Q. What is Transfer molding?
Transfer molding was developed largely to avoid the disadvantages found which compression molding.
• Transfer molding can make intricate or quite accurate parts than possible with compression molding.
• Transfer molding permits the use of intricate inserts and slender cores not practicable with compression molding method.
• Transfer molding produces components of better quality and at economical rates.
The plastic in the power or pellet form is placed in the transfer chamber. Under heat and pressure of approximately 1000 kg/cm2, it is transferred or injected into the closed mold cavity. The curing time required after transfer is just one- third of the compression molding curing time. Another method known as jet molding brings the transfer method closer or injection molding as used for thermoplastics. The plastic materials is forced by ram or screw through a heated jet where it become soft before entering the closed die. Good flowing materials with a long flow period are desirable.
Special Casting Methods: 1. Die casting : Die casting is a permanent mould casting techniques in which molten metal is forced in the mould cavity under a pressure of 700 to
