Design, manufacture a auto parts moulds, fastest need how long? If it's traditional for two months, or even half a year, it's a little bit "out".

Founded on Friday, ruian auto parts rapid manufacturing technology public service center's answer is: the fastest half a month.

"Rapid manufacturing, is the use of 3 d printing, 3 d drawings print directly into the product." In the words of ruian technology bureau deputy director NiYongSheng, can the center through the rapid design, rapid molding, rapid prototyping, rapid detection, short time as possible, a car parts of the design ideas, print into products.

Well, where are the secrets of rapid manufacturing, to specific application in the field of what? The reporter comes to explore public service center.

Mock-up scanned into 3 d drawings

Finish the 3 d printer immediately

The advent of a new product, the key lies in the design and modeling. In rui Ming industrial co., LTD. Is located in wenzhou's rapid manufacturing in the public service center, the first step of rapid manufacturing is the rapid design.

, unlike traditional drawing and modeling of top-down design, USES a reverse engineering design center, or get a product with a laser scanner to get point cloud data, and then through the point cloud data to reconstruct 3 d data. That is to say, simply by scanning mock-up, can mapping.

Rui Ming said Han Jian executive director, the use of reverse engineering design technology, center can now carefully analysis was carried out on the physical parts, high efficiency and high precision to extract the 3 d data, thus forming the drawings. Generated 3 d drawings, technical personnel will be data to 3 d printers, printing material, and then packed to start the printer can achieve rapid manufacturing.

In rapid tooling manufacture center, the reporter saw a nearly two metres tall, shaped like a clothes closet. Han Jian introduction, this is a used laser sintering technology of rapid prototyping machines, also is the 3 d printer.

In a square piece of test pieces, for example, the big iron box nearly two metres tall, with powder roll back and forth movement, the raw material powder evenly spread on metal platform, from the top circular device and the laser beam on the thin layer of powder and "walk", next to the screen shows the three-dimensional structure of the parts is a bit "growth".

Technical staff, told reporters that brown powder is the resin sand production mold material, under computer control, laser scanning of resin sand will solidify, scanning, curing time and again, again and again under the action of laser between layer and layer implements the accumulation, step by step a seamless connection. It's like trying to make the cake pouring cream the layers.

Rui Ming main engine cylinder head, for example, first through reverse engineering design technology, after 3 hours, scanning, reconstructing 3 d data of cylinder head. Technical personnel according to the different needs of enterprises, to modify drawings and improvement, reusing data in 3 d printer model rapid manufacturing. After molding, and then with other components of the test and assembly, after successfully trial-produced can realize batch production.

Rapid manufacturing is still in the stage

The market foreground is incalculable

Using rapid technology, rui Ming was the first to taste the "sweet". "Previously developed a cylinder head need 5 months time, now two weeks can be completed, the costs are from hundreds of millions of yuan to hundreds of thousands of yuan." Han Jian said, rapid manufacturing technique can shorten the development cycle of manufacturing of new products, also can reduce development costs.

In addition, in the field of traditional automobile manufacturing, auto parts mold parts development often need long time of research and development, testing. When there is a problem, revised parts also need the same long cycle. While the 3 d printing can quickly make modelling complex parts, when test problems, modify the 3 d files to print can test again.

According to introducing, at present many support 3 d printing materials. Resin, nylon, plaster, plastic these are commonly used materials, along with the advance of research and development of the industry, support of titanium, stainless steel or aluminum, iron metal printer also has emerged.

"Although the center located in rui Ming, but not the workshop or department of an enterprise, but is an independent public service platform." NiYongSheng told reporters that the center guided by government, business investment, a market-oriented operation, is geared to the needs of the whole city motors, pumps, machinery manufacturing enterprises of science and technology innovation public service platform.

He told reporters that the current ruian for automobile, electronic, plastic, shoe, crafts and other pillar industries of 60% parts by mold to finalize the design, overall development level is low, but the mold and die industry has become the bottleneck of restricting the transformation and upgrading of industry. Rapid manufacturing center after the establishment of public services, is committed to advanced rapid prototyping technology can be incorporated into various industries in the rapid development of new products, establish enterprise product rapid development of digital service platform, drive the surrounding enterprises to accelerate the product development process.

In the formal putting-in-service proactively on the same day, ruian technology bureau has issued to sign enterprises technological innovation public service voucher, coupon redemption of enterprises can enjoy a 15% to 15% within three years of machining allowance. At the same time, the center also with gac group, zhejiang geely holding group, force state, and wins HuaBo 4 companies signed a cooperation agreement.
