Our factory is located in Luoyang, the ancient capital of China, which is a famous historical and cultural city in the world. It is also an important industrial base in China. Many well-known national scientific research institutions have been established here, providing key technical support and services for the development and improvement of the industrial chain. Our company's main business is mechanical parts product design, forging, machining. Auto parts design and production, other mechanical parts design and production, special alloy forging products research and development.The factory has complete production equipment, the hot die forging pressure models are 300T, 400T, 630T, 1000T, 1600T, 2500T, 4000T and other different tonnage forging press, suitable for the production of forging parts weight from 0.05 kg to 50 kg. The factory is equipped with precision machining equipment, with more than 30 sets of CNC lathes, machining centers and other machines, which can ensure the subsequent machining process of batch products. We can produce a variety of material products: carbon steel forgings, alloy steel forgings, copper forgings, aluminum forgings, stainless steel forgings, titanium alloy forgings, tungsten and molybdenum alloy forgings, etc. Our products are mainly used in automobile industry, construction machinery industry, railway locomotive, electric power industry, mining machinery and other industries. Direct and indirect customers of the company are FAW Group, Shaanxi Automobile Group, China Locomotive Group, China First Tow,Heavy Industry, Sinotruk Group and so on.Factory quality control equipment includes flaw detector, hardness tester, spectrometer, metallographic analysis, impact testing machine, tension test, three coordinate measuring instrument, etc., which can effectively control the quality of each product. We have been engaged in the design and production of forging parts for more than 20 years, and have accumulated rich experience in the industry. We undertake to map to sample processing customized OEM services, from three-dimensional modeling design, mold design and production, product forging molding, forging heat treatment, machining and other processes can be completed.Quality Control Each time our customers visit our company for first cooperation, after reviewing our production equipments, another attention is how we would do quality control, which will give them much confidence to place us orders. Usually, we would do inspection for a new steel forging parts in sides of inspections like material, dimensions, mechanical properties and defects inspections.Material Inspection:Ordering material is the first step to make steel forgings, and to ensure the material is what we need, we will require material certificate from material factory.Only material certificate in not enough, after the materials are delivered to our factory,our technical person will also cut a small piece to test the chemical composition by spectrum analyzer, and check if each tested composition is within the range of elements.Besides, after forging, we will also inspect the forging blanks to see if the material composition will changeThe composition, heat treatment process and cold and hot processing process of the alloy directly affect the change of the internal structure and structure of the metal material, so that the mechanical properties of the parts change.Therefore, metallographic microscopy is an important quality control method in the process of forging..Defects Inspection:Although the strength of steel forgings are much better than steel forgings, it may also exsit defects, we can distinguish the defects into surface defects and inner defects.For surface defects such as trimming, cold shut, dents, ects, are mainly tested by 100% visual inspection or MPI(Magnetic particle inspection). But MPI cost is high, which is done when it is requested by our customer, of course, customers will be in charge of the cost.Inner inspection is needed especially when steel forgings are used in safety and strength considerations. Inner inspection of steel forgings include:NDT(Non Destructive Testing): X-ray, UT(ultrasonic testing), ect. This is the most direct way to test the inner defects of products.Section test: Another direct way to see if there is inner defect inside the products is to do section test, and inspect the defects by visual.In this way the products will be broken, and could not be used any longer.As the usage of all these custom steel forgings will be assembled into the machines,so sometimes, it is difficult to inspect some dimensions, to ensure the products can be applied when our customers receive them, we will make a guage/fitting to test if there is any assembling problem.Dimentional Inspection:Dimentional inspection is the most important job for custom steel forgings. Any dimension and tolerance error may cause the product unusable. To guarantee the final assembly, the dimensions and tolerances of steel forgings should be as accurate as possible. So our quality inspector will be in charge of dimentional inspection after products are finished.One way is to testing instruments, such as callipers, depth gage, dial indicator, inside micrometers, height gauge, ect. These will be done by hand operation. For more accurate dimensions, CMM can be used. But only few companies have this instrument for the high price.As the usage of all these custom steel forgings will be assembled into the machines, so sometimes, it is difficult to inspect some dimensions, to ensure the products can be applied when our customers receive them, we will make a guage/fitting to test if there is any assembling problem.Mechanical Properties InspectionFor some special usage or application, there will be some mechanical properties requirements (such as hardness, tensile strength, ect) of the products. According to the needed properties, we will perform heat treatment service after closed die forging. And confirm the expected properties, mechanical testing will be operated to prove the quality of steel forgings. Below are some common inspections about the mechanical properties:Hardness Testing-Is tested when there is a hardness requirement on steel forgings. The hardness will be tested by brinell or rockwell hardness tester.Tensile Testing-A destructive test process that provides ultimate tensile strength, yield strength, elongation and reduction area rate of the products.Packaging & Shipping Packaging1. Rust Prevention: Apply rust inhibitors or surface coatings to prevent oxidation and corrosion.2. Appropriate Packaging Materials: Use materials such as wooden crates, pallets, or plastic packaging to protect the forgings from impact and vibration.3. Padding and Cushioning Materials: Utilize materials like foam plastic or airbags to absorb and disperse impact during transportation.FAQ 1.Which countries do you export to?U.S.A, Germany, France, Italy, UK, Brazil, Swedish, Japan, Korea, Middle east of Asia, Thailand,2.How long does it take to receive samples?A) Pattern:30-45days after orderB) Sample:30days after pattern finishing.C) The lead time is the general production period and does not include the transportation time.3.New product development processGot tooling order and sample order with 50% deposit---Hold a meeting with the relation dept.To ensure the developing schedule---Design mold, fixture and gauge and making them in our house---mold steel buying---Machining---Inspection---Send out the sample with initial inspection report.4.How long is the manufacturing lead time?Mass Production:90days after sample approval by yours.The lead time is the general production period including the transportation time.We could make some special production arrangement effectively if customer has urgent need.5 How to deal with the quality problem?A.We perform APQP at an early stage in each project.B.Our factory must fully understand the quality concerns from customers and implement product & process quality requirements.C.Our quality professionals who perform patrol inspection in our factories.We perform final inspection before the goods are packed.D.We have inspectors who perform final audit checks on the packed goods prior to dispatch from China.6.Can you take responsibility for me?Of course, I'm happy to help you!But I just take responsibility for my products.Please offer a test report, if it was our fault, absolutely we can make a compensation for you, my friend!7.What are the payment terms?Payment terms are negotiable and will improve for long term customers.During the initial stages, we request 50% of tooling fee in advance with the balance payable on acceptance of samples.Production orders can be negotiable.We prefer 50% deposit and the balance by T/T before sails.But sometimes T/T15 days after sails would also acceptable.8.Which currency can we buy in?We can deal in USD / Euro currency / RMB9.How long does it take to ship goods from China by sea?It takes about 5 weeks to European ports plus 1 week customs clearance, so you can get the container within 6 to 7 weeks.It takes about 2 weeks to east coast and 3 weeks to west coast US ports.All sea goods are shipped from Qingdao Port.10.How long does it take to ship goods from China by air?It takes about 7 days to all major destinations.11.Can we visit the factory to conduct an audit?Yes, you are welcome to visit our factory.12.How do we retain client confidentiality?We are happy to sign Confidentiality Agreements with customers and will honor them.13.Is there a minimum volume of business required to conduct international purchasing?There are no minimum volumes, but the prices of the goods, plus the fixed costs of importing makes it more economical to buy in high volumes.All potential customers will be assessed on an individual basis to determine if it appears a viable option for all parties to develop a relationship.
