Processing Technology: High Precision CNC Machining Center
We use high precision CNC machining centers imported from developed countries to process the core pin blanks. The whole machining precision can be controlled within 0.01mm, which is far beyond the precision of ordinary machining. Precise machining program control also greatly reduces the product inspection rate. We can design and develop precise machining process for different mold core pins. The machining center can also realize automated production, which can effectively improve the production capacity.
Surface Finish: Mirror Polished Ra 0.4μm
The surface treatment of the mold core pin directly affects the quality of the product. We use German imported polishing equipment to mirror polish the core needle, the roughness can reach Ra 0.4μm, far better than the effect of ordinary mechanical polishing. The clean and smooth needle surface can effectively reduce the medical plastic products of sink mark, weld line, surface burrs, bubble marks and other defects.
Inspection equipment: CMM and projector
We use imported CMM to inspect the key dimensions of the core needles and projector to inspect the surface quality of the needles. Together with the self-developed inspection program, we can fully control the key indexes of the products to ensure that each medical core needle is 100% qualified, without any hidden quality problems.
Packaging protection: anti-rust film and foam protection.
In order to ensure the safety of the products during transportation, each core needle will be covered with anti-rust film and fixed with foam to avoid collision and deformation. We also design special packing box for customized products. We can provide you with safe and reliable protection from the factory to the use of the site.
Application Case.
Pipette core needles.
Medical pipettes require a high degree of precision in terms of the size and finish of the inner diameter of the lumen, otherwise the pipetting of reagents and samples will be affected. We have designed core needles with different diameters for different sizes of pipettes, with an inner diameter accuracy of 0.05mm or less, and a mirror-like surface finish to minimize surface defects in the pipette lumen. This greatly improves the smoothness of the pipetting operation and the accuracy of the pipette volume. Our pipette mandrels have been validated by several testing organizations and are fully compliant with medical testing requirements.
Infusion tubing molded needle: medical grade PVC soft infusion tubing
The injection molding of medical-grade PVC flexible infusion tubes requires the use of ultra-precise core needles to ensure the smooth flow of the tubing lumen and to avoid uneven thickness of the tubing wall. We design and manufacture infusion tube core needles with an outer diameter precision of 0.02mm and an inner diameter precision of 0.05mm, which effectively ensure the smoothness of the injection molded infusion tubes. The surface polishing treatment also ensures that the inner wall of the tube lumen is smooth and clean, which will not cause obstruction of infusion.
Precision EEG connector mold core pin.
Medical connectors for EEG devices require very high dimensional accuracy. The molded pins we designed for them are made of imported SUS304 material, and the diameter of the connector is controlled at Φ2.5mm with only 0.01mm deviation between the inner and outer circle. The precision mold core pin can effectively improve the installation accuracy and sealing of the EEG connector. It has been tested that the number of reliable connections can reach more than 3000 times.
Artificial Joint Bracket Core Needles.
Artificial joint stents require high strength and precision of the inner hole. We have designed a precision molded core pin for the fixation hole of the stent, which is machined from SUS303 material, the diameter is controlled to be within Φ6.2mm and the deviation is not more than 0.02mm, and the surface polishing treatment Ra 0.4 makes the inner wall of the fixation hole smooth and clean, and improves the load-bearing performance of the stent. The mold core needle has been verified as a high quality solution by many plastic surgery hospitals.
