In the modern injection molding process, a reciprocating screw drives plastic polymer pellets through a hopper into a heated barrel. As the pellets get closer to the heater, they melt and are pushed into the mold cavity, where pressure is applied. After the part forms and cools within the mo...
This molding method for metal casting molds comprises: a process of covering the bottom block with a pulp molding; a process of setting a flask provided with a vacuum means on the pulp molding; a process of filling the flask with heat-resistant particles; a process of providing a sealing ...
Consider the casting process at 645 B.C, the first traces of the Sand Molding was found. Now consider the state-of-the-art Electromagnetic casting process. Truly, the Casting process has traversed a long path and impacted human civilization for nearly five millennia. With technological advances,...
The ruins of the workshop, believed to be used from 770 B.C. to 650 B.C. revealed the bronzeware casting process including molding, casting and polishing during the Western and Eastern Zhou dynasties, said Gao. He also said the unearthed molds gradually changed in ornamentation, upgrading fr...
