China Factory Suppliers Custom Screen Printing Squeegee - Essential Ink Transfer Tool for Screen Printing
Definition and Function
Ink Transfer
Transfer the ink onto the substrate through a screen.
Ink Scraping
Scrape off excess ink from the screen.
Contact Maintenance
Maintain contact between the screen and the substrate.
Shape Adaptation
Adapt to substrates of different shapes.
Materials and Characteristics
- Solvent resistance: Able to resist the erosion of various chemical solvents.
- Wear resistance: Long service life, suitable for high-precision printing.
- Hardness range: The hardness is usually between 55-90 Shore A, divided into soft, medium, and hard.
- Elasticity: Good resilience ensures even distribution of ink during the printing process.
Selection and Application of Scraper
- Hardness: Scrapers with high hardness are suitable for high tension wire mesh, while scrapers with low hardness are suitable for low tension wire mesh.
- Ink performance: Select the length, thickness, and hardness of the scraper based on the viscosity, fineness, and hardness of the ink.
- Substrate performance: Hard or uneven substrates are suitable for using softer scrapers.
- Printing requirements: When a large amount of ink needs to be transferred to the substrate, a softer scraper should be used.
- Printing pressure: When the pressure is high, it is not suitable to use a scraper that is too soft.
Product Details
Structure and Size of Scraper
Blade
The sharpness and straightness of the blade directly affect the printing quality.
Effective Height
Usually refers to the part where the scraper extends from the handle, generally not less than 2cm.
Size
Common scraper lengths include 1000mm, 2000mm, 3000mm, etc. The width and thickness can be selected according to specific needs.
Use and Maintenance
The angle, pressure, and speed of the scraper can all affect the printing effect.
Regularly check the sharpness and straightness of the blade, and if necessary, polish or replace it.
Frequently Asked Questions
Q: What is the primary function of a screen printing scraper?
A: The scraper transfers ink onto the substrate through the screen, scrapes off excess ink, maintains uniform contact between the screen and the substrate, and adapts to various substrate shapes during printing.
Q: What material is typically used to make screen printing scrapers?
A: Most screen printing scrapers are made of high-quality polyurethane rubber, which provides excellent chemical solvent resistance, high wear resistance, and reliable elasticity.
Q: How do I choose the correct hardness for my scraper?
A: Harder scrapers (75-90 Shore A) are ideal for high-tension meshes and fine details, whereas softer scrapers (55-65 Shore A) are better suited for low-tension meshes, uneven substrates, or when a heavier ink deposit is required.
Q: What are the standard dimensions available for scrapers?
A: Scrapers are commonly available in lengths of 1000mm, 2000mm, and 3000mm. The width and thickness can be selected and customized based on the specific requirements of your printing machine and setup.
Q: What maintenance does a screen printing scraper require?
A: You should regularly inspect the blade for sharpness and straightness. To maintain optimal printing results, clean the scraper thoroughly after use and polish or replace the blade when it shows signs of wear or nicks.
