"Apart from the rest, three sentences are inseparable from the bank, we only talk about technology." Shanghai Yuanyuankang Group Co., Ltd. focuses on the current manufacturing of extruder heart parts in the industry. There are still problems such as backward technology and outdated equipment. Research and development of high-grade wear-resistant and corrosion-resistant alloy materials, engaged in research and development of new materials hardening process and high-precision molding processing methods.

For the current manufacturing of the heart parts of the extruder in the industry, Shanghai Yuanyuankang Group Co., Ltd. still generally has the contradiction of backward technology and outdated equipment. At the expense of capital, it has created a new generation of manufacturing and assembly precision of inner liners. A new generation of quality oval barrel liners for combined barrels has now become the first choice for high-end users in the harsh conditions of compounding and modification.

As a group company, it is mainly divided into two factories. The Anhui factory mainly produces more types of bimetal barrels and bimetal screws with wear-resistant and corrosion-resistant alloy layers, while the factory in Shanghai is more engaged in the development of high-grade wear-resistant and corrosion-resistant alloy materials. For the development of new materials hardening technology and high-precision molding processing methods. 【detailed】

Porous ceramic bushing barrel coming soon

Yuan Yuankang will mainly promote ceramic bushing barrels this year. The injection machine ceramic barrels developed by Yuan Yuankang Group have been successfully applied by companies such as Foxconn. Parallel double-hole bushings have also undergone three to four years of research and development and are in trials. During application. Ceramics are used as barrel linings, and their friction and wear resistance and corrosion resistance are beyond doubt.

Ceramic as the inner bushing, its own thermal conductivity is very important. The polymer material is plasticized in the barrel, and the main heat source is taken from the inner wall of the barrel. 【detailed】

How to solve the thermal conductivity and brittleness of ceramics?

Ceramics, such as their silicon carbide series, have many formulas as well as metal materials. Different formulas have different physical properties. As we all know, ceramic bearings made of ceramics are no longer rare in the market, so there is no need to worry about brittleness. The silicon carbide composite ceramic formula developed by us has quite high toughness. In addition to theoretically obtaining the toughness value of the material, we also mainly give users a trial. We choose compound extrusion conditions with large shear forces and large back pressure to examine the practice for a period of time, and look at the double holes. Whether the two sharp corners of the inner hole of the ceramic bushing can withstand strong shear forces, can the successful application of the user prove the ultimate success of the research and development.

So first of all we have to overcome these problems, all research and development need to first focus on solving ceramic brittleness and heat conduction. If these two points are done, its anti-corrosion and anti-wear properties can be magnified in the field of extrusion. 【detailed】

What are the valuable properties of ceramic materials? How does its cost compare to ordinary metal barrels?

The silicon carbide (SiC) composite ceramics developed by our company have excellent anti-friction and wear properties, and the material "self-wetting" is quite good. This is any metal-based material, even through a variety of hardening methods. SiC composite ceramic has more excellent chemical stability, and it can withstand almost all the corrosion of inorganic acids, alkalis and salts. The SiC composite ceramics we developed can also resist the corrosion and abrasion of hydrofluoric acids to a certain extent.

In terms of cost, unilaterally, the manufacturing cost of the "tall and tall" ceramic barrel is certainly higher. Our goal is this price-performance ratio. The ceramic bushing barrel and ceramic oval inner bushing we developed should be used under the same conditions of extreme friction and wear and corrosion and wear as those made of ordinary metal materials. Low, unique and better, should be more welcomed by users. 【detailed】

At this year's Adsale exhibition, Yuan Yuankang's ceramic barrel was officially unveiled. At the same time, the company also exhibited a product that was successfully developed in 2014 and comparable to the German W & P company's 99.3 material oval sleeve, which is specially designed to deal with high proportion glass fiber reinforced compounds. The high-vanadium cast iron Ω102A and Ω103A elliptical inner bushings under working conditions will also share the user experience report to the visitors at the exhibition.

Shanghai Yuanyuankang's ceramic bushing barrel has received a strong response after being used under the severe corrosive conditions of Foxconn Company, and has won high praise. In 2012, it won the Ringier Innovation Award. General Manager Wu said: "The successful use of Foxconn is a great incentive and spur to our staff in developing new materials." [Details]

What are the advantages of choosing an aluminum alloy manufacturing process with a lower cost coating on the periphery of the ceramic bushing?

First, reducing the consumption of relatively expensive ceramic materials; second, reducing the cost of elliptical machining outside the oval bush; third, optimizing the thermal conductivity of the ceramic bush, and fourth, facilitating the manufacturing of the positioning holes of the bush.

  

With the belief of "doing one thing for a lifetime", in the early years, Mr. Wu, who first developed a bimetal barrel and a bimetal screw in China, settled down in the vast ocean to know the core components of the extruder. The service life of the products in the showroom is the announcement of new materials for the core components of the extruder.

"The book fancier must work, and the art fancier must be good." The unremitting efforts of Shanghai Yuanyuankang Group in the research and development of materials and processes have made outstanding contributions to the sustainable development of the plastic compounding industry.

    [Editor's Conclusion]

    Many users praise Mr. Wu: "It's really not easy, just do one thing in a lifetime".

    President Wu commented on himself like this: "In my whole life, look back and see if I have done something beneficial to society. This is important, I believe in it. When I was young, I decided to stay in China because of this matter. Only half done, and I want to continue. " [Detailed]
