In the automotive industry, surface preparation is not a final operation. It is a condition for the product being safe and reliable. The applications, though, differ enormously from each other, and the equipment that suits one is wrong for another. Cleaning castings Foundry parts arrive in the automotive industry carrying moulding sand, burrs and oxides. […]

Blasting and shot peening look like the same thing. From a subcontracting point of view, they are not. Blasting: a visual result In blasting, the result is assessed mainly visually: the degree of surface cleanliness and the roughness achieved. You agree the grade, the work is done, verification is by comparison. The conversation is simple

Not every company that needs vibratory finishing needs a vibratory finishing machine. Subcontracting means you send the parts and someone else processes them on their equipment. You get finished parts back, with no capital tied up. How it works 1. A trial on your part. No serious supplier quotes before seeing the part. A few

A dust collection system produces nothing. It shortens no cycle and adds no value to the part. That is why the classic payback calculation does not work. What you calculate is what it prevents. What it prevents Shutdown. Without compliant dust capture, operations can be suspended. This is the cost nobody budgets and the one

The cheapest consumable per kilogram is often the most expensive per part. This is where most money leaks in a finishing shop, and the leak is quiet. Why price per kilogram misleads An abrasive costs 30% less but is consumed twice as fast. You paid more, but each invoice looks better, so nobody notices. The

In vibratory finishing, cost per part can be calculated. Not exactly, but close enough to make a decision. You start from one thing: how many parts fit in a batch. Step 1: how many parts go in Part volume in the bowl comes from the machine’s working volume and the load ratio. The usual ratio

The question “what does a blasting machine cost” has no answer, because it has no object. A manual cabinet and a wheel blast line with a conveyor are both “blasting machines” and differ by an order of magnitude. What can be given is the structure of the cost. With it, you can compare quotes and

Practically every forming process leaves burrs. Casting, stamping, cutting, machining — all of them produce sharp edges that vary widely in shape. Burrs on parts machined at an angle are the hardest to remove. Why they are removed A burr is a sharp edge that cuts the operator’s hand, obstructs assembly and collects excess paint.

The tunnel washing machine works on one principle: the part moves forward, the stages come to it. Parts sit on a stainless steel conveyor belt and pass through four successive zones. The four stages 1. Degreasing. An aqueous detergent solution, usually heated to 50–80 °C, is sprayed through nozzle manifolds from every direction. Temperature matters:

Industrial washing cleans machined parts before the next operation. It removes machining oil, metal chips, grinding dust and residue left by earlier steps. This is not cosmetic. It is a technical condition. When it becomes mandatory Parts go through casting, stamping, machining or welding. Each of these leaves residue. If the part moves on dirty,
