树脂自硬砂造型(芯)是我厂新开发的生产技术,用以取代CO2硬化水玻璃砂的旧工艺。车间的产品对象主要是一些批量不大、种类繁多、结构复杂且多为组合芯造型的高精度铸铁件,如为我厂生产的各种大吨位叉车及装载机类工程机械配套的箱体、变矩器和轮壳等球铁件和灰铁件;同时也承担了我厂及外协单位在新产品 Resin self-hardening sand molding (core) is a newly developed production technology of our factory to replace the old process of CO2 hardening sodium silicate sand. The main products of the workshop are some high-precision cast iron pieces with small batch sizes, large variety, complex structures and mostly combined core shapes, such as the boxes for various large-tonnage forklifts and loader-type construction machinery produced by our factory, Torque converter and wheel shell and other ductile iron pieces and gray iron pieces; also assumed my factory and the Association of units in the new product
