Quality Inspection to Chinese Foundries, Metal Casting Suppliers,
There are many Chinese foundries,
metal casting suppliers
and manufacturers who are
supplying their iron and steel casting products to overseas, and
more and more buyers are establishing the cooperation with them.
However, it is still a difficult issue to inspect these foundries to
check if they are capable and suitable for producing your products.
Herein, I just talk about this issue based on my years working
experiences in Dandong
Foundry in China.
First way, the best way is visiting your Chinese
The visiting will be the best and most
direct method to inspect the equipments and administration of your
suppliers. However, this way is also the most expensive method since
China is very large, and many Chinese foundries located in the
Second way, asking some questions related with the
quality and technical issues.
Such as some questions about the casting
process, physical properties, chemical components, quality control,
heat treatment, defects, painting, delivery and other aspects. From
their answers, you should be able to learn about their understanding
to the production for your products. Of course, look over the photos
to their products, casting foundries, machining and inspection
equipments will be very basic and necessary.
Third way, searching the news and information from
Google, you could try to search their company name to
check if there is any cheating, defraud, infringement or other bad
news related with them. This is the cheapest way, but sometimes, you
can not find enough information from internet.
Fourth way, making samples and starting the
production from small batches.
If you think the foundry can make the
castings for you, you could pay some prepayment for the patterns to
ask them to make several samples.
However, there are two problems in this way. One is for the
prepayment. Some buyer may want to refuse to pay the prepayment for
the patterns, and want the supplier to make the samples free of
charge. This is unfair to the foundries since they usually need to
pay full payment when they pick up the patterns from the pattern
workshops (most of Chinese foundries can not or do not make the
patterns in-house). Therefore, 30% to 50% prepayment for the tooling
should be reasonable for both buyers and suppliers.
Another problem is for the failed approval to the samples. If the
samples have not passed the approval, then how to solve the
prepayment problem? Personally, I think the foundries should refund
full payment if their samples can not meet the requirements on the
drawings or in the requirements, but the buyers should give more
chances and time to supplier to allow them to remake the samples.
After all, making samples is not an easy thing.
As I know, the most of Chinese foundries have a good reputation and
credit, this is also the reason for many buyers have transferred
their products to China. However, according to many years
experiences in China, there are many difficult issues in quotations,
samples, production and delivery. Both buyers and Chinese foundries
should show their patience and sincerity to their cooperation.
