At the commendation meeting of “Innovation and Outstanding New Products†recently held by China Machinery General Components Industry Association, the “hydraulic retarder†declared by Fast was awarded the “Outstanding Innovative New Product†special award, “S16 block series. "Transmission" and "7DS180 series mining car transmission" won the award for excellence. The hydraulic retarder is an auxiliary braking system developed by Fast Company to improve the safety performance of vehicles. It has advanced technology, stable performance, safety and reliability, good braking effect, lightweight design, more economical and environmental protection, and wide adaptability. The special vehicles for medium and large passenger cars, medium and heavy trucks, and mining vehicles are highly favored by market users. The number of possessions is growing rapidly. It has become the first brand of its kind in the industry and its market share has reached 80%. The S16 series transmission is the upgrading and updating product of the international advanced level designed and developed by Fast, and its performance index has reached the level of the same industry in foreign countries, and some performance indicators even surpass it. The product is suitable for heavy-duty trucks with engines of 375 horsepower or more. Currently, the heavy-duty trucks in the horsepower segment of the domestic market are gradually increasing. Fast's products fully meet the market demand, and the market supporting volume is rapidly increasing. The 7DS180 series mining transmission is a sincere product aimed at the market segments of Fast. Its main parts and components are all reinforced, with high reliability and large bearing capacity. Compared with the same torque section under special working conditions and road conditions in the mining area. With other brands of transmissions with a deputy box, the failure rate is greatly reduced. At the same time, it has its own forced lubrication system, which further increases the service life of the transmission and the attendance rate of the vehicle, creates additional value for the user, and has become the standard for the wide body mining dump truck. These three products won the honor of "Innovation and Excellence in New Products". It is a full recognition of Fast's commitment to innovation and focus on building Fast's brand for many years. It is also a great encouragement to the company's scientific and technical personnel. We have reason to firmly believe that, with the help of building an innovative country, Fast will further accelerate the pace of independent innovation and develop new products with independent intellectual property rights that are technically and comprehensively benchmarked internationally and with higher technological content, accelerating the internationalization of enterprises. The development process and extensive participation in international market competition injected new vitality.
Food Machinery Precision Casting or food machinery investment casting, silica sol process. It is a casting process with little or no cutting.
Cast food machinery is an excellent process technology in the foundry industry. Its application is very extensive. Food machinery cast not only applies to the casting of various types and alloys, but also produces the dimensional accuracy of castings. The surface quality is higher than that of other casting methods, and even castings that are difficult to cast and which are difficult to cast have high temperature resistance and are not easily processed can be cast using investment casting.
In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
In shell hardening process,we use aluminium chloride to harden the shell.This can make the shell so hard that it can`t be distorted,at the same time the bug which the casting may have will be decreased.If there are letters or numbers in it,they will be much clearer.
In dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing technics,but we using the advanced steam dewaxing technics,which we are very proud of. This can effectively avoid the air-hole and sand-hole, making the casting look much nicer.
In smelt process, we use middle frequency furnace, avoiding the emergence of the oxide; in molten steel control part, we use Germany-imported direct reading spectrometer machine, assuring its quality before the molten steel out of the furnace. During this process we use ERP production and management software to get the feedback information.
In shell-knock out process, we have special machines,which can decrease the hitting and knocking, easily made by manual shell knocking out.
In shot-blasting process, we have crawler-type and hanging shot-blasting machine, with steel shot 0.5-0.8, making the products smooth.Of course, if the customer wants it look much nicer, we also can carry out sand-blast treatment.
In heat treatment process, we use electric furnace, and adopt double-temperature control in order to heat the products equally. As a result, the products will have great metallurgical structure.
Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.
In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.
