FAQ

1. Can I get free samples?

A: Yes, we can provide you the free sample, but you need to bear their own delivery costs.

2. Can I request to change the form of packaging and transportation?

A: Yes , We can change the form of the packaging and transportation according to your request, but you have to bear their own costs incurred during this period and the spreads.

3.Can I request to advance the shipment?

A: It should be depends on whether there is sufficient inventory in our warehouse.

4.Can I have my own Logo on the product?

Q: Why does the precision casting factory not usually make iron castings?: The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.

Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished: 1, gray cast iron: General graphite annealing, to be heat treatment annealing, surface hardening etc.; ductile iron can be various: annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical heat treatment.2. Pouring liquid metal into the casting cavity which adapts to the shape of parts. After cooling and solidification, the casting method is called casting. Castings obtained by casting are called castings. Casting structure design: ensure the working performance and mechanical performance requirements, consider the technical requirements and performance of alloy casting casting casting structure, casting structure design is reasonable or not, the casting quality, productivity and cost has a great influence.3. Heat treatment is a metal hot working process in which the material is in solid state by means of heating, heat preservation and cooling to obtain desired microstructure and properties

Q: Domestic large steel castings factory which is better, recommend!: Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.

Q: How do casting parts remove stress?: Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment

Q: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?: Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably casting.

Q: Is the cast steel a casting part?: Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic casting.

Q: What is the difference between casting and stamping parts?: Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.

Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?: There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.

Q: When there is no flaw detection for large casting parts, is there any crack inside?: Cracks are considered serious levels of defects and should be repaired
