Product Questions and Answers

Q1: What are the differences between your plastic materials like acetate, TR90, and standard injection plastic (CP/PC)? Which one is right for my brand?

This is a crucial question for sourcing. Here’s a quick guide:

• Acetate is a premium, plant-based plastic known for its rich, layered colors and luxurious, solid feel. It's best for fashion-forward, boutique, and high-end optical lines where brand story and artisanal quality are key.
• TR90 is an ultra-flexible, lightweight, and impact-resistant Swiss polymer. It’s the top choice for activewear, children's eyewear, and performance lines where durability and comfort are paramount.
• Standard Injection Plastic (CP/PC) offers the best value and production consistency for large volumes. It’s ideal for major retail collections, price-conscious private labels, and promotional eyewear, providing good quality and a wide range of solid colors at a competitive price point.

We can help you select the perfect material based on your target cost, brand identity, and desired product features.

Q2. What is your Minimum Order Quantity (MOQ) for plastic frames, and is it flexible?
Ready-stock eyewear with logo customization start from 300 pcs on selected styles. OEM/ODM projects usually start from 600 pcs per model depending on customization level. However, we understand the needs of new projects and emerging brands. For special projects, we can discuss a more flexible MOQ. Our goal is to build long-term partnerships, so please contact our sales team to discuss your specific requirements.

Q3. Can you explain your quality control (QC) process for a bulk order of plastic eyeglasses?

Absolutely. Our QC process is integrated at every stage:

• Raw Material Inspection (IQC): We test all polymer granules for purity, color consistency, and durability before production.
• In-Process QC (IPQC): During injection molding and finishing, we constantly check for defects like sink marks, flash, or color variation.
• Final QC (FQC): Every single finished frame undergoes a comprehensive final inspection covering structural integrity, hinge smoothness, color accuracy, alignment, and cleanliness before it is packed.

Our factory is ISO 9001 certified, and we guarantee our products meet CE and FDA standards.

Q4. What is the typical production lead time for a wholesale order of plastic frames after I confirm the sample?
Our standard production lead time is approximately 15-35 days after the pre-production sample is approved and the deposit is received. This timeframe can vary slightly based on the complexity of the design and the order volume. For urgent needs, we can sometimes offer expedited options. We will always provide a firm delivery schedule when you place your order.

Q5. How do you ensure color consistency for large orders, especially with custom Pantone colors?

Color consistency is critical. We achieve it through a strict process:

• Master Batch Formulation: We work with expert color labs to create a precise "master batch" of polymer granules matching your Pantone reference.
• Controlled Injection Parameters: Our computer-controlled injection machines use consistent temperature and pressure settings to prevent color shifts.
• Spectrometer Checks: We use a spectrometer to digitally verify that the color of the produced frames matches the approved standard within a very tight tolerance. This ensures a frame produced on day 1 is identical to one produced on day 30.
  
  

Q6. What are my options for branding and logos on the plastic frames?

We offer several high-quality branding options to suit your design:

• Pad Printing: A precise and durable method for applying logos in single or multiple colors to the temples or lens.
• Laser Engraving: Offers a subtle, high-end tonal look, ideal for branding on the temple tips or for small, intricate marks.
• Metal Decal/Logo: For a premium touch, we can embed a custom-made metal logo plaque into the plastic temple.

We can provide mock-ups to help you visualize the final result.

Q7. Do you provide testing reports or certifications for your materials and finished products?

Yes, we provide full transparency and compliance documentation. Upon request, we can supply:

• Material Safety Data Sheets (MSDS) for the polymers used.
• CE Declaration of Conformity for entry into the European market.
• FDA Registration information for the US market.
• Specific test reports (e.g., for lead content, nickel release on hinges, or impact resistance) from third-party labs like SGS or Intertek, as required for your project.
