Magnetic Bra Closure for Lingerie Manufacturing
A magnetic bra closure helps users align and close a garment with a simple guided motion. The smooth metal housing creates a clean appearance while the internal magnetic structure supports reliable positioning. It can be integrated into front-closure bras, nursing bras, sports bras, post-surgical garments and fashion lingerie.
The correct closure should be selected according to garment construction, fabric layers, opening direction, required holding force and the intended user. We recommend testing production samples on the finished garment before confirming a bulk order.

Materials, Finishes and Strength Options
Material and Surface Finish
Available housing materials include stainless steel and zinc alloy, subject to size and construction. Finish options include gold, silver, rose gold, gunmetal, matte black and custom electroplated colors. Material and plating requirements should be specified together with applicable testing standards.
Forza magnetica
Holding force can be adjusted to balance security and ease of release. A stronger magnet is not always the best choice: the final selection depends on band tension, fabric thickness, seam position and opening direction. Richarms can prepare samples with different magnetic configurations for comparison.

Magnetic Bra Closure Applications
- Front-opening bras designed for easier dressing
- Nursing bras requiring convenient access
- Sports bras requiring a compact, secure fastener
- Adaptive and post-surgical garments
- Fashion lingerie with visible metal hardware
- Underwear side closures and adjustable garment structures
Installation and Product Development
The closure may be sewn into a fabric channel, attached through a compatible loop structure or integrated by another approved method. Installation must prevent the metal housing from rubbing directly against the skin and must distribute load across the surrounding fabric. For mass production, confirm seam allowance, reinforcement, wash requirements and assembly direction during sample development.
