TOPPLANT-ENG specializes in design and fabrication of rolling mills and associated peripheral equipment.
In particular, we have achievements and experience of more than 40 years in the field of medium to small precision rolling mills.
We have been producing a numerous number of rolling mills for electronic and automotive parts.
Our present major products include advanced machinery for thin plate rolling and wire rolling of Li, Ti and its alloy and Mg alloy.
■ We offer sheet rolling mills for workpieces of mainly 350 mm or less in width and 3.0 mm or less in thickness according to product dimensions, required accuracy and materials.
We are pleased to propose various types such as reversing, non-reversing and 2/4/6-high mills and 2/4-high setup change type mills according to your requirements and product dimensions.
■ Mills to produce flat wires and irregular-shaped wires from round wires (and square wires). Our experience includes large mills for workpieces up to 40 dia.(cold SUS304) and 75 dia. (hot SKD-11). In addition to 2-high mills for flat wires, Turks heads and flat wire 4-direction roll units are available.
■ These roller dies are recommended for finishing polygonal, rough-round and round wires. Compared with conventional roller dies, these roller dies shorten roll exchanging time and dimension adjusting time and improve product finish accuracy (+0/-0.01).
■ These mills are capable of cold and hot rolling of difficult-to-draw wires such as Ti and its alloy and special high-carbon steels. The rolls are of 2-direction V and H and 3-direction type, which are chosen according to materials, etc. of workpieces. Other types include the “common drive type” that drives all roll stands by one motor and the “multi-drive type” that drives one stand by one motor.
■ Mills for producing products measuring 10 mm or less in thickness. Unlike the sendzimir or lone type, the roll housing structure employed is a vertically split type supported by four posts. This structure allows right-side and left-side independent or simultaneous adjustment of the roll gap with a press-down motor. A powder clutch is employed for winding tension, which is capable of consistent tension control in a wide range.
■ A press roll mill for high density forming of nonmetal and powder metal products. Our experience includes both cold and hot (200 degrees[C]) machines and the product dimensions ranging from 0.1 to 3.5 mm in thickness and maximum 350 mm in width, but the maximum width can be increased up to 550 mm. The pressing system available is either hydraulic or servo motor drive (using the screw) or their combination.
