Reparing project for screw and barrel Details

1. Twist off the screw, according to the actual barrel inner diameter size ,to make the new screw diameter to have a standard gap to the barrel .

2, weared threads of the screw, smaller than original , need to thermal spraying alloy, and then grinding it to right sizes. This method generally has professional spraying plant, repairing cost is reasonable. 

3, Welding the wear-resistant alloy to the weared threads , welding thinckess 1-2mm as per the wearable situation, then grinding screw to the right sizes,  This kind of wear-resistant alloy composed of C, Cr, Vi, Co, B and W material , it increases the screw ability to resist wear and corrosion resistance. The processing fee from professional welding factory is very high, except the customers special requests , this method used rearly.

4, To fix the screw can also be using surface hard chromium plating method, chromium is wear-resisting and corrosion of metals, but the hard chromium layer is easy to fall off.

 

Barrel inner surface hardness is higher than the screw, it's wearable time later than the screw .If the barrel is damaged and can not be used because its inner diameter becomes bigger and weared. Its repairing method is as follows:

1, If the inner diameter of barrel becomes bigger due to the wear, and still have some nitriding layer, we can directly grind the inner of barrel and make it to a new size, then we make a new screw to match this new inner diameter of barrel. 

2. we spray alloy inside of barrel, thickness is between 1-2mm, then grind it to the right size, and make a new screw to match it . 

3, usually the plastification zone of barrel is wearable faster, so we can grind this airea from the length 5-7D, then we make a new special steel alloy  bush to match it . inner diameter of the bush reference to the original screw diameter, keep the normal gap , then processing to match it.
