Inovatec Machinery The Leading Engine Block Polishing Solution Provider in China

Engine blocks house the pistons. It is also where combustion happens. Engine blocks are generally made of aluminum, cast iron, stainless steel, etc. Besides, the engine block must be polished before it’s assembled.

Inovatec Machinery offers a variety of polishing solutions. It includes engine block polishing as well. Inovatec has been in the mass finishing equipment business for the past 20 years. As a result, they have immense experience and quality products.



Tub vibratory finishers are unmatched when it comes to engine blocks. It is because these machines are specifically designed to accommodate large workpieces that other devices cannot fit.

However, engine blocks are delicate and need to be handled with care. The TVB(B) model is perfect for engine block polishing. It is quite efficient and safe for use. It has straight walls inside which provide maximum protection.


This is the second type of vibratory tub machine offered by Inovatec. Though, it looks quite similar to the TVB(B) model. It is designed to have an open tub with curved walls. The spacious container can not only accommodate engine blocks, but other things as well.

The tub also has additional suspension under it for excess vibration. It ensures that the amount of vibration caused inside the machine is as balanced as possible.

Polishing for Different Types of Engine Blocks

V engines are some of the most popular engines you will find out there. Some examples of V engines include the V6, V8, V4, etc. These engines are quite powerful, and automotive enthusiasts love them.

However, no matter the engine, it needs polishing. Every part of the engine needs to be super shiny and smooth to perform well. Since the V engines are large, you should opt for a TVB(A) engine for its finishing.

We don’t usually use stainless steel engines, but they can still be found. Despite this, stainless steel engines are robust, durable, and quite cheap. For this reason, they need careful polishing before they are installed.

To polish this type of engine, use a vibratory tub  finisher. Specifically, use the TVB(A) model. These machines have open space, which can accommodate the size of the engine adequately.

We usually use inline engines for our daily commutes and as displacement engines. The name ‘inline’ comes from its design. The engine has cylinders placed in a line. The number of cylinders varies from four to six to eight.

To polish this block engine, use a tub vibratory machine. You can choose either the TVB(A) or TVB(B) model for this purpose.

We use cast iron blocks in daily commutes as well as fast cars. Cast iron is an excellent choice for an engine. It is durable, efficient, and long-lasting.

To polish a cast-iron block, use the TVB(B) vibratory finishing machine from Inovatec.

The boxer engine is quite controversial. These engines come equipped with two cylinders on the opposite ends. This design helps balance out the vibrations. It’s a fantastic way to stabilize an engine. However, all good engines are polished before use.

To best polish a boxer engine, use the TVB(A) vibratory finishing machine from Inovatec. Since boxer engines are quite complex, you should polish each part separately.

Aluminum is another excellent material used in engines. Aluminum is very lightweight yet sturdy, which makes it very efficient. You also need to polish aluminum cast engines to make the most of them.

To polish these, you may use any of the two tub vibratory finishers offered by Inovatec.

Engine Block Polishing Media

Engine blocks have small crevices and nooks that are hard to reach manually. As a result, they need mass polishing. And for mass polishing, you will require polishing media. For engine block polishing, non-abrasive media is the best choice. Some good examples of this are porcelain media and plastic (synthetic) media.

Engine Block Polishing – The Definitive Guide

Are you someone who deals in engine parts?

If yes, then polishing them is a matter of everyday routine.

Engine blocks house the piston as well as the combustion process in machinery.

Most engines are made of stainless steel, cast iron, and aluminum.

After you manufacture an engine, polishing it becomes necessary.

Keep on reading to find out how you can easily carry out the polishing process for engine blocks.

1. What Types Of Vibratory Media Is Suitable For Engine Block Polishing?

Engine blocks are very complex and delicate. You need to handle them properly.

Plus, blocks have small crevices that are hard to reach by hand.

To polish these areas, you would require cleaning media.

1.1 Porcelain Media

Porcelain is mostly made of clay. However, it partly contains alumina and kaolin, which are ceramic-based.

The difference between porcelain and ceramic is that ceramic is abrasive towards certain sensitive parts. This is not the case with porcelain.

Porcelain is perfect for wet polishing. It gives you favorable results and also helps in the removal of dust particles from the metal.



1.2 Plastic Media

Plastic media is suitable for reducing part-on-part contact during the finishing process.

Synthetic media is usually made up of abrasives like alumina, zirconia, and silica. It also contains polyester resin, generally in a half-and-half ratio.

You can purchase synthetic media in the shape of a cone, paraboloid, and more. The sixes range from 6 mm to 100 mm.

Plastic media gives a smooth finish and does not damage your parts. It also lasts a very long time.


2. What Types Of Engine Block Polishing Machines Are There?

Inovatec offers two types of engine block polishing machines:


2.1 TVB(B) Tub Vibratory Finishing Machine

This machine can support large engine parts that other devices cannot.

These finishers are incredibly useful and ensure the safety of your parts too.

The safety element comes from the straight walls of the machine.

The TVB(B) finisher also has compartments to hold separate parts of the workpiece.

These compartments eliminate the chance of any damage caused to the parts due to part-on-part contact.

In addition, the machine is suitable for intricate and delicate parts.



These are the reasons for which this machine is ideal:

  • Polishing of a cast-iron engine block
  • Polishing of an inline engine
  • Polishing an aluminum cast engine block


2.2 TVB(A) Tub Vibratory Finishing Machine

This is similar to the TVB(B) model, except this one has curved walls instead of straight ones.

These machines are also large and can accommodate large and bulky parts.

The machine also has a suspension under it to handle any excess vibrations.



The suspension also makes sure that the vibrations are balanced.

The TVB(A) machine is ideal for the following:

  • Stainless steel engine blocks polishing
  • V engine blocks polishing
  • Inline engines polishing
  • Boxer engines polishing
  • Aluminum cast engine block polishing


3. For Engine Block Polishing Operations, Why Choose a Tub Vibratory Finisher Over Other Mass Finishing Machines?

The first reason is that vibratory tub finishers are massive machines. And since many engine blocks are big, they are perfect for these machines.

The compartments in the machine prevent part-on-part contact during the process. It also reduces any harm that may come to the parts.

Engine blocks also have tight crevices that only tub finishers can reach.

A tub finisher also ensures that the dimensions of the block are maintained.

Other machines can damage engine parts and modify their dimensions. A tub finisher does not do that.


4. How Does The Engine Block Polishing Machine Work?

The polishing machines vigorously shake their troughs.

The shaking motion creates friction between the polishing media and the parts.

Friction helps out the process by a lot because it rids the engine of any blemishes or debris. As a result, the engine block performs well.

5. How Long Will It Take To Complete An Engine Block Polishing Cycle?

The vibratory finisher is quite fast in completing the process. However, this can depend on many things:

First, you need to consider the intensity of the polish you require.

The longer the engine stays in the machine, the more intense the polish.

To add, the type of media you select will affect the duration of the process.

The more abrasive the media, the faster the process will be.

Besides, the material of the engine block also impacts how long it’ll be polished.

For example, an aluminum engine block will polish faster than one made of cast iron.


6. What Are The Benefits Of Polishing Your Engine Block With Inovatec Polishing Machines?

The following are the benefits of using Inovatec polishing machines:


6.1 Consistent Polish

It’s vital for an engine part to have an excellent final finish.

When you use a mass finishing machine, rest assured that you’ll receive consistent results in return.

Whether you’re looking for a shiny finish or a dull one, Inovatec has the solution.


6.2 Facial Appeal

The facial appeal of a product is valued in any industry, and the mass finishing one is no exception.

By using a mass finishing machine, your parts will have a sleek finish.

To get high-quality results, invest in Inovatec Machinery.


6.3 Removal of Rough and Sharp Edges

After the manufacturing process, products are due to have sharp edges and burrs.

These sharp parts can be dangerous to handle.

Thus, you need to polish it.

With Inovatec’s efficient solutions, you can do this easily.

Safety is a massive part of any industry. By polishing your pieces, you are eliminating the risk of injury and any other incidents.


6.4 No Manual Labour, Downtime, or Damage

Polishing an engine block by hand takes time and is also super expensive.

To add, you cannot reach small crevices with manual polishing.

Using a vibratory machine is cost-effective, takes less time, and is very efficient.

Plus, there is less risk of damaging any of the parts.

However, remember to use the right polishing media according to the material of your engine block.


6.5 No Skilled Labour Required

For manual  labor, you require multiple people with a lot of skill. But with a mass finishing machine, all you need is one operator.

Notably, the operators do not necessarily need to be skilled at polishing themselves.

Inovatec Machinery ensures that their instruction manuals are easy to read and understand.
