Application of LFT mould in automotive industry

Join Date: 2022-03-22

LFT moulding - long fiber reinforced thermoplastic materials, it is compared with the ordinary fiber reinforced thermoplastic materials, usually, fiber reinforced thermoplastic materials in the fiber length is less than 1 mm, LFT moulding, the length of the fiber generally greater than 2 mm, the processing technology, has been able to keep the fiber length in LFT moulding over 5 mm. Depending on the end use, the finished product can be strip, strip, board of a certain width, or even rod shaped, directly used in place of thermosetting products.

Long fiber reinforced thermoplastics (LFT moulding) have been used in the automotive industry for semi-structural applications. Their main advantages are attractive cost, performance ratio and relatively low density. In the automotive industry, LFT mould is mainly used to make structural and semi-structural components, such as front-end modules, bumper girders, instrument panel frame, battery bracket, spare tire bin, seat frame, pedal and integral floor, etc. Long fiber reinforced polypropylene is used in the car hood, instrument panel frame, battery bracket, seat frame, car front-end module, bumper, luggage rack, spare placenta, fender, fan blade, engine chassis, car roof lining, etc.; Long fiber reinforced PA is further extended into the hood, because tfT-PA is not only hard, low weight, and high glass fiber content makes its thermal expansion coefficient almost the same as metal, can withstand the heat brought by the engine.

Apart from their economic appeal, their main advantage is the flexibility with which materials can be mixed. Continuous variable fiber content and different types of fibers, combined with engineered plastics, open up potential applications.

Dacheng mould is engaged in the design and manufacture of composite mould and has developed many LFT mould products. As an LFT mold supplier of automobile factory, Dacheng Mold has many years of research in LFT mold design and LFT mold process, and has a supporting LFT mold test line, to ensure that LFT mold from the initial design to the subsequent mass production to meet the needs of customers.
