Are you looking for a filament winding machine? Having trouble deciding what type, materials, and software to use? Below you will find our small guide to help you select the right machine. This article discusses the process itself and the key factors to consider before making a significant decision.<\/p><\/blockquote><\/figure>\n\n\n\n

<\/div>\n\n\n\n

A brief overview of filament winding<\/strong><\/h3>\n\n\n\n

Filament winding is a complex and precise manufacturing process where continuous fibers are impregnated with resin and wound onto a mandrel to produce tanks, pipes, pressure vessels, and other round-form products that require a high degree of structural integrity. This process is used to make tubular parts like rocket bodies, pressure vessels such as compressed air or gas tanks, suspension components in auto racing, and even refueling aircraft in flight. Its ability to adapt to changing fiber orientations makes it ideal for creating custom lightweight composite structures engineered to target different strengths.<\/p>\n\n\n\n

Key factors for your decision<\/strong><\/h3>\n\n\n\n

Now that you know about the technology, the next step is to consider the important buying factors. Here are some key points to keep in mind:<\/p>\n\n\n\n

<\/div>\n\n\n\n
\n

Purpose and Application<\/strong><\/p>\n\n\n\n

Determine the specific purpose for which you need the filament winding machine. Understand the application requirements, such as the type of products you intend to manufacture, the materials you’ll be using, and the production volumes you expect. This will help you select a machine that aligns with your specific needs.<\/p>\n\n\n\n

For example, if you need large capacity production output for CNG, H2, or LPG tanks probably you should consider a multi-spindle filament winding machine<\/strong>. It can wind from 2 up to 5 spindles simultaneously. In automated filament winding lines, if you want to be more economical and have fast operator interactions, you use pneumatically driven chucks for an automatic clamping system.<\/em> Also, these multi-spindle machines have a double-drive carriage system that ensures the stability and the movement of the carriage axis is increased, and any shaking of the delivery eyes is eliminated. If you need a machine for product development where you can run different trials, you probably need a single spindle portal configuration.<\/strong><\/em> <\/p>\n\n\n\n

Machine Specifications<\/strong><\/p>\n\n\n\n

Consider the technical specifications of the filament winding machine. Pay attention to parameters like the maximum winding diameter, maximum length, number of axes, winding speed, and tension control capabilities. Ensure that the machine specifications meet your production requirements and are compatible with the materials you plan to use.<\/p>\n\n\n\n

For example, if you need to produce large composite parts up to 4m in diameter, you need Floor-bed and a heavy-duty unit.<\/strong> If you use towpreg material, you probably need 5 axes of control, for complex parts you may need more, like 6 axes of motion. Towpreg can be up to 2.5 times faster than wet filament winding. Winding speed can be over 5 meters per second, and a wide range of winding angles is possible. If you want to reduce operator interaction more, Mikrosam provides also its own patented and proven technology for automated starting, cutting, and restarting (CRS)<\/strong> of fibers on the winding program. <\/em><\/p>\n<\/div><\/div>\n\n\n\n

\n

Material Compatibility<\/strong><\/p>\n\n\n\n

Filament winding machines can work with a variety of materials, including carbon fiber, fiberglass, Kevlar, and other composite materials. Verify that the machine you’re considering can handle the specific materials you intend to work with effectively. It should have the necessary features, such as resin delivery systems, to accommodate your materials.<\/p>\n\n\n\n

For example, the first thing you should know is do you want a wet or dry (towpreg) winding machine. If you need a wet filament winding machine<\/strong>, you need a resin impregnation bath possibly with a resin mixing system for high automation.<\/strong><\/em> On the other hand, towpreg winding process requires special adjustments to the fiber creel and delivery eye. Compared to traditional wet filament winding, the towpreg process can make the workplace cleaner, as there is no wet resin, and safer, as prepreg exhibits little to no emission of volatile off-gassing compounds (VOCs), and thus does not expose operators to hazardous volatile chemicals. For multi-spindle machines, our resin baths have a programmable doctor blade<\/strong> for the resin pick-up set. Mikrosam solution provides that each of the fiber tapes that goes to different spindles can have individual and programmable resin pick-up adjustment. This is very important for the quality of the process, especially where each spindle has a different angle of the fibers coming from the resin bath.<\/em><\/p>\n<\/div>

Automation and Control<\/strong><\/p>\n\n\n\n

Determine the level of automation and control required for your production process. Some machines offer manual control, while others are equipped with advanced automation features. Consider factors like ease of programming, operator interface, and the ability to customize winding patterns. Depending on your needs, you may opt for a more automated machine or one that allows for greater manual control. A Mikrosam machine comes with its own software, so no third-party software is required.<\/p>\n\n\n\n

For example, WindingExpert<\/a> <\/strong>is a software solution developed by Mikrosam that is used for the Pattern Generation of our Filament Winding machines.<\/em> The software can generate a mandrel model, which is used to calculate fiber paths and winding patterns. Besides that, it provides a lot of amazing features like Cad and Excel mandrel import, a user-friendly interface, material and thickness reports, mandrel volume calculator, burst pressure calculator, G Code import, ISO standard, and support for different types of controllers. <\/em><\/p>\n<\/div><\/div>\n\n\n\n

\n

Production Capacity<\/strong><\/p>\n\n\n\n

Evaluate the production capacity of the machine. Consider factors such as the number of spindles or mandrels, the winding speed, and the ability to handle multiple winding operations simultaneously. Ensure that the machine can meet your production volume requirements without sacrificing quality or efficiency.<\/p>\n\n\n\n

For example, if you are a producer of LPG tanks and you need to produce 300,000 \u2013 1,000.000 units per year, a couple of multi-spindle machines with automation can suffice. However, for CNG and CHG tanks, with longer winding cycles, consider at least several winding machines with supporting units for handling to achieve maximum effectiveness.<\/em><\/p>\n<\/div>

Quality and Precision<\/strong><\/p>\n\n\n\n

Filament winding involves creating complex structures, so it’s essential to choose a machine that can achieve the required level of quality and precision. Look for features like accurate tension control, programmable winding patterns, and reliable mandrel rotation. Consider the machine’s track record, reviews from other users, and any certifications or standards it complies with.<\/p>\n\n\n\n

For example, the TCON system \u2013 top-level automation and manufacturing historian developed by Mikrosam<\/strong> \u2013 collects details of process parameters at each step of production in a data warehouse even collecting data from 3rd party auxiliary equipment (e.g. blow molding, testing equipment, etc.). The software integrates the data into the factory ERP to ensure traceability and quality improvement while giving customers unlimited reporting capabilities. The utilization of manufacturing historians such as Mikrosam\u2019s TCON as part of their SCADA<\/strong> system in the filament winding process for manufacturing high-pressure vessels to store hydrogen is indispensable. These systems enable quality control, process optimization, traceability, and predictive maintenance, contributing to the production of safe, efficient, and reliable high-pressure vessels.<\/em><\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n

Support and Maintenance<\/strong><\/h2>\n\n\n\n

Assess the availability of technical support and maintenance services from the machine manufacturer. Filament winding machines can be complex, so having reliable support and maintenance resources can be crucial. Ensure that the manufacturer offers training, documentation, spare parts availability, and responsive customer service.<\/p>\n\n\n\n

For example, Mikrosam provides installation, training, and service support for its customers 24\/7.<\/em><\/p>\n\n\n\n

Cost and Return on Investment (ROI)<\/strong><\/h4>\n\n\n\n

Evaluate the cost of the machine and compare it to the potential return on investment. Consider not only the initial purchase cost but also factors like operational costs, maintenance expenses, and the expected lifespan of the machine. It’s important to strike a balance between affordability and long-term value.<\/p>\n\n\n\n

Safety and Compliance<\/strong><\/h4>\n\n\n\n

Filament winding machines involve various safety considerations. Ensure that the machine adheres to relevant safety standards and regulations. Look for safety features such as emergency stop buttons, protective enclosures, and proper ventilation systems.<\/p>\n\n\n\n

At Mikrosam, each of the equipment stations and integrated automation and control system is designed and manufactured in conformity with EU safety standards and machine directives. To fulfill the International HSE Safety Standards the automated equipment layout is protected with a safety area with fence panels and safety light barriers.
