一二二、一一二厂在三○一所及沈阳航院的参加协助下,经过二年来的努力已完成了B阶段环氧泡沫塑料拉型模的研制任务,已用于五种机型的拉型模、高温切割模34套,经部鉴定达到使用技术要求,一二二厂已列为厂标,全面推广使用取代环氧胶砂模。部科技局于九月十一日召开了鉴定会。与会代表一致认为:B阶段环氧泡沫拉型模是实现了以塑代木的变革,达到了轻化的目的,满足了使用技术要求,为国内首创,接近国际水平。经济效益良好:1.体轻:与环氧胶砂比减
With the assistance of 3111 and Shenyang Airways Academy, 112 and 112 plants, after two years of hard work, the task of developing B-stage epoxy foam pull molds has been completed and has been used in five types of aircraft Of the pull-type die, 34 sets of high-temperature cutting die, identified by the Ministry of the use of technical requirements, one or two plants have been listed as a factory standard, the full promotion of the use of epoxy glue to replace the mold. Technology Bureau held an appraisal meeting on September 11. Participants agreed that: B-stage epoxy foam pull mold is to achieve a change of plastic-wood, to achieve the purpose of light, to meet the technical requirements for use, for the domestic initiative, close to international standards. Good economic benefits: 1. Body light: Compared with the epoxy mortar minus
