Demand Analysis

Clearly understand your objectives and product specification requirements, we collect information and do analysis, including functional requirements, quality performance, appearance requirements, cost objectives, etc.

Concept Design

At conceptual design stage, the concept is generated from a number of design proposals after initial evaluation and selection. We provide professional technique and suggestion to help you choose the best solution.

Technical Assessment

To shorten the product development schedule, we conduct a technical evaluation on each concept design, including feasibility analysis, technical risk assessment, and cost analysis. This helps determine which solution is most suitable and effectively.

Engineering Design

After the conceptual design is determined, our R&D team will further design and implement various functions. We will use CAD software for 3D modeling and design documentation, including detailed component design, complete design drawings, engineering specification structural analysis, material selection and supply chain planning.

Prototyping

We provide complete prototype manufacturing equipment, and once the engineering design is completed, we will make prototype based on the design documents. Prototype is used to verify the appearance, functionality and performance of the product. As needed, we can make multiple prototypes for testing and improvement.

Test Evaluation

Test and evaluate prototype to ensure it meets your requirements and relevant standards to verify product functionality, appearance and performance. In this way, we can consolidate product quality and performance meet expectations.

Revision and Optimization

We conduct modifications and optimizations according to the results of verification and testing. This may involve redesign, material replacement, or process improvements.

Mold design & Mold validation

The mold stage requires precise processing equipment and process control. The completed mold gets through a number of trials. Besides, precision measuring instruments are used to check the size, appearance, surface quality, structural integrity, etc. so as to ensure that the mold meets acceptance of relevant quality standards and specifications.

Processing Technology

Post-processing of injection parts is performed to meet design requirements and improve their quality and appearance. Grinding and sanding are important steps in the frame/ temple. Using different grinding tools and abrasives, the frame/ temple are precisely ground and sanded to remove surface unevenness, gate and ejector pin imperfections, and achieve a smooth and refined appearance.

Product Inspection and Customer Acceptance

Inspection reports prepared, record the inspection process in detail, and conduct final product acceptance procedures with you.

Production and Delivery

According to the production plan, mass production begins and the final product is delivered.
