The AMF series offers Tokyu’s next generation technology that promises high-quality castings and higher productivity. The new AMF series machines are specially designed for high-speed productivity of mould with minimal manpower. These series machines come with vertical blowing and horizontal parting mechanisms. The variable corner squeeze and combined blow mechanism assure high-quality moulding thus increasing casting productivity.
Salient Features
• As the sand shooting and squeezing are at the top of the machine, all cylinders are outside which is open which makes maintenance easier. • The requirement of sand is not so strict (moisture, sand strength, etc.). • Vertical sand shooting uses the gravity force hence lesser air pressure is sufficient. • Pattern change is easy since there is no bolt fixing. • Pouring gate position is easy to change as it can be done outside of the machine. • Horizontal stripping with spring loading makes minimum shift in the mould. Hence after pouring the parting line has very less fins which do not need any grinding. • Little sand fall during moulding which is easy to clean. • Because of the structure of pins and guide slices, the mismatch is small (precision is good) AMF II, AMF IV - 0.2mm, AMF III - 0.3mm. • Pattern plate can be made from wood. Hence the test is easy to take [lesser development time]. • Depending on the casting shape the thickness of sand can be selected accordingly which can save sand cost. • Down sand blowing, the distance is short which is good for filling. • The combined sand blowing has five choices, which can be selected according to the type of castings. • Pouring cup is removed immediately after squeezing so there is no possibility of falling of loose sand into the mould. • Mould thickness can be varied [from 3 to 5 levels] depending upon the type of castings. • The whole machine is open structure which is convenient for inspection and maintenance.
Benifits
• Patterns are cheap and can be made from wood, resin and the price will be 1/6th compared with vertical moulding machine lines. • Because of the horizontal parting, casting product has a huge range. Therefore, the customer can produce many kinds of castings, even if it is not a huge quantity. • Small investment which is 1/2 compared with Tight Flask moulding machine. • Because of the horizontal parting and pouring method the yield is better. • Consistency in mould quality. • High productivity with low manpower.
