4. Equipment technical requirements and process flow

(Description of Process Flow for Gold Ingot Production Line)

4.1)Process description of gold ingot casting system:

The gold beads are manually weighed and placed in storage warehouses (8 storage devices). The storage devices automatically feed the gold beads into graphite molds. Vacuum heating and melting melt the gold beads into liquid gold. Vacuum crystallization molding is carried out. Gas protection cooling molds are used to push out the molds. The molds are automatically covered and the finished gold ingots are picked up by a robotic arm..

 

4.2)Process description for gold ingot cleaning, appearance scanning, coding, logo stamping, weighing, and palletizing system:

 

The finished gold ingots are transported to the cleaning station by a robotic arm - surface cleaning - the robotic arm sends the gold ingots to the drying device - drying is completed and the appearance is scanned - qualified products enter the pneumatic marking coding (or laser marking) - marking is completed and stamped LOGO - gold ingot weighing - gold ingot stacking, qualified products are transported to the pallet (unqualified products are picked up by the robotic arm and placed in the unqualified product station.

 

 

5. 1,Gold ingot casting system

Power Supply	380V/50Hz/three-phase five wire
Gold ingot casting efficiency	50KG/1 hour

 

Equipment dimensions	Approximately 6 meters (L) X 3 meters (W) X 1.8 meters (H)
Flameless tunnel furnace	It includes functions such as mold loading, conveying, heating (melting, nitrogen protection), crystallization, cooling, demolding, and mold placement, as well as supporting power supply and control cabinet (including touch PLC display screen). The temperature of the output ingot is less than 40C.
Gold ingot standard	The surface of the cast gold ingot is smooth, flat, without holes, shrinkage patterns, cracks, and rounded edges without defects. The product complies with GB/T 4135- The appearance standards of 2016 and the appearance requirements of LBMA London Gold and Silver Exchange can meet the registration requirements of the London Stock Exchange on a daily basis.
Loading and unloading system for molds	Using modules to transport and place molds, operated by an electronic pneumatic system with suction cups and angle rotating robotic arms at the mold station. The mold medium is high-purity graphite (During the automatic operation of the machine, one operator is required.) (The operator only needs to add gold beads at the machine workstation and remove the stacked gold ingots)
Automation requirements	)
Equipment control and protection	PLC and touch screen control, including equipment protection against overheating, overvoltage, underwater, and automatic protection against misoperation and personal injury.
The rack is made of (baked anti-corrosion paint) material
Corresponding intermediate frequency furnace and gold ingot crystallization cooling system
