To know Water Mold Temperature Controller

Water Mold Temperature Controller is the single most important factor in terms of mold productivity. Mold cooling improvements will influence cycle time and part quality - both of which will directly impact profitability.
 
Who is responsible for Water Mold Temperature Controller and why isn't more emphasis placed on it in design and production? Interestingly enough, for such an important part of the molding cycle (80 percent is cooling time), traditional practice is such that no one takes direct responsibility. The molder assumes that good cooling design is inherent in the tool shop's quotation. Tool shops typically do not prioritize mold cooling, nor are their designers necessarily proficient at heat transfer issues. Their forte is cutting steel and producing a mold as economically as possible. Each assumes that the other party is taking responsibility when, in fact, neither party does. There is a hidden cost associated with this industry-wide disconnect. Poorly cooled parts increase cycle time, scrap and dimensional problems.
 
Additionally, cooling loads for each fabrication process can differ significantly for similarly sized parts. For instance, a blow-molded part can only be cooled - by the mold steel - on the outer surface. The inner surface of the part is a hollow cavity. Because of this, there is minimal to no cooling on the inner surface. For blow molding, all of the part cooling is in the direction of the outer wall of the part. Comparing an injection molded part of identical thickness to a blown part, cooling takes place on both sides of the part. The injection part will cool much quicker, resulting in shorter cycles. Therefore, the techniques used to cool the parts for each process type must be well planned to ensure competitive advantage.
 
Water Mold Temperature Controller also has a history of using "flood tooling." This practice involves the use of cast molds with large open cavities for water flow. However, these systems do not concentrate cooling water at the critical part locations such as thicker wall sections or tail flash. This technique fails to provide turbulent flow of water for maximum heat transfer. A drilled passageway system in a cut steel tool will allow for optimized flow rates through passageways and selective placement of passageways where cooling is most required. A drilled passageway system is recommended for any system requiring high-performance cooling and definite temperature control.
