How the Blasting Process Works

Understanding the operational workflow helps you evaluate the machine's suitability. The process typically involves loading the part, initiating the blast cycle, and unloading. In a table type machine, the part is placed on a rotating table. Blast wheels direct the abrasive media at the part from multiple angles. The cycle time depends on the part size and the desired surface finish.

Step by Step Process

First, the operator loads the part into the machine. The machine seals to contain dust and media. The blast wheels activate, and the media is propelled at high speed. The part rotates to ensure even coverage. After the cycle, the machine opens, and the part is unloaded. The media is recovered and separated from dust and debris. This cycle repeats for each part.

Automation and Control

What Drives the Cost of Blasting Equipment

The cost of a shot blasting machine varies based on several factors. The size of the machine, the number of blast wheels, and the level of automation all impact the price. Larger machines with more wheels and advanced controls will cost more. However, the initial cost is only part of the equation. You must also consider the cost of media, maintenance, and energy consumption.

Initial Investment Factors

The machine type is a major cost driver. Table type machines are generally more affordable than large hangar type machines. Tumblast machines, which use a rotating drum, are often used for smaller parts and can be cost-effective. Synco Industries offers a range of options, from the 16x22 tumblast machine to the 36x42 model. The choice depends on your production volume and part size.
