Resettable Fuse Manufacturing
Resettable fuse is my company's own development of over-current protection components, my company am using the high molecular organic polymer at a high pressure, high temperature, vulcanization reaction conditions, adding conductive particles doped material, Manufactured through a special process. The basic steps include: weighing, mixing, dehydration drying, (dry press made into a round, rectangular, round, honeycomb blank) aging, testing and testing process. encapsulated with flame retardant epoxy or polyester film conforming to UL94V-0 or IEC95-2-2. you can customize your desired product parameters. by reading our different product manufacturing services, learn how we can ensure product quality standards, please contact us for quotation or free samples.
What Is Resettable Fuse?
The resettable fuse is an overcurrent protection element that replaces the normal current fuse and can be automatically reset after disconnection. Resettable fuse is made of a polymeric material filled with carbon black particles, this material has a certain conductivity, thus being able to pass the rated current. if the current through the resettable fuse is too high, its heating power is greater than the cooling power, at this point the temperature from the recovery fuse will begin to rise, while the polymer matrix in the resettable fuse begins to expand, this will separate the carbon black particles, and lead to resistance rise, thus very effectively reducing the current in the circuit.
Resettable Fuse Characteristics
1, Because the polymer PTC resistance is recoverable, and thus can be repeated multiple use
2, Polymer PTC thermistor can be used for computers and their external equipment, mobile phones, battery packs, telematics and network equipment, transformers, industrial control equipment, automotive and other electronic products, there are over-current or over-temperature protection.
3, Polymer PTC thermistor and ceramic PTC thermistor is the difference between the initial resistance, action time and size difference. polymer PTC thermistor size is smaller, lower resistance, while faster response.
4, Storage time is long.
5, PTC thermistor can be used in parallel, advantage is to reduce the resistance and increase the holding current.

Ramming mass is commonly used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries.
Ramming mass is widely used in non-core intermediate frequency furnace and core induction furnace.
As an intermediate frequency furnace ramming material, refractory ramming is applied to melt gray cast iron, nodular cast iron, malleable cast iron, vermicular cast iron, and cast alloy steel; to melt carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, molten aluminum and its alloys; to melt red copper, brass, white brass, bronze and its alloys, etc.
Induction furnaces are used for melting cast iron, mild steel and various alloy steels in foundries and making of steel in mini steel plants using sponge iron
The refined high silicon, low iron quartz sand and quartz powder are selected and the fused quartz sand is added as the refractory material., with no slag, no crack, damp proof, convenience of repair, and the corrosion resistance, thus greatly improving the furnace service life span and the economic benefit..
Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks
Acid ramming material is the premixed ramming mass of the lining material. The acid ramming mass is used to smelt a series of metal materials such as ordinary steel and carbon steel.
The lining practice best suited to a particular furnace depends upon the capacity and design of the furnace, operation practice adopted during making of a heat, and furnace output.
