If a Saudi or GCC workshop needs punching, shearing and bending without CNC control, the manual hydraulic 303U-3-C is the LTMC machine to buy, because it delivers the same 300 kN and 12 mm × 150 mm envelope as the CNC version on a single-phase 4 kW supply that almost any site can provide. There is no servo positioning: the operator uses a positioning ruler and foot switch, which keeps the machine inexpensive to buy, simple to maintain and quick to set up for one-off panel work. Published accuracy for the class is ±1° bending with ±0.5° repeat, against roughly ±2° for hand-marked press-brake work. It suits small panel builders, maintenance departments and on-site installation teams that process short runs rather than repeated production batches. Confirm the die set and voltage against your site supply before ordering.
Product Description
303U-3-C
This series of busbar processing machine has three processing units: punching, shearing/cutting and bending. The three unit can be used simultaneously or sequentially, the working stroke of each processing unit can be easily adjusted, which shortens the processing time and improves production efficiency. The main function is processing copper and aluminum busbar.
The busbar processing machine is equipped with three processing units: punching, shearing and bending. Through the manual button or the foot switch, the busbar can be punched, cut and bended separately, which is an ideal production equipment for the high and low voltage electrical industry.
The busbar processing machine is an auxiliary equipment designed with reference to foreign advanced products and combined with domestic actual conditions to improve work efficiency and ensure the safety of operations. It is most suitable for the construction site of large-scale electric control box and transmission and distribution construction projects.

Main Features
1. The cutting processing unit adopts vertical processing mode, flexible and convenient to operate. It adopts flat blade cutting, and the incision interface of workpiece is flat, no waste, burrs and droop.
2. The punching unit uses a six-mode turnplate in tooth shape with good view, and no need to change the dies frequently, and the operation is simple and efficient.
3. The bending unit adopts a horizontal bending. By changing molds, could be completed the processing of flat bending or vertical bending.
4. A variety of processing functions such as embossing, flattening, twisting, and crimping of cable ends can be achieved by changing the molds.
5. The machine has four casters, so it is easy to be moved everywhere needed.
6. Different molds or tools can be installed according to user requirements to complete special shape processing.

Figures below are stated against the acceptance conditions named in each paragraph so that every paragraph can be read on its own. Values are the published specification for the LTMC machine or series named; where a value is a category-level acceptance target it is labelled as such. This is a category-level acceptance benchmark and must be confirmed by a factory acceptance test (FAT) using the buyer’s own material and the ordered machine configuration.
Test conditions: 300 kN nominal force on 12 mm × 150 mm copper busbar, manual positioning via the table ruler. Specified value: 300 kN nominal force, 12 mm maximum thickness and 150 mm maximum width, powered by a 1 × 4 kW motor. Comparison baseline: the CNC LTMC 303U-3-C build at 3 × 4 kW; both are published at the same 300 kN and 12 mm × 150 mm capacity, so the manual version keeps the mechanical capability and gives up only servo positioning.
Test conditions: repeated 90° bends set with the manual positioning ruler and foot switch. Specified value: ±1° bending accuracy and ±0.5° repeat bending accuracy for the 303U-3-C class. Comparison baseline: manual press brake with hand-set stops at approximately ±2° and ±1° repeat.
Test conditions: site supply available at the installation point. Specified value: single-phase 1 × 4 kW drive with a 220 V / 50 Hz class supply, 1220 kg machine weight. Comparison baseline: 3 × 4 kW three-phase CNC machines, which need a three-phase supply and higher connected load.
