What is a sandblaster?

A sandblaster is also known as a sandblasting machine or abrasive blasting machine. It is vital in shooting out paints, rust, and coatings from varieties of durable materials such as metal, brick, and wood.

It is often used for surface preparation methods in construction, automotive, and marine industries. They are also essential in etching or cleaning stone, glass, and other materials. The metal fabrication industry commonly uses sandblasting equipment.

Types of sandblasting machines

There are various types of sandblasters. But, only the most common ones will be covered in this article.

1. Handy sandblasters

When choosing a sandblaster, consider the industry and specific requirements of the project. This is because industry requirements differ from one to another. 

For instance, the construction industry requires sandblasting machines that can shoot large areas swiftly. The automotive industry, on the other hand, will need high-precision machines that should blast small components.

Here are some vital factors to consider before choosing a sandblaster:

Select a suitable abrasive

Understand that there are various types of abrasives in the market with their merits and drawbacks. A suitable choice of abrasive will depend on the material for blasting and the desired finish. Here are some common types of abrasives:

Aluminum oxide: A popular choice for blasting metals. It is economical and fast-cutting, making it a good choice for the metal industry.

Walnut shells: This soft abrasive is used mostly for delicate surfaces such as stone and wood.

Glass beads: For cleaning aluminum casting, stainless steel parts, and automotive parts, this abrasive is one of the most common choices. It produces a smooth and glossy finish.

Item size and weight

The weight and size of the item for blasting will determine the type of equipment one needs for the project. For instance, to blast small parts such as a car’s piston or brake calipers, a container sandblaster would be a perfect choice.

But if the item for blasting is a large component, such as a car’s chassis, then a blast cubicle would be a more suitable choice.

Automation level

Most people consider an automated machine the best choice because it’s more precise and suitable for extensive projects. But it is only ideal for some projects, and may be less suitable for others, especially if there are any budget restraints.

A manually operated sandblasting machine may be adequate if there are only a few items for blasting. But if you need a consistent result without any error throughout, go for an automated system if the project volume is large.

Features of the best sandblasting machine

Before buying a sandblaster for your specific needs, decide on the project you will use it on. To help you achieve that, here are some features of the best sandblasting machines:

– Solid tires

– Big fuel tanks

– Adjustable pressure controls

– Big hoppers

– In-built lights

– Multi-abrasive material capabilities

The bottom line

Choosing the right sandblaster will depend on the business and its unique requirements. But the challenge of selecting a suitable model will be reduced by keeping in mind the key points to consider shared in this article, which will help businesses to find a suitable machine for their specific needs.
