At Hejia Tech, we understand that every project is unique. When standard products don't meet your specific requirements, our Drawing Customization service allows you to turn your designs into finished lighting products — with precision, quality, and efficiency.

How It Works

Step 1: Submit Your Drawing

Send us your technical drawings, CAD files, or detailed sketches. Include specifications such as dimensions, materials, wattage, color temperature, waterproof rating, mounting method, and any other critical parameters.

Step 2: Engineering Review & Quotation

Our technical team reviews your drawing, evaluates feasibility, and provides professional feedback. We'll confirm material options, production methods, lead time, and a detailed quotation within 2–3 business days.

Step 3: Sample Production & Approval

Once the quotation is confirmed, we produce a prototype based on your drawing. Sample delivery typically takes 7–14 days depending on complexity. We provide photos, videos, and test reports for your remote approval before mass production.

Step 4: Mass Production & Delivery

After sample approval, mass production begins. Each batch undergoes strict quality inspection before shipment. Standard lead time: 2–4 weeks depending on order volume and product complexity.
