Features

· Sunlight series exothermic insulating riser sleeve have high calorific value, high strength and toughness. It is made of light heat insulating material, with the exothermic compound has high calorific value and cause no pollution to the alloy, to ensure the riser has a higher feeding capacity. It is of low air evolution, good air permeability, nd specifications and can provide the corresponding flap.

· Sunlight series riser can help produce more casting by the same amount of molten metal; Increase the weight of casting; Reducing energy costs and the consumption of molding sand and binder; avoid the waste product caused by shrinkage cavity; minimize cleaning and polishing costs as while as the melting loss of precious metal alloy.
