The process of designing mold cavity and core
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. […]
Guidelines for setting the correct mold temperature
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, […]
More details about cooling devices
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, […]
Introduction to the cooling device of mold
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. […]
Guidelines for optimal mold temperature control
In general, the cooling system will be roughly drilled or milled. Rough inner surfaces enhance turbulent flow of coolant, thus providing better heat exchange. […]
The fourth Solution to Solve Mold Cracking, Erosion
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. […]
The third Solution to Solve Mold Cracking, Erosion
Repair by welding–Permanent molds made of steel exhibit longer life because deteriorated areas may be repaired by conventional welding. […]
The second Solution to Solve Mold Cracking, Erosion
Replaceable in serts–One possible solution may be the use of replaceable inserts that can be put in the sprue well area. […]
The first Solution to Solve Mold Cracking, Erosion
Grind the mold area and create a new sprue well by enlarging the old one- This practice is only a temporary cure yielding mixed results. Though the mold is repaired, […]
What are Water Cooling Concerns?
All water-cooling systems require proper maintenance to ensure the passages do not become clogged with scale from minerals in the water. To combat this issue, […]
