At Guérin France, every metal filter is assembled with precision using proven techniques. From assembly method to final finish, our solutions combine strength, compliance, and sector-specific adaptability.
Custom metal filters : assembly methods (welded, crimped, bonded) and protective finishes
Performance built on assembly and finishing
At Guérin France, the quality of a metal filter goes beyond design and materials. It is the customized assembly and tailored finishing that ensure its performance, durability, and compliance with usage constraints. Welded, crimped, or bonded, metal filters must meet specific demands depending on their application sector : industrial, medical, food processing, or aerospace. In this article, explore our various assembly techniques, their benefits, and the protective and packaging solutions we offer to preserve your product’s integrity right up to delivery.
Assembling metal filters : a technical imperative
Why adapt assembly to each application ?
Metal filter assembly cannot be standardized; it must be tailored to the usage environment, technical constraints, and performance requirements of the product. Whether used in industrial, medical, aerospace, or food sectors, the chosen assembly method directly affects the filter’s reliability, seal integrity, and longevity. Customizing the assembly to each use case ensures a perfect bond between components while meeting applicable standards.
Our three methods : welded, crimped, bonded
At Guérin France, we master three core assembly techniques for your metal filters :
- Welded : TIG, MIG, plasma, resistance, laser, tin soldering, and brazing
- Crimped
- Bonded
Combining our technical expertise with your specifications, we propose the most appropriate assembly method to guarantee the performance and longevity of your custom metal filters.
Spotlight on Guérin France’s assembly techniques
At Guérin France, we provide advanced expertise in metal filter assembly. Our three main techniques : welding, crimping, and bonding, are chosen based on the mechanical, environmental, and regulatory demands of your application. Each technique offers specific advantages that we fully master to ensure the quality and durability of your products.
🔩 Welding : strength and durability
Welding is the most widely used method for filters exposed to high stress. It provides strong, long-lasting, and fully sealed joints. We apply various welding techniques, including TIG, MIG, resistance, tin soldering, laser, brazing, and plasma welding, depending on the metal type and filter specifications. This method is ideal for sectors that require high resistance to pressure, vibration, or extreme temperatures.
🔧 Crimping : material preservation
Crimping ensures mechanical fastening without heat input. This method is particularly suitable where maintaining the material’s physical properties is essential. It prevents thermal alteration, making it ideal for sensitive environments or parts with tight tolerances. Crimping also offers a clean, strong, and repeatable finish.
🧪 Bonding : a solution for sensitive environments
Bonding is used to assemble metal filters when chemical resistance or electrical insulation is needed, without heat exposure. With high-performance technical adhesives, this method is ideal for sectors such as medical, pharmaceutical, and electronics. It preserves material integrity while providing excellent sealing and corrosion resistance.
Finishing and protection : ensuring quality all the way to delivery
At Guérin France, the performance of your metal filters goes beyond manufacturing. To ensure their integrity and reliability up to final use, we apply meticulous attention to finishing processes and logistical protection. Every step is carefully designed to preserve product quality, reduce the risk of damage, and meet the hygiene, safety, or precision standards required in your industry.
Pickling : surface cleanliness before use
Pickling is a key stage in the surface treatment of metal filters. It removes manufacturing residues, oxidation, and impurities from the metal, ensuring a clean, uniform, and ready-to-use finish. This process improves part durability and is especially recommended for applications sensitive to corrosion or particulate buildup, such as in the food, medical, or air treatment industries.
Passivation : chemical protection against corrosion
Passivation is used to treat parts by applying a surface protective layer to resist corrosion. It is a chemical surface treatment designed to improve corrosion resistance, especially for stainless steel components. By removing ferrous contaminants and forming a chromium-rich passive layer, this process protects the metal long-term without altering its mechanical or dimensional properties.
At Guérin France, we recommend passivation for critical applications exposed to aggressive environments (humidity, chemicals, steam, or saline atmospheres), particularly in the medical, food, pharmaceutical, and aerospace sectors.
Passivation extends the lifespan of metal filters, reduces the risk of localized corrosion, and ensures better hygienic compatibility for use in sensitive environments. It is an integral part of our long-term commitment to quality and reliability.
Custom packaging : individual, vacuum-sealed, thermoformed
A proper packaging solution is essential to maintain quality. We offer various tailored packaging options based on your product’s nature and destination:
- Individual packaging : Ideal for fragile or high-value parts, it protects against shock, dust, and humidity.
- Vacuum packaging : Recommended for demanding environments, it ensures optimal preservation without oxidation or contamination.
- Thermoformed trays and pouches : Perfect for efficient storage, easy traceability, and ergonomic handling on your production lines.
These finishing and logistical protection methods extend the lifespan of your products and strengthen the reliability of your supply chain.
Why choose custom assembly ?
Choosing custom assembly for your metal filters means selecting a solution that is fully adapted to your technical, environmental, and regulatory constraints. At Guérin France, we design each filter with your specific requirements in mind to ensure optimal performance, durability, and safety.
Enhanced reliability, compliance, and adaptability
Tailored assembly ensures better cohesion between materials, operating conditions, and industrial constraints. This translates to:
- Improved filter reliability in real-world usage,
- Full compliance with quality and regulatory standards across sectors (food, medical, industrial, etc.),
- Optimal adaptability to volumes, geometries, pressures, or thermal conditions.
This level of customization ensures a product that performs effectively from the first use, reducing the need for adjustments or maintenance.
Reduced risk of degradation
Improper assembly can cause defects such as leaks, joint failures, premature corrosion, or compromised mechanical performance. Thanks to our mastered techniques : welding, crimping, or bonding, and our product engineering expertise, we help you minimize the risks of degradation, whether during use, transport, or storage.
Choosing Guérin France means ensuring your metal filters are built with robust precision and long-term reliability, whatever the application field.
