Cold Heading Parts Manufacturer In China
Ningbo Teng Qi Fasteners Co., Ltd is a leading cold heading parts manufacturer in China. Cold heading is a manufacturing process used to produce parts, often fasteners or components, from metal wire or rod stock without the need for extensive machining. The process is called “cold heading” because it forms the parts at room temperature without heating the material. Parts produced using cold heading are often referred to as “cold headed parts.”
Cold heading is a cost-effective manufacturing method for producing large quantities of precision parts, especially when the parts have simple and symmetrical shapes. Cold headed parts are commonly used in various industries, including automotive, construction, electronics, and aerospace, for their strength, reliability, and efficiency in mass production.

FAQ about cold heading:
1.What quality control measures are in place for cold heading parts?
Quality control measures often include dimensional checks, material testing, and inspections to ensure that parts meet specified tolerances and standards.
2.Can cold heading be used for small or large production runs?
Our daily production capacity of A193 b7 stud bolt is about 20 tons, but due to the arrangement of materials, heat treatment, surface treatment, order scheduling takes time. The average delivery time of bolts for a container is 30-40 days.
3.What are the key specifications to consider for cold heading parts?
Key specifications include material type, material diameter, part diameter, length, head style (if applicable), thread type and pitch (for threaded parts), tolerances, surface finish, hardness, quantity, and any special features.
3.What countries do you export your a193 b7 stud bolt to? Whether mechanical properties can be guaranteed.
We have stable customers in the United States, Germany, Russia, Poland, Spain, Brazil, Argentina, Vietnam, Canada, Australia, UAE, Saudi Arabia and other countries for more than 10 years. Our bolts are guaranteed to meet ASTM A193 standard mechanical performance requirements.
4.Can you provide samples of A193 b7 stud bolt?
Yes, we have some samples in regular sizes. Samples can be provided free of charge. But the customer needs to bear the freight.
5. Do you have a minimum order quantity requirement?
Yes, the MOQ we usually produce is about one ton.
