FAQ
What medical-grade materials do you commonly work with?
We process a wide range of biocompatible and high-performance materials tailored for medical devices, including:
Stainless Steel: 316L, 304, 316LVM (for ultra-thin walls and high rigid needles)
Nickel-Titanium Alloy (Nitinol): For shape memory and superelastic applications (e.g., flexible slotted tubes)
Cobalt-Chromium (Co-Cr) Alloys and other specialty medical metals.
What specialized needle point grinding and secondary processing services do you offer?
To ensure laboratory-level monitoring accuracy and minimize insertion pain for patients, we offer advanced multi-bevel grinding (including customized CGM sensor lancets, insulin delivery needles, and Huber needles). Our secondary capabilities include precision laser cutting/slotting (for “snake bone” flexible tubes), electrochemical polishing, passivating, and custom lubricating coatings (such as medical-grade silicone).
Do you support High-Mix Low-Volume (HMLV) production for medical startups?
es, absolutely. We recognize that medical device R&D requires high flexibility. Providing Custom Material Solutions via an HMLV (High-Mix Low-Volume) model is one of our core competitive advantages. We closely collaborate with both innovative medical startups during their trial phases and industry giants scaling up for mass production.
How can I request a custom sample, and what is the typical lead time?
You can submit your technical drawings (PDF, STEP, or CAD files) through our contact form or email us at [Insert Email, e.g., sales@lijmedtube.com].
Standard prototype samples: Typically take 7 to 14 business days, depending on the complexity of the geometry and material availability.
Mass production: Lead times will be aligned based on batch size and your rolling forecast.
What are the minimum and maximum dimensions of the micro-tubing you can manufacture?
We specialize in ultra-high precision medical micro-tubing. Our advanced manufacturing technology allows us to achieve an inner diameter (ID) as small as 0.03 mm, with wall thickness tolerances controlled down to ±0.005 mm depending on the material and specification. Please contact our engineering team with your specific gauge requirements for a detailed feasibility review.
What quality management systems and regulations do you comply with?
Quality and safety are our top priorities. Our manufacturing facilities strictly operate under the ISO 13485 quality management system for medical devices. We implement stringent in-process sampling inspections (IPQC) and provide full material traceability for every batch we ship.
Can you provide compliance documentation like CMRT or EMRT?
Yes. As a responsible B2B OEM/ODM manufacturer, we regularly support our global clients with international regulatory filings. We can provide standard compliance documentation, including the Conflict Minerals Reporting Template (CMRT) and the Extended Minerals Reporting Template (EMRT), to ensure your supply chain remains transparent and compliant.
How do you protect our proprietary designs and intellectual property (IP)?
We treat intellectual property protection as the foundation of our partnership. As a dedicated B2B OEM/ODM manufacturer, we never market or sell our clients’ proprietary custom components to third parties. We strictly implement internal data segregation, and we are fully prepared to sign a comprehensive Non-Disclosure Agreement (NDA) before any technical drawings or specifications are shared. Your innovations are completely secure with us.
