OtherAltering blast media size to improve blasting cycle time
A customer was looking to achieve a uniform finish with a specific surface profile in a shot blasting operation. With a recent influx of orders, the customer had difficulty keeping up with demand and the shot blasting step became a bottleneck issue.Read the full Case Study
Reduce reject rate from blast media contamination
Customers were blasting aluminum parts and needed a more gentle media to match the hardness of the substrate.
Altering blast media size to improve blasting cycle time
A customer was looking to achieve a uniform finish with a specific surface profile in a shot blasting operation. With a recent influx of orders, the customer had difficulty keeping up with demand and the shot blasting step became a bottleneck issue.
Inhibit flash rust on ferrous parts after shot blasting
Customers are cleaning ferrous parts prior to processing and/or painting. The methods being used are either steel shot blasting or chemical cleaning to prepare the surface for subsequent operations.
Applications requiring less aggressive blast media
Steel shot, glass bead, and sand are the most widely used blast materials in the world. They are all readily available and work well in many applications because they are very aggressive.
Considerations when replacing steel shot with aluminum shot
Transmet is frequently asked what to consider when replacing Steel Shot with Cast Aluminum Shot. Cast Aluminum Shot is one-third the density of Steel. If not accounted for, this difference can cause the dust collection system to remove usable shot from the blast machine.
Why are there so many different hardness scales?
From pure metals like zinc, aluminum, steel and tungsten, to plastics, cork, a fingernail and everything in between, there’s a hardness scale associated with its chemical makeup. But not every metal or material can be tested the same.
Testing the durability & Agressiveness of shot alloys
Testing shot products in the field is time consuming and not practical. Changing media sizes and alloys is difficult in production equipment.
Cleaning Aluminum Cores for Remanufacturing
Blast cleaning aluminum cores can be difficult, balancing the need to clean with the need to preserve detail on the cores. Cleaning with steel shot or other aggressive media cleans fast, but destroys mating surfaces and threads, resulting in additional grinding or re-treading to repair the damage.
Preventing Rust After Blasting Ferrous Parts
In hot humid summer months many companies struggle to prevent blasted parts from rusting after blasting. Painting immediately after blasting isn’t always practical.
Solving Excessive Wear Issues in Cylinder Refinishing Industry
Companies refinishing compressed gas cylinders for various industries have historically used steel shot to clean rust from the tanks prior to hydrostatic testing and re-painting of the cylinders.
Maintain Consistent Surface Finish on Delicate Castings
Transmet Cast Shot is relatively soft compared to many other blast materials. The shot is cast in air, resulting in a teardrop shape that flies in the face on conventional shot peening norms.
Shot Blasting Applications For Stainless Steel Grit
For decades, sand was the standard media for shot blasting. Sandblasting was developed by Benjamin Tilghman in 1870 when he produced a machine to strip away rust and paint from some surfaces. It was extremely effective for the time period until safety became a concern.
Replacing Vibratory Finishing with Dry Shot Blasting
Vibratory finishing is a time-consuming and chemically-intensive process that requires the proper balance of media and cleaning agent.
Replacing Aluminum Oxide to Reduce Shot Blasting Dust
Companies are consuming massive quantities of Aluminum Oxide every month and generating a lot of dust.
Die Casting Porosity Issues, Delamination from steel shot
This custom zinc die casting company from Wisconsin was casting a zinc part that required a highly cosmetic surface finish.
Reduce Blasting Reject Rate on Remanufactured Parts
Steel shot, glass bead, and mineral abrasives are the most commonly used blast media in various remanufacturing operations. They are all readily available, but can be too aggressive for many remanufacturing activities.
Cleaning Carbon, Rust, Paint from Bearing Components
A remanufacturer of mild steel bearing components needed to remove carbon buildup, rust, and old paint from their components.
Eliminate Welding and Grinding after Shot blasting aluminum sand castings
Using steel grit for blasting aluminum and castings resulted in a dull gray finish on the surface of aluminum castings and frequently opened porosity on the surface of the castings.
Shot blasting results after replacing zinc cut wire
Reduce blasting cost by finding a more effective media to work faster and last longer, without damaging the delicate detail of the parts.
How Abrasive Blast Media Durability Relates to Dust
Transmet is frequently approached by people in various positions with concerns about the amount of dust generated in their plant from shot blasting (abrasive blasting) operations.
