Q1: What stainless steel grades are available for this puncture needle assembly?
A1: We mainly adopt 304 and medical-grade 316L stainless-steel. Material grade can be selected according to your working medium, application environment and cost-control requirements.
Q2: Can we adjust needle length, tip style and fitting structure of this puncture needle?
A2: Yes, all core structures support full customization. You can provide technical drawings or physical samples. Our engineering team will adjust needle shaft length, tip geometry and fitting dimension to fit your application.
Q3: What surface finishing treatments can you provide?
A3: Mechanical polishing, electrolytic polishing and passivation are available. Electrolytic polishing is highly recommended for medical-related usage to achieve smooth and corrosion-resistant surface.
Q4: Can you guarantee tight tolerance for the adjustable locking fitting?
A4: We use high-precision CNC machining for fitting components. Strict tolerance is maintained for thread and mating size. Each finished assembly will perform fitting test before shipment.
Q5: What is sample lead-time and delivery condition for this custom puncture needle assembly?
