Comparison the injection molding machine from RobotDigg 

Hi, you are doing a great job man, great channel you have, very informative. actually i am a student and my project is fabrication of table top injection molding machine. Can you please tell me what kind of stepper motors (model number) did you use in this project and also any recommendation of cheaper stepper motor models that can be used for clamping and extrusion. it would be a great help.

12:08 that machine is living it's best life 🙈

Thank you so much for your video. I have a problem in setting sensor to coltrol temperature of screw (how much sensor, type of sensor, how to coltrol...) Beside, when the sensor contact with screw => sensor does not work, and when place a insulated fiml between them (sensor and screw) => sensor works. So i am happy to hear some comment from you. Or any document that can help me to solve it. Thank you again and hope you the best!

How do you select the motor for screw?

Bom dia meu amigo. Ótimo trabalho esse seu vídeo. Se aceita minha opinião em relação ao canal de injeção do molde, deixar o ângulo do bico de injeção do molde pouco mais aberto em relação ao bico de injeção da máquina, fazendo com que om plástico não retorne formando um "chapéu", entre nos dois bicos. E como um amigo disse nos comentários, poderá colocar um bico quente no molde para não esfriar o plástico.

Я конечно не инженер ни разу, но тут прям видно, что есть нюансы: 1)канал литника должен быть коническим, чтобы деталь с литником легко извлекалась 2)деталь должна оставаться на подвижной части прессформы, для этого будет достаточно трех отрицательных приточек, которые будут запирать пластик в ней, а система удаления будет в дальнейшем выталкивать всю деталь из формы 3)поставьте температурный датчик на неподвижную часть прессформы, ее температура должна быть не ниже 60-70⁰, это компенсирует растекаемость пластика и увеличит время застывания в канале (деталь лучше прольется и легче будет извлекаться). 4)возможно стоит сделать горячий канал, или уменьшить его длину, чтобы минимизировать остывание в нем пластика. Эта машина должна иметь цикл 20-30секунд в автоматическом режиме, без помощи оператора.

how much it cost that machine?

I think you should consider removing this video and replacing it when you get the machine working finally.

So after every shot you have to clean the nozzle. Manually take out the part

What motor you used to runn compression screw

very nice and simple machine and system :)

Wow, that was painful to watch, I only made it to 6 minutes.

Please tell me the price of mini machine

So, you have to stand by the machine with a pair of scissors and hope every 5th part comes out okay? That builds confidence.

Excelente!!

What kind of screw you explore in machine?

Any Dealer in India.

The mold expulsion is upsidedown...

How much

Rs

Hello it is machine xmp 17

this is a single phase machine

Not

Very nice. We complement each other. We produce special injection molding machines for thick-walled and transparent large parts. We can cooperate.❤

It's hard to work, so how much does it cost ???

Hi,good machine, but,u need some major changes and modification my friend u need to learn principle of injection molding first good luck ✌️🙏
