Inquiry (采购产品): engraving technology Hi, we are a canadien company, working for a client in a developping country. We are looking for a technology to engrave, or mark a name or a code directly on a steel gas cylinder. The mark must be unremovable, and must not affect the resistance of the steel cylinder, which will be full of gas. Do you have such this technology?
