Does the belt speed even matter ?

[Endeffect]

If i got a assembler 2 that produce iron plates and have a fast gripper how can then a fast belt help me if there are not enough products ?

sorry im just a beginner of the game cuz i need a little bit more of these plates and asked me if upgrading my belts help me.

ty for answer !

Belt speed at the start of the game is rather irrelevant. It becomes relevant as you try to scale up. When you have not just one assembler needing materials, but 20 or 30, A single yellow belt packed to the brim won't be able to feed them all- but a red one might be able to.

This game is a lot about recognizing where the bottleneck in your factory is. In your example, You have an assembler 2 producing something, but it's not making enough of it- So the bottleneck is the input belt, it's not bringing enough materials to the machine. A fast gripper and a fast belt won't help if there isn't enough material to go on the belt to begin with, so trace it back further, and you need more plates, and if you need more plates you need more ore. Tracing it back forward, you need more ore, more furnaces to convert that ore into plates, and then to funnel those plates to the machine that needs them down the belt, using up more of it's capacity.

Get used to thinking like that- Think entire production chain, Not just that specific step. To make gears you need Iron plates, to make iron plates you need iron ore.

As you get accustomed to the game you can shorthand it to some extent, but being able to think around the entire production chain will help you recognize bottlenecks in the future.

In the beginning, you start with 30 electric miners (15 on each side) for 1 yellow belt of f.e. iron ore. You put those in 48 stone furnaces (24 for each side) and you get a full yellow belt of iron plates, which you can use up all. f.e. produce gears with enough assemblers to fill half a yellow belt (2 plates -> 1 gear)
If you let it backup, the furnaces fill up to 100 each.

Later you can upgrade this to red belts. Use 60 miners (30 for each side of the belt), put it in 48 steel furnaces, which are exactly 2 times as fast (24 for each side) and get a full red belt of iron plates.

the red belt is able to move twice the amount of iron

(btw: the 60 miners can also be reduced by researching mining productivity, to get more iron per miner)

Aside from belt speed, underground belts can reach further the higher tier they are, which is very useful when you find yourself having to run a belt across a spot with less room.

Also if you haven't set up defences yet though, don't worry about red belts for now. Making red belts costs a lot of iron for the early game, and you will be making a lot of pollution from all the iron that gets mined and smelted for red belts.

Faster belts have higher throughput, i.e. they transport more items per second. When you start producing more items than a slower belt can carry, you can upgrade to a higher speed belt to carry all the items.

And it's also, well, faster, which means that the item will reach its destination faster. This becomes useful for example with items that are on a spoilage timer, because you should be trying to process them as fast as possible to keep them as fresh as possible.

[Nonotorious]

Not massively, unless you find a machine is struggling for ingredients it can be either the belt is not delivering enough items or the inserter is too slow but it's generally pretty obvious if the belt is empty.
In space age even less so because you can get belt stacking, doubling to quadrupling belt throughput.

Assembler can smelt iron ores into plates?

Did you mean another product? Or an electric furnace instead of an assembler?

I'm just trying to understand what you are trying to do to help you better.

The usual answer is to add more rows of belts, more assemblers, or more electric furnaces to produce more of what you need.

Engineers usually upgrade their belts to faster and more expensive belts when they can afford the higher material costs and need the higher throughput in a smaller area for a larger factory.

The answer is hidden in the question.
Longer factory lines. More assemblers. And more product to move in and out.

imagine you got 20 assembler dropping iron plates to the same lane of belt.
