第003章:塑料工业(2 / 2)

“你一个实习工,态度不放正,不知道认真学习,却在这里大放厥词,你懂什么是注塑工业么?!”

“陈专家,您先别激动,对公司来说,我说的方法,对与不对没有任何损失,反之,若是我的方法真解决了问题,那对公司创造的价值,就不仅仅是金钱方面了,这种毫无成本的投资,没理由不去做啊?”

这一句话,直接堵得陈专家没话说。

陈凡站在公司的利益角度出发,这就是当下的大义,没理由反驳…

“所以呢,且先听我说完。既然有了解决方法,我再讲一下为什么会产生缩痕。”

陈凡控场很成功,所有人都被带进他的节奏当中,聚精会神的听着。

“众所周知,塑料这种材质,热胀冷缩的现象,是最为直观体现的。因塑料是高温注胶,它在最初成型时的大小,跟冷却过后的大小,是有区别的,相信这一点在座诸位都明白这个道理。”

所有人不约而同的点点头。

“所以,塑料产品有主壁厚级副壁厚之说,通俗来讲,就是产品最大面积的平均厚度为主壁厚,而局部交叉面积的厚度为副壁厚,按照塑料材质的热胀冷缩原理,副壁厚的厚度,不能超过主壁厚厚度的百分之五十。”

“很好理解的不是么?想想看,副壁厚厚度超过了主壁厚厚度一半,那样在冷缩过程中,副壁厚在缩小啊,那样会不会向下拽?所以导致产品缩坑出现?”

陈凡说到这里,不明白的人,依旧是一脸懵逼,而懂行的人,却是有一种豁然开朗的感觉。

其中就包括陈专家。

“所以,注塑机参数调整时,要加大保压以及冷却时间,在注塑产品四面压力逐渐增强时,会一定程度限制它的缩小,因为压力的填充,可供缩小的空间没有!”

“至于模具温度控制,那就更好理解了,降低模具温度,加快产品冷却,只要冷却速度过快,缩水现象肯定会有所减缓的。”

陈凡话音落下,人群中最早向陈专家诉苦的技术人员,急忙按照要求,尝试了一下注塑机参数的调整,保压加大,冷却时间增加!

随后开始试验!

至于实习生们,则是一脸震惊的看着陈凡,特别是最了解陈凡的李成刚,他都感觉不认识这个寝室兄弟了。

这侃侃而谈的样子,掌控全场的节奏,不卑不亢的态度,这家伙,被附身了?!

实习生中的两位女士,也是目光异彩涟涟的看着陈凡,她们还未被社会熏陶,因此,此刻的陈凡,真的很吸引人。

而此时最为紧张的,就非陈专家莫属了,看着注塑机正在尝试陈凡的方法,他担心真的解决了问题,那这张脸就没法要了……

“产品出来了!”

不到一分钟,重新调整过参数的注塑产品就成型了,技术员急忙拿出产品,随后认真仔细的检查着。

没过一会儿,他一脸吃惊的看着陈凡,那目光有些复杂。

“这一件产品,没有凹坑了!”
