Nowadays, the use of injection molded parts is appropriate and extensive, and more and more companies produce injection molded parts. However, many companies still present a variety of products due to unqualified technologies. In the meantime, streak defects are very common among them. So, the Jinhua injection molding process showed streak defects, how should we deal with it? Let's talk about Jinhua blow molding processing, Jinhua injection molding processing and Jinhua plastic toy manufacturers.

The mold is accurately planned, the shunt holes are reasonably arranged, the length of the work zone and the transition of the length change are reasonably determined, the drip shape of the mold bridge, and the reasonable welding angle, so that the welding point falls on the plane of the welding chamber, ensuring the core head of the mold Under the condition of rigidity and strength, to deepen the depth of the welding chamber or expand the cross-sectional area of ​​the welding chamber, it is necessary to choose "sink bridge", which is the basic method to avoid the streak defect of injection molded parts.

Jinhua injection molding should be processed strictly in accordance with the drawings, especially pay attention to the appearance of the advancing shunt hole and the dripping shape of the mold bridge to improve the state of solid metal activity and reduce frictional heat; when the injection molding process with streak defects occurs, the mold should be repaired. The mold worker should go to the site to understand the mold discharge status and determine an accurate mold repair plan; the mold repairer personally investigates the situation of the profile at the moment of discharge than investigating the profile discharge head to determine the role of the mold repair plan is much better; The molds processed by Jinhua injection molding must be nitrided in time according to the rules to ensure the reasonable activity of the solid metal.
