Transfer molding is typically used for thermoset materials and is slightly different from traditional compression molding. It is a combination of injection and compression molding process. In this process, the polymer is preheated in a holding chamber called the pot. A plunger / pot is then used to transfer the polymer from the pot into the closed heated mold, then compressed into desired shape . Preheating enables lower pressure requirements for the transfer operations and shorten molding cycle. Transfer molding is very useful in producing intricate composite with various plastics and metal inserts. Common examples are gas valves, electronic circuits, and sparkplugs with wires , Seals , O Rings , Electrical Connectors Inserts , Rubber to Metal , Rubber to Plastic , Gaskets .
The process produces less flash as the material is injected into a closed mold.. Transfer molding has many benefits, which include high cavity count, design flexibility with sharper edges, no deflashing necessary as it produces flash free parts, lower cost due to simpler pot and plunger designs, short production cycle compared to compression molding . Some disadvantages include higher mold maintenance as insert transfer tool requires higher mold maintenance, and the tool design could get complex and expensive to include inserts. The overall operation could be cumbersome as each charge is loaded manually.
Micro Technical Team has Designed and Developed Up – Stroking Transfer Moulding Hydraulic press for making the Products from Thermoset Material . These Machines are in Pillar Type Construction Conforming to the Geometrical Tolerances as per JIS b 6403 : 1973 ‘Test code for performance and accuracy for hydraulic presses’ issued by Japanese Industrial Standard Committee (JIS). In addition, meeting Safety Norms as per CE / OSHA Requirement . with Proper Pillar Guiding Arrangement and Automatic Lubrication System which assure the Accuracy of the Movement of Machine Beds .
Gamut of Up – Stroking Transfer Moulding Press from 20 Ton to 1000 Ton with Platen Size from 400 mm x 400 mm to 1000 x 1000 mm . We have developed semi- Automatic and Fully Automatic Machines with Precise Temperature Control up to 400 Degree Celsius in Platens . In Fully Automatic machine Operator has to feed the Raw Material manually , once the Cycle Start signal is activated by operator the Sequence operation of the machine, which is programmed in PLC, will start working . After finishing Bumping , and curing Time the Die will be opened for the removal of the Final moulded Product . Hydraulic System is with Induction Motor . Servo Hydraulic System can also be given with machine on customer Request .
Ancillary Equipment’s such as Tool Lubrication Devices , Conveyors can also be integrated on Customer Request
For any customization required by customer in the standard series of Machines . please collaborate with our Sales – Technical Team 0091-9717474831 Email : sales@microhydrotechnic.co.in . we will be glad to do Design & Manufacture a Hydraulic Press as Per your Requirements.
