Neodymium Magnets Wholesale for Custom Projects and Magnetic Assemblies

Yes. Custom neodymium magnets are one of our core strengths.
We can manufacture magnets based on your drawing, existing sample, target dimensions, or actual application requirements. Many customers do not start with a perfect technical specification. Sometimes they only have a rough sketch, an old part, or a general performance target, and that is usually enough for us to begin the discussion.

For most custom magnet projects, we normally confirm these key points first:

• Magnet grade / magnetic performance
• Coating
• Dimensions and tolerance
• Magnetization direction or number of poles

We mainly focus on products where we have real advantages, especially micro magnets, large magnets, high-grade neodymium magnets, and irregular-shaped magnets. If your project is still under development, we can also help review whether the design is practical for production.

Yes. If you are not sure which grade is right, we can recommend a suitable option based on your real application.
Many buyers know they need a neodymium magnet, but they are not always sure whether they need N35, N42, N52, or an even higher grade, or whether the project also needs better temperature resistance.

In practice, choosing the right grade is not just about picking the highest number. We usually evaluate:

• Required magnetic force
• Working temperature
• Available installation space
• Safety margin
• Cost target
• Machining difficulty

We can support projects up to N56, but a higher grade is not always the best or most economical choice. In many cases, we help customers choose a more balanced solution that works better in real production.

The safest way is to evaluate the magnet based on your real application conditions, not only by looking at the grade name.
A magnet that looks strong on paper may still perform differently in an actual product because magnetic force is affected by many factors, such as:

• Magnet size and shape
• Working gap
• Material of the mating part
• Installation position
• Air gap and contact area
• Temperature
• Magnetization direction
• Whether the magnet works alone or in an assembly

If you share your application background, target pull force, or structure, we can help you judge whether the selected magnet is likely to be sufficient. For many projects, customers also start with samples or a small trial order before moving into bulk production. That is usually the most practical way to reduce risk.

Yes. Coating selection is an important part of magnet customization, and we can recommend it based on your application environment.
Neodymium magnets are strong, but they also need suitable surface protection. The wrong coating may lead to corrosion, appearance issues, reduced durability, or packaging problems during use.

We usually recommend coating options after understanding:

• Whether the magnet will be used indoors or outdoors
• Whether there is humidity, water, salt, or chemical exposure
• Whether the product has medical or cleaner-environment requirements
• Whether appearance matters
• Whether there is friction, impact, or wear

So instead of choosing coating only by habit, it is better to match it to the actual working condition. A suitable coating improves both product stability and long-term reliability.

Yes. We can support a wide size range, from about Ø0.2 mm up to Ø300 mm depending on the project.
This range covers both very small precision magnets and much larger industrial magnets. That flexibility is important because many buyers do not need only standard sizes.

Typical applications include:

• Micro magnets for compact devices
• Custom magnets for motors or instruments
• Large magnets for industrial assemblies
• Special dimensions for OEM products

If your required size is unusual, it is best to send the exact dimensions or drawing. A clear drawing allows us to evaluate feasibility, tolerance risk, and production method more accurately.

Yes. We can support samples and small trial orders, even before a larger wholesale order is confirmed.
This is very common for new product development, supplier testing, or performance verification. We understand that many customers need to confirm fit and function before committing to volume production.

At the same time, it is important to be transparent:
sample orders are usually charged, and small-quantity orders normally have a higher unit cost than bulk orders.

That is because custom magnet production still involves:

• Material preparation
• Machining
• Magnetization
• Inspection
• Packaging
• Sometimes tooling or setup work

For many customers, starting with a paid sample order is still the most efficient way to reduce project risk before scaling up.

Yes. We can support customized magnetization direction and, for suitable projects, multi-pole magnetization requirements.
For custom neodymium magnets, magnetization direction is one of the most important technical points, but it is also one of the most commonly overlooked.

A magnet may have the correct size and grade, but if the magnetization direction or pole arrangement is wrong, it may not work properly in the product. This is especially important for:

• Motors
• Sensors
• Magnetic assemblies
• Rotating parts
• Fixtures
• Applications with space limitations

When quoting, we usually encourage customers to confirm not only the magnet size, but also the charging direction or required pole layout. This helps avoid costly errors later.

For serious wholesale buyers, consistency matters just as much as the first sample, and we understand that clearly.
A sample that works well is only valuable if the mass production parts remain stable. In actual projects, customers usually care about consistency in:

• Dimensions
• Tolerance control
• Coating quality
• Magnetic performance
• Magnetization stability
• Assembly fit

Our product strategy is to focus only on product lines where we can offer real advantages in quality and service, rather than trying to do everything. That helps us control projects more carefully. For customers with stricter requirements, we can also discuss inspection focus points early in the project so expectations are clear before mass production begins.

Yes. We can support projects with higher technical or cleanliness requirements, depending on the application.
Some magnet applications are much more sensitive than general industrial use. For example:

• Medical-related products
• Precision instruments
• Motors
• Compact devices
• Sensitive assemblies
• Projects requiring cleaner handling or better packaging control

We can support medical-grade requirements and clean packaging needs for suitable projects. If your application has stricter standards, it is best to mention them at the quotation stage so we can judge the right production and packaging approach from the beginning.

Yes. This is one of our strongest areas.
Many suppliers can sell individual magnets, but not every supplier can support a project where the magnet must work together with metal components, structural parts, assembly requirements, and magnetic performance targets.

Our team has stronger experience in:

• Magnetic assembly design
• Metal processing coordination
• Assembly feasibility
• Magnetic simulation support
• Project-based OEM/ODM development

This is one of the reasons we are well suited for customers who need more than a standard magnet. If your project is really about a functional magnetic solution, not just a raw magnet piece, we can usually provide more useful support.

For many custom neodymium magnet projects, our normal lead time is around 25 days.
However, the actual lead time depends on several project-specific factors, including:

Magnet grade
Size and shape complexity
Tolerance difficulty
Coating process
Magnetization requirement
Quantity
Whether assembly work is needed
Whether it is a repeat order or a new development order

Simple repeat orders are often easier to schedule, while new custom parts or magnetic assemblies usually need technical confirmation before the timeline can be finalized. If timing is important, it is always better to align technical details early so production planning is more accurate.

International express shipping is usually around 7 days, while sea freight may take much longer and can be delayed by inspection.
For many magnet shipments, express delivery is the more common choice because it is faster and easier to control.

Still, customers should know the practical difference:

• Express shipping is commonly around 7 days
• Sea freight may face inspection
• If inspected, sea shipments may be delayed by around 1 month

Because magnets are a special product category in international logistics, it is important to plan shipping early, especially for urgent orders. If your delivery schedule is tight, we usually recommend discussing transport timing before the order is finalized.

We are an independent trading company with a factory background, and that gives customers both technical support and sourcing flexibility.
OSENC was established in 2019. We are connected to factory resources, but we are not just the foreign trade department of a factory. This difference matters because it affects how we solve customer needs.

For buyers, the practical advantage is:

• Factory resource support
• Better flexibility in sourcing
• More room to optimize solutions
• Ability to focus on the products where we truly have advantages
• Stronger support for custom and project-based work

Instead of trying to sell every possible product, we focus on product lines where we can really offer quality, service, and useful technical support. That usually leads to a better customer experience.
