(centrifugal casting sleeves made in Taiwan)

Centrifugal casting sleeves ( shaft sleeves / wear sleeves) produced by LAWAI INDUSTRIAL CORPORATION

LAWAI INDUSTRIAL CORPORATION manufactures centrifugal casting products in Taiwan and centrifugal casting sleeves ( shaft sleeves / wear sleeves) are our top products.  Why lots of customers choose stainless sleel sleeves manufactured by centrifugal casting?  The main reason is that the products manufactured by centrifugal casting technique perform excellent mechanical and physical properties, and maintain good performance in the harsh environments.  Therefore, centrifugal casting products still dominate a place in the casting industry.

Our centrifugal casting sleeves ( shaft sleeves / wear sleeves) are applied in pump, chemical and marine industries mainly.  The materials we produced a lot are stainless steel 304, 316, 316l, 17-4PH and duplex 2205.  Although these alloys are common, the quality of products made by centrifugal casting technique is much better than traditional casting. 

There are several methods to produce stainless steel sleeves ( shaft sleeves / wear slevves).  However, centrifugal casting is the one you must know.

• Customization is one of the advantages of centrifugal casting.  Most shaft sleeves / wear sleeves are special and used in the severe environment. The dimensions are quite different from spec. products.  We use the suitable molds to produce the shaft sleeves / wear sleeves with the exact dimensions for customers to do the finish machining. 
• The grain structure of centrifugal casting is fine.   The almost zero pores of centrifugally cast sleeves that are easy to be finish machined. 
  
• Flexibility is quite good feature of centrifugal casting.  The lower order quantity is feasible.
• The comprehensive materials could be cast  is quite good for customers to select one for the application. Centrifugal casting is able to produce all alloys in theory. 

After we talk about the advantages of centrifugal casting, we would like to introduce this technique briefly to you whom want to know more in depth.

What is centrifugal casting?

Centrifugal casting is an art that the molten metal is poured into the mold, the mold is rotated by the high speed and the liquid metal would solidify uniformly. The unique part of centrifugal casting is that the centrifugal force is generated when the mold is rotated by the high speed and the solidification in the same direction.  And these processes make centrifugal castings have two major advantages.  One is centrifugal casting is very pure and the other is centrifugal casting is with high strength. 

How centrifugal casting works?

In the beginning, we should select the appropriate mold and preheat the mold.  In the meantime, we also need to melt the alloy we choose.  Then, pouring the liquid metal into the mold that is rotated.  When the mold is rortated by the high speed and the centrifugal force would make the impurities flow into the inner diameter and the metal with higher density would be driven to the outer diameter.  When achieving the ideal thickness, we would not pour the liquid metal into the mold anymore.  Then, the mold would be processed into cooling status.  After the cooling , the tube would be pulled out and we do the machining on the inner diamter to remove the impurities. 

Once the casting is finished, the tube would be delivered to do the heat-treatment or finish machining. 

There are two types of centrifugal casting

One is vertical centrifugal casting and the other is horizontal centrifugal casting. 

1.     Vertical centrifugal casting

Vertical centrifugal casting machine is used to produce tubes with larger outer diameters and shorter lengths.  One of the advantages of vertical centrifugal casting is that it saves space for foundry and another pro is it is easy to place the complicated inserts into the mold.  It is good to produce flanges and other shorter cylindrical components.  

2.     Horizontal centrifugal casting

Horizontal centrifugal casting machine is used to produce longer tubes.  The production process is the same as vertical centrifugal casting.

The advantage of horizontal centrifugal casting is the length could be long, so it is very suitable for manufacturing seamless steel tubes.  However, the con is that the space of the foundry should be large.  And it is more difficult to repair the molds because those are much longer than the ones for vertical centrifugal casting machines. 

The applications of our shaft sleeves / wear sleeves 

Centrifugal castings are with the excellent mechanical properties and very fine structure.  Therefore, they are usually applied in the harsh environment ( corrosion or wear resistance is necessary)

Our shaft sleeves and wear sleeves were used in pump, marine and mechanical industries a lot.  Stainless steel sleeves produced by centrifugal casting are highly durable.  Thus, they are the excellent compoents to protect the shafts.
