BTMT values efficiency. The traditional optical processing process usually takes 4-6 weeks, which is particularly limited when customers have urgent needs. Relying on deep industry experience, advanced production equipment, world-class testing equipment, excellent professional team and efficient management system, BTMT optimizes the production process, completely subverts the industry’s regular cycle, and targets small batches and high-precision customized products. We are able to provide "7-day delivery" featured service. The entire process only takes 7 days, starting from receiving the customer's order, going through the preparation stages of drawing, process, tooling, materials, etc., to processing procedures such as coarse and fine grinding, polishing, coating, edging, gluing, and final inspection, and then packaging and delivery to customers. This special service fully meets customer needs for emergency products and rapid research and development.
