SHOT BLASTING OPERATIONS *What is Shot Blasting? High-production shot blasting is utilized for mass cleaning of parts in foundries, forging shops, heat treat companies, or fabrication facilities. Shot blasting machines and blast media blasts-away surface rust, scale and contaminants and prepares the part for the next step of production. Shot blasting is a general process using a random mixture of steel shot/steel grit for all-purpose surface cleaning and preparation. In summary, shot blasting provides mass cleaning while shot peening improves the strength of the part with a technical and repeatable process. Learn more about shot blasting via our Intro video. *Do you offer used and rebuilt GOFF shot blast machines as well as new shot blasters? Yes. We offer new, used and rebuilt GOFF shot blast machines with warranty packages and start-up training after installation. Downloadable GOFF brochures on all models are available for free. *Do you offer special terms of payment for a GOFF shot blasting machine? Yes. We offer many special payment plans (including rental packages) with cash discounts, minimal down payments and/or 30, 60, 90 and 120 day finance plans. We also offer 36, 48 and 60 month leasing agreements. *Do you offer warranties? Yes. We offer one-year and two-year warranties for our shot blast machines and systems. *Why do companies purchase shot blasting machines VS hand cabinets or air-blast rooms? The blasting of parts through a mechanical nozzle leads to high electric bills, major media consumption, and extreme maintenance costs. Whereas airless shot blasting uses a mechanical slinger device connected to a direct-drive motor to propel the blasting media. This offers much lower costs of operation. This centrifugal blast wheel consumes 15 times less energy, provides 15 times more production and is 15 times less expensive to operate than air-blast equipment. *Which companies or industries seem to rely on the shot blasting process the most? The major companies are foundries, forging, heat treating, structural steel & weldments, coatings, and automotive rebuilders – almost all companies that use shot blasting are related to the Automotive Industry sector. We also sell to the Railroad and Trucking industries and work with manufacturers in the Gun industry. See all the industries we serve here. *On what materials or equipment would one NOT want to use a shot blasting machine? Shot peening and shot blasting machines are very aggressive and high-production oriented (Automotive industry). Delicate parts-cleaning such as restaurant equipment or medical supplies do not work well with shot blasting. *Is there a general time-frame for how long it takes when using a shot blast machine for a blast cleaning session? Yes. Goff shot blasting machines generally clean the parts in 30 seconds to 2 minutes. Almost nothing is blasted longer than 5 minutes, even in 1,600 lbs. loads. *Are there any facility requirements to keep in-mind before installing or using shot blasting equipment? Yes. All shot blast machines require a dust collector to ventilate them, and therefore, duct-work is required for installation. Goff shot blast machines are easy to install and shouldn’t take more than two days to set up. *Does Blast-Abrade and GOFF run-off equipment with steel shot prior to delivery. Yes. All GOFF shot blast machines are run-off with steel shot to ensure proper operation. Our customers are encouraged to attend the ‘proof run-off” prior to shipment. *Does the steel shot used in shot blasting operations come with the purchase of a new or rebuilt Goff shot blaster? Does Blast-Abrade sell additional steel shot? The steel shot media is widely available at industrial supply warehouses. Yes, Blast-Abrade stocks and sells shot-blasting abrasives that include cut-wire media and exotic stainless steel shot/grit. *How much compressed air is needed for a GOFF shot blast machine to operate? The typical GOFF blaster requires a minimum 4 CFM (or 1 HP of compressed air) to operate the abrasive valves, pulse the dust collector valves, or open a door by initiating the air cylinder. *What is an air-wash separator? An air-wash separator is used to clean the media as it flows through the shot blast machine. The shot blast media is propelled at the parts, then fed through the reclaim system, and then dropped down through the air-wash separator. A ‘waterfall’ curtain of media is created as it passes through. Air is pulled through the ‘waterfall,’ which removes all the broken-down media and other contaminants. The good and usable steel shot/grit drops back into the primary storage hopper where it repeats the process by feeding into the blast wheel again. *Why is vibration bad for shot blasting equipment? Blast-wheel vibration is an indication of serious wear on the blast wheel or bearing failure on the 3600 RPM blast wheel motor. The vibration means that the blast wheel is out of balance and will require service. *What is included in a Tune-Up Kit for a GOFF blast wheel? A tune-up kit includes: blades, impeller, impeller bolt, control cage and appropriate seals. The tune-up kit for a blast wheel should be replaced periodically for maximum blast efficiency and reliable P.M. Programs.
