Why GRAM Filament Winding Technology is Revolutionizing Industries

GRAM filament winding technology is a cutting-edge manufacturing process that has been gaining popularity in recent years due to its ability to improve the strength, durability, and overall performance of products. The technology involves winding continuous fibers around Sleeves to create a composite structure that is stronger and more stable than traditional materials.

In this article, we will explore the benefits of GRAM filament winding technology and how it is transforming various industries and companies.

Increased Strength

GRAM filament winding technology creates a stronger and more durable product, reducing the likelihood of damage during transportation and improving the longevity of the product. This is particularly beneficial for industries that produce products that are subject to harsh environments or high levels of stress.

Enhanced Durability

GRAM filament winding technology makes products more resistant to impact, weathering, and aging, improving their overall durability and longevity. This is particularly beneficial for industries such as transportation, where products are subject to heavy wear and tear.

Geometrical freedom and scalability

Geometrical freedom in producing GRAM filament winding technology has the ability to produce complex unique shapes, sizes, and designs in a component's manufacturing process. This is achieved through continuous fibers which are wound around pins or along a surface in a precise and controlled manner to produce a high-performance composite component. This process offers a greater level of design freedom compared to traditional manufacturing methods, allowing for the creation of components with intricate shapes, tailored stiffness and strength characteristics, and custom functional features. The GRAM filament winding technology, specifically, allows for a high level of automation, consistent quality, and increased productivity, making it an attractive option for a wide range of industries and applications.

Overall Goal

Investing in GRAM filament winding technology provides a competitive edge in the market and helps companies maintain their position as leaders in their respective industries. Whether you are in construction, transportation, or any other industry, GRAM filament winding technology can help you produce a superior product that will meet the demands of your customers.

In conclusion, GRAM filament winding technology is a game-changer in the manufacturing industry, offering numerous benefits that improve the strength, durability, and overall performance of products. If you are looking to stay ahead of the competition and provide a superior product to your customers, consider incorporating GRAM filament winding technology into your production process

Some Case Studies

Our Process to the customer

  • Here at Gradel LW we have a team to help identify which components and what materials can be used for your specific needs.

  • We then take the identified component and design something that is lighter, stronger, and friendly for the environment. Gradel LW prides itself with walking with the customer on each step to ensure the product is at its maximum potential. By utilizing computational power and strong engineering from all facets of design modeling.

  • Gradel has some of the best engineers from aerospace and mechanical backgrounds using some of the most sophisticated tools such as NASTRAN coupled with custom programs designed in-house. We walk you through the process and calculate your part down to the final fiber paths with a detailed report and findings.

  • When Gradel engineers a component for you, we want to stand by our calculations and design, using research facilities such as LIST (Luxembourg Institute of Science and Technology) located at the Gradel Compound to ensure the part is acceptable for use in your application.

  • After preliminary tests and quality, The customer has the option to produce in Gradels 600 sm space that can accommodate 40,000 units per year. The facility is rated for ISO 8 to applications for basic use.

  • If the Client wishes to make the part outside of Europe or to have production in larger volumes, Gradel offers the client to purchase custom machines for their specific needs. Making it easy to get the components you desire.

 
  • Pure winding

    This method is based on accumulating resin impregnated fiber to create “arm” like slim connections by winding around pins in the mold.

    The resin allows adherence and strength, as well as allowing flexibility. This process has the benefits of needing more economic tooling, fast production and providing a slim design.

    This parts can reach the strength of parts fabricated with carbon fiber sheets, while reducing weight exponentially.

  • Consolidated

    Consolidated parts are usually done by winding in molds with channels and pins, and compressing the piece afterwards. In this case the mix of resin and fiber creates a homogeneous distribution.

    This process creates smooth homogenous parts. Due to the requirements of the tooling and consolidation time, this process is recommended mainly for large scale production.

materials

  • Carbon

    or graphite fibers, this material has several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion.

  • basalt

    This material based on volcanic rocks melted in blast furnaces has the benefits of having good tensile strength, being non-toxic, resistant to UV, impact resistant, high temperature tolarance (-260 - 700 °C) and cheaper than carbon, kevlar and glass fibers.

  • Flax

    this plant based fiber is a sustainable alternative in composites. This fiber is biodegradable, cost effective and have good mechanical properties, high specific stiffness, easy processability, low density.

  • Glass

    fiber consists on fine fibers of glass. It has comparable mechanical properties to other fibers such as polymers and carbon fiber. When mixed with other products it becomes more rigid, very strong and lightweight.
