How to guarantee the quality of large carbon steel or alloy steel casting
We have our quality control procedure and advantages to guarantee the quality of castings as follows:
Most of the pattern will be made by our experienced technicians.Sometimes it will also be sent to our subcontractor.All of the patterns should meet our quality control requirement.After the pattern is finished,the quality control department will check the dimension of the pattern carefully.A right pattern can save production cost and time.
sand mold making and riser
Most of our sand mold makers can be thought an artist in sand mold making with more than 10 years experience.
For the important R corner,we will use chrome ore to avoid sand adhesion.
The engineers will inspect the production process especially for some new or important large carbon or alloy steel castings.
The sand cores will be painted and roasted to avoid sand adhesion and pores on the surface.
The sand mold will be roasted before pouring by drying machine.
We use big risers to make the casting quality better.
We have a electronic total station imported from Japan to help us to inspect the dimension.
