1.Raw materials should be selected
Factors affecting the quality of high-voltage porcelain dielectric capacitors, in addition to the composition of porcelain materials, optimize the process of manufacturing, safety capacitor manufacturers strict process conditions is very important. Therefore, the raw materials should be considered both cost and purity, and when choosing industrial pure raw materials, we must pay attention to the applicability of raw materials.
2. Preparation of molten block
The quality of the preparation of the molten block has a great impact on the fineness of ball milling and firing of porcelain, such as low synthesis temperature of the molten block, the synthesis is not sufficient. The subsequent process is not conducive. Such as synthetic material residual Ca2+, will hinder the rolling film process: such as synthesis temperature is high, so that the frit is too hard, will affect the ball milling efficiency: the introduction of impurities in the grinding medium will reduce the powder activity, resulting in the firing temperature of porcelain parts.

3. Forming process
厚さ方向の圧力ムラを防ぐために成形し、ブランクの閉じた孔が多すぎると、発生した大きな孔や層の亀裂がある場合は、磁器本体の電気強度に影響を与えます。
4. Firing process
焼成システムを厳密に制御し、温度制御装置の優れた性能とキルン設備の良好な熱伝導性を取る必要があります。
5. Encapsulation
The choice of sealing material, the control of sealing process and the clean treatment of the surface of the porcelain parts have great influence on the characteristics of the capacitor. Ok this, must choose good moisture resistance, and porcelain body surface closely combined, high electrical strength of the package sealing material. At present, most of the choice of epoxy resin, a few products also have the choice of phenolic resin for sealing. There are also taken first insulating paint coating, and then the phenolic resin encapsulation method, which has some significance to reduce costs. Most of the large-scale production lines use powder encapsulation technology.
