Mysore Road, Bangalore, Karnataka

Ours is a quality-driven organization that is engaged in offering only high-quality products. Thus, we use superior grade raw materials for the fabrication of our entire range. Our packaging materials can retain the products' quality and newness even under extreme shipping and handling conditions. Our packaging provides optimum physical protection. Die casting is a process of forcing molten metal, under high pressures into the cavities of steel moulds. Dies range in complexity to produce any non ferrous metal parts from shrink faucets to engine blocks, components to machinery, Hydraulic Tanks, etc., In fact the process lends itself to making any metal part that might be precise, must have very smooth surface that can be bright plated without prior polishing and buffmg.

Details :

• Having very thin sections must be produced much more economically, must be very flexible in design, a single die casting may have all the features of a complex assembly. Aluminum Hydraulic Oil Tanks are made in Die Castings. Aluminum dissipates more heat compared to Steel components.
• Available Sizes are 20Ltrs, 30Ltrs, 40Ltrs, 55Ltrs, and 70Ltrs. Aluminum looks good than Steel.

Screw Jacks allow to transform a rotary movement supplied by a motor or even a manual operation into a linear movement of vertical lifting, in push or pull, or horizontal position. Their use can take place either individually for various configurations composed of multiple jacks, through the coupling with joints and connecting shafts and bevel gear boxes. Jacks allow to create lift systems with perfect synchronization even if the load is not perfectly distributed.

A Electric Linear Actuators is a hardware which creates the movement along a straight line, in contrast with the rotary motion of a conventional electric motor. The linear actuator is used in automation, automotive (such as management carburetor, moving lights), in computer peripherals (disk drives and printers), valves and other areas of application where there is a linear motion.

Electronic driver for 1 or 2 independent actuators or 2 synchronized actuators 12/24V 10-15A

Features :

• Driver power stage with pulse width modulation (PWM)
• Customizable acceleration and deceleration ramps
• Extreme precision and control for movement and brake
• Current and temperature limits

• Compatible with a wide range of products and different applications
• High efficiency and low losses of power stage

It is designed as electronic driver in low voltage for the control of one or two linear actuators with DC motors through MOSFET transistors with pulse width modulation (PWM). In “sync” mode, the driver ensures the balancing of actuators also in case of extremely different loads in terms of weight, shape, or distribution on the surface, allowing a stroke without any difference between the two actuators.

Main Controls

• Open/Close: synchronous movement

• Trim1 + Trim12 (3 sec): homing

Homing : The driver moves both the actuators in the same direction, according to an adjustable profile, amperometric threshold (controlled mechanical stop) or limit switches, depending on the configuration. It detects automatically the connection’s direction of encoders

Trimming : The driver moves each actuator independently, for mechanical adjustments and a first manual alignment. It is required to check that commands correspond to the direction of movementPossibility to configures on/off delays and reverse the logic.

• The start is provided through fully adjustable voltage ramps.
• The stop is provided through electronic limit switches (or eventually mechanical limit switches), or with adjustable current limits.

Values monitorable through “Monitor” and “Statistics” sections :

• Motors current
• Applied voltage
• Temperature

• Operating mode
• General information about the operating status of the driver

Using the PC interface, it is possible to :

• Consult the errors history (the driver stores each error and the time at which it occurred, from the last start)
• Decide if an error stops the operation (only advanced mode for some errors)
• Decide after how many repetitions of the same error the driver has to block (only advanced mode for some errors)
• Decide the error tripping delay (only advanced mode for some errors)

The connection driver/PC is possible through an USB/UART cable converter.
