The role played by rapid prototyping technology for moulds

Mold manufacturing rapid prototyping technology also plays an important role in the increasingly competitive market economy, mold manufacturing rapid prototyping technology also plays an important role, is an important part of the advanced manufacturing technology group. It concentrates computer-aided design and manufacturing technology, laser technology and material science and technology, in the absence of traditional molds and fixtures, rapid manufacturing of arbitrarily complex shapes and has a certain function of three-dimensional solid model or parts, about the cost of new product development and mold manufacturing, repair. Section applications in aviation, aerospace, automotive, communications, medical, electronics, home appliances, toys, military equipment, industrial modelling (carving), architectural models, machinery industry and other fields. In the mould manufacturing industry using rapid prototyping technology to make rapid prototypes, combined with silicone moulds, metal cold spraying, precision casting, electroforming, centrifugal casting and other methods to produce moulds.

So what features does it have? Firstly it uses a gradual increase in material (e.g. solidification, welding, gluing, sintering, polymerisation, etc.) to form the required part appearance. As RP technology does not produce waste during the manufacturing of products causing environmental pollution, it is a green manufacturing technology in today's contemporary eco-friendly world. The second is for a number of technologies such as laser technology, CNC technology, chemical and material engineering, which solves many of the problems in traditional processing and manufacturing. Rapid forming technology is widely used in China, for the development of China's manufacturing enterprises to play a supporting role, to enhance the rapid response to the market, improve the competitiveness of enterprises, but also for the national economic growth has made a significant contribution.

The advantages of 3D printing hand board model

  1. Good complex manufacturing capability, can complete the manufacturing of traditional methods difficult to complete. Product complexity, development only through multiple rounds of design - prototype production - test - modify the design - prototype re-production - re-test process, through the prototype repeat test in order to find problems and correction in a timely manner. However, the output of prototypes is extremely small, and the time and cost of using traditional manufacturing methods is long, resulting in long development cycles and high costs.
  2. low cost, fast, can significantly reduce the development risk, shorten the development time. 3D printing hand plate does not need the traditional manufacturing method of casting ingots, embryo, mould, die forging and other processes, can be fast, low-cost prototype production, and the entire production process digital, can be corrected at any time, at any time manufacturing, in a short period of time to carry out a large number of verification tests, thus significantly reducing the development risk, shorten the development time. This significantly reduces the development risk, shortens the development time and reduces the development cost.
  3. High material utilisation rate, which can effectively reduce production costs. Traditional manufacturing is "reduced material manufacturing", by cutting, extrusion and other operations on the raw material blanks, the excess raw materials removed, processing the required part shape, the process of removing the raw materials difficult to recycle, raw material waste is serious. 3D printing only add raw materials where needed, the material utilisation rate is very high, can This enables the use of expensive raw materials and significantly reduces costs.
