Three layer sandwich squeegee
Three layer sandwich scraping
With the development of electronic industry, precision screen printing has been developed rapidly, and the requirements of screen printing scraper are also higher and higher. Changzhou prete company introduced sps-msw sandwich screen printing scraper from Japan. He inherited the excellent quality of Japanese scraper, excellent solvent resistance and wear resistance, stable screen printing quality and long printing life, which is suitable for electronic screen printing.
1. Advantages
Sandwich scraping layer hardness up to 95 degrees, in a long time printing
In the process of brushing, it can support the scraping without deformation
Maintain a stable printing angle to ensure uniform film thickness.
2. Size and hardness
2.1 Size
Regular size
a* b* c
9*50*1950
9*40*1950
9*30*1950
2.2 hardness
Different hardness corresponds to different colors
3. Materials
Polyurethane rubber made in Japan
3.1printing surface
One side is wire drawing, the other side is smooth and bright,Looking at the light, the drawing side is selected as the printing surface,Longer life and more stable printing quality

4.Production process
The entire process from receiving an order to shipping
5.Packaging, storage
5.1 packaging
Paper package
10Pcs/Box
5.2 storage
①Store indoors at 40℃or lower, do not store in high temperature and high humidity, direct sunlight and ultraviolet radiation. (Recommended storage conditions: 23℃±2℃, humidity 60% or lower)
②Do not store near heat-generating equipment or dusty places.
③It is forbidden to bend and press, stack it straight, stack no more than 20PCS.
④The scraping rubber is stored at a low temperature for a long time, and can not be used immediately after being moved to the workshop. It should be placed at 25℃for more than 3 hours before use.
5.3 Grinding
Welcome to use the SPS-SG squeegee grinder for better grinding results
①After using the squeegee, please clean the surface ink and rest on the SPS-DR squeegee rack for 12 hours, waiting for the solvent to be released.
②M type traditional squeegee needs to be grinding in the squeegee holder; FGB/AS with support plate squeegee can be removed for grinding.
③Manual grinding machine for grinding
250 mesh grinding wheel: single grinding coarse grinding 0.5mm / fine grinding 0.2mm
400 mesh grinding wheel: single grinding coarse grinding 0.2mm / fine grinding 0.1mm
④The squeegee can be polished with the SPS-Sander to smooth the edge of the knife edge.
note:
SPS squeegee can be grinded many times, the grinding does not melt, the grinding surface is fine, and the edge is smooth
SPS-SG squeegee grinders are available in a variety of custom-made grinding wheels: U-shaped C-angle R-angle (K1-K5)
Plet company is located in Changzhou, China, which is very close to Shanghai. He once sold screen printing inks and served in many electronic industries. He has extensive screen printing experience and realized the importance of squeegee in the screen printing process. In 2013, Plet began to engage in the research and production of support plate squeegee, and established the SPS brand squeegee, which provides stable printing angle and printing pressure for many precision screen printing customers in China.
