Precision Injection Molded Observation Windows – Engineered for RationalDMIS CMM & Industrial Measurement Systems
As a dedicated manufacturer with over five years of experience in precision mold making, Changzhou Hongxinyutai Precision Mold Co., Ltd. presents our high-quality transparent injection plastic windows specifically designed for CMM (Coordinate Measuring Machine) applications, compatible with RationalDMIS software environments. These observation windows are produced in our 1,000-3,000 sqm facility, leveraging advanced injection molding technology to achieve zero gas mark, crystal clear transparency, and tight dimensional tolerances. Built for demanding metrology labs and production floors, our windows ensure unobstructed vision and reliable part inspection without distortion.
Our clear plastic observation windows are available in both square and round shapes, tailored to fit various CMM enclosures, light curtains, or inspection ports. They are crafted from high-grade optical-grade polycarbonate or acrylic materials, offering excellent impact resistance and UV stability. The zero gas mark feature guarantees a bubble-free, streak-free surface that maintains optical clarity even after repeated cleaning or exposure to workshop environments.
Key Product Features & Technical Specifications:
- Zero Gas Mark Technology – Mold design and process optimization eliminate trapped air, resulting in flawless surfaces with no visible bubbles or flow marks.
- High Precision Dimensional Tolerance – Achieved through our TS16969 certified quality management system, typical tolerances within ±0.01mm for small parts, ensuring perfect fit into CMM frames.
- Excellent Light Transmission (>92%) – Optical-grade resin ensures minimal light scattering, critical for accurate visual inspection and measurement.
- Wide Shape & Size Options – Square windows (50x50mm up to 300x300mm), round windows (OD 30mm to 200mm). Custom dimensions readily available upon request.
- Surface Hardness & Scratch Resistance – Optional hard coating for enhanced durability in high-traffic areas.
- Compatible with Standard Frames – Designed to fit common CMM brands (Zeiss, Mitutoyo, Hexagon, etc.) and RationalDMIS software-based systems.

Frequently Asked Questions (FAQ)
Q1: Are these windows compatible with all CMM brands?
A: Our windows are designed with standard dimensions that fit most CMM enclosures (Zeiss, Mitutoyo, Hexagon, etc.). For non-standard frames, we can customize the size and mounting hole pattern. Please provide your frame drawing.
Q2: What does “zero gas mark” mean?
A: “Zero gas mark” refers to the absence of trapped gas bubbles or flow marks on the window surface. This is achieved by optimized mold design and process parameters, ensuring optical clarity and no distortion during measurement.
Q3: Can you provide windows with anti-reflective coating?
A: Yes, we offer optional anti-reflective and hard coatings to improve scratch resistance and reduce glare. Please inquire for specifications.
Q4: What is the typical lead time for custom windows?
A: For standard sizes (e.g., 100x100mm square), lead time is 5-7 working days. Custom shapes require mold modification and usually take 10-15 working days. Express production is available upon request.
Q5: How do you ensure the quality of each window?
A: We follow a strict quality control plan: incoming material inspection, in-process mold monitoring, and final inspection using CMM and visual inspection under controlled lighting. Our TS16969 certified system ensures traceability.
Q6: Do you ship to Singapore and other Asian markets?
A: Absolutely. We frequently export to Southeast Asia, including Singapore, Malaysia, Thailand, and Vietnam. Shipping time via sea freight is typically 7-14 days; express couriers take 3-5 days.
Q7: What is the minimum order quantity (MOQ)?
A: For standard products, MOQ is 100 pieces. For custom designs, MOQ may be 500 pieces depending on complexity. We also accept small trial orders for evaluation.
Q8: Can you help with design or material selection?
A: Yes, our engineering team can assist in selecting the optimal material (PC vs. Acrylic) based on temperature, chemical exposure, and optical requirements. We also offer DFM (Design for Manufacturing) feedback for cost reduction.
