The phenomenon of jet flow in mold production products in injection molds and the treatment plan for defect jet flow.
The defects such as jet flow that occur during the processing of injection mold products by plastic mold manufacturers are defects that occur on the surface of plastic products, usually near the foot and compression area. This type of injection mold product will be discarded and cannot be used. Due to defects appearing on the surface and appearance of plastic products, even if delivered to customers, it will not be accepted and will definitely be returned. However, if such phenomena occur on internal components and there is no outer layer, it is still possible to communicate with the user to solve them. Generally, defects caused by the spray of such plastic products are acceptable.
Plastic mold manufacturers generally start to address issues such as manual intervention, machine equipment operation, and raw material flowability when dealing with defective plastic product jets. They also need to consider whether the arrangement of injection mold joints is appropriate and the injection speed adjustment in the injection molding process to solve the defects caused by jet phenomena.
Introduction to the causes and solutions of plastic mold injection products such as breakage, bouncing, fracture, cracking, and easy breakage.
Plastic mold manufacturers often perform injection molding operations on plastic products, and their technical personnel may also encounter the phenomenon of plastic product cracking and fracture during injection molding, resulting in waste of time and materials. The main reason for the appearance or structural defects of plastic products caused by breakage during injection molding processing occurs at the corners and relatively thin parts of brittle material products. If there is a product fracture or general breakage phenomenon in injection molding processing, it is necessary to first determine whether the damage is minor or severe, whether it is on the appearance or internal parts. In general, if the situation is not particularly serious, considering the production loss of plastic mold manufacturers, communication with users can be used as appropriate.
Phenomenon and defect spray treatment plan of mold production products in injection molds
The reasons for the breakage of injection molded products in plastic molds are generally due to poor fluidity of the molten material, long flow paths of the plastic, high material brittleness, or poor exhaust design of the injection molding mold, which prevents the product from being fully filled and reduces its strength; The mold has sharp corners, causing stress concentration at the corner position, resulting in hidden cracks or fractures; Uneven ejection and cracked product. The reason for considering the injection molding operation is that the injection speed is too fast, and the high-temperature gas generated mixes with the molten material, reducing the performance of the material; The holding pressure is high, which can stick to the mold and cause cracking or breakage due to force during ejection. The corresponding solution for the cracking and fracture of injection molded products with plastic molds is the same as the cause of the occurrence.
