Quality Management
Earning Our Customer’s Trust
The magnet, as the significant part for assemble, before released from the magnet factory, it is essential that it successfully passes an inspection of demanded standards set to meet the customer’s needs. Giving our customers the confidence that every magnet will be delivered on-time and according to specifications.
Dimensional & Apperance Inspection
Considering about the accuracy, efficiency, and cost competitiveness, human inspection alone is unable to keep up with the pace. So we have invested in automatic inspection machines that quickly and accurately measure multiple dimensions, appearance, and reject unqualified parts at a very high production rate.
Measuring Dimensions
From blanks to finished products, we use calipers, micrometers, and other precise measurement tools to measure magnets’ dimensions. In manufacturing, we may discover any variations and take remedial steps if required by comparing the actual size of the magnets to the design specifications. This guarantees that the magnets fulfill the size, shape, and tolerance requirements, for their correct performance and compatibility with other components in an assembly.
Measuring Apperance
Cracks, chips, anomalies in form or surface finish, and inconsistencies in coating or plating are all common faults to check for. Identifying these flaws early in the quality control process ensures that only high-quality magnets are utilized in applications, reducing the chance of failures or malfunctions.
Measurement of Pull Force & Gauss
Measure the Pull Force
Pull force refers to the amount of force required to separate the magnet from a ferromagnetic material, such as iron or steel, when they are in direct contact with each other.
Determining the pull force may better understand the magnet’s performance in real-world applications such as holding or lifting things.
Measure the Magnetic Field
By measuring the magnetic field, we can ensure the neodymium magnets meet the specified grade, strength, and quality standards. This helps us maintain consistency and reliability across different batches of magnets.
Measurement of Platings
Salt Spray Test
The coated or plated magnet is subjected to a controlled saltwater mist. The period of exposure and the appearance of corrosion are then utilized to evaluate the coating or plating’s corrosion resistance.
Plating Thickness Test
We can guarantee that the plating thickness satisfies the specified criteria and offers enough protection and performance for the applications we want to use.
Drop Test
By performing a drop test to assess the adhesion of plating on a magnet, we can ensure that the coating is durable and well-suited for its intended application.
Temperature Resistance and Thermal Stability
Temperature Test
Neodymium magnets can be sensitive to high temperatures, which may cause a loss of magnetic strength or even structural damage.
To test a magnet’s performance under various temperature conditions, place it in a temperature-controlled chamber and subject it to a range of temperatures above and below its maximum operating temperature. Measure the magnetic properties at each temperature level to evaluate the magnet’s performance and stability.
Magnetic Property Tests
B-H Curve
The B-H curve is a graphical representation of the relationship between the magnetic flux density (B) and the magnetic field strength (H) in a magnetic material.
We use it to inspect and characterize the magnetic properties of a magnet and provide valuable information about its performance under various magnetic field conditions.
