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. […]
the material additive processes lead fastest to moldings and are therefore the most promising. These also include new and further in RP. Examples of such techniques are laser sintering, […]
Safety must be a primary consideration of the mold designer. How can a mold, or any heavy mold part, handled safely? No person should repeatedly lift parts heavier than 20KG or any part which is awkward to handle, regardless of weight, without some mechanical assistance, such as a hoist. […]
Time and cost are becoming more and more important factors in the development of new products. It is therefore extremely important for the injection molding industry to produce prototypes that can go into production as quickly as possible. […]
Today morning, I have a meeting with our mold designers about the mold design solution for a new product, we discuss too much design details, I want to pick out some of them to share with every one: […]
