Part Marking

Part marking technology

Common parts marking methods are as follows:

Laser marking

Marking is formed by burning the laser beam on the surface of the part, which is suitable for most metal and non-metal materials. This method has the advantages of high marking accuracy, lasting marking and little damage to the surface of the parts.

Chemical corrosion

The use of chemical agents to corrode the surface of the part to form a dented mark. Suitable for metal parts, especially steel products. This method is less costly, but the markup clarity and persistence are relatively poor.

Mechanical embossing

The character mold is pressed into the surface of the part by the embossing machine to form a mark, which is suitable for metal parts with high hardness. This marking method is simple to operate and firm to mark, but it may affect the surface smoothness of the parts.

Electric marker

The use of electric marker on the surface of parts to form marks, suitable for a variety of metal materials. This method is flexible and convenient, but the marking speed is slow, and the operator's skill is required.

Inkjet

By inkjet printer on the surface of the parts to form ink marks, suitable for mass production occasions. This method has high efficiency, but poor marking durability and is easily affected by environmental factors.

Thermal printing

The use of thermal transfer technology to transfer the character pattern to the surface of the part under heating conditions, suitable for non-metallic materials such as plastics. This method is clearly marked, but the heat resistance and wear resistance are poor.

The selection of part marking method needs to consider factors such as part material, marking content, production efficiency and cost.

Part marking advantage

1. Traceability

Quality control: By marking the serial number, batch number and other information of the part, the manufacturer can track the production history of each part, including the raw materials used, manufacturing process, inspection records, etc., to ensure product quality.
Recall management: If a defect is found in a batch of products, the faulty parts can be quickly located and recalled to reduce losses.
After-sales service: In the maintenance or replacement of parts, through the query of the marked information can quickly obtain the relevant information of the part, improve service efficiency.
2. Anti-counterfeiting function

Combat counterfeiting: Unique markings can help distinguish genuine products from counterfeits and protect your brand image.
Consumer Trust: Ensure that consumers are buying certified products and increase their confidence in the brand.
3. Ease of operation

Quick identification: Clear markings allow workers to quickly identify different types of parts on the assembly line, reducing the chance of errors.
Easy maintenance: During routine maintenance or troubleshooting, marking helps technicians accurately locate the parts that need attention.
4. Increase productivity

Automated production: In the automated assembly line, by scanning the marks on the parts can be automated processing, such as sorting, packaging, etc., greatly improving production efficiency.
Inventory management: For the warehouse, the marking of parts helps to achieve information management, easy to track the status of inventory, timely replenishment or adjustment of inventory.
5. Security

Accident prevention: Properly labeled parts prevent misuse or misassembly and reduce the risk of accidents caused by improper use.
Emergency response: In emergency situations, such as fire, earthquake and other natural disasters, can quickly determine the status of equipment through the marks on the parts, guide rescue work.
