About 3 d flexible welding platform, casting and steel which good?

   With three dimensional flexible welding platform is blossoming, utilization rate increased year by year, according to the customer's feedback and long time experience, three dimensional flexible welding platform expert analysis of 3 d for you cast iron platform and three-dimensional steel platform differences.

First of all, let's explain it for you, the three dimensional platform steel (Q345).

Q345 material assembling platform is to use steel plate welding, and then processing. Advantages, compared with castings, making simple, together with steel plate, welding can be processing, production of relatively few hours. Disadvantages: easy to deformation in use process, welding slag is not easy to clean.

And cast iron material platform is to avoid the above shortcomings, the material of cast iron is generally grey iron (HT300), another is nodular cast iron (QT500).

Because cast iron is a integrated platform, so it is not easy to deformation in the process of using, and not easy to welding slag.

The characteristics of grey iron (HT300) :

1. Good abrasion resistance and vibration free.

Due to the kind of graphite cast iron is good for soothing and storage, so good abrasion resistance. Also, because of the existence of graphite of gray iron damping resistance than steel.

2. Process performance is good.

Because the grey cast iron carbon content is high, close to the eutectic composition, so the melting point is lower, good liquidity, small shrinkage rate, thus suitable for casting structure or complex thin wall castings. In addition, because the graphite again when machining is easy to form the chip breaker, so grey cast iron can be cutting machining is superior to the steel.

3, the use of the advantages of resin sand casting:

Good resin sand mould rigidity and high strength of casting sand mold early, this is a conditional use the graphitization expansion of the solidification process of cast iron, effectively eliminate the shrinkage cavity, shrinkage defects, realization of gray cast iron, ductile iron pieces of riser, less without riser casting.

In foundry production using polystyrene foam plastic, application of furan resin sand moulding process and the model. When liquid metal poured into the mold, foam plastic shape and under the action of high temperature metal liquid rapidly gasification, combustion and disappear, replaced the original liquid metal foam occupied position, cooling solidification into type and shape of the same shape casting.

Relatively speaking, epc for single piece or small batch production of castings, has greater advantages than the traditional sand mould, it not only saves expensive wood type, is easy to operate, and shorten the production cycle, improve the production efficiency, has high dimensional precision, small machining allowance, good surface quality and other advantages. Therefore, when concerning the special requirements of customers, we will develop a meets the needs of customers. Aging fast, short delivery time.
