Feature #   Advantages & Benefits -- Intellijector® vs. Yasui®
1   The Intellijector® stores six critical parameters of each mold in its memory including injection temperature, injection pressure, injection time, clamp pressure, forward pressure, and dwell time.  Keying in the mold number recalls these parameters and sets the machine for injection.  The Intellijector® can store the parameters for over 3100 individual molds and up to 99 groups of molds.
2   The mold clamps use a positioning sensor to ensure repeatable results to within .001-inch (.025mm).  This means change in air pressure or wear in the clamp piston will not affect the finished wax.  Mechanical regulators vary up to 15% and do not insure repeatability; even at the same setting.
3   Forward pressure is controlled using a special low stiction piston and digitally controlled air pressure accurate to within 0.1 psi (.689 Pa) of the setting.  Mechanical regulator can't even come close to this accuracy.
4   The nozzle is part of a high-speed heat exchanger that can rapidly heat or cool the next shot of wax to match the molds' requirements.  No time is lost waiting for it to cool down on its' own.
5   Direct digital temperature input means accurate settings for repeatable results.  Analog dial setting are only approximate.
6   The on-board computer monitors vacuum levels to make sure the next step proceeds only if vacuum levels are correct.  A simple timer is no measure of vacuum.

7   In shops with no vacuum available, the Intellijector® will produce its' own vacuum from shop air.  An external vacuum pump is an option.
8   Injection time is set by the mold database in 0.1 sec. increments and is accurate to 20 ms.  Again, an analog dial setting is only approximate.
9   Wax pressure is set by the mold database in 1 psi increments and is accurate to 0.1 psi (689 Pa).  One number calls up and sets all injection parameters, not just the pot pressure setting.
10   Cooling time is entered in the mold database in 1 sec. increments.
11   The Intellijector® provides separate plumbing for mold vacuum and wax injection.  Since the entire mold is put under vacuum, there is no need to use the same path as the wax.  This eliminates the need of a "trash pot" and keeps air from being drawn into the injection nozzle and producing bubbles.  The patented Wilcox Clamp ensures vacuum inside and outside the mold.
12   On the front of the Intellijector® are two vertical progress displays that show the status of each clamp.  Each segment is labeled and lights with the current step of the cycle.  Combined with the countdown display on the main screen, there is never any doubt as to what the machine is doing.

13   Also located on the front are the diagnostic LED's which, when compared to the status bars, will allow most any problem to be resolved.  No need to have a technician opening the case in order to troubleshoot.
14   In the event of a mold misalignment or sprue hole leak, the Intellijector® will detect it, shut off the wax flow, and alert the operator.
15   A built-in 7 day heat timer allows for different shift times.  This means the wax is melted and the machine is ready for your operator.  This also means longer wax life, reduced power usage, and fewer cleanings because the heaters are off when not in use.
16   The automated shift start pre-vacuums the wax pot to remove air and moisture before injection.
17   A well insulated wax pot reduces power usage, helps stabilize wax temperatures, and keeps the heat away from the operator.
18   Programs are clearly displayed on the large, illuminated, high contrast LCD display for review and making changes.
19   The Intellijector® is available in English, Spanish, Italian, Turkish and Portuguese.

20   The central control panel allows all adjustments to made in one location.  There are no obscure control knobs, dials, or switches spread around the machine.
21   The operator receives plain language instructions from the display when needed.
22   The Intellijector® has exclusive, inherent safety factors.  The nozzle is aimed away from the operator at a right angle to the front of the machine and the wax is under vacuum throughout normal operation.  This means no hot wax can be ejected toward the operator or anyone else!
