Product Specification

Vacuum Pressure Impregnation Equipment Porous Leak Sealing for Automotive Parts D600 * 700H

1. General Introduction

Vacuum impregnation technology is a proven solution to solve leakage problems in castings. This technology pressurizes sealants into the porosities of castings, curing them to create airtight components capable of containing liquids or gases. Vacuum impregnation is widely used in industries such as military, automotive, shipbuilding, and aerospace, offering the most reliable solution for repairing porous castings.

Our vacuum impregnation equipment is designed for leak repair of castings, sealing powder metal products after sintering, improving the insulation properties of electrical components, and pretreating castings before processes like galvanizing and plating. This equipment is particularly effective for aluminum, magnesium, and copper alloy castings, enhancing their airtightness and durability for demanding applications.

2. Vacuum Impregnation Process

The vacuum impregnation process involves multiple steps that ensure comprehensive sealing of defects in casting parts:

1. Vacuum Impregnation: The process begins by placing castings in the impregnation tank, followed by vacuum suction to remove air from the casting pores.

2. Centrifugal Drying: After impregnation, a centrifugal dryer removes excess sealant from the surfaces.

3. Washing: The castings undergo two stages of washing to eliminate any remaining sealant.

4. Hot Water Curing: Finally, the parts are cured in a hot water tank at a controlled temperature to solidify the sealant.

Detailed Working Procedure:

• Preparation: Place clean components into a workpiece basket.

• Impregnation Tank:

  • The basket is lifted into the impregnation tank.

  • Vacuum pressure of -0.099 MPa is applied for 5 minutes.

  • Sealant liquid is added, and the parts are impregnated under 0.4 MPa for another 5 minutes.

  • Excess sealant is returned to the storage tank.

• Centrifugal Dryer: The workpieces are rotated for 3 minutes to remove excess sealant.

• Wash Tanks I & II: The castings are cleaned in two separate wash tanks using pneumatic mixing.

• Hot Water Cure: Finally, the castings are placed in the hot water cure tank at 90°C for 15 minutes.

3. Equipment Configuration

Our vacuum impregnation system is designed for optimal performance, featuring robust and efficient components:
