Process automation
The furnace has automatic and manual operation functions. The furnace has a built-in computer. All casting cycle parameters can be corrected as needed. A total of 100 computer programming is available. 100 different types and combinations of alloys, colors, gold openings and castings can be specified. Each programming can be recorded with a name or number for easy selection. The MCE series has been programmed in its built-in computer for computer programming of the most popular castings and gold counts.
Intermediate frequency generator
The induced current heats the metal, and the alloy automatically generates a thermal effect until the casting is completed, and finally a completely homogeneous casting is produced. In addition, pre-early casting of the alloy in individual furnaces can be avoided. According to the manufacturer, the core of the IF converter consists of a microprocessor that automatically recognizes the various types and quantities of alloys and automatically adjusts to output maximum energy. If å©åŸš gradually degrades and loses enamel, the computer will prompt for replacement, so that the machine can exert maximum energy and power.
Measuring temperature
An N-type thermocouple thermometer is embedded in the valve to measure the temperature of the alloy.
Inert gas protection During the melting, homogenization and casting process, the surrounding environment is protected by an inert gas (argon or nitrogen). A micro switch is placed on the cover to activate the electromagnetic cutting, which in turn causes the inert gas to flow into the crucible. The surrounding inert gas protects the metal during casting from oxidation.
Put into the mold / mold cup
Once the casting temperature is reached, the computer prompts the user to place the heat-resistant mold. Before the casting and after the casting is completed, the two pneumatic jacks of the lower furnace chamber lower and raise the mold.
Casting stage
Two different programming controls are available: 1. Use a non-bumped or non-porous mold cup: using argon or pure hydrogen gas, the pressure adjustment range is from 0.1 to 1 bar. 2. Use flanged and perforated mold cups: use argon or pure hydrogen gas, pressure adjustment range from 0.1 to 2 bar.
Solidification stage
The inert gas flows from the upper layer of the furnace chamber to the lower layer, increasing the effect of the alloy pressing into the mold. At the same time, it is possible to avoid oxidation during the solidification phase.
During the cooling phase, the upper and lower furnace chambers are separated when the flap is closed. At this time, the mold cylinder is cooled in an atmosphere filled with an inert gas, and when the mold cup is still cooled in the lower layer, the upper layer can be filled with more alloy and can be melted. This overlapping treatment can shorten the cycle time. For example, 2 kg of 18 ct gold can be shortened by about 6 minutes. The MCE series' newly designed cooling system allows the machine to operate 24 hours a day.
Productivity and cost
MCE series products can accommodate a variety of mold cups. The flanged cup is up to 150 mm x 300 mm high; the maximum without flange is 120 mm x 300 mm.
Brief Introduction & Working Principle
when compressed air enter into the vacuum pump, simultaneously under the push of air cylinder, the empty door of hopper will be closed and the vacuum will be formed in the hopper. The vacuum feeding machine forms air stream under vacuum state. Under the action of this air steam the material which is conveyed will be transported to vacuum hopper through hose. Certain time later (feeding time, adjustable), the compressed air is closed, the pneumatic vacuum pump is unable to produce vacuum, simultaneously under the push of air cylinder the emptying door of hopper will be opened and the vacuum will be disappeared in the vacuum feeder. The material will be fed into receiving equipment from the emptying door (for example tablet press, packing machine and so on), simultaneously, compressed air that stores up in air packet's blowback the filter, and the filter cleans by itself. Certain time late (discharging time, adjustable), the compressed air starts again. Move in cycles, the material is fed into the equipment continuously.
The machine is well designed and produced, consisted of vacuum pump (non-oil & non-water), stainless-steel-made product sucking mouth, feeding tube, cloth filter (or 316 stainless steel filter), vibration cleaner (or compressed air blower), vacuum product hopper and product level control system. There are some different between when machine combined with packaging machine, pellet pressing machine and Mixing Machine respectively.
