Fixture
     
 
     
Different products require different fixture which orientation support and overprint function in the process of pad printing, screen printing or hot stamping.

 
1.For Regular Products
 
      Cylinder, cuboids objects need the fixture that is produced by mechnical process.This fixture can achieve the accurate position tolerance.
 
          2.For IrregularProducts
 
          Most of mold-plastics products have complex surface. It is easy to make fixture by no-saturation polyester resin. When adding hardener and activator to the resin, infusibility solid will be build for chemicals reaction. Put the product into resin before it become solid, one fixture finish.
 
           3.For Standard Cylinder Products
 
           Cylinder products are usually used in screen printing, hot stamping and heat transferring. The fixture will keep the product runming around the axis freely. When screen plate, stamping plate or silicon roller press down and contact with products, the fixture brings product moving around.
 
          4.  Regard anchor point
 
         It is important to look for comm onness anchor point on product. High-quality fixture will ensure high quality printing .

     In order to achieve printing on special-shaped substrates, they must be fixed according to certain requirements, so that the relative positions of the printing surface and the embossing parts meet the requirements of the printing process. The device that keeps the printed surface of the printed product in line with the requirements of the printing process is called a fixture. In the special printing industry, the shape of the substrate can be said to vary greatly, and the position of the printing surface on the substrate is also different. Whether it can be printed accurately according to the requirements of the model, the fixture plays a key role. For some irregular plastics, electronic products and other substrates, it is costly and troublesome to make positioning devices by machining; while casting is simple, fast and easy to position; therefore, it is very useful in the special printing industry. widely.

Fixture production requirements

  •    When subjected to a certain pressure, no displacement or deformation occurs.

    Deformation of the workpiece can cause deformation of the print.

  •   Ensure that the tangent plane of the highest point on the printing surface of the substrate

   is as parallel as possible to the printing plate surface. The printed material depends on the printing pressure to obtain the imprint. When designing the machine, the pad printing head, scraper, and hot stamping head are designed to be perpendicular to the plane of the printing plate to obtain the maximum printing pressure. Therefore, when making the positioning device, try to ensure that it is consistent with The printing plate surface is parallel to keep the printing pressure between the stamping parts and the substrate in an optimal state.
Can be installed on the table of the printing press. Whether it is a pad printing machine, a screen printing machine, or a hot stamping machine, the workbench is designed with a wire hole for installing a positioning device, and the size of the positioning hole of the positioning device must meet the requirements.

  • The workpiece is easy to load and unload.

To achieve mass production, uninterrupted loading and unloading is very important. In the case of ensuring accurate positioning, the positioning method of the workpiece on the positioning device should be as simple as possible.

  • Products that require color registration require accurate positioning.

Accurate color registration is the basic requirement of printed matter. For the positioning device, the workpiece cannot move horizontally or vertically during the printing process. For the circular surface, the rotation in the circumferential direction must be prevented.
