Use of rust remover in precision sheet metal processing

    1The working surface after precision sheet metal processing (chǔ lǐ) will be attached with a passivation film, with a thickness of about 1 micron. It is a reaction product of a special inorganic substance and steel in the rust remover, which can protect the steel Role. Sheet metal processing in Suzhou With the increasing application of sheet metal, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must be proficient in the design of sheet metal parts, so that the designed sheet metal It not only meets the requirements of product functions and appearance, but also makes the manufacturing of stamping dies simple and low cost.

2 The processed workpieces (chǔ l 的) should be arranged separately and neatly to facilitate drying. Suzhou chassis processing sheet metal chassis processing materials will be sent to CNC punch / cutting machine for punching / cutting process. The bending process mainly considers tool selection, bending sequence, bending compensation, bending interference and so on. According to the situation of the sheet metal chassis and cabinet products, welding, sanding, painting, assembly, packaging and other processes are performed. After derusting, please air dry or blow dry, and do not wash with water. Paint or apply anti-rust oil as soon as possible after work is dry. If you want to achieve the best results, you can choose a series of high-quality rust inhibitors (oil-soluble, water-soluble, hard film, dehydration) according to different working conditions.

3 After using the rust remover for a period of time, the surface foam and sediment should be cleaned in time and a concentration test analysis should be performed (Analyse) in order to replenish the new rust remover in time to ensure the rust removal effect (see the concentration control method for details ).

4 Short-term contact with this product (Product) is not harmful to the skin, if long-term contact should take appropriate labor protection measures (wear glasses, rubber gloves, wear protective clothing, rubber shoes) to ensure precision sheet metal processing operations Control personnel safety. Suzhou sheet metal processing technology, sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, riveting, splicing, Molding (such as car body). If you accidentally spill liquid into your eyes, immediately rinse with water or consult a doctor. Do not swallow rust remover.
