Probe socket shell plastic mold opening injection difficulties

What does the probe socket housing plastic mold look like? What are the difficulties of mold injection molding?

Today we will talk about the probe socket shell plastic mold mold injection molding difficulties in the specific difficult.

One of the most common defects in plastic mold opening injection molding is cracking, the main reason is caused by stress deformation, the main types are residual stress, external stress and stress deformation generated by the external environment.

(1) The cracking caused by residual stress is mainly caused by excess filling, release and metal inserts.

(2) The cracking caused by external stress is mainly due to the stress concentration caused by unreasonable design.

(3) The cracking caused by the external environment is mainly due to the water degradation caused by chemicals and moisture absorption, and the excessive use of recycled materials deteriorates the physical properties.

Insufficient filling caused by insufficient resin capacity, insufficient pressure in the cavity, insufficient resin fluidity, and poor exhaust effect is also one of the concerns in the injection molding process, and poor treatment will cause injection defects.

Wrinkles and pockmarks, shrink pits, overflow edges, banquets, burns, bubbles, warping deformation, etc. are the difficulties of probe socket shell plastic mold opening injection molding, which are the difficulties to be solved by injection molding mold factories.
