In epoxy moulding, there are a variety of processing methods developed according to the cost, materials, precision requirements, batch etc. Experts say the current rapid tooling methods are roughly indirect molding and direct molding. The method based on rapid prototyping is mainly indirect molding and the mold produced are bridge tooling and soft mold and hard mold.
Bridge tooling usually refers to the direct injection molding of epoxy resin mold. When compared with traditional injection molding, epoxy moulding costs only a fraction of the traditional method and the production cycle is also greatly reduced. The die life, up to 1000 ~ 5000 pieces, is shorter than steel hard mould, but it is longer than the silicone molds, which makes it possible to meet the needs of small and medium volume production.
A lot of enterprises in Shenzhen, the center of moulding in China, has made a lot of progress in the rapid tooling. KAIAO, as one of the star enterprises in rapid prototyping, has accumulated a wealth of experience and establishes a long-term relationship Foxconn, Chana Auto, Motorola etc. and are winning more customers
Generally, rapid prototyping uses solid model (master mould) to copy (such as metal spraying, electroplating, composite casting, casting, etc.) to quickly create the main mold parts (convex, die or mold cavity, core), and its manufacturing cycle is about 1/5 to 1/10 of CNC machining, while the cost is only 1/3 ~ 1/5.
Rapid Tooling is the bottlenecks and key that restrict the development of China’s automobile, home appliances, light industry and other industries. With the continuous development and improvement in hardware and software equipment of rapid prototyping, the strength and accuracy of parts from rapid prototyping continues to improve. Rapid Prototyping has been gradually deep into the field of rapid tooling. Simple economic fast molds based on rapid prototyping specially epoxy mould has become a hot topic.
Epoxy mold is more and more widely used and further promotes the rapid development of rapid tooling, which also helps new research and development in cars and home appliances on the market.
