Valve stems are typically manufactured using a forging process, where metal is heated and shaped under high pressure to create strong, durable components. The process begins with selecting the appropriate material, such as stainless steel or alloy steel, followed by heating the metal to a plastic state. The heated metal is then forged into the desired shape using specialized dies, ensuring excellent structural integrity. After forging, the parts may undergo machining to achieve precise dimensions and surface finishes, along with heat treatment to enhance strength and wear resistance.

FAQ
1.Which countries do you export to?
U.S.A, Germany, France, Italy, UK, Brazil, Swedish, Japan, Korea, Middle east of Asia, Thailand,
2.How long does it take to receive samples?
A) Pattern:30-45days after order
B) Sample:30days after pattern finishing.
C) The lead time is the general production period and does not include the transportation time.
3.New product development process
Got tooling order and sample order with 50% deposit---Hold a meeting with the relation dept.To ensure the developing schedule---Design mold, fixture and gauge and making them in our house---mold steel buying---Machining---Inspection---Send out the sample with initial inspection report.
4.How long is the manufacturing lead time?
Mass Production:90days after sample approval by yours.The lead time is the general production period including the transportation time.
We could make some special production arrangement effectively if customer has urgent need.
5 How to deal with the quality problem?
A.We perform APQP at an early stage in each project.
B.Our factory must fully understand the quality concerns from customers and implement product & process quality requirements.
C.Our quality professionals who perform patrol inspection in our factories.We perform final inspection before the goods are packed.
D.We have inspectors who perform final audit checks on the packed goods prior to dispatch from China.
6.Can you take responsibility for me?
Of course, I'm happy to help you!But I just take responsibility for my products.Please offer a test report, if it was our fault, absolutely we can make a compensation for you, my friend!
7.What are the payment terms?
Payment terms are negotiable and will improve for long term customers.During the initial stages, we request 50% of tooling fee in advance with the balance payable on acceptance of samples.Production orders can be negotiable.We prefer 50% deposit and the balance by T/T before sails.But sometimes T/T15 days after sails would also acceptable.
8.Which currency can we buy in?
We can deal in USD / Euro currency / RMB
9.How long does it take to ship goods from China by sea?
It takes about 5 weeks to European ports plus 1 week customs clearance, so you can get the container within 6 to 7 weeks.It takes about 2 weeks to east coast and 3 weeks to west coast US ports.All sea goods are shipped from Qingdao Port.
10.How long does it take to ship goods from China by air?
It takes about 7 days to all major destinations.
11.Can we visit the factory to conduct an audit?
Yes, you are welcome to visit our factory.
12.How do we retain client confidentiality?
We are happy to sign Confidentiality Agreements with customers and will honor them.
13.Is there a minimum volume of business required to conduct international purchasing?
There are no minimum volumes, but the prices of the goods, plus the fixed costs of importing makes it more economical to buy in high volumes.All potential customers will be assessed on an individual basis to determine if it appears a viable option for all parties to develop a relationship.
