an injection mold is expensive
Injection molds are made up of special, high quality materials that have a good machinability property. Some standard mold components such as springs, bolts, […]

This will describe the structure of 2-plate, 3-plate, and runnerless molds.The basic structure of injection mold is determined by the geometry of the product, […]
This checklist can be used as a general reference guide for injection mold design engineers. […]
The old fashioned way but still being used by some mold manufacturers. Designing a mold cavity and core in 2D. Some mold designers may use different procedure. […]
molds are becoming more and more complex, and as a result it is getting ever more difficult to create the proper conditions for effective mould temperature control. Except in the case of simple parts, […]
Cooling of large cores For large core diameters (40 mm and larger), a positive transport of coolant must be ensured. This can be done with inserts in which the coolant reaches the tip of the core through a central bore and is led through a spiral to its circumference, […]
For areas in the mold where it is not possible to use normal drilled cooling channels, alternative methods must be employed to ensure these areas are uniformly cooled with the rest of the part. […]
In general, the cooling system will be roughly drilled or milled. Rough inner surfaces enhance turbulent flow of coolant, thus providing better heat exchange. […]
Cast to the net shape mold blanks–Another effective measure used to extend mold life is the use of cast to net shape tools with their as-cast gating system and cast to net shape mold cavity. […]
Repair by welding–Permanent molds made of steel exhibit longer life because deteriorated areas may be repaired by conventional welding. […]
