Motor Neodymium magnet is an alloy magnet made from ND, Fe, B and other trace metal elements. It is a rare earth magnet known so far for the strongest magnetism as well as high performance (8MGOe-55MGOe) and good coercive force. Proven production process, strict quality assurance, complete technical service and remarkable cost performance.
Machining and tolerances
Neodymium is easily ground, although coolants must be used in the process to avoid spontaneous combustion of powder. Grinding should be completed before coating or plating is applied to protect the magnets from corrosion. Standard tolerances for neodymium magnets are +/-0.05mm for ground dimensions.
Temperature constraints
The temperature coefficient of neodymium has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade. Before choosing a neodymium magnet be sure to consider your application's maximum operating temperature.
Added value services
Our knowledgeable engineering department is always available to assist in determining the best grade and size of neodymium magnet for your application. We also offer coating and plating choices for magnets we custom-machine.

PF MOLD uses decades of experience in manufacturing unscrewing plastic injection molds. The output is molds that are used for the production of internal threaded plastic injection parts. External threaded plastic injection do no need to be produced using unscrewing injection molds.
Detailed threads on the Plastic Parts cannot be easily removed from the mold using traditional knock-off, so unscrewing plastic molds have gained popularity not only for its quality but also as a means for cost savings. Unscrewing plastic injection molds can be more complex in design than most plastic injection molds
The molds are operated at high speed to realize faster cycle times. To prevent damaging the threads on the plastic part during production, unscrewing plastic injection molds are being used by the industry.
Unscrewing is widely used for plastic parts that require high volume of output during production. It also prevents damaging the threads on the plastic parts during production. We make unscrewing plastic injection molds to produce high quality parts such as:
Automobile Industry parts
Bolts and Nuts
Bottle caps and closures
Cosmetics containers
Consumer products packaging
Lids
Medical supplie
Personal care products
