molded product surface, there are several common methods to make Logo and patterns on the molded fiber products surface:

1Method of die casting

Logo and various patterns are engraved on the heating molds. In the production process of molded pulp products, the wet blank is transferred to the heating molds for hot press mold solidifing, and the dry finstereotyped surface of the product naturally has the corresponding Logo or a variety of patterns.




The Logo and patterns produced by molded die casting are relatively simple, Logo and patterns are convex and concave on the product surface.It is hard to die cast on the product side with the mesh linest to form a clear and obvious pattern, so the pulp mold Logo and the pattern are often on the smooth side without mesh lines. The pattern is generally designed in the plane smooth side without mesh lines.

The Logo and patterns produced by die casting also require some pressure to form a clear pattern on the pulp molding surfaceTherefore, the Logo and patterns of molded pulp products should not be printed on the angular surface of the product but in the plane.

In summary, if the die casting method, the pattern is generally designed in the plane and smooth side without mesh lines.


2The method of making trademark and pattern of molded fiber products surface by laser

The method of making the Logo and patterns of the surface of the molded pulp products by laser is to use the laser to illuminate a certain part of the molded fiber products to steam or change the color, thus leaving a permanent mark.Lasers can produce various kinds of words, symbols and patterns on the surface of molded pulp products.Through laser beam action on the surface of the molded fiber products, make the molded fiber products surface to produce physical and chemical reaction, evaporation of the shallow fiber of the molded fiber product surface to leave traces, so this logo trace is permanent, difficult to tamper with and wear, and generally will not fade.




3Inkjet printing method of surface patterns of pulp molded products

Molded fiber production pattern ink jet printing method, is the use of charged ink particles, from the high voltage electric field deflection principle, on the surface of various pulp molding products spray printing pattern text and digital, is a high-tech product.


At present, the more successful digital injection code machine is UV injection code machine, UV injection code machine is using professional uv ink injection printing injection code machine, drying speed fast, good luster, bright color, water resistance, solvent resistance, good wear resistance characteristics. There are two kinds of UV spray code machine, one is high definition and the small character UV spray code machine, which is the new product, and is the perfect combination of UV technology and small character technology. Simple maintenance cost is low, stable and reliable operation, completely break through the shackles of the traditional code injection machine.

Making signs and patterns can make the surface colorful. Molded fiber food packaging and molded pulp industrial packaging such as molded pulp tableware,molded fiber (pulp) tray/ plate, molded fiber plates and bowls, pulp molded pulp cup lids , etc., can make various patterns and signs on its surface.
