the first principle for deciding on the parting line is to assure the plastic part’s appearance. Because during molding, the parting plane may easily lead to welding marks or overflow, it is hard to clean the mold, so a better choice of the parting plane is to help to form smooth, rounded corners on the plastic part.
With all injection-molded parts, there are several ways to address parting line challenges. An awareness of the significance of the parting line is a good start. As stated earlier, parting line location is obvious and not a problem on many parts. For more complex parts, you may be able to use tools within some CAD packages to locate and evaluate split lines, or you can just upload a 3D CAD model online and we’ll propose a parting line and suggest appropriate draft based on that orientation. Our software may also point out that the part cannot be made in a straight-pull mold and that design changes, side-actions, and/or pickouts may be required.
keep in mind that the suggested parting line may not be your only option. Neither your CAD program nor our design analysis software knows how you intend to use the part. Look carefully at the suggested parting line and consider whether its location will work both cosmetically and functionally. If not, there may be other options for your existing design, or you may want to change the design to allow a more suitable parting line for your application.
I’ve found that your blog lists a lot of rules about the design of the parting line, and you’re really a good mold engineer.
as a mold designer, i can understand the importance of parting line
all the rules about deciding the position of parting line you mentioned in this blog are very helpful for my mold design
the position of parting line is very important for mold design
Be careful to determine the location of the parting line, since it cannot be changed after the mold is finished.
yes! parting line design is very important
all the rules for designing parting line you mentioned in this blog are very useful for me:-) thanks!
It is very prudent to decide the position of the parting line， your blog on this topic is very helpful
actually every time, we always have a meeting to discuss this parting line design for a new product
