Engraved Metal Label | WEIHUA

Definition of engraving signs

1. Engraved metal labels, which can be diamond cut signs, laser engraved signs, or etch signs, which is a combination of drilling and milling.

2. Engraving signs generally process metal nameplates such as stainless steel plates, aluminum plates, and copper plates;

Engraved signs are generally suitable for industrial machinery equipment signs, electrical appliances and other signs (such as washing machine signs, microwave oven signs, oven signs, air conditioner signs, refrigerator signs, etc.), electronic products and other signs (such as mobile phone signs, headset signs, audio signs, etc.) Etc.), furniture signs, etc.

1. Laser engraving (laser engraving)

Based on numerical control technology, laser is the processing medium. The metal material melts and vaporizes physically under the laser irradiation instantaneously, so as to achieve the purpose of processing. With laser engraving machine using laser engraving technology, vectorized graphics can be easily "printed" onto the processed substrate.

The advantages of this technology are:

①Precision: The thinnest line width of the material surface can reach 0.015mm, and it is non-contact processing, which will not cause product deformation;

②High efficiency: You can get the physical products of new products in the shortest time, and you only need to change the vector file for multiple varieties and small batches;

③Special processing: to meet special processing requirements, inner surface or inclined surface can be processed;

④Environmental protection and energy saving: no pollution, no harmful substances, higher than export environmental protection requirements.

2. Engraved signs: We often see some metal nameplates, the products or company on them are marked with slanted or straight thread-like stripes, which are generally diamond cutting signs

3. Etched signs are also called corroded metal signs. Mainly check embossed metal signs or indented metal signs made by three-step processing of masking and etching post-processing. Surface treatment of general metal corrosion signs: mechanical polishing: use a 2.2-4 kilowatt polishing machine to mechanically polish the wool, use a cloth wheel with a 300-350 motor speed generally 2000-3000 rpm; alkali treatment; use mechanical or manual The wire drawing method involves wire drawing on the surface of the metal plate to achieve the regeneration effect of the metal surface, which is brushing.

At the same time, in addition to engraving signs, there are other common sign processing methods:

1. Polishing: Overcoming defects, deburring and brightening the surface.

2. Sandblasting: The purpose of sandblasting is to overcome and conceal some defects of aluminum alloy in the machining process and meet some special requirements of customers for product appearance. There are glass sand, tungsten sand, etc., showing different feelings. Similar to the rough texture of ground glass, fine sand molds can also show high-end products.

3. Car pattern: It is a processing method for reprocessing after the mold is formed, and the pattern is processed by a lathe. Adults show very regular texture features.

4. Rubbing: There is called drawing. The performance is similar to the car pattern, both of which form a smooth continuous pattern on the surface. The difference is that the car pattern is expressed as a ring pattern and the rubbing pattern is expressed as a straight line.

5. Oxidation (coloring): The purpose of oxidation is divided into two aspects: enhancing physical properties; it can achieve the purpose of coloring.
