Automatic pressure Gelation Process

APG process (Automatic Pressure Gelation Process referred to as the APG process) was first filed a patent on June *9, ***9 by Ciba-Geigy, Switzerland. In China, with the development of pressure gelation equipment and its continuous improvement under the Coal Research Institute, as well as the gap between local epoxy resin specialized for pressure gel and imported material increasingly narrow, pressure gelation process in the electrical insulation industry has also been expanded, and has played an irreplaceable role. Pressure gelation technology is now successfully used in the production of high quality enclosed pole, cross-fluorinated sulfur load switch housing, transformers and other products.

Pressure gel process to produce the insulators as outlined below:
1. Material pretreatment
A certain percentage of epoxy resin speical for pressure gel, curing agent, fillers, colorants join the mixing tank. Stir 1 to 2 hours to mix material evenly and no bubbles in the sealed pot under a vacuum state (absolute pressure is less than **0Pa).
2. Injecting, forming
Pretreated epoxy resin mixture is injected into the APG mold preheating to **0deg with the help of compressed air or pressurized pump. The mixture is released from the mold after thermal gel forming and get semi-finished products.
APG mold should be set aside suitable gap in a specific parting line surface in order to discharge the air from the mold in the process of injecting material. After the gel injecting into the mold, the epoxy resin due to rapid heating fill into the small gap, leaving the mold in a sealed state, so the material within the mold under pressure gradually gel to get a close texture product. In order to make the mold parting line surface leaving some gap not only able to exhaust but also reliable seal, which require higher accuracy of the mold, especially for some of the complex structure of the insulators, the mold is with much higher accuracy requirements. In short, Pressure gel mold is equipped with a high technical content.
3 . Curing
After injection, the products are transferred to the oven, and the finished products get dense and low internal stress after slow cooling under constant temperature of **0deg *0 hours.

This company produces the APG equipment has the following several advantages:

1, the only one at the same time the APG manufacturing equipment and APG pressure injection mould, equipment and mold better coordination, to ensure that product qualification. 
2, the only company with domestic transformer product testing equipment manufacturer, product compression, partial discharge test equipment, as required in our trial production of qualified products, in the shipment. 
, have rich experience of transformer production technology teacher, for your company provide free technology training, and help customers qualified products. 
4, specially designed for transformer of thin film degassing mixing device, greatly improving the uniformity of mixing and pumping vacuum material. 
5, Combination of equipment, moulds, as well as under the engineers constantly summarize and improve the production equipment has superior performance, high efficiency energy saving etc.
6.By APG pressure gel molding process, greatly improving the production efficiency, increased the product surface bright and clean degree, reduce the mold cost, reduces the labor costs of inputs.
7.We can customize machine according to customer's needs.
