Kinds of wax tree must be "kind" in a circular rubber chassis.This is the diameter of the rubber chassis with the inner diameter of the cylinder form a complete set of stainless steel.General rubber chassis is 3 inches in diameter, 3 1/2 inches and 4 inches.Chassis is center has a protuberant circular concave hole, the diameter of the concave hole with wax wax rod diameter of the tree."Kind of wax tree" the first step, is to wax rod head dipped some melting wax liquid, strike inserted into a concave hole in the chassis, the wax rod combined with concave hole is firm.The second step, step by step in wax wax mold welding rod, can starting at the bottom of the candle stick (from bottom to top), can also start from wax rod head (down).If the "trees" technology is skilled, the difference of the two methods to operate;But generally use from wax rod head (from the top down) method is more, because the biggest advantage of this method is to prevent melting wax droplet on the welded on the wax models, can avoid unnecessary rework caused by wax droplet falls.
