introduction to bag forming technology 0509

pbf (pre press air bag forming) is a high-quality and highly applicable composite material forming process. the typical step of this process is to fill the interior of the airbag with high-pressure gas to apply uniform pressure to the layer material, and heat and solidify it using methods such as a hot press and oven.

technical advantages

01、especially suitable for forming products with irregular cavity structures that are difficult to achieve in general processes;

02、the molding pressure can be adjusted with a large amplitude, and the pressure uniformity is comparable to that of the hot pressing tank process, resulting in good surface quality of the product;

03、can be combined with multiple processes, with wide applicability;

the tail wing product is formed as a whole using a combination of air bag technology and hot pressing tank technology, and has the following characteristics:

technical features 01

integrated manufacturing of cavity structure tail wing products using airbag method;

technical features 02

using hot press tank equipment to ensure temperature uniformity;

technical features 03

perform a vacuum pumping step on the prepreg side to further reduce product porosity, improve product performance and surface quality;
