砂铸模型材料,短常多采用木材。随着工业的发展,木材消耗量很大。近几年来,对于在保证铸件质量的前提下,如何节约木材,引起了各厂的重视。以金属材料、塑料、菱苦土、蜡木制造模型,虽然它们与木模相比有许多优点,但在制造时,如金属模、塑料模、菱苦土模、蜡本模仍耍用木材做母模,在单件或小批量生产上,采用金属模或塑料模是不经济的。因此,目前生产的铸造模型中,木模还是占了很大的比重。
Sand casting mold material, often use more wood. With the development of industry, timber consumption is very large. In recent years, on the premise of ensuring the quality of castings, how to save wood, aroused the attention of the various plants. Although metal molds, plastic molds, watermelon molds and wax molds are still used in manufacturing, although they have many advantages over wood molds, they are made of metal, plastic, To do the master, in a single or small batch production, the use of metal mold or plastic mold is not economical. Therefore, the current model of casting production, wood mold or accounted for a large proportion.
