Every May to July is the busiest season for industrial packaging companies, and 2010 is no exception. As market demand gradually returns to the level before the economic downturn, customer demand has also increased, but the capacity of packaging manufacturers has been affected by rising costs of steel and plastic raw materials and energy, and has not been significantly improved. In addition, people’s concern for environmental issues and the urgent need for personalized retail packaging are constantly testing the wisdom and determination of packaging suppliers.
As a whole, the recycling and recycling system in the industrial packaging sector is relatively complete, and most plastic and steel containers can be recycled. The strict legal provisions also ensure the safety and high standards of these materials to the greatest extent. . Of course, some laws and regulations just encourage companies to recycle their packaging, and they neglect to reuse them, causing many high-quality packaging to be split and completely unable to function again.
Throughout Europe, it is generally believed that the benefits of industrial packaging have not been fully understood by the market, and its characteristics in terms of safety and environmental protection are also different from retail packaging. First of all, we should analyze the life cycle of steel, plastic and fiberboard containers to find the characteristics of each material - steel and plastic are strong, can be reused and recycled; fiberboard packaging is lighter in quality, natural environmental protection, Easy to recycle.
Recently, the ISO Packaging Environmental Protection Committee and representatives of 15 countries gathered in Beijing to discuss the existing European, Asian and North American requirements. The topics discussed included resource reduction, reuse, recycling, energy recovery, and chemical recycling. New standards and organic recycling (composting and biodegradation) are the latest advances in many fields.
In addition, the safe use and transportation of industrial plastic packaging is also a common concern among people in the industry, especially how to ensure the safety of packaged goods in international transportation.
Petroleum parts investment casting is one branch of Alloy Steel Precision Casting, which is widely used in petroleum markets. Casting for petroleum 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 24℃±1℃, 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 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 petroleum parts investment cast has quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The investment casting of petroleum parts can be made completely based on your specifications such as drawing, design, sample etc.
