Screen printing screen made of

     In addition to the stability of the printing machine, printing when the screen is good or bad, directly related to the printing effect, so it is important to screen printing halftone

     A, screen production process

     Photosensitive slurry material, determine what we want to use the technology, but the general program is unchanged: net yarn. Net frame size, Seine, washing net, the sensitive materials, exposure, development and drying.

   Production of screen printing halftone to note:

      1 white gauze, silk-screen printing machine, how to choose
Currently on the market breed: silk screen, nylon silk screen mesh, polyester silk mesh, wire mesh, etc., including the most commonly used nylon net yarn

     Nylon suzhou silk gauze advantages: soft, high elasticity, friction resistance, acid and alkali resistance, long life, high cost performance, through the ink

     Disadvantages: lift is too large, ink printing machine is easy to cause ghosting, and not resistant to high temperature

      Screen mesh number 30 mesh/cm, 40 mesh/cm, 60 mesh, 80 mesh, 120 mesh/cm/cm/cm, and 160 mesh 140 mesh/cm/cm, choose according to demand

     2, screen printing machine net frame specifications of the Shanghai

     A wooden frame, aluminum frame, iron frame, copper, stainless steel box, box, plastic box commonly used a wooden frame, aluminum frame, iron frame, etc.

      On the market the most commonly used aluminum frame: advantage is that small deformation, light volume, no rust, if the tension is not enough, more coarse screen printing frame of the internal increase strength.

Second, the stretched gauze

     Suzhou silk screen factory house which good?Plate, the method of net can be divided into manual, mechanical harmonious lift net three, such as silk screen processing plant for accuracy is not high, generally USES the first two ways;If the demand is higher, can use the last kind of pneumatic net machine, pneumatic net machine suitable for network version of high precision control.Characterized by tensile mean, convenient use, to the different need net tension, especially suitable for control of high precision printing a few color screen printing machine matching color screen printing.

Three, flush the screen

      Ink thinner, washing net water, detergent washing.Also can use the washing powder, detergent and other cleaning.The choice of appropriate a little coarse cloth, scrub gently, so that the nylon line can appropriate wear.
Four, coating

     1, selecting photosensitive slurry

Photosensitive slurry have pad printing photosensitive slurry and silk screen printing photosensitive slurry, choose the screen printing

      2, coated

     The required items: photosensitive glue, sizing machine, scraper, transparent lamp.

,   and then will nets drying, the process for the first time.(note: line, the character screen printing need a secondary coating)

, if you want thicker, it will need to loop on both sides of photosensitive slurry

    Loop back and forth, with hot winds or oven roasted, guarantee completely dry.

     Note: production network version must be patience, just like treat a girlfriend.Practice, work to nature, three fat making nuclear weapons out of north Korea Kim determination, all can be successful, high precision screen printing factory needs a lot of aspects of personnel, this work more than 20 k is also very normal, especially printing mobile phone cover, such as foxconn, burns, blue, etc, the demand is very big, technology well, instant prick silk counter attack.

    3, drying

     Nantong silk screen after the photosensitive glue coating machine, first let stand 1 to 2 minutes, and then put the screen in around 40 ℃ baking in the oven, drying out in the dark frame.

     Note: suzhou silk screen printing what price?Must be dry, otherwise will affect the network version of robustness.

Five, exposure

Will be posted on the silk screen printing surface film, then put in a vacuum.

Sixth, developing

Remove the cooling, and then rinse until the image.

Seven, nuclear

     To high power magnifier, under a microscope to see again, see if there is any breakage and not rinse, such as breakage is discarded.If not wash out, then rework.
We make mobile phone touch screen, probably did more than 100 blocks to succeed in doing.We do auto parts, inner decoration and the audi car dashboard, make steel plate proofing for 20 to success for many times, take out your patience, you can do it!

Eight. Silk screen printing machine

      Screen printing machine, also called screen printing machine, suzhou, Shanghai this piece, the production of screen printing and pad printing machine in kunshan factory is 2-3, nicky oulette is
     One screen printers have a manual screen printing machine, semi-automatic screen printing machine, automatic screen printing machine, rotary screen printing machine, automatic screen printing machine, is customized according to customer demand.Our equipment adopt servo motor, simple, convenient, fast.Installed high-quality screen, printing work wonders.
