J -2r Series IV - Resistance Vacuum Casting Machine
BECAUSE EVERY CASTS COUNTS
Purchasing new equipment requires making difficult decisions.
How is the need for increased production capacity and improved
quality met without tying up a lot of extra resources? Howare
today's investments paid back quickly and yet kept solid enough
to meet future business goals?
The NEUTEC J-2r IV is designed to meet these needs.
For a fraction of the cost of a competitive machine, the J-2r IV gives you superior castings, and greater production capacity.
This exceptional machine combines advanced technology with a practical
design to give you the casting capability you need now and well
into the future.
PERFORMANCE
Oxide-free metal and accurate casting temperatures produce exceptionally
high-quality pieces every time you cast with the J-2r IV. It's fast cycle times and large capacities ensure a highly versatile
production capability that will help you satisfy the quality needs
of your most demanding customers.
ECONOMY
A Low purchase price and inexpensive consumables make professional-quality
casting fro the small shop an affordable reality. You save time
and money with the J-2r IV- not only in the actual casting process, but also by reducing
casting rejects. The J-2r IV pays for itself in less time than you might think!
RELIABILITY
Heavy-duty, best-available components and solid engineering give
you a machine that will stand up to your most critical production
needs for many years to come. The J-2r IV offers the ebst return on investment you will find in a resistance-heated
casting machine.

OPERATION
The J-2r IV employs the proven principles of closed-system casting, providing
an oxygen-free atmosphere for the metal during melting and pouring
to help eliminate oxidation. The large-volume graphic crucible
also removes oxygen that may previously have been dissolved in
the metal. The means fewer defects and lower reject rates.

Keeping the metal oxide-free is one of the equation for successful
casting - another is accurate control of the temperature. The
J-2r IV measures the metal temperature in the centre of the metal pool,
giving you the accurate control of casting temperatures. The crucible
in the J-2r IV is a bottom-pour design so there is very little drop in metal
temperature from crucible to flask. This allows you to cast at
the optimum temperature for any design without overheating the
metal.
After initial warm-up, the casting cycle time of the J-2r IV is a fast 6 to 8 minutes, depending on the size of the load.
The large-volume crucible holds 902 grams (580 dwt.) og 14K gold,
or 722 grams (464 dwt.) of sterling silver. Flask sizes for the
machine can range from 2.5" to 4" in diameter and up to 9" high.
High-volume casting saves you money with less metal in process
and reduced material costs.
The J-2r IV is simple to install and operate, and no other resistance-heated
machine will perform as well in such a small area - only three
square feet of bench space.
Operating the J-2r IV, is simple
- set the temperature controller for the designed casting temperature,
- add the casting grain to the crucible,
- insert the flask, and at set temperature,
- push the casting lever.
- remove flask when pour is completed, remove flask
The J-2r IV. is an exceptional machine combining advanced technology with
a practical design to give you the casting capability you need
to now. The heavy-duty construction, with the best components available, offers outstanding reliability. As a NEUTEC
owner, you can depend on superb technical support and quick deliveries
of consumables to almost anywhere in the UK.
