How to choose screen printing machine
Usually in domestic printing machinery factory manufacturing printing machine general points of two categories: the oblique arm (hinge) type vertical horizontal type printing machine, silk-screen printing machine and subdivision and pneumatic type and electric type.
1. Oblique arm type printing machine features: it is through the rotation of the crankshaft drives the hinge body lift, its frame stress point inconsistent (like a beam). It is also the defects of screen printing machine (this is a structural defects, none the manufacturing precision of the manufacturer), want to know, to print design of high quality silk screen printing screen scraping force must be uniform pressure, and oblique arm type pressure before and after the printing machine is easy to appear inconsistent.
2. The vertical horizontal screen printing machine to make up for the shortcomings, it USES the linear guide horizontal movement, as each point of the pressure it printed pattern for network printing, ink layer for uniform electronic product screen printing and multi-color overprint, is the best choice, it also has a characteristic is straightforward operation, installation screen simply and quickly, convenient adjustment pressure stability, the new worker training easy to use.
So inclined arm type printing machine are good for nothing, also not be, its relative price is low, take easy, it is the short direction of printing, relative efficiency fast xiao xu, for some low requirements for pressure screen printing products such as: UV curing oil, colorful convex oil, cigarette packs, wine boxes, self-adhesive color printing, is a better choice.
Vertical horizontal screen printing scraper is pneumatic type and electric type (horizontal printing power), electric type USES frequency conversion motor, its speed even, no strings, no shaking, is printing, high-precision branch circuit board's first choice. And at the time of the low speed pneumatic type has a walking motion, it is only suitable for high speed printing, paper flowers in ceramic screen printing (especially when printing gold paste), can print out the pu ink layer, cost savings.
Comprehensive described above, the choose and buy screen printing machine based on:
Products 1. What he had done (branches or the color design, printed circuit board or printed paper).
2. The budget of the purchase price (remember that oblique arm machine is can't print out the stable precision of network).
3. The required accuracy (vertical machine for printing error is less than 0.02 mm, oblique arm machine is less than 0.05 mm, can meet the requirements of general overprint. Overprint accurate crux in positioning fixture is reasonable and the quality of workers).
4. Select models size: economic conditions allow to choose a, convenient later do business of large size (can't choose too big, otherwise feeding difficulties).
