The invention discloses an insulating and exothermic riser for metal-mould low pressure casting and the manufacturing method and application thereof. The insulating and exothermic riser comprises a riser bush and a breaker core, wherein a heat insulating material and/or an exothermic agent is arranged in the riser bush, the breaker core is coaxially arranged at the lower end of the riser bush, and a feeding cavity is formed between the breaker core and the lower end of the riser bush. The insulating and exothermic riser is characterized in that an annular precoated sand sleeve is formed on the periphery of the bonding surface of the riser bush and the breaker core through sand blowing. According to the insulating and exothermic riser, the annular precoated sand sleeve is additionally arranged on the periphery of the bonding surface of the riser bush and the breaker core through sand blowing of a hot box. When the insulating and exothermic riser is applied to the metal-mould low pressure field, the problem of looseness of a local thermal center can be solved simply by embedding the insulating and exothermic riser in a local loose piece, the cost and time for developing a die are saved greatly, efficiency is improved, feeding efficiency is high, and aluminum materials are saved.
