Differences between Thermoset Coils, Thermoplastic Coils, and Hydraulic Coils
Thermoset coils, thermoplastic coils, and hydraulic coils are three common types of electromagnetic coils. The key differences lie in material types, application scenarios, and performance characteristics. Below is a detailed comparison of their structure, performance, manufacturing processes, and applicable fields. 1. Concepts and Definitions Type Definition Thermoset Coil The coil housing is made of thermoset materials (e.g., epoxy, phenolic resin), which cannot be reshaped once cured. Thermoplastic Coil The coil housing is made of thermoplastic materials (e.g., PA66, PBT), which can be repeatedly heated and reshaped. Hydraulic Coil Specifically designed for hydraulic system solenoid valves, with features like high pressure resistance, oil resistance, and corrosion resistance. 2. Material Differences Coil Type Main Material Characteristics Thermoset Coil Epoxy resin, phenolic resin, DMC, BMC High heat resistance, chemical resistance, and dimensional stability, but low ...
