Molding

Anyone know about molding? How do I create the mold, i hear about this oozmoo or something but I cannot find such a thing in the UK. What kind of alternative can i use? how about vaseline around it, would that work? I would experiment but I don't have very much molding stuff.

Mold Making?

So, after making this awesome isntructable (it's curing now!), I got ideas for other concrete projects. My favorite so far is making a concrete lamp. I want to make a mold of a lamp (light bulb in it) and then cast it in concrete. I'd then put a real lampshade on it and call it art. My problem is...I have no mold making experience. Do you guys have any tips, know where to get silicone, etc?Thanks!

Making a mold.

I am trying to make a fascia panel for a car. In order to do that I need to make a cast of one of the voids in a panel, from a vehicle console, since it can't be measured easily. I want to make the cast so that I can then make an accurate template from which I can make the panel I need. I am looking for a material that is non-destructive to the plastic panel that contains the void. That will create a rigid solid replica of the void. I know nothing about making molds and casts. Thanks in advance.

Mold for Polyurethane Resin?

Hello, I purchased a Polyurethane Resin mix (Part A/Part B) to create a guitar. I’m wondering though what material I can use to create the Mold? I normally work with Wood, so this is all new and exciting, but oh so confusing. Can I create a mold out of wood and coat it with a silicone spray? Do I need to use some other non-porous material? Any insight would be excellent. Thanks, Rich

White mold on algae?

Recently (as in for a few weeks), my bowl of algae has developed white goop floating in it. It looks like flour, and sticks together like flour. I (intelligently, I believe) have not tasted it, but it or something else in the algae smells terrible (well, worse than how terrible algae already smells, lol). I'm worried because Im donating samples of this algae to my middle school to use for experimentation, but a few, um, white things got in the samples. I really want to know what this stuff is. If anyone wants pictures, I'll upload some,. but basically it looks like flour and floats on top of the algae.

Molding is Not My Forte

I am currently working on a future Instructable that involves a lot of molding. Hence, I've discovered that my molding abilities are not up to par. It has been almost twenty-four hours since I poured the clear casting resin and it is still tacky on the top. Is this normal, or did something go horribly, horribly wrong?

Leaking plaster mold? Answered

Hi All, I have a six-part plaster mold that leaks. It is so time consuming to make another one and I would like to fix it. During construction I  slightly over shaved some lines that during casting it leaks. I can use it but it creates more work. Now I want to make a master mold from that but want to fix it first. Does anyone know how to fix such problems on molds? I really appreciate the help. Thanks and hope to hear Belgin

Vacuum Forming Molds

hey guys ive been reading a lot lately about vacuum forming and homemade vacuum forming machines (kudos to everyone who has made one by the way, theyre awesome), because i want to start early on my halloween costume this year and after some research i found vacuum forming would be the best way to make my costume. so my question for you guys: what do i make the molds out of? unfortunately, everywhere ive looked, there hasnt been a real detailed description of how to make the molds for the parts, its usually more along the lines of "now put your molds on the platen and place the heated plastic. . ." without describing how aforementioned molds came into existence. thanks a ton in advance!

Wood molding casting

Need some ideas:I have an antique wooden chest of drawers. Most of the wooden molding around the top and bottom is long gone, BUT I do have two original sample pieces. They are a pretty intricate design and there is no way I'll find anything like them today. So I thought I'd make a mold and cast some to replace the missing wooden strips. I smeared up the thin wood strips with Vaseline and pressed them into plaster of parís. Well the mold turned out fine, but now I am struggling with what to use for a casting material. I tried plaster of parís, it was to fragile. I tried painters caulk, but it was too flexible and looked like heck. Thought about mixing sawdust and glue, but am pretty sure the texture will be wrong and grainy. It needs to be stain-able so I can make it look like it's wood and semi rigid so I can get it out of the mold. Any suggestions??

Can you use a Plaster mold as a Blow mold?

I wanted to make a hollow plastic shape & not able to afford a metal blow mold. Can I use a plaster mold with wood reinforcement as a substitute for the metal one?The Idea is to heat up a plastic bottle that can fit in the mold cavity & slowly blow it up with an air compressor.You think this might work, or do you think I may need more reinforcement in the plaster?

best material for molding polystyrene

I'm melting Styrofoam w/ acetone and wanting to put the goop in a gear mold; however I'm not sure what material I should be using for the mold.  I was originally going to do it in ABS plastic, but wasn't sure if the polystyrene would glue itself to the mold as the acetone evaporates.  So I was thinking of aluminum or possibly stainless steel.  Your thoughts?

Print a cast for pewter molding

I have a 3D model that I would like to have printed so I can use it as a cast for a pewter mold. It is a simple pin that I designed in 3DSMax.. Would the cast have to be metal, or is there some plastic/poly that would take the heat of molten pewter?  I don't want to have to pay a jeweler to do this, I already have the model in 3D, it seems like it should be easy to print a cast so I can make them myself..

Plastic Resin Casting and Molding advice

Hi I'm making my first plastic resin cast and the mold for it using the tutorial here: http://www.b9robotresource.com/plastic_casting1.htm One difference to that tutorial however is that the object I am making a mold of is something I've make in air-dry modelling clay. I've spent quite a bit of time making the original so bit worried about pouring the silicone for the mold onto the clay object - will it break the clay down or is there some way to prepare the clay (varnish or something?). I've put a test of dried clay in water and it has broken down in five minutes. Can anyone who has done this sort of thing before advise please? Thanks in advance. Garrett

Molding Aluminum: With Gravity Die Casting

It's expensive, untested and dangerous.The idea goes like this. Start with a coffee can foundry, possibly powered with Biodiesel or Propane. Then design a mold for what you want to build using Autocad or some variant thereof. After it's finished, send the design to a machine shop to have it built out of steel. When you receive the permanent mold, melt the aluminum and pour into the mold repeatedly and often.The idea seems like a good one to me, I'll be testing it soon enough using common screw clamps to keep the mold tightly secure.Has anyone here done this? The closest I've come to doing it myself is pouring into a muffin tin.The photo below is a picture of the results which was taken from another board found here, you'll need a login, the photos are located in the forum under Machining and Tooling.Give me a shout if you dig the idea.UPDATE 5/24/07It works! Using my Harbor Freight Mini-Mill I cut out pockets in two pieces of 1018 steel, each about an inch deep, and four inches across. I then cut inlets in both pieces and welded some scrap steel U channel on the tops of both mold sections to form a pool enclosure for the excess aluminum to collect inside of and stay safely contained.Then I lit the candle on my foundry and melted the aluminum while at the same time pre-heating the molds, (connected using C-clamps) in the oven. When the aluminum melted, I poured it and it instantly solidified. After about 2 minutes of running around in a panic I cracked the mold open. The detail level is incredible. Impressions made in the mold with a fly-cutter can be seen in the casting. The casting is bright, shiny, and seemingly devoid of any burs usually associated with unfinished aluminum castings.I'll provide photos later of the test mold and casting.

Creating hollow, clear mold. What materials?

I'm trying to create a Metroid from the titular video game series but I'm not sure of which direction I should go. As you can see, the top (i''ll call it the "head") is semi clear but contains a nucleus within it. So far the only method I can think of is with clear resin. Issues though are that I dont know how to leave an empty space for the body to fit within the head and I dont have a pressure pot available. I've never created a mold before and my only experience is clay sculptures. What methods could I use to create this? All I have to work with is my garage and some clay at the moment and although I'm willing to go out and spend some money, I wont be buying something like a $300 pressure pot.
