Office and Stationery: Mounting documents, notes, or photos on whiteboards, refrigerators, or metal surfaces; organizing cables or small tools.
Home Use: Hanging lightweight curtains, decorations, or kitchen utensils; securing metal items in workshops or garages.
Industrial and Manufacturing: Temporary fixturing of metal parts during assembly, holding templates or gauges on machinery; lightweight magnetic clamping.
Crafts and Hobbies: Model building, DIY projects, magnetic jewelry clasps, or educational experiments demonstrating magnetism.
Retail and Display: Attaching price tags, posters, or promotional materials to metal shelves or display racks.
Strong Holding Force in a Compact Size
Pushpin Magnet uses NdFeB magnetic material to deliver strong holding force (0.5–5 kg) in a small structure. Ideal for applications with limited installation space.
Easy to Install, Remove, and Reposition
The pushpin-style cap provides a convenient grip area, allowing quick handling without direct contact with the magnetic cylinder. Improves efficiency in repeated use scenarios.
Flexible Customization Options
Caps can be customized in ABS plastic, nylon, or stainless steel, with flat, rounded, or hook-shaped designs to suit different installation needs.
Durable Surface Protection
Available with Nickel-Copper-Nickel plating (48-96 hours salt spray resistance), zinc plating (economical for indoor use), or epoxy coating (chemical resistance) for enhanced corrosion protection.
Reusable and Temporary Fixing Solution
Offers a convenient alternative to permanent fixing. Quick to attach and remove, ideal for applications requiring frequent repositioning or temporary holding.
OEM/ODM customization options include:
Magnet size customization: magnetic cylinder diameter, length, and overall dimensions according to application requirements
Magnetic performance customization: different NdFeB grades according to required holding force
Cap customization: ABS plastic, nylon, stainless steel materials with different colors and shapes
Structure customization: flat head, rounded head, hook-shaped cap, and other designs
Surface treatment customization: Nickel-Copper-Nickel plating, zinc plating, epoxy coating, gold plating
Packaging customization: individual packaging, bulk packaging, retail packaging, and export packaging solutions
For industrial customers, customized Pushpin Magnet manufacturing helps improve product compatibility, reduce assembly difficulties, and provide stable supply for long-term projects.
Packaging
For small quantity packaging, Pushpin Magnet is usually packed in blister packs or plastic clamshell packaging with individual compartments. Each package may contain 10-50 pieces and can be labeled with product size, grade, and holding force information.
For bulk orders, magnets are packed in sealed plastic bags containing 100-500 pieces and placed inside cardboard boxes with foam padding to prevent damage during shipping. Desiccant packets can be included to control moisture during storage and transportation.
For safety packaging, small-size Pushpin Magnets can be supplied with child-resistant packaging and warning labels regarding choking hazards and magnetic field risks.
Export packaging follows transportation requirements for magnetic products. Magnetic shielding using steel sheets can be provided when required to comply with IATA regulations for air transportation.
Providing Strong Magnetic Performance in Limited Space
Many products require compact magnetic solutions without sacrificing holding ability. Pushpin Magnet uses NdFeB material to provide strong magnetic force while maintaining a small and lightweight structure.
Improving User Convenience During Installation
Traditional magnets can be difficult to handle due to their small size and strong attraction force. The pushpin-style cap improves grip and allows easier installation and removal.
Reducing Assembly Time for Industrial Applications
For temporary fixing and positioning applications, Pushpin Magnet allows fast installation and removal without additional tools, helping improve operational efficiency.
Ensuring Stable Supply for Bulk Orders
B2B buyers require consistent quality and reliable delivery for repeated purchases. Professional Pushpin Magnet suppliers can provide customized production, quality control, and packaging solutions for long-term cooperation.
1. What is a Pushpin Magnet?
Pushpin Magnet is a small cylindrical NdFeB permanent magnet designed with a pushpin-style cap structure. It provides strong magnetic holding force and is commonly used for temporary mounting, organization, and lightweight hanging applications.
2. What is the holding force of a Pushpin Magnet?
The holding force depends on magnet size and grade. According to available specifications, Pushpin Magnet holding force ranges from 0.5-5 kg.
3. Can Pushpin Magnet be customized for OEM projects?
Yes. Manufacturers can customize dimensions, magnetic grades, cap materials, colors, surface coatings, and packaging according to customer requirements.
4. What coating options are available for Pushpin Magnet?
Common coatings include Nickel-Copper-Nickel plating, Zinc plating, Epoxy coating, and Gold plating. Different coatings provide different levels of corrosion protection and surface performance.
5. What information should buyers provide when requesting a quotation?
Buyers should provide product dimensions, required magnetic force, application environment, quantity requirements, cap design preferences, surface treatment requirements, and packaging needs.
6. Are Pushpin Magnets suitable for industrial applications?
Yes. Pushpin Magnet can be used for temporary fixturing of metal parts during assembly, holding templates or gauges on machinery, and lightweight magnetic clamping applications.
7. Can Pushpin Magnet be used in high-temperature environments?
High-temperature performance depends on the selected magnet grade. High-coercivity grades such as N35H-N40H can operate up to 120°C.
8. How should Pushpin Magnets be packaged for export?
Export packaging can include protective compartments, moisture control packaging, warning labels, and magnetic shielding solutions when required for air transportation compliance.
