The number of products soft tooling can produce is generally 50-5000 pieces, for tens of thousands or even hundreds of thousands of products, we still need the traditional steel moulds. Hard tooling refers to the steel mold. The main methods using RPM prototype for steel moulding here in KAIAO are as follows: investment casting, Spark Erosion Machining , ceramic-type precision casting.

Hard tooling is kind of rapid tooling.

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.
