I'm working with the local civil protection director to make a prototype of a torpedo style rescue floatation device to be donated and mounted on natural wood posts at our most historically dangerous beaches. These torpedoes are abusively priced ($150 USD), not available locally here in México and not available in all-natural materials but I'm working to change that. We need a local bioplastics supplier with materials well suited for this purpose with sheet plastic that can be manually heat-formed over a mold. And for a much larger scale impact, we need an estimate of the cost of mold that could be used with recycled plastics, bioplastics and biodegradable plastics also to blow mold them for us. If we can raise the funds to pay for the mold ourselves, the devices can be relatively very inexpensive which will make them very accessible and help save lives everywhere they're used.
this is amazing how do you control or achieve varying thickness on a bottle? lets say the neck has its own thickness and the body has its own thickness too?
There is usually a die (stationary) and a die tip/mandrel that is connected to a hydraulic programmer cylinder that moves the die tip or mandrel up or down thereby changing the "die gap" which determines the thickness of the parison (i.e. the sleeve of plastic being extruded).
So like don’t quote me because every place is different, but there’s usually a machine you throw the plastic into and it’s put into a hopper that solidifies it after it becomes crushed up and it recycles into the next batch.
The cap isn't put back through because it's usually made from a different material (type of plastic) and very often a different colour to the bottle so you would end up with colour contamination in the finished bottles
i want to work in Australia in blow moulding plant have any vacany please inform me. i m work in india in bolw moulding plant as production engineer last 5 years.
@@whogavehimafork no I haven’t but the fundamentals are the same with die settling on and machine. the real art is making a bottle. And we are a job in job our company 20 machines and up to 10 or more die sets a week between 3 people 24 hours a day 6 days a week.
That depends on the machine manufacturer. We have three machines, 2 german and 1 American. All three use pressurized leak testing, then reject based on pressure loss during testing.
Since it is closed loop, will there be an accumulation of material that has many heat histories from being melted and formed over and over? Should there be a purge stream to prevent this accumulation? I.e., a fraction of the cut pieces will be disposed of rather than reintroduced to the beginning of the process. I am a chemical engineer by schooling and new to the plastics industry. I am thinking in terms of chemical stream splitter where we have a purge fraction and recycle fraction.
I think you'd have to test at various points...Looks like these ALL receive testing for leaks. I'm sure the process has been evaluated to minimize waste and there is perhaps a cutoff for in-process recycling... BUT with every bottle being tested the process is probably sound as is...for a lifesaving device there might be heightened concern.
From my experience as a blow molding operator, plastics plant maintenance man, and mechanical engineer, I can tell you that the material being recycled (what we call "regrind") is typical used too soon for there to be a noticeable decline in the quality of the plastics. We generally use no more than 80% regrind and no less than 30% (except on startup with a new color for which we have no regrind). But enough of it gets used that we don't have the same issue with degradation that recycling plants have. Unfortunately not all of it gets used. Occasionally it gets contaminated with dirt from the outdoors, or hydraulic oil from leaks within the machines. In which case the contamination makes it unrealistic to try and clean it all to be reused so it must be discarded to a landfill I'm afraid.
Listen to your teacher. Coming from an engineering graduate and worker in plastics. Plastics are both the bane of our existence and the answer to our ancestors prayers.
It is. My plant produces both injection and blow molded products, all made from HDPE. There are many different formulations of HDPE, however. Some "disagree" with blow molding but do quite well with injection. In my plant, the formulation of how molding resin we use can be used in injection molding, but our injection molding resin cannot be used in blow molding. Both are HDPE. Quite fascinating and complex

for people who are in tb the answers are here thank me when you are in skl lo/l Clamping - the clamp unit consists of metal plates (or platen). The process begins with the mould being clamped together under pressure to accommodate the injection and cooling processes. Injection - the molten thermoplastic material, which has been melted by pellet form in the barrel of the machine, is injected under pressure into the mould through either a screw or ramming device. Dwelling - once the molten plastic is injected into the mould, more pressure is exerted to make sure all the mould’s cavities are filled, using hydraulic or mechanical pressure. Cooling - the plastic is left to cool and solidify within the mould. Opening - the movable platen is separated from the fixed platen to separate the mould. Ejection - ejection is completed by the use of rods, a plate or an air blast to remove the plastic component completely from the mould.;]

It really is. The process is quite fascinating to watch in person
POV: you are writing a comment to say how awesome this is in case your DT teacher checks the comments
FOR SOME REASON...
this is amazing how do you control or achieve varying thickness on a bottle? lets say the neck has its own thickness and the body has its own thickness too?
There is a servo controller, changing the thickness by pulling the core of the die head.
There is usually a die (stationary) and a die tip/mandrel that is connected to a hydraulic programmer cylinder that moves the die tip or mandrel up or down thereby changing the "die gap" which determines the thickness of the parison (i.e. the sleeve of plastic being extruded).
;_; I've watched this 2 trillion times
NO YOU HAVE NOT YOU LIAR 🎉
very excellent
As someone who has modelled 3D CAD models of bottles, this is so satisfying to watch.
So now no one can tell me that bottle caps can't be recycled. They could go back to the original loop to be melted.
To be precise they didn´t manufacture any bottle caps in this video.
So like don’t quote me because every place is different, but there’s usually a machine you throw the plastic into and it’s put into a hopper that solidifies it after it becomes crushed up and it recycles into the next batch.
depends on what plastic the bottle caps are made from
The cap isn't put back through because it's usually made from a different material (type of plastic) and very often a different colour to the bottle so you would end up with colour contamination in the finished bottles
Look up thermoplastics and thermosetting plastics
I'm here because I got curious about how one would make plastic lightbulb casings.

What happens to the initial plastic mold, is it reused? if so where and how is it removed from the bottle?
I believe it will be a 2 part mold that just releases it automatically.
Watching this for a Res Mats Lesson. I'm extremely confused.
The blow-molded bottles are tested with vacuum, not pressurized air...
That depends on the machine manufacturer. We have three machines, 2 german and 1 American. All three use pressurized leak testing, then reject based on pressure loss during testing.
Since it is closed loop, will there be an accumulation of material that has many heat histories from being melted and formed over and over?

You might be more interested if you see these machines in person. The process is fascinating
Is this extrusion blow moulding or injection moulding?
(Extrusion) blow moulding, as the title says. Injection moulding is a different process, which has a couple of things in common
The title is calling it blow moulding...
Injection molds "shoot" the molten plastic directly into the mold threw gates in the Cavity (top part of the mold)
