Typical materials: zinc alloy, aluminum, steel, and brass

Steel is most commonly used for latches due to its tensile and shear strength. Stainless steel also provides superior corrosion resistance and it is rust-proof.

Zinc is a material of choice for corrosion resistance. It is versatile and can be very easily shaped. Zinc is also a sustainable choice as it is a highly recyclable metal.

Aluminum products can withstand harmful UV rays and are extremely weather-proof. They are also corrosion-resistant and offer optimal performance for a long time. Aluminum is ideal for various manufacturing methods and can be fabricated for a variety of uses.

Brass has excellent plating, joining, finishing, and polishing characteristics. It can be easily machined to be formed into different shapes and styles. Latches made of brass are durable and have a long service life. It is also corrosion-resistant and rust-proof.

Common MOQ: 100 to 10,000 pcs

For common or standardized parts, the minimum order quantity is generally higher. Buyers are advised to be reasonable with their numbers even though MOQs are negotiable.

Manufacturing methods: Stamping, machining, casting, and forging

Our Chinese manufacturers ensure that all products are made exactly as per your specifications. The products are precise with intricate parts. Manufacturing methods like stamping, casting, and forging are used to manufacture the components. These products are then machined according to your requirements. They are polished to have a smooth surface. All components come with a 125 micro finish, but a higher finish is achievable.

Manufacturing cluster area: Ningbo and Shanghai

Ningbo is an important industrial city in China. Textiles, garment, auto parts, home electric appliances, plastic machinery, and high-end mold are some of the major industries in the city.

The city houses over 3,000 home electric appliance manufacturers and nearly 10,000 factories that produce electrical appliance parts and accessories. The annual turnover of the home electric appliance industry in Ningbo accounts for 30% of the entire industry in China.

Shanghai is the hub of international trade and finance in China. It is home to the Shanghai Stock Exchange and the Shanghai free-trade zone, the first of its kind in China. It is well known for its trade, finance, and shipping industries..

Application: Aesthetics and architecture

Latches are a type of mechanical fastener that joins two objects or surfaces, at the same time allowing their regular separation. They are used for a range of functions, including door latching, gate latching, cabinet latching, and paddle latching. Latches are required to be heavy-duty and hence are made from steel, aluminum, brass, and zinc to make them durable and long-lasting.

Latches are extensively used in a large number of industries, including furniture, transportation, construction, and security.

Common issues: Surface finish and dimension control

Our Chinese manufacturers ensure that products go through mandatory quality checks to meet the quality standards stipulated in your manufacturing agreement. All components are manufactured exactly as per your specifications, including a smooth finish.

Quality Control

Finished products are inspected against a known good product to make sure they meet the quality standards. They also undergo CMM inspection to test the accuracy of the manufactured components.
