Squeegee Hardness Tester GS-719N       Made by TECLOCK CORPORATION in Japan


DUROMETER, RUBBER and PL ASTIC HARDNESS TESTER isproduced from a thought that there might be a manner to express anambiguous sense of human feelings about the hardness, e.g. "slightlysoft", by a numeral value which can be compared by some physicalmanner, and that it might be possible with an elastic material which canbe distorted by a human force.

The basic concept of this idea is following as shown in the below figure.When the Indentor of specific shape gives a distortion onto the surfaceof a specimen with the pressure produced by the specific spring load,the specimen produces a resilient force against the pressure load.

The "hardness" means the depressed  Indentoramount of Indentor at the time when the resilient force becomes equal to the pressure load. Since so called the Indentor of specific shape  and the specific load are the values given by human experience or experimental sense, the value consequently got is a "relative physical amount" with no unit.  

Screen printing requires the use of different hardness scrapers to match different printing processes.Different scraping hardness, the support of screen printing is not the same.

Company Profile

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.

Customer Praise

A. Photovoltaic Company Production Manager India:We are a company that prints battery sheet, SPS-AS carbon fiber squeegee printing Battery sheet grid is relatively small, printing life is long, each average reaches 50,000 times.

B. PCB circuit board company Technical staff China: Before we cooperate with SPS Squeegee, when we do the through hole printing process, the silver paste is not easy to penetrate the hole, and the scrap rate is very high. After talking with SPS technology, they recommended the new squeegee, which helped us solve the problem of low yield rate of through-hole printing. Thank you very much.

C. Membrane switch company quality management personnel Vietnam: SPS recommended R angle scraper printing transparent color effect is excellent, no squeegee marks, the surface looks very smooth, we will also apply R angle squeegee  to the window printing liquid printing process, hope to reduce the rate of defective rate.

 D. Technical Director of Chip Manufacturing Company Taiwan: We print insulating ink on special film, and 160 products are printed on A4 size film. This has high consistency on film thickness. The film thickness made by traditional squeegee,the film thickness in the middle and the film thickness of the edge product differ by 3 microns, and the carbon fiber squeegee using SPS solves this problem, and the film thickness of the entire printing surface is controlled by 13±1 μm.
