Triennial Tokyo, Japan International Rubber & Plastic Exhibition, just held in Tokyo, Japan Mabi Makuhari International Pavilion end (2017.10.24 - 10.28), which is the world's third largest international rubber and plastic exhibition, second only to the three The annual K show and Chinaplas in China.
After three days of detailed observation, Dongguan Polytechnic Institute of Mechanical Engineering / Chang'an Institute of Advanced Manufacturing Associate Professor, ACMT Materials Science and Technology Committee Chairman / Vice Chairman of Powder Injection Molding Committee, Chairman of China Powder Injection Molding Alliance (PIMA-CN), Dr. Qiu Yaohong (Dr. Q) comes down to three important things:
1. Rubber & Plastics Industry Internet of Things (IoT, Internet of Thing) and 4.0 industry progress
2. Molds and equipment upgrades and improvements
3 automobile structure to plastic substitution steel trend
Through the eyes of Dr. Q, this essay will provide you with insightful explanations of the characters and patterns that are easy to read, as well as giving you a chance to visit without any chance of visiting.
ACMT visit to the factory in Japan depth of experience - like entering the home visit
In order to give members a closer presence, we arranged for a pre-meeting visit to penetrate two of Japan's strongest equipment factories - the SUMITOMO heavy machinery factory for traditional strength and SODICK, a young rookie, Kanagawa Plant The following is a summary of the characteristics of the two factories.
Sumitomo heavy machine - attention to detail of the traditional strength
The injection molding machine business started earlier with Sumitomo Heavy Industries, dating back to 50 years ago in 1966 and manufacturing technology shifted from the Swiss-based Nestal brand in Europe (currently Nestal has been acquired by KraussMaffei and KM). Sumitomo has been at least 15 years slower than Japanese injectors Shunsuo: JSW and NESSEI, but thanks to the hardworking and upward spirit of Sumitomo Heavy Industries' 300-year heritage in copper mining, Become famous brand injection machine in Japan.
Sure enough, the details of the Japanese factory immediately gave the members a special feeling, the delegation of nearly 50 people have at least 20 for the reception staff, from visiting the disposable shoe covers and disposable cap in hard hat dirt, old The factory was well-organized, with a list of all capable workers and technical expertise, as well as tool carts that were assembled from the most economical steel pipes and planks for each site.
Subic - the courage to create young rookie
Into the Subic factory, the reception staff is still more than 20 people outside, able to speak Chinese, Taiwan branch staff are also present, the most Dr. Q feel shock is the slogan: 'made their own Something that is not in the world ',' a machine that supports the progress of the manufacturing industry, and 'the future of the manufacturing industry is supported by new technologies.' 'The bright showrooms are home to a variety of innovative equipment and the ultimate products processed with these machines. SODICK Representative of the injection molding using V-Line way, this injection and Canada teach separation method to change the traditional injection molding, but also broke through when the injection machine killings in the sudden breakthrough in the design, enough to prove that Subic had the order (2), the separation function makes the plasticizing process can be more smoothly without causing too much friction, the screw does not have a rocket but only less wear and tear to improve life expectancy, material cutting time is shortened and will not cause excessive friction, Long life of the injection piston and other advantages, it is impressive Subic creativity and practice.
IPF Visit by ACMT Delegation - Comprehensive Experience
Our vast readership based on service (ACMT Members Daily Daily Addendum Daily Daily Report), other industry-similar platforms and schools, in particular, pick out more important items from Members' Addendum Report to share with you here.
1. Rubber and plastic industry combined Internet of Things (IoT) and 4.0 industry progress
At last year's German show, we already saw the two-dimensional bar code on the mold, and each product has been able to check the production information. In IPF exhibition booth, the request of all-things interconnection has caused the auto-stick bar code Machine, and the serial number of the bar code is unique, then how to do with smaller parts of the bar code with a serial number?
The use of printing droplet dislocation principle so that each one can not be the same droplet, the use of inkjet recording inkjet images (drop point, color, dot area, etc.), through a specific scanner or even use a smart phone camera Scan, you can track to the product.
2. Molds and equipment upgrades and improvements
Speaking of mold technology than metal 3D printing is used to manufacture plastic mold, which can be made into the water system (Conformal cooling system) inside the module, as shown in Figure (4), in addition to doing previously impossible twists and turns Of the waterway, but also the water from the circular cross section into a flat cross-section to reduce the water cooling area, and reduce the waterway occupied space and volume, so that the mold structure more solid.
Public printing technology and OPM-SODICK CNC machining is the most advanced composite 3D printing technology, OPM Institute was originally only a small laboratory, led by Mori Mori, director of metal 3D printing to the extreme, which led to the final by SODICK bid to OPM laboratory technology bought, into a positive result. OPM's CNC machining composite 3D printer features:
n intensive take-off starting from the fifth floor (each layer is 0.2mm, five 0.2mm ⅹ 5 = 1mm), not more than 5 layers, at least 3 layers, in order to avoid high-speed CNC milling cutter cutting too much;
n finishing tool cutting material is less than 0.1mm, in order to extend tool life;
nIn order to prevent the tool from jumping, the OPM finishing process will suck the powder beside the contour, and then make up the powder as the support.As shown in the figure (5), this is the patented feature of OPM;
n process soot are protected atmosphere quickly take away the airflow to prevent contamination of the powder, the use of residual powder must be screened, not directly reused.
In addition, we also see the rapid refueling (injection Friends injection machine) system and fiber pre-barrel system (many), due to the addition of additives (toner, fiber, ore, etc.) An optical detector feedback to see if the compound is homogeneous enough to switch additives without cooling down is a highlight of the injection molding technology used at the facility, using mechanisms that change the most for operator headache Of operations, has been greatly improved, as long as the basic raw materials remain unchanged, additives can be arbitrarily changed.
We also saw the improved equipment for the direct injection of colloidal particles without baking. The improved design of the Nippon Oil Company makes it possible to start injection of certain materials without baking. The principle is very simple, that is to design a group and two sections Pressurized screw and improved barrel, the quantitative control of the raw material drop by the first paragraph of the pressure forward squeeze, and then after a period of relaxation space, the previous period of heated particles in the rubber will be released from the middle of the barrel deflate valve Discharge, and then through the normal pressure dose to complete the injection.
We also found several large car enclosures on site. The ICC (Innovation Composition Center) assembled all the companies that developed carbon fiber materials in Japan to brainstorm together. In order to make the next generation of lightweight cars, Large and attractive .Finally known carbon fiber reinforced plastics (CFRP, Carbon Fiber Reinforced Polymer) and carbon fiber reinforced plastic (Carbon Fiber Reinforced Thermo-Plastic), from the past must be used in a layer of vacuum deposition after the attachment to the available spray , Injection molding methods to continuously improve its manufacturing efficiency, in response to production capacity and output needs.
in conclusion
We need to reflect on why Japan can create? And we can not do it. I am afraid that most people in our country can see it, but we have seen very few people put it into operation. We have invested money and started to work on it. I believe this is catching up with Japan over the world First-class maximum capacity.
