Product catalog summary

Introduction
PLASTIFORM® injection molded magnets are engineered for high magnetic strength and superior physical properties. They are available in bonded ferrite, neodymium-iron-boron, and samarium cobalt, with materials oriented during manufacturing for optimal performance.

Specifications
The magnets offer high energy in bonded forms, manufactured with maximum concentration for robust physical strength and magnetic orientability. The injection molding process ensures precise dimensional and magnetic tolerances, facilitating efficient designs with minimal magnetic flux loss. Standard tolerances are +/-0.003 in/in, with closer tolerances available upon negotiation.

Materials and Binder System
Thermoplastic binders such as nylon 6, nylon 12, and PPS are used, chosen based on temperature capability, strength, and compatibility with the magnet alloy powder.

Assembly and Manufacturing Advantages
The injection molding process supports insert molding, reducing secondary processing costs. Magnets can be produced in simple to complex shapes, with sizes ranging from less than a gram to over 125 grams, typically requiring minimal additional processing.

Applications
These magnets are suitable for various applications, including magnetic stators for DC motors, multi-pole magnetic rotors for brushless DC and stepper motors, magnetic actuators, and sensors for automotive and industrial uses.

Quality Assurance
PLASTIFORM® magnets are produced using statistical process control methods and a computerized quality control system. The Bonded Magnet and Magnet Assemblies Group (BMG) has received numerous awards for service, quality, and on-time delivery.

Prototyping and Tooling
Prototype samples can be provided, with larger quantities available once design parameters are finalized. Sample magnets can be supplied in unmagnetized or magnetized states, with special magnetization patterns available.

Technical Support
Arnold Engineering Services offers assistance with application inquiries, magnetization requirements, magnetic optimization, and prototype testing and evaluation.

Magnetic and Physical Properties
The document details magnetic properties at 23°C, including residual induction, coercive force, intrinsic coercive force, and maximum energy product. Physical properties include tensile strength, elongation at break, hardness, density, and maximum operating temperature.

Overview
This document provides technical specifications for various Plastiform® magnet materials produced by Arnold Magnetics (Shenzhen) Ltd. These materials are polymer bonded and designed for injection molding, offering close dimensional and magnetic tolerances and intricate shapes.
