Delrin—What Is It?

Delrin® is a thermoplastic material used in moving parts that require low friction and long wear life. Products made of Delrin® are tough, have high impact strength and high resistance to repeated impact. Additionally, Delrin® has high tensile strength and creep resistance, and exhibits low moisture absorption. Its chemical resistance to hydrocarbons, solvents and neutral chemicals make Delrin® ideal for many industrial applications.

Delrin® – also known as Acetal Homopolymer (POM-H/Ertacetal H®) – parts are easily machined and its strength and high abrasion resistance make it a good replacement for metal if the full strength of metal is not required.

Pad Printing

Achieves extremely fine detail and tight multicolor registration.

Pad printing is a printing method that allows the transfer of a 2-dimensional image onto a 3-dimensional object. While just as effective for flat surfaces, this process is most often used for printing on parts that are round, have complex curvature, that are round, have a concave or convex surface, or have recessed or raised areas. 

Pad printing became popular following World War II when watchmakers began printing on the curved surfaces of watch faces. This ability to print on unprintable substrates has turned the pad printing process into a well-established technology and is used today across multiple industries such as medical, cosmetics, electronics, and more.

Screen Printing

The most economical choice for projects that have a single, large image. This process produces very opaque images.

Screen printing is a printing method that allows the transfer of large opaque images onto flat (or relatively flat) and cylindrical plastic, glass, and metal objects. The origins of screen printing date back thousands of years — from early Polynesian natives who forced die through cut-out patterns in banana leaves to decorate cloth, to cave walls found in France and Spain that were decorated by way of stencils and colorant applied with blowpipes, to the Japanese creating intricate designs during the Sung Dynasty (A.D 960-1280). Today, screen printing is used to decorate rigid parts for a variety of industries.
