Our service
Firstly, our sales engineering team will contact you for deep discussions about the design and product application(Like tablet, appliance, vendor machines), philosophy, target cost and performance requirements(IK, scratch resistance, surface quality, optical performance, etc).
Professional Advice: Based on your ideas, we provide material selection recommendations such as:
Chemically Strengthened Glass: We recommend brands such as Corning® Gorilla® Glass, Schott Xensation®, and AGC Dragontrail®, or materials like soda lime glass, high-aluminum/lithium aluminum-silicon high-performance glass.
Optical Coating Solutions: We recommend suitable AF (anti-fingerprint), AR (anti-reflective), and AG (anti-glare) coatings.
Value: We help you select the most cost-effective solution, avoiding issues in later mass production due to inappropriate material selection.
DFM (Design for Manufacturability) Analysis
Content: After you provide 2D/3D drawings, our engineering team will conduct a complimentary DFM analysis. We'll provide professional optimization recommendations for CNC cutting, hole location, edge chamfer, glass thickness, tolerance and other aspects to ensure maximum manufacturability, qualify rate and efficiency.
Value: Prevent risks from the design stage, shorten the development cycles and save potential costs.
Fast Prototyping and Sample Verification
We offer rapid prototype production services, covering the entire process from CNC shaping, polishing, chemical tempering, silk screen printing, to lamination, coatings and other processes. This ensures you can verify the product's appearance, quality, and assembly dimensions early in the project.
Value: "What you see is what you get," giving you full confidence before committing to mass production.
Accurate Quotation and Project Planning
Content: Provide a detailed, transparent, itemized quotation. Based on sample feedback, develop a clear project development timeline, clearly identifying key milestones.
Lean Production and Transparent Communication
Goal: Ensure a controllable and transparent production process, consistent and reliable product quality.
1. Order Management and Production Planning
Description: Each order is assigned a dedicated project manager, serving as your single point of contact. This manager will monitor the order status throughout the entire process and provide real-time updates on production progress.
2. Full-Process Quality Control (IQC/IPQC/OQC)
Content:
Incoming Material Inspection (IQC): Glass substrates are rigorously inspected to ensure they are free of scratches, bubbles, impurities, and other defects.
In-Process Inspection (IPQC): 100% or spot inspections are conducted after each critical process, including CNC machining, polishing, tempering, screen printing, and lamination, to monitor dimensions, chipping, strength, white spots, and contamination.
Outgoing Quality Control (OQC): Final inspection of finished products to ensure they meet your appearance standards, dimensional tolerances, and performance requirements.
Value: Build a comprehensive quality firewall to prevent defective products from reaching the next stage.
3. Key Process Control and Data Traceability
Content:
Chemical Strengthening Control: Strictly monitor the tempering furnace temperature, time, and salt solution composition to ensure stable and standard flexural strength and surface compressive stress (DOL/CS values).
Screen Printing and Lamination: Control ink thickness and adhesion, and ensure OCA adhesive lamination is bubble-free and dust-free.
Data Traceability: Establish a batch number management system to ensure full product traceability from raw materials to finished product.
Value: Process stability is the foundation of product consistency, and data traceability provides strong support for problem analysis.
4. Packaging and Logistics Management
Details: Customized export boxes with anti-static, shockproof, and dust-free packaging are used to protect the glass from scratches and breakage during transportation. Flexible logistics solutions are also provided.
Quick Response and Continuous Support
Goal: To establish long-term partnerships and provide worry-free after-sales service.
1. Rapid Complaint Response Mechanism
Details: We have established a dedicated after-sales service email address: qa@dgglbl.com. We promise to respond to customer feedback within 2 business hours and provide an initial solution within 24 hours.
2. Customer Complaint Analysis and Return and Exchange Policy
Details: We offer a convenient return and exchange service for issues confirmed to be our fault. Our quality engineers will conduct a root cause analysis (RCA) and provide you with a detailed Quality Issue Analysis Report and Corrective and Preventive Action Plan (CAPA).
3. Collaborative Quality Improvement
Content: Regularly conduct quality reviews with customers, share production data and quality trends, and jointly discuss and implement continuous improvement plans to help you continuously improve the qualify rate and reliability of your end products.
4. Long term Technical Cooperation and New Product Support
