Why do we need waste PA airbag recycling?

As the base fabric of the airbag assembled in the airbag device, there is a fabric (uncoated base fabric) woven (usually plain woven) made of PA fiber threads (for example, nylon 66), and one or both sides of the fabric There are two types of coated fabrics (coated base fabrics) that form elastic coating films.

Waste materials of airbag base fabrics (including scraps generated when cutting the base fabrics. The same applies below) are generated in large quantities. There are increasing demands for recycling (reusing) base fabric waste as PA recycled materials.

Since the uncoated base fabric is composed only of PA fiber threads and is easy to regenerate, its recycling has been put into practical use.

PA airbag shredder in PA airbag waste recycling

The complexity of PA airbag recycling challenges. To protect vehicle occupants in an accident, PA airbags are extremely tear-resistant and therefore difficult to shred. We recommend you use a twin-shaft shredder.

PA airbag waste shredder is also popular as dual-motor dual shear shredder, featuring with very high shredding output due to its double motor configuration. Attributed to the two rotary cutting shafts with resistant knives, this type of shredder is capable of shredding almost all cuttable materials. The two cutting rotors powerfully grab the feed material. No matter the feed material is e.g. large piece of hard plastic or heavy tires, this PA airbag waste shredder machine can easily shred PA airbag waste into small pieces.

Wherever the toughest conditions exist in solid waste recycling operation, this twin shaft shredder is found in action. Controlled by PLC system, this two-shaft shredder can work in an automatic mode including automatic start, automatic stop, and automatic reverse in the condition of overload, which greatly reduces labor and meanwhile generates high efficiency.

How to recycle PA airbag waste?

Before the actual recycling process, the delivered plastic waste is checked for impurities and foreign matter and, if necessary, pre-sorted according to type. By doing this, the purity and high quality of PA air bag waste recycling and re-granulation can be guaranteed.

PA air bag waste is sent to the hopper through the conveying system. After shredding, a conveyor belt with an integrated magnetic drum for FE impurity separation discharges the shredded material from the machine onto the feed belt of the extrusion line. There, the material is melted, homogenized and, if necessary, degassed. The molten plastic is cooled into strips in a water bath, cut into the desired particle size, and dried. The resulting re-granulation can eventually be returned to the raw material cycle. As a result, the proportion of new plastic in production can be significantly reduced and replaced with new plastic.

Waste PA Airbag Recycling Shredder Blade：

Waste PA Airbag Recycling Shredder Machine Working principle：
PA airbag waste shredder is to cut and shred the materials through the relative rotating of the two sets of cutter shafts, the mutual shearing among the blades of moving knives & the cutter heads and the distance sleeves. The outlet-material control of double-shaft PA airbag waste is adopted the network design, the width and length of outlet-material are determined on the width of the cutter, and the distance of cutter heads. Two groups of cutter shafts rotate at different speeds which leads to the shearing and shredding of materials simultaneously, it improves the efficiency of shredding.

Waste PA Airbag Recycling Shredder Machine Components:

Shredder Chassis The whole chassis is made of welded steel plate and finely machined by CNC gantry milling, which has high bearing capacity, high impact resistance and more stable quality.	Shredder Spindle The shredder spindle is made of high alloy, forged and heat-treated and tempered as a whole, and then machined into hexagonal, octagonal and spline form by CNC gantry milling after fine turning, with long service life.
Shredder Blade The shredder blade is made of special steel, forged, faded, refined, vacuum heat treatment, computerized wire cutting, CNC grinding machine processing.	Segmented Blades The segmented blade design can greatly reduce the blade changing time and cost. The blade comprises of the blade holder, and two types of blade segments, with and without hooks. Worn blade segments can quickly and easily be removed and replaced by simply removing the securing screws.
Motor The motor adopts Siemens, Wanan and other domestic brands of pure copper motor, with stable and reliable quality, and can be customized according to requirements.	Planetary Reducer The reducer chassis adopts welded box, helical gear, planetary gear transmission, with small volume, low noise, high torque and other characteristics, higher transmission efficiency.
Belt Conveyor(Optional) The waste is conveyed into the shredder through the belt feeding device, and the speed of the conveyor belt is automatically adjusted according to the current of the shredder.	Electronic Control The whole model adopts frequency conversion control and conforms to international standards such as CE/CSA.
