(二)白金铸粉不锈钢铸粉操作步骤

建议混合液浓度： 用高科浓缩粘合剂4.5-6毫升+ 95.5-94毫升水充分搅拌 Suggested density of solution: Mix4.5-6ml GAOKE-Bind concentrate to 95.5-94ml water. Always add concentrate to water. 配制适当浓度的混合液 Prepare solution   称量所需铸粉重量 Weigh investment 量度所需混合液量 （30～40毫升混合液兌100克铸粉） 30-40ml solution to 100g powder
将铸粉加入混合液中 Always add investment to solution 用电动搅拌器混和10～15分钟 Mix 10 to 15 minutes 用抽真空机抽出搅拌砵内 铸粉的空气1分钟 Vacuum for 1 minute.
用塑带纸围住铸模杯顶部并高出顶部2cm Wrap plastic film avound the top of flask and secure with a rubber band, ensuring that there is at least 2cm of plastic film above the top of flask. Please flask over sprue tree. Place flask on to bmm(1/4")stack of highly absorbent paper towels and seal with wax. 将铸粉浆贴壁慢慢倒入铸 模杯，直至高于铸模杯上沿口1～1.5cm Pour the slurry down the side of the flask. Avoid pouring directly onto the sprue tree. Fill 1-1.5cm over the top of the flask.
抽真空2～3分钟（带振动） Vacuum up to 2.5 to 3 minutes. Vibrate vigorously during Vacuum procedure. 将铸模杯轻放置于铺平的吸水粉 上面脱水，静置时间2.5小时左右 Place flask on to level absorbent powder, leave still for about 2.5hrs. 待水全部被吸干后，去掉铸模杯 顶部的塑胶纸圈及底部的脱水纸 Remove collar wrapping after the flask becomes completely dry.
放入常温炉升温至 950～1000℃恒温1小时以上 Bumout Process: 1. Place in cool oven 2. Raise to 950-1000℃ 3. Hold for above 1 hour 用刀刮去铸模杯顶部多余的铸粉 Carefully scrape excess investment from top of flask.     倒模后放置3～5分钟后溃水（爆水） deflasking: leave still 3-5 minutes after casting, then deflask.

注意：

1、因各型号铸粉用途和使用方法稍有区别，如需更详细的使用资料，可致电本公司免费索取资料和试用装产品；

2、铸粉中含有石英，使用时应注意遵守石英粉安全使用规程。
