Mechanical signs are very easy to see in our daily life. They are mainly applied to mechanical equipment to test the specific parameters and names of our equipment. They are mainly products produced through different manufacturing processes. The manufacturing methods of mechanical signs are as follows:

Step 1:

Mechanical signs are signs on machinery. It is mainly to check the embossed or concave signs made by three steps of mask and post etching treatment, and then use the way of photosensitive plate drying to dissolve different colors into the adhesive film, so that they can be displayed on the metal plate by developing, so as to achieve the purpose of explanation. Dalian casting

Step 2:

Then use resin ink to screen print on the pretreated plate surface, and then protect the light and cover the film. A special panel is generated by the surface treatment process of the metal plate, and then print the color pictures you have designed on the conversion paper by inkjet printing, and reverse them to the metal plate by heating.

When the crane leaves the factory, a metal nameplate shall be installed at the obvious part. The nameplate shall at least include the following contents:

（1） Product name and model;

（2） Equipment code:

（3） Product number;

（4） Manufacturing license number;

（5） Rated lifting capacity;

（6） Working speed (lifting speed, crane running speed, trolley running speed);

（7） Span;

（8） Lifting height;

（9） Operating level of the whole machine;

（10） Name of manufacturer.
