2. Improper setting of toilet molding process parameters. The toilet molding injection pressure is low, the colloid can not overcome the filling resistance; the speed is low, the toilet molding melting time of the glue is long when filling, the fluidity is reduced, resulting in a large filling resistance; the holding time is short, the filling is stopped before the product is filled, etc. Causes the product to be less than glue.
3. Filling channel is blocked. it is necessary to check whether the nozzle, main channel, shunt channel, gate, etc. are unblocked, and if it is blocked, it needs to be cleaned up.
4. The toilet molding mold casting system is defective.
The defects of the mold casting system are divided into the following aspects:
a) the flow path is too small, too thin or too long, increasing fluid resistance;
b) The runners and gates are rough and flawed, or have sharp angles, and the surface roughness is poor, which affects the flow;
