Analysis of Advantages of Vacuum Pressure Casting Technology

Compared with traditional casting methods, vacuum pressure casting technology has significant advantages in the field of jewelry manufacturing, mainly reflected in the quality and process control of castings.

Excellent casting quality

High density: Smelted under inert gas protection, combined with vacuum degassing and instant high-pressure injection, the metal liquid has extremely strong filling ability, and the internal structure of the casting is dense, effectively eliminating defects such as sand holes, bubbles, and shrinkage cavities.

Excellent surface quality: The casting has a high surface finish and is basically free of oxidation, which can greatly reduce the workload of subsequent polishing and finishing.

Integrated design of equipment

Modern equipment commonly adopts a dual cylinder design that integrates the melting chamber and casting chamber, with a compact structure and small footprint.

Equipped with comprehensive temperature, pressure, and vacuum alarm systems, ensuring high operational safety.

Comparison with centrifugal casting

Vacuum centrifugal casting relies on centrifugal force to form and is suitable for symmetrical parts with minimal metal residue.

Vacuum pressure casting uses external active pressure to achieve better filling effect and stronger process controllability for workpieces with complex structures, rich details, and large wall thickness differences. It is currently the mainstream technology for precision jewelry casting

Equipment maintenance and long-term upgrade strategy

To ensure optimal performance throughout the device lifecycle and extend its service life, a systematic maintenance and upgrade plan needs to be established.

Preventive maintenance system

Regular inspection and maintenance: Develop a maintenance plan and regularly inspect the vacuum pump, sealing system, heating coil, electrical connections, and various sensors.

Establish operational records: Detailed records of equipment operating time, process parameters, faults, and maintenance history to achieve traceable management.

Utilize warranty services: The equipment usually comes with a one-year warranty for the entire machine, with the same warranty for core components. The supplier's technical support should be fully utilized.

Technological upgrade path

Software upgrade: By updating the control system software, the process curve can be optimized, control accuracy and automation level can be improved.

Hardware transformation and addition: In the future, it may be considered to integrate modules such as automatic weighing and feeding systems, intelligent preheating devices for molds, or visual inspection systems, gradually upgrading to intelligent manufacturing.
