Production Process:

Raw materials:  Many types of steel plates are available :Q345,NM400,HARDOX,etc The material will be quality-inspected when they are delivered to the workshop.


Cutting:  We have two kinds of cutting machine:numerical control cutting machine and numerical plasma control cutting machine.The former is used to cut steel plates with a thickness of more than 20mm, and the latter is used to cut steel plates with a thickness of less than 20mm.

They cut the entire steel plates into each part of bucket according to drawings,then the parts will be polished and sent to machining area.


Machining Area:

--Drilling & Boring 

-Mainly drill the holes in bushing and side cutting edge.

-Accurate inner diameter of bushing to make sure the pins match the bushing perfectly.



-Processing flange plate (CAT and Komatsu excavator over 20 ton bucket will use flange plate).



-Make groove at steel plate to increase the welding area and make sure more solid welding.


Welding advantages:

Welding Area-The most remarkable of our advantage

-Bonovo uses carbon dioxide gas shielded welding machine and flux-cored wire ,which is adapted to any position in space . Multi-pass welding and multi-layer welding are all our feature.

-Adapter and blade edge are both through preheated before welding. The temperature is controlled reasonably between 120-150℃

-The welding voltage is maintained at 270-290 volts , and the current is maintained at 28-30 amps to ensure the stability of welding process

-Experienced welders are technically skilled with double hands , which makes the weld seam achieve graceful fish-scale shape


Shot blasting advantages:

1.Remove the surface oxide layer of the product

2.Releasing the welding hard force generated during welding

3.Increase the paint's adhesion and make the paint more firmly absorbed on the steel plate.

From raw materials to finished products, the whole process is under strict quality inspection included  flaw detection,weld inspection,structure size inspection,surface inspection,painting inspection,assembly inspection,package inspection keep our quality standard,
