China Shipbuilding Heavy Industry News, a few days ago, Dalian Marine Diesel Engine Co., Ltd. 6S50MCC host successful inspection, which is the company in the current year in hand over 101 hosts, for the first time to achieve an annual output of one hundred hosts. At this point, Dalian Shipai achieved the first victory of the " Twelfth Five-Year Plan" with the construction of 101 units /1.63 million horsepower and an impressive 32.9% increase in the number of machines .
Asbestos was added as an common ingredient to Brake Pads post-WWI, as car speeds began to increase, because research showed that its properties allowed it to absorb the heat (which can reach 500 °F) while still providing the friction necessary to stop a vehicle. However, as the serious health-related hazards of asbestos eventually started to become apparent, other materials had to be found. Asbestos brake pads have largely been replaced by non-asbestos organic (NAO) materials in first world countries. Today, brake pad materials are classified into one of four principal categories, as follows:
Non-metallic materials - these are made from a combination of various synthetic substances bonded into a composite, principally in the form of cellulose, aramid, PAN, and sintered glass. They are gentle on rotors, but produce a fair amount of dust, thus having a short service life.
Semi-metallic materials - synthetics mixed with varying proportions of flaked metals. These are harder than non-metallic pads, more fade-resistant and longer lasting, but at the cost of increased wear to the rotor/drum which then must be replaced sooner. They also require more actuating force than non-metallic pads in order to generate braking torque.
Fully metallic materials - these pads are used only in racing vehicles, and are composed of sintered steel without any synthetic additives. They are very long-lasting, but require more force to slow a vehicle while wearing off the rotors faster. They also tend to be very loud.
Ceramic materials - Composed of clay and porcelain bonded to copper flakes and filaments, these are a good compromise between the durability of the metal pads, grip and fade resistance of the synthetic variety. Their principal drawback, however, is that unlike the previous three types, despite the presence of the copper (which has a high thermal conductivity), ceramic pads generally do not dissipate heat well, which can eventually cause the pads or other components of the braking system to warp.However, because the ceramic materials causes the braking sound to be elevated beyond that of human hearing, they are exceptionally quiet.

In 2011 , Dalian Shipai in accordance with the relevant strategic deployment of the group company, focusing on the development goals of the “ Twelfth Five-Year Plan†, adhere to the road of total assembly, specialization and large-scale development, further increase the research and development of technology, and allocate resources through scientific allocation. Effectiveness, making production factors fully effective. Through the structural adjustment of the production mode, the process flow is further rationalized, the modular assembly of the mainframe is implemented, and the construction cycle is shortened. Further improve the quality awareness and quality of all employees, strengthen process control, reduce costs, improve product quality, and continuously enhance the ability to meet the needs of new and old customers.
 In terms of production, Dalian Shipai's implementation plan pulls management, strengthens the forward-looking management of key and assembly (packaging) components, implements each specific component, realizes precise control of node projects, and ensures that the assembly progress of the host is balanced and orderly and steadily . In terms of supporting facilities, as some supporting enterprises can't keep up with the development speed of DMD , the company convened relevant leaders of the delaying units to hold special meetings, and solved a series of delays and difficulties in ensuring the production demand through a series of measures such as dispatching special personnel and regular inspections. . At the same time, the company also strengthened internal information exchange, communication and feedback, and vigorously promoted the host internal test program, and implemented the host's pre-shipment confirmation system. After-sales service personnel bring the sweeping confirmation sheet to the ship for after-sales service, which realizes the close connection between the company's internal and external sweeping work. Dalian Shipai also implemented the standardization and delivery of the mainframe to provide customers with excellent and rigorous products and services. While improving the quality and efficiency of the main engine delivery, it greatly facilitated the shipyard to pick up the aircraft. It has been highly evaluated by several shipyards, making the DMD brand Further brighten in the downturn of the ship market.
