For an Experienced molding engineer, that is a common problem, but for a fresh molding engineer, maybe It is worth mentioning, at first, in almost every plastic part, there are different thickness, thick sections cool slower than thin sections, […]
maybe there are some plastic products or products with plastic parts at hand, when looking carefully, you can find some of them have textures or lettering on their inner or external surface. […]
When we decide to make textures and lettering on the plastic parts, depth and draft should be considered, draft for texturing is somewhat dependant on the mold design and the specific mold texture. […]
Today I check some mold designs from some Young mold designers, I find a common and Easily neglected problem—they often forget to add drafts in some areas, maybe they don’t realize it’s importance, […]
In the specialized world of mold and insert manufacturing, there are several benefits to employing five-axis machining. For example, five-axis machining adds two more axes of rotation that allows the cutter head to move into positions not accessible with a standard three-axis CNC machine. […]
Moldmaking can be a difficult business to accurately forecast. Work comes in when the OEM/brand owner is ready, and the ability to impact the project launch is out of the hands of the tool shop. […]
Mold validation stages Does the mold work? Activities during this phase relate to the validation of the injection mold’s mechanics. The mold is mounted into the press and dry-cycled (no resin is injected) to ensure it opens and closes normally at operational temperature. […]
Today we discuss how to evaluate the stress concentration factor in a plastic part, actually in last blog, you can find a small illustration, please look at it carefully. there is a Mathematical relationship between radius and thickness for the stress concentration factor. it means when R/T values lesss than 0.5, the stress concentration factor [...]
There are many many sharp corners in every plastic product, what does a sharp corner mean? Sharp corners greatly increase the stress concentration during injection molding.it could lead to failure of plastic parts, especially for the high amount of stress concentration. So generally, as a mold or plastic produce designer, when he or she meet [...]
Boss design is a common design in a plastic part, it is used for mating part or for attaching fasteners such as screws or accepting threaded inserts. […]
