So, you can load each of the chamber with individual parts and polish them simultaneously without any part to part contact. So, no damage will happen to the parts.

The manufacturing of the aluminum investment casting itself is a complex task. So, you need to be very careful in polishing the investment castings. It demands for high level of accuracy and consistency.

The centrifugal disc finishing machine can be used to polish the aluminum investment casting parts. You need to select the media in such a way that it does not create any lodging issue during polishing process.

The process of lost foam die casting is almost similar to that of the investment casting. Here, the foam is used to create the casting pattern.

You will need a high precision mass finishing machine here. So, you can invest in the centrifugal disc finishing machine for best results. Select appropriate media to ensure that you get the desired finish on the parts.

Many artworks are made of aluminum sand castings. The surface of the manufactured product will be rough. So, proper smoothening is essential to get the final finished part.

The choice of the machine will depend on the size of the artwork. If the parts are large and complex, then you will have to go for the tub vibratory finishing machine. For small and medium parts, the standard vibratory finishing machine will be sufficient.

The small sand casting parts also require proper polishing to get the finished part. The details in the artwork will be visible through polishing only. The choice of machine can be anything.

You can use the centrifugal disc finisher machine, rotary barrel tumbler machine, or the vibratory finishing machine. The choice is yours. You need to select the right type of vibratory tumbling media also.

Aluminum die cast parts are commonly used in automotive parts. These parts demand high quality finish on its surface. So, proper polishing is essential. Sometimes, the parts need to go for further processing like anodizing or electroplating. So, surface preparation will be needed.

You can either use the vibratory finishing machine or the tub vibratory finishing machine for polishing automotive aluminum die cast parts. If you want to get more shine on the parts, then you must polish it for more time using a less abrasive media.

Vibratory Media For Cast Aluminum Polishing

Polishing Cast Aluminum Parts – Definitive Guide

Are you into the business that deal with cast aluminum parts?

Many businesses make use of cast aluminum parts.

The different sectors include the aerospace, defense, automotive, mechanical, electronics, medical, and many more.

If yes, then thus guide is for you.

You will learn about the various surface finishing machines and vibratory tumbling media options from Inovatec machinery for polishing cast aluminum parts.

You will also understand the benefits of using a mass finishing for surface finishing over the traditional manual polishing methods.


1. What Do You Mean By A Cast Aluminum Part?

Aluminum parts are manufactured using different process like casting, forging, stamping, etc.

When the aluminum part is manufactured using the casting process, then such a part is called cast aluminum part.

Here, the aluminum in molten form is poured on to the mold to create the parts.

Die casting, permanent mold casting, and sand casting are the three popular casting techniques used for manufacturing aluminum cast parts.


2. What Are The Benefits Of Polishing Cast Aluminum Parts?

The advantages of polishing cast aluminum parts are many.

The benefits are listed below.


2.1 Superior Finish Quality

The quality of the final part matters in any type of business.

The manufactured part will have lots of imperfections in it.

It will be visible in the form of burrs, pits, and scales.

So, you need to remove it to get the final finished part.

So, polishing is required on these parts to remove all these imperfections.

Different aluminum parts will have different polish requirements.

Some parts will need a matte finish whereas others many need a glossy finish.

The level of finish also varies for different parts.

You can achieve all types of finish on the parts through proper polishing.


2.2 Part Strengthening

The pits and burrs in the part after the manufacturing of the part will weaken the part.

So, these imperfections need to be removed from the parts.

The polishing will help to remove all such weak spots and thereby strengthen the part.


2.3 Block the Oxidation Effect

The cracks and pits in metal parts make it prone to oxidation.

So, removing it will help to protect the parts from getting tarnished due to oxidations.

A proper polishing will help to protect the cast aluminum parts from oxidation.


3. Can You Explain The Traditional Method Of Polishing Cast Aluminum Parts?

The wheel grinding method is used earlier for cast aluminum polishing.

It needs human laborers.

It can be done in two ways.

One of the method use a mobile grinding wheel.
