Flexible nitinol wires pass through a rigid precision stainless steel tube to enable articulation of the tube end. This in turn allows surgery to take place around corners as the straight tube which is inserted into the end of the keyhole instrument turns into a hook at its end.

Should a more sophisticated steerable approach to the working site be required, there are alternative approaches to assembly, including the use of tube laser cutting, or a by welding or induction vacuum brazing a separate, more flexible nitinol tube to the end of the rigid stainless tube.

 Stainless steel electrodes are cut to micron precision, allowing copper-based conducting wires to subsequently be laser welded to the electrode itself. 

 Cutting thin wall tubing using conventional methods can result in deformation, burr formation or dimensional inaccuracies. Precision laser cutting eliminates many of these challenges by using a highly focused beam to produce clean, accurate cuts with minimal mechanical stress. This makes the process particularly suitable for delicate components used in medical devices, scientific instruments, sensors and miniature mechanical assemblies. 

  Paarl Precision specialises in the precision laser cutting of hypodermic tubing for medical, scientific and advanced engineering applications. Laser cutting enables intricate features, precision slots, windows and complex profiles to be produced without deforming the tube, making it ideal for components where dimensional accuracy and edge quality are critical. Our process supports both prototype development and production manufacturing using a range of stainless steel and specialist alloy tubing.

 Laser cutting is widely used in the manufacture of catheter components, where precision and consistency are essential. Our process allows complex patterns and fine features to be cut into thin-walled tubing with minimal heat input, helping to maintain the mechanical properties of the material while achieving the tight tolerances required for minimally invasive medical devices. We work closely with customers to develop cutting solutions that meet demanding design and performance requirements.

 Micro tubing presents unique manufacturing challenges due to its small diameter and thin wall thickness. Our laser cutting capabilities enable intricate features to be produced with exceptional precision while maintaining concentricity and dimensional stability. Whether manufacturing miniature medical components, analytical instrumentation or custom-engineered assemblies, Paarl Precision delivers reliable, repeatable results for even the most demanding micro-scale applications. 

  Precision laser cutting provides an efficient and accurate method for manufacturing shims in a wide range of materials and thicknesses. Components can be produced directly from CAD data with exceptional dimensional accuracy, making laser cutting ideal for custom shim designs, prototypes and production quantities. The clean edge quality achieved by laser cutting often reduces the need for secondary finishing before assembly. 

  Laser cut washers offer excellent dimensional consistency and repeatability across prototype and production batches. From simple flat washers to complex sealing and spacing components, laser cutting enables a wide variety of internal and external profiles to be manufactured quickly and accurately without the need for dedicated tooling. This flexibility allows custom washer designs to be produced efficiently with short lead times. 

Thin-wall stainless steel tubes and hypodermic tubes can be precisely and cleanly cut to length by laser cutting. Whilst abrasive wheel cutting and electrochemical cutting are generally more economic, they are less successful then laser cutting for short tube lengths (below 3mm) and for very precise cutting with low kerf widths. This is where laser cutting becomes the preferred tube cutting method.

 Modern sensors often incorporate miniature metallic components with intricate geometries and tight dimensional requirements. Precision laser cutting enables fine features to be produced accurately while maintaining excellent edge quality and repeatability. Our manufacturing capabilities support sensor applications across scientific research, industrial automation, analytical equipment and aerospace industries. 

  Laser cutting is well suited to the manufacture of precision electronic components, shielding elements, contact parts and miniature metallic assemblies. The process enables fine details and complex profiles to be produced without introducing significant mechanical stress, helping to maintain component integrity while achieving the high levels of accuracy required for modern electronic systems. 

  Laser cutting enables narrow slots and precision openings to be produced with exceptional accuracy, even in thin-walled tubing and miniature components. Slot dimensions, spacing and geometry can be precisely controlled, making the process ideal for medical devices, fluid control systems, sensors and other applications where consistent performance depends on precise feature dimensions.

 Precision laser cutting allows intricate window features to be incorporated into tubes and flat components without compromising dimensional accuracy. These windows may be used for fluid delivery, sensing, inspection or mechanical engagement, and can be manufactured in a wide variety of shapes and sizes to meet specific design requirements. 

 From micro-holes to larger precision openings, laser cutting provides excellent positional accuracy and edge quality across a broad range of materials. Hole patterns can be integrated into complex component designs with minimal additional manufacturing time, allowing efficient production of parts requiring multiple precision features. 

 Many advanced engineering applications require features measured in fractions of a millimetre. Our precision laser cutting technology enables the production of extremely small slots, holes, notches and intricate details while maintaining excellent repeatability and dimensional control. These capabilities are particularly valuable for medical devices, scientific instrumentation and high-performance engineering components. 

 Laser cutting offers exceptional design freedom, enabling highly complex geometries to be manufactured directly from CAD data without the limitations of conventional machining or mechanical cutting. Curved profiles, lattice structures, fine contours and intricate patterns can be produced accurately and consistently, allowing engineers greater flexibility when developing innovative products and precision components.
