Hatian disaster

Hatian disaster

We were setting up a new injection molding workshop and had our first experience with Haitian, it was a disaster:

the machine panels didn't fit and were damaged all over, and the minimum opening stroke didn't meet specifications (350mm requested, 550mm actual). So, we can't mount any molds unless we make false platens.

Have you also had bad experiences with a manufacturer?

Purge chute / drain box

I would like to know if anyone here have any other pictures of what they use to drain raw material from hoppers?

A weird Phenomenon about matte PP plastic ?

We compounded a matte PP with SEBS, but here is a weird phenomenon:When we inject matte PP in small template mould, our matte finish isn't as good as our competitors', but when applied to the client's large, standard product molds, the resulting matte finish is even more beautiful, like a flocked effect—very soft and evenly glossy. How can this be? The injection temperature of the client's large product is actually higher than the injection temperature of our sample mold, who can explain it?
