
Safer working environment
Replacing gas torch melting with induction removes open flame, gas lines, and combustion risk from the casting area — a meaningful improvement in workshop safety for any facility.

Frequently Asked Questions
What is the difference between the CS Digital centrifugal casting machine and the PressCast pressure casting machine — and how do I choose?
Both machines melt with induction and cast into investment moulds, but they use different forces to fill the mould. The CS Digital uses centrifugal force — well suited to most standard jewellery casting applications and generally preferred for heavier section pieces. The PressCast uses controlled gas pressure — better suited to thin-section work, filigree, and designs where uniform pressure produces more consistent mould filling than centrifugal force. NJTPL can help you assess which method suits your design mix and casting requirements.
Is induction melting suitable for all precious metals used in Indian jewellery manufacturing — including 22ct gold and platinum?
Yes. ULTRAFLEX POWER induction systems are compatible with gold across all carats including 22ct and 21ct, silver, and platinum alloys. The precise temperature control that induction provides is particularly valuable for platinum, which requires very high and tightly controlled melt temperatures.
What is the EasyMelt used for if I already have a casting machine with induction melting?
The EasyMelt serves as a dedicated melt source for operations that need melting capacity separate from the casting machine — for alloying, granulating, preparing metal for rolling and drawing, or as a secondary melt station when casting volume requires the casting machine to be used continuously. It is also the right choice for operations that cast using a separate casting unit and need a controlled, clean melt supply.
Can ULTRAFLEX POWER Smart Power Systems be used for annealing and brazing applications in jewellery manufacturing?
Yes. The Smart Power Systems are designed for precision industrial heating applications including annealing metal stock, induction brazing, and other controlled thermal processing applications beyond standard melting and casting. NJTPL can advise on suitability for your specific process requirements.
How does induction casting compare to vacuum casting for jewellery manufacturing?
Induction casting and vacuum casting address different aspects of the casting process. Induction refers to the heating method — how the metal is melted. Vacuum casting refers to whether the mould is evacuated before or during the cast to improve metal fill. ULTRAFLEX POWER systems can be configured to work with vacuum-assist casting setups. NJTPL can advise on the right configuration for your specific casting requirements.
