Promaker believes that a focus on customer requirements gives us everything we need to know about improving product quality and service. Because of that, we use a 4S service concept: service, sales, survey, and standard production. After-sales service is a key part of that system, and to assist in our mission of expert customer service, we have 10 offices around the world, and customers that come to us from India, Turkey, Vietnam, and numerous Middle Eastern countries.
