AMALPHA is our unique metal surface treatment technology for directly joining resin and metal. Resin and metal are joined at the interface level to create resin-metal integrally molded parts. It supports a wide range of molding technologies such as insert injection molding, transfer molding, and heat pressing. Direct bonding of resin and metal Amalfa treatment is a technology that forms micron-sized fine irregularities on the metal surface by chemical etching. When the resin enters these irregularities and hardens, a strong bond is realized by the anchor effect. How AMALPHA joins New functional parts created by Amalfa By joining resin and metal at the interface level, it will be possible to create parts with new designs and functions that maximize the characteristics of each metal and resin. Weight saving The weight of the parts is reduced by using metal for the parts that require strength and resin for the other parts. Airtightness / watertightness The resin and metal are in perfect contact and do not allow gas or liquid to pass through. Reduction of the number of parts Parts that are fastened with screws etc. are integrally molded into one part, reducing the assembly man-hours. Highly durable joint It has excellent durability because it does not use adhesive. The same joining life as the base material such as resin and metal can be obtained.
