Sorry, the last time I mentioned it was the rubber dumbbell 40

Uses of rubber cutters:

It is used for punching rubber standard test pieces before rubber product test.

The models of rubber dumbbell cutters are:

National Standard Type 1 Dumbbells.

The length of the cutter is 115mm*, and the narrow parallel width is 6mm

GB 1A Dumbbell Cutter Length 100mm * Narrow Parallel Width 5mm GB Type 2 Dumbbell Cutter Length 75mm * Narrow Parallel Width 4mm GB Type 3 Dumbbell Cutter Length 50mm * Narrow Parallel Width 4mm GB Type 4 Dumbbell Cutter Length 35mm * Narrow Parallel Width 2mm Dumbbell Cutter Length 100mm * Narrow Parallel Width 3mm Dumbbell Cutter Length 120mm * Narrow Parallel Width 10mm Dumbbell Cutter Length 150mm* Narrow parallel width 10mm dumbbell cutter Length 152mm * narrow parallel width 13mm right angle tear cutter Crescent tear cutter trouser type tear cutter.

All kinds of square cutters, ring cutters, rectangular cutters.

GB cutters, ASTM cutters, CNS cutters, JIS cutters.

If there are other sizes, it can be customized according to the requirements.

The material of the rubber dumbbell cutter:

1: The general ordinary type is 45 steel.

2: Chromium steel material T8, T10 material, (this material is better than 45 steel, high hardness, suitable for hard materials).

National Standard for Rubber Dumbbell Cutters:

Compliant: GB T528; gb/t529；gb/t 8083；GB T 15340, ASTM and other standards.

It may be a dumbbell guide, made of foam, brushed with black qi, and rolled tin foil on the side.

The process is different, the cost is different. That's what economics says.

It seems that the electroplating is also more complicated, and it is detachable, and the weight can be adjusted freely.

Personally, I think it's just a difference in appearance, and it's actually a fitness tool. The choice of dumbbells is mainly based on the weight, which varies from person to person.

Laminated dumbbells are cast iron wrapped with a layer of plastic

Electroplating dumbbells are cast iron that has been electroplated and polished

Now most of the dumbbells on the market are rubberized, if you choose dumbbells with rubber, you must pay attention to the comparison of the quality of rubber, some bad manufacturers use PVC from the old plastic furnace

There are also some black-hearted manufacturers that use cement instead of cast iron for the inner material of rubber-coated dumbbells, so I personally recommend buying electroplated dumbbells, even if they are rusty, you can still make paint, and electroplated dumbbells generally will not rust

Good luck

Laminated dumbbells are better.

If the plating is off, it won't look good.

Electroplating dumbbells are better than lagging rubber, first of all, the weight of electroplating is more reasonable, and there is rarely a phenomenon of insufficient weight, and secondly, the volume of electroplating dumbbells is suitable for exercise and cleaner. Although the rubber dumbbell is cheaper, but in terms of volume, it is not advantageous, and now there are many illegal traders with the cement poured into the rubber dumbbell, most of the weight of the rubber dumbbell is unqualified, I just bought the electroplating dumbbell, in fact, many times you are a little ruthless, after buying it back, you will find that you have made a good decision. Here's my suggestion, I hope you'll consider it.

It is recommended that you still have rubberized dumbbells.

Because since it's a dumbbell, I just want to be silent during the exercise, so that it won't affect other people.

I don't know the material inside, it may be ordinary rotten iron, I recommend buying electroplating, ** may be more expensive, but the electroplated is not rusty, not easy to damage, and can be used for a longer time.

First, the structure is different.

1. Rubberized dumbbells.

The rubberized dumbbell is provided with a rubber binding structure on the surface of the bell head, and the joint structure is convex or concave to increase the surface area of the bell head and the rubber bond, and increase the bond strength.

2. Electroplating dumbbells.

The whole is made of cast iron, which is hard and heavy, and the surface of the dumbbell is electroplated.

Second, the volume is different.

1. Rubberized dumbbells.

The rubberized dumbbells are slightly larger. When you need a lot of weight, too much weight and the size of the dumbbell may hinder the movement.

2. Electroplating dumbbells.

Electroplated dumbbells are small in size.

3. Advantages and disadvantages.

1. Rubberized dumbbells.

The advantage is that it does not damage the floor; The disadvantage is that it has the smell of plastic, and the quality is not good and it is easy to drop the slag.

2. Electroplating dumbbells.

The advantage is that the surface is smooth and refreshing, not easy to rust, and does not change color; The disadvantage is that it is easy to smash the floor.

Fourth, other types of dumbbells.

1. Dipping dumbbells: Generally, large weight does not choose dipping, and the dipping façade is easy to rust.

2. Painted dumbbells: similar to electroplating dumbbells, small in size and not easy to rust.

The rubberized dumbbell is a layer of plastic wrapped in cast iron, and the electroplated dumbbell is made of cast iron after electroplating and polishing.

Rubberized dumbbells: Rubberized dumbbells are composed of cast iron and rubber as a whole, and rubber of different thicknesses is wrapped on the surface of metal.

Advantages: Rubberized dumbbells are relatively safe to use and do not make loud noises.

Disadvantages: Rubberized dumbbells are bulky.

The rubberized rubber has a slightly stronger smell and it takes some time for the smell to dissipate. And the volume is also relatively large, but in general there is no effect on the movement, because most gyms use rubber. And there is a rubber layer on the outside, which will not smash the floor and will not make too much noise to others.

I agree with the above two views, and add that it is not electroplating, because it is just one more electroplating, and it will be worn off when exercising. There are also big brands to buy dumbbells, because the general amount is insufficient (especially the rubber-covered ones, not to hit you...).%& Don't believe you're going to weigh it!! Exercise is still enough, though.

To put it simply, the difference between lagging and electroplating is that lagging is made of garbage scrap iron, and then the outer layer is covered with a layer of glue to make it look better, which is a parallel import to put it bluntly. Electroplating is made of high-quality iron casting and plating on the outer layer.

Advantages and disadvantages of the two:

Lagging rubber, advantages, cheap, disadvantages, too large shape, heavy smell, a amount of skin damage will be over.

Electroplate. Advantages, beautiful appearance, small appearance, disadvantages, ** high, generally about twice as much as the lagging.

As far as I know, there is also a kind of dumbbell with water injection, how much weight and how much water you need, which is more popular abroad, and now it is not common in the domestic market.

It's harmful, but it's not a big problem and doesn't have an impact on your health, it's fine.

Its smell is only due to: the smell of raw rubber (or reclaimed rubber) or peroxide system DCP. The order may be vulcanized with odorless DCP, and the taste is still there, but it will be smaller.

In addition, if the rubber-coated dumbbells are very poisonous, those who sell dumbbells are the first to be poisoned.

One of the elements of choosing rubberized dumbbells is that there is no taste, and those with taste are unqualified raw materials, and long-term use is harmful to the human body.

A good rubberized dumbbell doesn't have any flavor.

It is said that washing with gasoline will remove the odor, so you can try it.

I use iron, it feels very good, if you are afraid of scratching your hands, you can wrap a small handkerchief on the handle I have a friend who uses full glue, after a long time of full glue, the epidermis will age, and some rubber crumbs will fall off, and it will be very troublesome to clean up. Rubber products are certainly not as durable as iron products, and although iron products will rust, they will not hinder muscle training.

I recommend buying a better one, after all, in today's society, you get what you pay for, and the better one can be used for a few more years.

To be Schwarzenegger...

I think both glue and iron are fine!

My friend in school (I'm a sophomore, and my friend is a sports student) uses iron, and his muscles are now very strong, much like the kind in bodybuilding competitions on TV (which is quite similar), but he used to use glue, and his muscles were trained with those glues.

He's proud of his muscles, but he still has those gelatins. When we worked out together, I used both, and now my muscles are growing like crazy. Huh

To sum up, contemptible people think that glue and iron are fine!

I bought a pair of 30kg on **, and the postage cost of 30 yuan is a total of 128.

It will fall off the crumbs, but it will not fall much, the rubber smell will be, and it is quite heavy when I first bought it, but it is also simple to drop it in the past, put it in the ventilated place for less than a week, and then use the soaked tea water to bubble, the taste is much smaller, but it can still smell, but it is much smaller. As for the unevenness, this one must be there, but it won't be very big, only about 500 grams. The cast iron can't adjust the weight, it's inconvenient.

The biggest advantage of lagging is **. The galvanized is beautiful, and there is no taste, but it is really expensive

I have a pair, the weight is definitely the same, it feels good, there is a little crumb on the side, there is no big problem, the smell will be stained on the hands, the cast iron also has the same smell of iron, it is much better than the rust of cast iron, it is best to wear gloves when exercising.

The glue is better, it won't rust, and some of the iron is not of good quality, and it's easy to scratch your hands

Remove the dumbbell piece, observe it in your hand, press it, and pick it with your fingernails to see if you can feel the iron inside.

Some iron-clad dumbbell pieces can be seen on the inner wall of the middle hole, which is not good, because the purpose of buying rubber-clad is not to make the sound of bells, so it is better to buy iron.

In addition, the lagging is much heavier, after all, it is iron.

Easy to wear and tear I used a single iron lacquer and it felt good.

At home, it is recommended to use electroplating, and the rubberized one has a strong plastic smell!! Quite smelly!!

The lagging is better, the weight is well controlled, and the weight needs are different for different parts of the exercise.

However, the price is more expensive than electroplating.

Of course, it's good to be glued.

There is no sound when it is put down.

It won't fade yet.

The plating is going to fall.

For household use, use rubberized.

Not two or three dollars.

Plating is much more expensive than lagging one.

A pair of 20 kg of variable weight dumbbells, electroplating is 60 70 yuan more expensive than the rubber, I think the rubberization is good.

However, you should be careful not to buy raw rubber.

It smells terrible when you put it at home.

There is basically no peculiar smell of cooked gum.

Good lagging is good.

It is not easy to break things.

It costs about 30 yuan to be able to change the weight.

I occasionally bought 15kg of lagging and 30kg of plating.

More than 20kg buy electroplating and light buy lagging rubber.

Lagging is cheap and the new purchase has a pungent smell of rubber.

Plating dumbbells are a little more expensive, not a little off, and will not fade.

But since you're using it at home, it's better to use a cheaper one, and it's practical to save.

And I didn't take it out for others to see.

The lagging is generally the kind that is particularly light, used for fat reduction, and can be used in some parts such as deltoids. In general, the dumbbell is too light for muscle gain.
