Long GF Impregnation Extrusion Line
Long Glass Fiber Reinforced Thermoplastic Composites Impregnation Extrusion Line
Long GF(Glass Fiber) Impregnation Extrusion Line (LFRT Extrusion Line)
Long glass fiber reinforced thermoplastic composites impregnation extrusion is superior to the traditional thermoplastic glass fiber reinforced production process. It is not simply coating fiber tows with polymer, inside impregnation mould individual filaments in the fiber tows are spread apart so each is encapsulated with thermoplastic polymer. The reinforced plastics produced by the long glass fiber impregnation extrusion process have better properties.
Long GF Impregnation Extrusion Line
Long-fiber Reinforced Thermoplastic (LFRT), the length of the glass fiber is bigger than 3mm.while the commercialized LFRT is normally 6-25mm.
Compared with common short glass fiber reinforced plastics, the flexural modulus of long glass fiber reinforced plastics has been increased by 2 times, the impact strength has been increased by 4 times, and it can remain unchanged at -30℃.
The excellent properties are as following:
*Non-orientation gridding structure enables it can keep the original property even in high/low temperature and high frequency environment.
*Excellent anti-impact, high modulus, high strength, low warping and similar thermal expansion factor with metal.
*Low shrinkage, low creep deformation, high dimensional stability.
*Excellent anti-wear and endurance.
*Excellent processing: high flow, easy demould, low damage to screw.
What Our Customers Have to Say
Llc Trans Business Logistics
Thank you for your support to our project. At the beginning of making the plan, the technical research and development team of Cowin patiently planned different plans for us to choose.During the production, keep us informed of the production progress.After the equipment was shipped to our factory, a professional team was dispatched to install and debug the equipment and train our staff.We are very grateful for this and look forward to our long-term cooperation next time.
Thanks for the hard work of Cowin team. Due to the large project, our company hopes to find suppliers with high cost performance and good quality in China.After the inspection of Cowin, we conveyed the design scheme to cowin. Thanks to the hard work of the design team for several months, the project can be carried out smoothly.After installation and debugging, the machine has met our expectations and we look forward to further cooperation in the future.
We received the machine on time. With the help of The After-sales team of COWIN, it has been installed and debugged and put into production, The performance and output of the machine are up to our requirements. Cross-border trade is not easy, but this cooperation has strengthened our interest to cooperate with Chinese manufacturers in the future. Despite the difficulties of the project, Cowin has a good attitude.
Your machine is great and the service is nice. Every time we cooperate with you, we are happy. Even under the influence of COVID, when we urgently need parts, our production is not affected, because you have provided us with sufficient spare parts inventory and delivered goods quickly. We are very grateful. For us, time is money.

Extensive Experience in Applications
The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by super-constant pigment uniformly attached to the resin, which can be called pigment concentration.
Compared with general plastics, engineering plastics can meet higher requirements in mechanical properties, durability, corrosion resistance, heat resistance and other aspects, and it is more convenient to process and can replace metal materials.
Filling masterbatch can be used to process plastic films, garbage bags, shopping bags, vest bags, packaging bags, etc. It has good dispersibility, blown film has no white spots and black spots, high fineness to guarantees product gloss and toughness.
Non-crystallization dry pet sheet extrusion has following advantage: Use in producing PET / PLA sheets , no need pre-drying crystallization of the energy consumption and adapt to the material for the production of the second , high yield , low energy consumption, high quality plastics characteristics.
