;“这上面已经有很明显的痕迹了,所以这本来就是废品,我呢,今天新入职,本着为公司付出的精神,恰巧,这个凹坑问题,我还真知道解决的办法,所以卖弄一下。”

陈凡脸上一直保持着笑容,略停顿后,没等对面陈专家开口,就抢先继续说道。

“这种塑料产品凹坑,业界称之为缩痕,解决方式,有三种,分别是注塑机参数调整,以及注塑模具温度调整,最后是对应缩痕处,注塑模具可以追加火山口结构,避免产品产生缩痕。”

“火山口也是专业术语,意思就是字面理解,对应缩坑处,减铁或加铁的方式,做出火山口形状结构。”

“胡说八道!”陈凡刚说到这里,陈专家面红耳赤的怒喝道。

这是他的专业领域,在这里被一个实习工指手画脚的,这是砸招牌啊!

“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 『加入书签,方便阅读』
