Machining Process


Die casting process

In the past 10 years, the company has been expanding the production scale of the die-casting workshop. At present, there are 18 dc88 hot chamber die-casting machines, 9 dc160 hot chamber die-casting machines, 1 dc200 hot chamber die-casting machine and 1 dc200 hot chamber die-casting machine manufactured by Lijin Machinery Factory Co., Ltd. It has also established two automatic soup matching production lines to improve the automation level and gold level of die-casting production It belongs to the quality of molten liquid. After many years of production experience, we have summed up a set of advanced and strict die-casting production process, the product quality is second to none, and the annual production of zinc alloy products is more than 6000 tons.

Stamping process

Since its establishment, the stamping workshop of the company has continuously expanded its production scale, introduced advanced production equipment, and continuously improved and transformed its processing technology. In order to improve production efficiency and optimize production structure, the company has added more than 700 automatic stamping workshops, including a series of processes such as the largest 120t punch, supporting cold stamping, bulging, punching and shearing, stretching, and binding. In addition, the expansion equipment, with the completion of the product molding requirements.

The stamping workshop is equipped with a mold making center, which is responsible for the development and production of all the stamping dies needed for production, including single punch and automatic continuous punch.

The common materials for production are cold plate, copper sheet, stainless steel and heterosexual material, with thickness ranging from 0.02mm to 4mm; the cold plate material can be used for stamping processing about 600 tons, copper material 300 tons, stainless steel 60 tons, with monthly production of about 120 million punches.



Spray processing

Since 2001, the company has established five electrostatic powder spraying production lines, including three transparent powder spraying lines and two colored powder spraying lines. According to the product requirements, with bright or matte, indoor or outdoor products, use mixed, polyester, acrylic, pure epoxy and other systems of powder coating, and easy porcelain dragon and other special coatings.

In order to ensure the quality of products, the surface treatment testing laboratory is equipped with coating testing equipment, and regular sampling testing is carried out in batches, such as film thickness, adhesion testing, salt spray, humidity testing, etc.

Select quality assurance paint supply partners, such as Akzo Nobel Changcheng paint, Rohm Haas, PPG, tiger and other companies; use Swiss Jinma, Korean KCI and other spraying machinery and equipment.

Electroplating process    

Zhongshan Huafeng electroplating Co., Ltd., founded in February 2000, is a subsidiary of Zhongshan Huafeng lock making Co., Ltd. The company passed the environmental management system of ISO14001:2004 certified by NQA in 2011, and is an advanced unit of cleaner production in Guangdong Province.
