Donald Gonzalez

Donald Gonzalez

Donald Gonzalez has over 40 years of experience in the mold polishing field. He started his apprenticeship in 1979 at Caco Pacific and moved to Kipp Group Medical Products where he worked for 11 years. He then went on to start his own mold polishing business, DG Mold Polishing, which he currently runs today with his family. Donald loves working with people and teaching them new techniques to the trade. One thing he loves about our ultrasonic polishing machines is how easy they are to use especially for polishing tight areas such as ribs, sidewalls and small details. Donald believes that there will always be a need for polishers in the mold and die industry.

Steve Smith

Steve Smith has over 45 years of experience in mold polishing. He first began polishing at Wilkin’s Mold Polishing, which was the only mold polishing shop in the western part of the United States that trained polishers. In 1979, he went on to become the Mold Polishing Supervisor at Caco Pacific, where he worked for the remainder of his career. Steve now enjoys all the interaction he has with the students at our mold polishing classes and helping them learn how to work more proficiently to become even better polishers. One thing he loves about our ultrasonic polishing machines is how helpful they are on Sinker EDM.
