Threaded inserts for plastic molding knowledge

Need to pay attention to the situation is the case of particularly deep fine groove, know that the thinner the repair of the wheel, the lower the height can be repaired, so cut the groove when the wheel can be repaired as shown below, the top part of the avoidance , Reduce the difficulty of the last paragraph of the tank processing, as shown:

Finally, talk about sheets (usually around 0.5MM can count sheets) case grooving, this is generally more difficult, mainly by the master of the experience and technology to complete, but still in the design can be optimized master may not have a lot of attention to this area , various types on the sheet material with the insert is not the same, such as the commonly used SKD61, SKD11, SKH-9, DC53, VKING the like, in fact, a steel stuffing of books know, the demand for a variety of mold steel Is different, just on the connector, there are several commonly used above types, because inserts are generally relatively small, so the smaller insert, the general choice of materials with higher hardness, such as SKH-9, hardness To 60-63 ° appearance, but when the connector thin-walled grooving, will produce deformation, even if the elastic deformation, the final will affect the accuracy of processing, so this is also for the thin insert grooving, VKING steel generally used the reason!
