Q2: How to increase the success rate of sample production ?

Update Time:2026/4/1

At FELIX GLASS, we know that the success rate of sample production is critical to your product development and mass production plans. A successful sample not only verifies product quality and performance but also lays the foundation for smooth mass production. Based on our years of experience in optical glass manufacturing, we have summarized the following key tips to help you increase the success rate of sample production, ensuring you get a sample that fully meets your requirements in one go.

1. Provide complete and accurate product specifications

The most important factor in sample production success is clear, complete, and accurate product specifications. You should provide as much detailed information as possible, including:

- Product type: optical dome, display glass, AR/AG/AF coated glass, tempered glass, etc.

- Material requirements: BK7, fused silica, sapphire, borosilicate glass, etc.

- Size, thickness, diameter, and tolerance requirements (critical for precision optical products)

- Coating requirements: AR, AG, AF, anti-UV, conductive coating, etc., and transmittance/reflectance requirements

- Processing requirements: drilling, etching, tempering, polishing, edge grinding, etc.

- Application scenario: automotive, medical, industrial, consumer electronics, etc. (helps us optimize the product design)

2. Provide detailed drawings or 3D files

If you have product drawings (2D CAD drawings, 3D STEP/IGS files), please attach them to your sample request. Drawings are the most direct and accurate way to convey product requirements, avoiding misunderstandings caused by text description. Our engineering team can directly use the drawings for sample production, ensuring 100% consistency with your requirements.

3. Communicate your core requirements and tolerance range clearly

Clearly inform us of your core functional requirements and acceptable tolerance range. For example, if you need an optical dome for a camera sensor, clearly inform us of the transmittance requirement, surface smoothness requirement, and impact resistance requirement. This helps our engineering team adjust the production process and material selection to meet your core needs, even if there are minor deviations in non-critical parameters.

4. Confirm the sample plan and quotation before production

Before starting sample production, we will provide a detailed sample plan, including product design, production process, lead time, and cost. Please carefully confirm the plan, ask any questions you may have, and confirm all details before production. This avoids rework and delays caused by requirement deviations after production starts.

5. Provide reference samples if possible

If you have existing reference samples, please send them to us (or provide clear photos and test data). This allows us to directly compare and replicate the sample performance, ensuring the new sample meets your expectations.

6. Cooperate with our technical team for communication

Our engineering team will communicate with you during the sample production process, confirm any unclear requirements, and provide professional suggestions. Please respond to our communication in a timely manner, and work with us to optimize the product design, ensuring the sample meets your requirements.

At FELIX GLASS, we have a professional sample production team and strict quality control process, ensuring high sample production success rates. We will provide sample photos, test data, and inspection reports before shipment, allowing you to confirm the sample quality before receiving it. We are committed to helping our customers achieve successful sample production and smooth mass production, supporting their product development and business growth.
