Unique Advantages of the Process of Vacuum Pressure Casting Equipment
Process of vacuum pressure casting equipment:
Material pretreatment (Insert coated adhesive or semi-conductive rubber, filled vacuum drying, solid epoxy resin melting vacuum, curing agent vacuum)
→ Material mixing (Filling and epoxy first. The epoxy resin is vacuumed once and then mixed with the curing agent.
→ Pre-curing (The castable is solidified in the curing oven, the degree of cure is above 80%)
→ Release the mold (Maintain the proper temperature to unload the product and quickly load it) One mold)
→ Post-cure (Product solidification after demolding, increase curing degree, release internal stress)
→ Post-treatment (Cleaning product gate, mold seam and other defects)
→ Inspection packaging
Epoxy vacuum casting products have many unique advantages over traditional insulating materials:
1. No air gap or less air gap, the product has excellent electrical insulation performance;
2. Pouring molding has good fluidity, naturally filling the cavity, and the product has good uniformity;
3. Due to good electrical performance, the product can be miniaturized and the host structure is optimized;
4. Products can be made into complex shapes, and molded at one time, the integrity of metal inserts and insulating materials is good;
5. Weather resistance is good, can be applied to indoor and outdoor areas;
6. Products are solid, difficult to burn, safe and convenient to use.
But the process also has shortcomings:
1. There is no reinforcing material in the system, the mechanical properties are poor, and there is a break in the use of the host;
2. A certain stress is generated in the product, and the product has a risk of cracking when the stress is accumulated and released;
3. Appearance quality is prone to various defects.
