AQS is a leading worldwide supplier of pneumatic score knife holder assemblies. We produce more than 5,000 slitter blade holders each year and offer a knife holder superior to many on the market with exact width size, clean movement, and secure knife fit. Our Pneumatic holder is compatible with all PQAS style holders currently on the market. Applications of these score knife holders fall within score slitting, crush cutting, pinking and perforating. We have a number of different styles of blades that can be used with these pneumatic holders available in our inventory or for custom production.
Our pneumatic holders are available in a standard black oxide finish or with a ‘friction free’ coating that reduces heat and extends holder life. Heat is a primary factor in score knife holder failure. Our solution is to slick coat those items influenced by friction. Each pneumatic holder is assembled, tested for leakage and smooth operation. Thickness is checked with precision micrometers and is held to ±.001″.
Our Gold Standard holders have a titanium skin, allowing the knife to operate with less friction while preserving holder life. The skin is harder than the knife itself, as the titanium’s increased hardness and lubricity resists high heat from friction and adds additional protection against warping. These holders are ideal for high-use applications and where abrasive materials are cut. This coating also offers a corrosion-free or rust resistant solution for corrosive environments, making it perfect for food-processing applications. When combined with one of our stainless-steel knives, the assembly resists corrosion well enough to be cleaned by simply spraying with water.
American Quicksilver offers a wide array of spare parts for all of our pneumatic holders. All AQS score knife holder parts are 100% interchangeable with units currently on the market. The holder spacers and holder side plates are hardened and precision ground. For both of our score holder styles, there is the option to install the Quickclamp. This quick release lever serves as a speedy clamp and release option for easy access and maintenance of score holders already on the dovetail bar. You have the option of having these installed in-house or for purchase separately. For more information regarding our holder parts, please click here
