● O que é composto reforçado com fibra longa (LFT-G)?

O comprimento incluído da fibra reforçada é equivalente ao comprimento das partículas de plástico termoplástico maiores que 6 mm.

● What are the benefits of using LFT-G?

Benefits for business owners and factories:

a. Plastic instead of steel: The past metal material with high strength, heat resistance and other characteristics, is the preferred material for many industrial products, and the disadvantage is not suitable for forming complex shapes. Long glass fiber reinforced material (L.F.R.T) is the most similar to metal properties, seems to be the best choice to replace metal.

b. Lightweight: As the weight of general metal parts is relatively heavy, with the trend of environmental protection/energy saving in advanced countries around the world, the industry has started the trend of "lightening".

c. High strength mechanical properties: For the parts made of LFRT, long fibers form a three-dimensional 3D network structure inside, and cross through the matrix resin as a reinforced skeleton, so that the parts can withstand greater stress and load, and effectively absorb external impact energy, so that the finished products have excellent specific strength, rigidity, impact resistance, dimensional stability. And temperature resistance, low warping, creep resistance, low thermal expansion coefficient and other advantages.

● The use of LFT-G to contribute to environmental protection
Different from general thermosetting materials, LFT-G is a thermoplastic material, and its waste can be recycled and crushed, and reused or back mixed use, performance will not be significantly reduced, and can reduce the cost of disposal of waste in the latter section.

● What are the benefits of using LFT-G? What are the benefits for employees?
Compared to metal/thermosetting materials processing, LFT-G is a low VOC material and does not release any toxic substances.

● What are the advantages of LFT-G compared to other companies' products?
a. Computerized/automated Eurostandard original process unit, stable quality, excellent coating between resin and fiber.

B. the product variety, including PP, PA6, PA66, TPU, PA12, PPS, PPA, and other materials.

c. Dadong Technical service team will assist customers to deal with relevant issues in the whole process, such as specification suggestions, processing parameters, molds, product application, etc., to ensure that the performance of materials can meet customer requirements.

● What industries can LFT-G be used in?
It is suitable for automobile parts, hand tools, sports equipment (bicycle/ski/fishing tackle), shoe parts, industrial fans and other industries.

● Will it cost more to use LFT-G?

a. The unit price of materials is slightly higher than that of aluminum alloy, but it can save the cost/time of metal secondary processing, which is relatively favorable on the whole.
b. The unit price of materials is slightly higher than that of homogeneous staple fiber reinforced composites, but LFT-G has high dimensional stability and is not easy to deformation. It can be assembled after demoulding, which can save the cooling/pressure holding time of forming and the cost/time of fixing customized tools.

● Use LFT-G molding appearance will float fiber?
Datong resin selection of resin substrate is high mobility resin, the appearance of the finished product is good, if the mold temperature, the performance is better.

● Use LFT-G will wear more injection machine screw?
The wear screw is mainly the sharp cross section at both ends of the fiber. Long fiber and short fiber are two-point and one-line structure, but in the same proportion, the sharp cross-sectional area of short fiber is larger than that of long fiber, so the wear of the two on the screw is similar.
