LASER CUTTING

?  Accurate cutting of various complex geometric contours of different thickness, cutting accuracy of micron level;

?  The cutting edge is smooth and no residue, which is helpful for the post-processing.

Example：

?  Stents: cardiovascular metal and polymer stents, occluders, heart valve stents, etc.

?  Catheters: various delivery sheaths, targeted perfusion catheters, cannulas, etc.

?  Developing label ring (Pt ring), orthopaedic implants, snake bone canals, needles, endoscopes and other products processing;

?  Other non-medical products, etc.

LASER SPOT WELDING

?  Precision control welding, processing tolerance in micron level;

?  The weld seam is small (micron level) and no filler is needed;

?  The heat-affected zone is small, which has little effect on the properties of materials;

?  The solder joint has good morphology and no defects such as porosity;

?  It has high welding strength and can be processed with different materials and thicknesses.

Welding cases: nickel-titanium, cobalt-chromium alloy, stainless steel, precious metal (development ring), etc.

 SURFACE TREATMENT

?  Pickling

The oxide layer, stain and molten metal produced during laser cutting stage can be removed. The rust and other impurities can also be removed by immersing the object in pickling solution (acid bath). The oxidation layer on stainless steel, cobalt-chromium alloy and nickel-titanium alloy is removed by acid pickling.

?  Ultrasonic cleaning

Ultrasound cleaning at suitable temperature with clear water, ethanol or other cleaning liquid to remove residues.

?  Electrochemical polishing

It is used for polishing surface treatment of various metals, including nickel-titanium alloy, stainless steel, etc. After treatment, the surface of the product is smooth, micro-uniform, bright and reflective, with excellent corrosion resistance.

NITINOL HEAT TREATMENT STEREOTYPIA

The shape of memory alloys, especially the deformation and mechanical properties of nickel-titanium alloys, can be set by thermal setting. The processed nickel-titanium alloy parts are installed on the special fixture or mandrel, and then put into the heat treatment furnace for heat treatment and shaping.

LASER WELDING OF CATHETERS

?  It has strong anti-interference ability, high stability, fast speed, high efficiency and high welding precision;

?  Shape: The surface of the balloon is smooth after welding with the pipe, which will not cause damage to the balloon;

?  The welded pipe wall of balloon and catheter is regular and uniform, and the welded length is stable;

?  Welding strength: After the balloon is welded with the inner and outer catheters, the welding between the balloon and the inner and outer catheters is firm.

HOT AIR WELDING

?  Functions: Tube welding, tube diameter change, pipe butting, pipe lapping, single and multi-cavity welding;

?  Applicable materials: nylon, polyvinyl chloride, polyurethane, PET, etc.

（ Note: Production of 10000 Class Clean Workshop）

LASER MARKING

?  Advantages: No pollution to the product, beautiful effect, clear and firm marking, stable marking performance;

?  Trial scope: Ultraviolet laser focusing spot is very small, processing almost no thermal impact, suitable for ultra-fine marking of special materials, such as: ultra-fine processing of medical devices, drugs, packaging bottle surface of macromolecule materials, metal surface marking, plastic keys, electronic components, etc.
