Compared with the projection area of the molded part, if the clamping force is small, there will be a gap between the movable and fixed molds due to the injection pressure, and burrs will inevitably appear. Especially when the side gate is located on the hole near the center of the part, because these molding gates require a large injection pressure, burrs are extremely likely to occur.
Reducing the injection pressure or increasing the clamping force can eliminate this defect. Sometimes it is very effective to switch to low-pressure molding using flowable plastic, depending on the specific situation.
1.4 Problems with mold damage
Parting line inconsistencies and any obstructions to proper clamping can be corrected by cleaning the mold surface and guides. Damage to the mold tool, clamp misalignment, and machine level should also be checked. Pressure sensitive paper can be used to check and correct these problems.
1.5 The Problem of Form Design
Pressure or flash issues on the part surface can be caused by poor design and excess space in the mold, especially when working with complex geometries and many parts. To solve this nepal number data problem, consider retooling and redesigning the mold.
1.6 The plastic flow is too good
The simple reason is that the plastic is too fluid, which theoretically does not cause burrs. However, when the plastic is too fluid, even small gaps can be penetrated by plastic, so burrs are very easy to occur. To eliminate this burr, you can lower the melting temperature or injection pressure, and you can also lower the mold temperature or injection speed.
1.7 Problems with too low viscosity
Flashing or burrs can occur if the pressure viscosity is too low. In this case, the resin becomes too thin. Some reasons why the resin becomes too thin include.
