Pole Vacuum Casting Mould ，

• Hot work tool steel: such as H13 (4Cr5MoV1Si) and SKD61, suitable for most insulating materials with excellent high-temperature wear resistance and fatigue resistance.

• Special alloy steel: such as 3Cr2W8V or Y4 steel, suitable for high-melting point or corrosive insulating materials, ensuring mold stability under high temperature and pressure.

• Ceramic materials: used for high-precision, high-temperature insulation parts, but with higher brittleness and cost.

1. Sealing Design:

   • Mold parting surfaces require fluororubber seals

   • Ejector pins and gate sleeves must have clearance below 0.02mm to prevent vacuum leaks

   • Some molds use support columns to enhance rigidity and reduce parting surface deformation

2. Gating System Optimization:

   • Use multi-stage slender runners distributed along product contours

   • Increase gate width by 20%-30%

   • Set wide gate cross-section to reduce gas entrapment

3. Venting and Vacuum System:

   • Vent channels need to have "critical area" (related to casting volume and filling time)

   • Use M-type high vacuum valves or induction exhaust plates

   • Vent channel cross-sectional area should be more than 6 times that of traditional vent grooves

4. Cooling System:

   • Molds need uniform water cooling and oil temperature regulation channels

   • Mold temperature for thin-walled parts should be below 230°C to avoid deformation due to uneven cooling

• Electronic insulation parts: such as circuit board brackets and insulation covers, where vacuum die casting reduces internal porosity and improves insulation performance and voltage resistance.

• High-voltage equipment components: such as transformer insulation bushings and circuit breaker insulation housings, ensuring material density and preventing leakage or breakdown through vacuum process.

• New energy applications: used for battery insulation separators and motor insulation parts, meeting dual requirements of lightweight and high insulation performance.
