About injection mold design
ما هو قولبة الحقن؟
Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.
When You Need to Adjust Your Injection Molding
Because tools are typically made out of steel (a very hard material) or aluminum it can be difficult to make changes. If you want to add plastic to the part you can always make the tool cavity larger by cutting away steel or aluminum.
If you are trying to take away plastic you need to decrease the size of the tool cavity by adding aluminum or metal to it. This is extremely difficult and in many cases might mean needing to scrap the tool (or part of the tool) entirely and start over. In other cases you might be able to weld metal into the cavity that is undesired.
What is essential when designing any injection Moulds?
Applying draft and radii to a part is vital to a properly designed injection-moulded part. Draft helps a part release from a mould with less drag on the part’s surface since the material shrinks onto the mould core.
