Q1:How to control the flow rate of side holes? Can different diameters of side holes be customized?
A: The side - hole flow is jointly determined by the aperture size, number of side - holes, and fluid pressure. We support customizing the side - hole aperture (0.1 - 1.0mm), the number of side - holes (1 - 4), and the side - hole position (adjustable from 5 - 50mm from the tip). You can provide parameters such as target flow (such as 0.1 - 500mL/min) and fluid viscosity (such as water, syrup, oil), and we will match the optimal side - hole design for you through fluid simulation + actual measurement verification.
Q2: Is the needle prone to clogging? How to clean and maintain it?
A: The needle tip is electropolished (Ra≤0.2μm), and there are no burrs at the edge of the side - hole, so the fluid has little resistance when passing through and is not easy to retain impurities; daily maintenance can be carried out by CIP (Clean - in - Place) , or after disassembly, ultrasonic cleaning , and then storing it in a clean environment after drying.
Q3: What is the thinnest customizable needle gauge available? What is the maximum length that can be manufactured?
A: The minimum customizable needle diameter is 0.3mm (strength needs to be evaluated, it is recommended ≥0.3mm for high - frequency operations), and the longest needle body can be customized to 300mm ; the minimum distance from the side - hole to the tip is 5mm (to ensure structural strength), and the maximum distance is 50mm .
Q4: What advantages do your needles have compared with plastic side-hole needles?
A:1. Material Strength: The stainless steel needle has high hardness (HRC≥50), is resistant to bending and wear, while plastic needles are easy to deform and age, and their service life is only 1/10 - 1/5 of that of stainless steel;2.Temperature Resistance: Stainless steel can withstand temperatures ≤200℃, while plastic needles generally ≤80℃, unable to adapt to high - temperature sterilization production lines;3. Hygiene: The stainless steel is integrated without dead corners, while plastic needles have splicing gaps, which are easy to retain microorganisms and do not meet GMP standards;4. Customization: The side - holes, length, etc. of stainless steel needles can be flexibly customized, while plastic needles are limited by molds, with great customization difficulty and long cycle.
