Jinzhong is a leading electric heating element manufacturer in China, focusing on the research and development of clean heating technology and the production of core components for smart home appliances. We have more than 30 years of experience in the electric heating industry, with full-chain capabilities from product design, mold development to precision manufacturing. Our products cover home appliances and industrial fields such as coffee machines, electric irons, water dispensers, and solar heating systems.
The heating tube uses high-purity nickel-chromium alloy heating wire and magnesium oxide insulation, which has the characteristics of high temperature resistance, corrosion resistance, excellent insulation, and thermal efficiency exceeding 95%. It supports single-end/dual-end power supply design, with a power range of 1kW-20kW, suitable for various household appliances, commercial ovens, medical equipment, industrial ovens and liquid heating equipment
The heating plate adopts multi-layer ceramic substrate and nickel-chromium alloy electric heating film technology, combined with ceramic packaging technology, with uniform heat conduction, high temperature resistance and high insulation, and high thermal efficiency. The power (0.5kW-15kW), size and surface material (such as stainless steel, ceramic) can be customized, and it is compatible with PID/PLC system. It has anti-overheating and anti-leakage protection functions, and is suitable for various household heating appliances
The heating film is based on PET/ceramic substrate, with uniform heat conduction, fast response and high reliability, high thermal efficiency, and surface temperature up to 200℃-400℃. It supports flexible surface customization (thickness 0.1-0.5mm), power density 10-80W/cm², adapts to PID temperature control and Internet of Things system, built-in overheat protection and short circuit self-test function, suitable for home appliances (electric ovens, heaters, electric water cups), we provide full process technical support from material selection to mass production.
The die-casting heating solution adopts multi-stage heating modules and dynamic thermal field compensation technology, integrates high thermal conductivity ceramic substrates and alloy heating elements, adapts to high temperature conditions of die-casting molds, supports PID closed-loop temperature control and IoT remote monitoring, and can customize power (5kW-50kW) and cavity distribution structure. It is suitable for coffee machines, electric kettles, electric hot pots and other heating appliances.
The electric heater parts adopts a stainless steel shell, high-purity nickel-chromium alloy heating wire and ceramic insulation structure, combined with multi-layer protective coating and intelligent temperature control module. It has high temperature resistance, corrosion resistance and high insulation, supports modular design (power 500W-30kW adjustable), is compatible with PID/PLC system, and has built-in overheating protection, leakage self-detection and anti-dry burning functions. It is suitable for electric kettles, electric hot pots, coffee machines and other heating appliances.
Electrical heating products cover two major areas: industry and life. They use high-purity nickel-chromium alloy heating elements, ceramic insulation structures and intelligent temperature control technology, combining high efficiency, precise temperature control and multiple safety protections. Industrial-grade products are suitable for high temperature (600°C) and high-load conditions, and support customized power (500W-50kW). Household products focus on safety and energy saving, integrate intelligent temperature control and silent design, and cover electric kettles, air purifiers and other scenarios. The power range is 1kW-10kW.

Dual-element electric water heaters rely on a highly coordinated sequential control system where the upper and lower heating units alternate duties to optimize hot water recovery times and energy efficiency.
A water heater element can easily pass a standard terminal-to-terminal continuity test and still be dangerously broken if its internal electrical insulation has cracked, creating a catastrophic ground fault. This
Facing a pile of wet laundry with a dryer that refuses to heat up is incredibly frustrating, especially if you do not own a digital multimeter to perform standard electrical
Electrical continuity is the absolute foundation of a functional water heater element; if the internal resistive path is broken or compromised, electrical current cannot flow, rendering the entire thermal system
