Replacing steel with plastic is the most important way to lighten cars at the present stage. Replacing metal with plastic, for example, modifying PA,PA6,PP and other materials with long fibers.LFT-G modified PP has good mechanical properties, small density, chemical corrosion resistance and other characteristics. According to relevant statistics, the amount of modified PP materials used in automobiles accounts for about 50% of the plastics used in automobiles.The long fiber modified PP material is one of the most commonly used automotive interior materials.It is often used to make instrument panels, door panels and other interior decoration, but the surface of the scratch resistance is poor.The addition of fiber or filler with spherical microstructure (such as talcum powder, silica silica powder, glass beads, etc.) can improve the hardness and modulus of the modified polypropylene PP, and improve the scratch resistance to a certain extent. The high strength performance of PP modified materials can ensure the collision resistance of cars and reduce losses and costs.With the advancement of automobile production technology and the production of modified materials, the combination of long fiber modified materials and high strength steel can be used in the roof beam column, front beam column, threshold beam, C column, etc.This can increase the torsional stiffness of the body and reduce the weight of the body. In addition, long fiber modified PP material is also widely used in wheel hub, brake system, transmission system, interior and exterior decoration, engine field. Benefits of the application of LFT-G in the automotive industry: 1. High integration: a part can integrate a variety of functions, reduce the cost of the mold and processing molding time; 2. Manufacturing process optimization: compact structure, reduce installation steps, easy assembly, easy installation, disassembly and maintenance; 3. Corrosion resistance: the whole body is corrosion-resistant, which can meet the requirements of corrosion resistance.

Polypropylene PP is one of the most common plastics known as food grade plastics.The application range of PP material is also very large, such as food packaging, plastic cups, small home appliances, auto parts and so on.Today we will understand the new application of modified polypropylene PP in the medical industry! First of all, why is it necessary to modify polypropylene PP? PP itself has many advantages, but at the same time in anti-aging, low temperature resistance, impact resistance and other properties, not good enough.As a kind of engineering plastics, PP modification, so that the material to overcome its own shortcomings, improve its performance to achieve the use of a wider range of conditions. Secondly, understand the application of modified LFT-G polypropylene PP in medical treatment It is reported that the modified LFT-G polypropylene PP is used in the Nordic chemical and Boru Healthcare fields, customers in the production of pipette and other medical and diagnostic equipment can fully comply with the regulations and development.The new product guarantees users a safe and long-term supply of materials that comply with European and American pharmacopoeia and ISO standards. In addition, the modified PP product has also been verified and can obtain relevant patents in the future.The LFT-G material also has the following advantages: First, improve the impact resistance, which can not only reduce the probability of breaking equipment, but also let such as refrigerators, deep cold storage and low temperature equipment with good decline performance. Second, it has high liquidity, which can make the production process more convenient and shorten the time. Website:www.lft-g.com Contact:sale04@lfrtplastic.com

PA nylon pellets is a kind of engineering plastic with excellent properties, such as good mechanical properties, good corrosion resistance, excellent heat resistance and high modulus.Long glass fiber reinforced and flame retardant polyamide additives can significantly improve the heat resistance, modulus dimensional stability and flame retardant of Polyamide. Long glass fiber PA12 is widely used in automobile, power tools, electronic machinery and other industries. The characteristics and processing technology of nylon PA12 long glass fiber reinforced thermoplastic modified plastics. When 30% long glass fiber is added into PA, the mechanical properties, dimensional stability, heat resistance and aging resistance of PA12 can be significantly improved, and the fatigue strength can be increased significantly. Long glass fiber reinforced PA12 molding process of injection molding process, because of the glass fiber will be along the flow direction orientation in injection molding process, mechanical properties and shrinkage caused by strengthening, in the direction of orientation lead to products deformed, therefore, mold design, gate location, shape, reasonable, craft can increase the temperature of the mold, the product comes out in the hot water allow it to cool down slowly.In addition, the larger the proportion of adding fiberglass, the larger the wear of the plastic components of the injection molding machine, it is best to use a single metal screw injection molding machine, the performance of the long glass fiber will be better.

Applications in the airplane filed PEEK long carbon fiber composite has advantages of low density and good processing ability, which is convenient for direct processing into high-demand parts. The long carbon fiber reinforced PEEK composite material further enhances the overall performance of polyether ether ketone, so it is increasingly used in aircraft manufacturing.For example, the fairing used in Boeing's 757-200 series aircraft is made from a carbon-fiber reinforced PEEK material. Applications in the automotive field Vehicle energy consumption is closely related to vehicle weight.Vehicle lightweight can not only reduce fuel consumption and exhaust emissions, but also improve power performance and safety.The use of lightweight materials is the most direct method of vehicle lightening.Carbon fiber reinforced polyether-ether-ketone PEEK composite material has great potential. Plastic can be used instead of steel. It has advantages of low density, good performance and convenient technology.For example, in the Enterprise Robert Bosch GmbH, carbon-fiber reinforced PEEK has replaced metal as a functional component of ABS.The lighter composite parts reduce inertia and minimize reaction times, thus greatly improving the response performance of the entire system and reducing costs.

With the continuous growth of the plastics industry, the market demand for plastics is getting higher and higher. In the production process of the product, the pa66 raw material of our Xiamen LFT composite plastic Co., Ltd. is added with long fiber, which is suitable for injection and extrusion processes. So what details should be paid attention to in the injection molding process of long fiber pa66? Consider the drying problem: the package is completely sealed and usually does not require drying. If there is slight humidity, it is recommended to dry in hot air at 80 °c. Melt temperature: 270 ~ 299 °c. Special additives require additional adjustment of the actual temperature. Mold temperature: It is recommended to be between 66 °c and 124 °c. The mold temperature will affect the crystallinity and effect of the finished product, and the crystallinity will affect the physical properties of the finished product. Adjust according to the mold structure. Injection pressure: usually between 34-124mpa, depending on the product structure, injection port position, injection temperature and other conditions. Runner and gate: It is best to use a hot runner. The rubber port should be larger without a hot runner, and vice versa. Other methods can refer to our technology. Pa66 has a higher melting point in polyamides, and can still maintain strong strength and rigidity at higher temperatures after modification. It should be noted that pa66 still has water absorption after molding, which should be noted in the selection of the use environment.
