At present, the scale of investment in fixed assets in the province has grown considerably compared to last year, and investment in infrastructure has increased steadily. In addition, large- and medium-sized construction projects and infrastructure projects have started to increase substantially. Right now, local investment in the transformation of â€œold citiesâ€ in the large and medium-sized cities of the province and reconstruction of public facilities has continued unabated. The process of housing reform in cities and towns has been accelerating, farmersâ€™ housing concepts have been updated, and more and more rural households have invested in the construction of new houses, prompting an increase in the area of â€‹â€‹urban and rural housing construction. In order to increase production capacity, engineering construction units are eager to buy construction machinery.
Seen from the specific varieties, the demand for large and medium-sized wheel loaders, bucket hydraulic excavators and wheeled scrapers has steadily increased, and brand-name products are particularly popular. The urban and rural housing construction has been accelerated. The demand for steel prefabrication machinery, concrete mixers, high-rise building foundation drilling machines, electric floor tile cutters, paint sprayers, aluminum presses, tower cranes, hangers and parts has been greatly increased. Favored. The rapid development of urban and rural highway networks has increased the demand for road rollers, highway asphalt pavers, cement mortar shakers, wheel bulldozers, Dongfeng, Liberated dump trucks, concrete pump trucks, and large-scale automobile cranes; The demand for auto hoists and various types of traditional hoists below 5 tons has slowed down, presenting an oversupply situation. The demand for special machinery for the construction of sanitation, gardens and bridges is increasingly promising. Construction and construction machinery produced by well-known township and township enterprises had poor quality of some products, and despite the sudden price drop, no one was interested. Some advanced technologies with advanced international standards, modern construction machinery are favored, but the supply is insufficient.
It is expected that with the gradual increase in investment in infrastructure projects and the acceleration of urban and rural residential construction, the demand for construction machinery will increase substantially, and new products with famous and high-quality products will be in short supply.
Forklift parts investment casting is one branch of Alloy Steel Precision Casting, which is widely used in forklift markets. Precision casting of forklift parts adopts lost wax casting, also called 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 dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics.
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 24â„ƒÂ±1â„ƒ, which can make the castings much more stable,the internal tissues much more well-proportioned.
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.
Our forklift parts casting has quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The parts can be made completely based on your specifications such as drawing, design, sample etc.
