Stainless Steel that has been pickled, and abrasive cleaning back to new

Even in our own manufacturing process there comes a time when we need to clean a part due to a failure or unique situation. Fortunately, we have test blast equipment at our disposal, for the use of our customers, prospects and an endless amount of cast zinc shot.

The Goff 1.5 Cubic Foot Tumble Blaster Controls Upgrade

In 2023, Transmet, a leading manufacturer and supplier of rapidly solidified metals, faced several challenges with their mid-1970’s Goff Tumble Blaster.
Other

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.
Other

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.
Zinc Shot

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.
Zinc/Aluminum Shot

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.
Aluminum Shot

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.
Zinc Shot

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.
Zinc Shot

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.
Zinc Shot/SSG

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.
Zinc Shot

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.
Zinc/Aluminum Shot

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.
Stainless Steel Grit

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.
Zinc/Aluminum Shot

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.
Zinc Shot

Replacing Aluminum Oxide to Reduce Shot Blasting Dust

Companies are consuming massive quantities of Aluminum Oxide every month and generating a lot of dust.
Zinc Shot

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.
Zinc/Aluminum Shot

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.
Zinc Shot

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.
Zinc Shot/Shot Lab

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.
Zinc Shot

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.
