Typical materials: Aluminum, steel, and brass

Stainless steel and zinc-plated steel are most commonly used to manufacture radiator caps. Steel is a versatile metal and can be molded in any shape. Hence, it is extensively used to make radiator caps for all models of engines.

Metals that can withstand high pressure like steel, zinc, aluminum, and brass are chosen when making radiator caps. These metals can not just withstand high pressure but also endure fluctuating temperatures. Also, metals used to make these components must be rust-proof and corrosion-resistant.

Common MOQ: 500 to 10,000 pcs

The MOQ for common parts is generally higher. MOQs, however, may be negotiated, but importers are advised to be reasonable with their numbers.

制造方法：冲压和加工

A custom design radiator cap is manufactured using stamping, casting, and forging methods. Manufacturers use CNC machining to shape the manufactured components to match your exact specifications. All products are accurate with intricate parts. Manufacturers ensure that products come with smooth surfaces. A 125 micro finish is available on all components, but a higher finish is achievable.

Manufacturing cluster area: Ningbo and Shanghai

Ningbo, on the eastern coast of China, has been an important industrial hub bolstering the Chinese economy. The city is well known for its traditional industries like auto parts, textiles, plastic, mold, and chemical engineering.

宁波是制造家用电器的世界领导者。它拥有超过3,000个家用电器制造商和10,000家生产电器零件的工厂。

Nearly half of all the plastic machines in the world are produced in this city. Hence, Ningbo has been aptly nicknamed the ‘Home of Plastic Machine.’

Shanghai is the commercial capital of mainland China. It is a major industrial hub and accounts for nearly 12.5% of the total revenue of China.

Agriculture and the service industry are major drivers of Shanghai’s economy. Manufacturing is another key industry in Shanghai. Other important industries are electronic information products, automobiles, petrochemicals, fine steel, equipment, and bio-medicine.
