Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. As a specialized manufacturer established in 2017, we take pride in offering the Optical Transmittance Tested Lab Guidance Tube with Precision Graduated Line. This custom plastic molding solution is engineered for laboratories and quality control environments where accurate light transmission and clear measurement markings are critical. Our product is backed by a TS16969-certified manufacturing process, ensuring consistent quality and reliable performance for demanding applications in sectors such as medical, automotive testing, and scientific research.
The guidance tube serves as a precise holder or channel for optical fibers, sensors, or test samples, featuring integrated graduated lines for easy visual measurement. Each unit undergoes 100% optical transmittance testing to guarantee uniform light passage, making it an ideal component for spectrophotometers, refractometers, and other optical instruments. Our custom plastic molding capabilities allow for complex geometries, tight tolerances, and surface finishes that meet the highest industry standards.
Below we outline the key features, specifications, and benefits that make this product a reliable choice for your laboratory needs.
Key Features & Technical Specifications
- Optical Transmittance Verified: Every tube is tested using calibrated instruments to ensure consistent light transmission above specified thresholds (e.g., ≥90% for clear materials).
- Precision Graduated Lines: Laser-engraved or molded scale markings with accuracy within ±0.1 mm, available in metric or imperial units.
- Custom Plastic Molding: We support materials like PC, PMMA, PS, or ABS, with optional UV resistance, anti-static, or high-temperature grades.
- IATF16949 Compliant Manufacturing: Our production lines follow automotive-grade quality standards (IATF16949 framework), ensuring repeatability and defect control. (Note: We operate under TS16969 certification, which aligns with the IATF16949 system.)
- Lab Guidance Function: Designed to guide fibers, wires, or fluids while providing a clear visual path for inspection.
- Surface Finish Options: Smooth (Ra ≤ 0.8 μm) or matte texture available, depending on application requirements.

Frequently Asked Questions (FAQ)
- Q: What materials can you use for the tube? A: We commonly use PC (polycarbonate), PMMA (acrylic), ABS, and PS. For special requirements like UV resistance or high clarity, we can suggest alternative materials.
- Q: What is the accuracy of the graduated lines? A: Standard accuracy is ±0.1 mm. For higher precision (e.g., ±0.05 mm), laser engraving is available as an option.
- Q: Do you provide optical transmittance test reports? A: Yes, we can include a test report for each batch or sample. Standard testing is done at 550 nm, but other wavelengths can be specified.
- Q: Is the product suitable for medical or food contact applications? A: Depending on the material, we can offer FDA-compliant or USP Class VI grades upon request. Please confirm your specific requirements.
- Q: What is the minimum order quantity (MOQ)? A: MOQ for custom plastic molding is typically 500 pieces, but smaller quantities are possible for prototypes or samples. Contact us for details.
- Q: How do you ensure the tube dimensions stay consistent over large production runs? A: We use precisely machined molds and perform in-process dimensional checks. Our TS16969 system includes statistical process control (SPC) to maintain tight tolerances.
- Q: Can I get a sample before placing a bulk order? A: Absolutely. We offer sample production with a lead time of 7–15 days. Sample costs are negotiable and refundable with bulk orders.
- Q: Which ports do you ship from? A: We ship from Jiangsu, Shanghai, or Shenzhen, depending on the order volume and destination. We also support door-to-door delivery for certain markets.
