Insights, expert advice, and industry-leading information to fuel your understanding
Our permanent magnets and magnet assemblies are designed to meet the unique needs of your application. Therefore, as a valued customer, you are assured of quality products, timely service and competitive pricing. Here is a self-serve repository of information pertaining to our magnetic products.
P
Part Submission Warrant (PSW)
A procedure by which the supplier of a part or subsystem gives evidence to the customer that he can satisfy the requirements of Delivery date, Quality, Process Capability and Production Rate.
Passivating
Passivation is the process of treating or coating a metal in order to reduce the chemical reactivity of its surface. In stainless steel, passivation means removing the free iron from the surface of the metal using an acid solution to prevent rust.
Permagraph
The Permagraph is the world-wide known standard equipment for the measurement of magnetic characteristics of permanent magnets in research, development, quality control and production. The Permagraph helps to determine your required magnetic specifications. With this, we make a hysteresis curve, which shows the relationship between the induced magnetic flux density (B) and the magnetic field strength (H).
Permanent Magnet Material
Shaped piece of ferromagnetic material, which once having been magnetised, shows definite resistance to external demagnetising forces, i.e., requires a high demagnetising force to remove the residual magnetism.
Permanent Magnetism
Made from a ferromagnetic material, a permanent magnet retains its magnetism even outside a magnetic field.
The internal structure of the materials keeps it magnetised.
Permanent magnets were once made of steel but we now have a variety of better suited alloys for this purpose.
Polishing
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection.
Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
PPAP On Pre-Production Parts
Production Part Approval Process is used in the automotive supply chain for establishing confidence in suppliers and their production processes. Actual measurements are taken from the parts produced and are used to complete the various test sheets of PPAP.
