The high-temperature capability of Bakelite injection molding machines
is a key feature that sets them apart from machines used for molding thermoplastic materials. Bakelite, also known as phenolic resin, is a thermosetting plastic that requires elevated temperatures to be processed effectively.
Heating System: Bakelite injection molding machines are equipped with robust and efficient heating systems. These systems typically include electric heaters that are capable of reaching and maintaining the high temperatures needed to liquefy the Bakelite resin. The resin needs to be heated to its specific curing or flow temperature, which can often exceed 150°C (302°F) or even reach temperatures above 200°C (392°F) in some cases.
Temperature Control: Precise temperature control is essential when working with Bakelite. The machines feature advanced temperature control systems to ensure that the material reaches and maintains the required processing temperature. This control helps to prevent overheating or underheating of the material, which could lead to molding defects.
Resin Compatibility: Bakelite injection molding machines
are designed to work with phenolic resins and other thermosetting plastics. The materials used in the machine's construction are chosen for their resistance to high temperatures and chemical compatibility with Bakelite.
Mold Compatibility: The molds used with Bakelite injection molding machines are also designed to withstand high temperatures. They are typically made from materials such as hardened steel or other heat-resistant alloys to ensure they do not deform or deteriorate under the elevated molding conditions.
Curing and Cooling: After the Bakelite material is injected into the mold, it must be allowed to cure. Once the part has taken its desired shape, the cooling process begins. Bakelite injection molding machines are equipped to manage this transition from high temperature to cooling efficiently.
Quality Control: The ability to work at high temperatures and maintain precision control over the process allows for the production of high-quality, dimensionally stable parts with minimal defects.JM SERIES BAKELITE INJECTION MOLDING MACHINE ( 178T-408T )
