This project is one of the scientific and technological achievements of Bochuang and Huagong's winning project in the 2003 major equipment technology innovation project in Guangdong Province--"High-speed and high-efficiency integrated precision injection molding equipment" project, since the project began research and development, in Guangdong Province With the strong support of the Economic and Trade Commission, Borch has combined the rigorous theoretical research and the research results of major technical performances of South China University of Technology with the needs of its own production system and customers in the injection molding machine industry to realize a series of commitments during the bidding.
The appraisal committee heard the trial production and production report of the products of South China University of Technology and Guangzhou Bochuang Machinery Co., Ltd., carefully reviewed the technical documents and materials provided by the appraisal and the test report of the National Plastic Machinery Product Quality Supervision and Inspection Center. The operation of the BT80V prototype machine of the system has been configured on site. After careful discussion and discussion, it is believed that the performance parameters of the product meet the requirements of the plan and the relevant standards, and are well reflected by the users.
This product introduces the vibration force field into the whole process of polymer injection filling, which has obvious technical innovation, and its technology is at the domestic leading level. Bochuang's production equipment and process equipment are advanced, the testing methods are complete, and it has the mass production conditions.
Self-Shielded Flux Cored Wires
Self-Shielded Flux Cored Wires:
The self-shielded Flux Cored Wire protects the molten droplet and molten pool through the gas and slag produced by the slag-forming agent and gas-generating agent in the flux core of the welding wire under the high temperature of the arc.
The self-shielded flux-cored arc welding method has the following advantages:
1. No external protective gas source is needed, the welding torch is simple in structure, light in weight, and easy to operate;
2. The performance of wind resistance and porosity is good. During welding, the metallurgical reaction of the welding wire itself forms a protective atmosphere. It can be welded under the fourth-level wind force. As long as the wind speed does not exceed 8m/s, no protective measures need to be taken. It is especially suitable for Field construction work;
3. The arc penetrating power should be large, the molten drop should be in the form of jet transition, and the splash should be small;
4. It has excellent all-position vertical down welding operation process performance, and the operation process performance is good;
5. Good slag removal performance;
6. The deposited metal can also obtain high low temperature toughness under various harsh conditions such as low temperature and strong wind.
Self-shielded flux cored wire is widely used in pipeline construction, marine engineering, outdoor large-scale steel structure manufacturing, high-rise steel structure buildings, surface surfacing, etc.
