Hi friends i have just now made an extruder with the help of the blueprints and thank you Dave for sharing the details clearly.
I have just now completed with what are the material i have got with my place and i checked the running of the machine and it’s good. I have an idea of making beams and with that i can do some small things. i will update after i finish my first step . Thank you all and have a good day.

Hello friends,
Good day . I have just now started creating some products and  i hope the number of products with different shapes will come soon .

I feel its strong enough for making children furniture and similar things.

i’m still trying to make some new things for common usage like lader, pallet –  used in the industries, stools , shelves etc…. These are my ideas.

If anyone suggest some different ideas please share and it’s most welcome.

Looking forward to hear from you all guys.

Good day.

hey Rajan. what is your screw size; diameter and length. And, can it extrude a 4″ by 4″ beam? I’m in the process of building one, and main main products are going to be fencing posts.

Hi Jwase,
Good day. Thank you for your reply with some question.
My screw ID is 27mm and the Length is 530 mm ( total screw area ).
I have not tried for 4” circular or rounded beam but square and rectangular beam i have made.

Thank you and have a nice day.

Hi, could you take several photos. I am interested in how you joint nozzle with pipe. Do you use welding or just nuts&screws?
Also do you heat up pipe during extrusion process (some guys use such technics).

Tnx in advance!

Hi,

Ranjan. Great Product. That means we can make, table and chair set also.
I am sorry not so familiar with terms, What is ‘PP’? Please clarify?
Also, I can see the shredder you have made, how do we give shape to the product?

Thank you

Hello Friends,
Thank you for your feedback and comments and yes i used nails , nuts and screws to join and make the product. Yes i am using the heat process only during extrusion.

Thanks once again and have a nice day.

@rajan

With what materials do you have successful experiments (I mean good quallity beams)?

Could you share temperature regimes you used for HDPE, PP, PS (may be you tried  PLA, etc)?
What type of plastic is easier to remove from tube after extrussion?
Do you use any piece of wood inside the tube during extrussion process to make preasure inside tube – to make you product more smooth?

Also I am interesting about you screew (do you used screew with compression)?
And what speed of screew do you set during extrusion process?

Tnx.

Hello Friends,
Good day. Sorry for not coming online for long time due to my work commitment and busy with my work. Now i have come with a new product using the PP beam .

I just want to explain for all the questions so far asked is that i am fully using PP waste only. The temperature control i am fixing at the Extruder is 220 degree C at the barrel and 230 degree C at the nozzle .

I have just took some square tube of 3mm wall thickness and making the beam .

As for as the joining is concern right now i am using nails only to fix each together. But i need to try with some screws which gives stronger bonding of each joining. But the thing is i don’t want to spend more on it by using different screws , bolt and nuts. So i am just using some nails with some drilling and joining the beams.

With that details i just want to show you all my next new product made out of PP waste . Here we go…….

Hi there, it is good to read that you are making such nice things from the pp beams. Mabey you can help me out here. We are also busy with making pp beams for an art project. We mounted a 6x6cm pipe to the extruder nozzel and start filling it with pp. We give counter presure with a wooden beam in the pipe that is pushes out when the pipe is Filling. So fare so good. But now it goes wrong when we cool down the pipe (also slow cooling) the beam iplodes a bit and there is a hole in exactly in the middle of the beam over the whole lenght.

Do you have any tips to avoid the hole and implotion of the beam?

Hello Bondjack,
Nice to meet you here and thank you for your comments. Before explaining for your question i just want to know what is the size of your screw L/D and what is the RPM you are running. Please check the speed and the pressure of output and also the size of the mold ( the size of the pipe , you said you have fixed 6×6 cm pipe ) . Meanwhile i just want to say i didn’t use any wooden pipe or anything else together.

I am using only the square pipe and just fixed it in to the nozzle. After filling with the melted material i just put it in the water for few minutes to shrink and to get cooled. After that i can remove the beam easily without any struggle and there will be no whole in the middle for the entire length of the beam .

Hope this will help you to come out of the problem you are facing.

Have a nice day.

Hi Rajan, What’s your motor HP? What gear-ratio are you using?

Hi Rajan,

I don’t know the shrew size. The extruder is bought secondhand and we didn’t had a spec sheet with it. So we changed the heating to 180/190 and this makes a big difference, we where 40deg higher before. After that we put the wooden beam under pressure and let it cool down.It is quite a nice result. i attached a picture of the machine. I will have a look at the extrusion speed.
