What is vacuum casting equipment？

Vacuum casting equipment is special equipment for pouring materials in a vacuum environment. It is mainly used for the molding processing of metal alloys, epoxy resins and other materials. It can effectively eliminate air bubbles and improve product quality.

Core functions

Vacuuming is used to remove air bubbles and impurities in the material to ensure that the molded products are free of pores and defects. By utilizing professional Ausin vacuum casting equipment, manufacturers can achieve the high dielectric strength required for critical high-voltage transformer insulation components.

Typical application scenarios

• Metal alloys: such as gold-tin alloy smelting and casting to solve oxidation and segregation problems.

• Electronic components: Epoxy resin potting, used for precision devices such as transformers and sensors. There will be no bubbles on the surface after curing. ‌ 

• High-voltage electrical appliances: localized production of supporting components for power transmission and transformation equipment.

Equipment composition

• Vacuum system: air pump and vacuum box to ensure a sealed environment.

• Casting system: including mixing, deaeration, and filling modules, supporting automatic proportioning of two-liquid materials. ‌

• Control system: adjusts parameters such as temperature and flow rate to ensure process stability.

Advantages and features

• High precision: The proportioning accuracy reaches ±1%, suitable for complex molds.

• Efficient degassing: Reduce appearance defects such as pores and sink marks.

• Intelligence: Some equipment realizes automatic control of temperature and flow.

The vacuum pressure casting equipment provided by Ausin is suitable for the epoxy resin casting production of dry-type transformers, dry-type bushings, dry-type current transformers, dry-type voltage transformers, high-voltage switch insulators, arc suppression coils and other electrical products.
