To ensure the structure design is workable and can be fixed in the appliance properly, we’ll initially quick built a prototype once customer confirmed the drawing, prototype sample building is a very critical stage that bring customer conception into real products, customer will verify the function, structure, quality and other parameters of the sample according to the original conception requirements. Customer still have chance to revise the structure easily during this stage, injection mould will only start whenever customer confirmed on the final drawing, the revised units will be 100% meet customer’s expectation.
