While both blades are effective in many applications, each material offers some benefits and disadvantages. Metal blades are typically more rigid and durable, while plastic edges are softer and can wear out sooner. Also, they usually require more frequent replacement, increasing the amount of press downtime and degrading the print quality.

Plastic blades are more durable

Plastic blades are more durable than steel and are more resistant to abrasive chemicals. They also have a low friction coefficient and self-lubricate coefficient, reducing blade changes’ frequency and increasing the life of printing presses. However, these benefits come at a cost.

Fiberglass blades are available in a wide range of thicknesses. They are handy for board and paper substrates and line work. They can be used on larger ceramic anilox rolls and inks with higher abrasive concentrations. These blades are available in SLR (15-degree bevel), 20 and 25-mil thicknesses.

Steel blades are better for printing applications because they have a more extraordinary memory, but top-quality synthetic blades are far superior. They have better control over ink, which is essential to printing. They also have less spitting than plastic blades.

Metal blades are more durable

The printing industry faces several pressures from the market. Steel blades can be difficult to handle and can cause injuries in the press room. As steel wears, its borders become razor-sharp, posing a severe risk to press operators. Plastic blade technology offers a viable alternative that delivers a competitive edge. Plastic blade technology also helps to reduce costs. These advantages can make plastic blades the right choice for your printing needs.

A plastic blade has a lower coefficient of friction than a metal blade. This translates to a longer life. Plastic blades are also thicker than composite or metal ones, which leaves more surface ink on the roller. However, they have less consistent print quality and can be subject to deformation due to friction. This can result in dot gain and hard particle damage.

Plastic is the most common material in printing applications, but metal blades are much stronger and more durable. Metal blades are also more resistant to wear and tear, making them the best choice for printing applications. They are also more cost-effective, as they typically last longer and cost less. However, you should make sure you research your options before purchasing.

Nonmetallic blades are easier to handle

There are a number of advantages of using nonmetallic blades in printing applications. First of all, nonmetallic blades are safer to handle and will save your company money in workman’s compensation insurance rates.

Another advantage is that nonmetallic blades will last longer. Most steel blades wear out quickly and will need to be replaced frequently. On the other hand, nonmetallic blades will last longer and require fewer changes. Because they have a lower coefficient of friction, nonmetallic blades will require less maintenance and repair. As a result, you will reduce press downtimes and keep your press running for longer.

Another advantage of nonmetallic blades is their ability to resist ink. 

Nonmetallic blades are ideal for coating sheetfed offset printing applications. The use of a nonmetallic blade will minimize pressroom injuries and maintain a safe pressroom environment.

Nonmetallic blades are an excellent choice for printing jobs because they are non-magnetic and less likely to be damaged by ink. The material used to make them is also lighter, making them more ergonomic for the hands. They are often coated with other materials for extra durability. In addition to being lighter, nonmetallic blades can be printed with stylish patterns and colors.
