In injection mold products，good materials are generally our success.If the relevant preparations are not enough，there will be a great loss.For example，if the pressure of the injection molding machine is not enough，the pressure of the mold is not enough，and the material flow is not good.Well，the imbalance of the gate will have a great impact，and the lack of material usually depends on the shape of the mold and the fluidity of the material.
When the material is insufficient due to the setting of the molding conditions，the setting of the molding conditions should be set in the direction of the feed liquid，which can not only increase the mold temperature，cylinder temperature，and increase the injection speed and injection pressure.In the ventilation design department of the exhaust port，it is difficult for air to escape in the mold，except for the insufficient material of the product，which causes product paste and melting marks.In these solutions，the mold temperature can be increased，the feed tube temperature can be increased，the injection pressure can be increased，and the gas escape groove width of the parting surface is 5-10mm.The short-term treatment method can increase the gate and increase the flow.In each module and multiple occasions，the cavity is insufficient，the gate is expanded，the configuration process is changed，and the gas escape pin is combined to improve the mold finish.In the long run，avoid designing products with different thicknesses，connect the gate with thicker products，understand product usage，and use liquid materials as much as possible.
