wow

[tuuexx]

that spray-on shell process sure looks to waste alot of matrial-sure brush-on is,nt a cheaper way-or polyester resin...or plaster?

[BJBEnterprises]

@tuuexx The person applying the spray shell had the settings set too high with regard to material flow. If the gun and spray head is set correctly, there should not be dripping of material. To answer the questions about other backing material, you can apply fiberglass/polyester (or epoxy) or plaster if you prefer. The spray material is best utilized on larger surface areas for quick mold shells because you can demold within hours as oppose to a day or more.

@BJBEnterprises -thanks-that makes sense.i have used your products before,and have ALWAYS had great results ! -keep up the great work

[bettarox2]

I have a HUGE question . Okay so I am just starting out . Like LITERALLY just started out. I'm still just a kid , but i dream of one day becoming like Glenn hetrick . I know I wont be doing molds and stuff for awhile . But I was wondering if there are any tips or trips to make it easier ://

[CGkawaiicrafter]

Would the flexible foam ITSELF stick to plain silicone without mold release????

[BJBEnterprises]

@CGkawaiicrafter The short answer is No; the foam would still release from the silicone mold but it is still advised to use a light application of mold release so the skin formed on the foam is not stressed as the part is de-molded. Often times we see that if soft foam is cast into a silicone mold without release, more force is required to de-mold the part and the skin might tear or pull away from the part. We recommend our E302 "Rocket Release" for use with foams.

WHAT IS THIS BLUE MOLD STUFF WERE DO i get it?

[BJBEnterprises]

@game33able It is TC-5024 with SC-5001 Thickening agent. This system is a two-part silicone molding material that is normally a flowing, castable product. Adding the SC-5001 makes it brushable and will hang in thicker sections. You can contact us to order product from the website address in the video.

[Appaloosakisses]

How do you determine the range of flexibility of urethane foam. What is the determination between softer and firmer?

[BJBEnterprises]

@Appaloosakisses We have a couple classifications of flexible foam that we formulate. Cushion style foams are typically soft and lack a rubbery skin. The lower their density, the softer they feel. We also have "Self Skinning" foams which do build more of a skin with enough back-pressure in the mold. For the same density as a cushion style foam, they are firmer and less compressible. Stay tuned for a new video on foams from BJB.

[jackdanielmason1969]

Excellent video, it's one of the things i've been looking for, don't think the wrong thing, but i've been wanting to make flexible body parts.

I would recommend talking us through it all instead of the music, other than that, thankyou so much for posting the info.

Now i just have to find the products in Australia, australias not very creative sometimes :)

[BJBEnterprises]

Thank you for your comment. We will enhance our videos to do as you mention in the near future. As far as Australia not being creative, we find that there are many talented BJB customers in your part of the world and some of the biggest movie productions in the world are coming from your neighbor New Zealand.

***** Super cool videos *****

[BJBEnterprises]

Yes, some people will use a mold like this for fiberglass parts but keep in mind that epoxies and polyesters will be harder on the silicone materials so you may experience shorter mold life. An additional mold release sprayed in may help extend the life of the mold.

[moraisdesantana]

If I make a silicone mold, I can make a fiberglass helmet with this mold?

[Dach101]

@moraisdesantana yes , silicone is good for fibreglass casts, use a wax release first

[filmmaker91361]

How would you make a two-piece mold of the entire head?

[BJBEnterprises]

@filmmaker91361

Leaving the Master part in the mold, you would put some appropriate mold release onto the first mold flange (Vaseline works well) and then repeat the process in the video. When done you will have a two piece mold. Silicone will bond to itself but does not bond to most other hard, clean surfaces.

[cthenut]

Is there a book of casting and making molds you recommend?

[cthenut]

Is there a book you recommend for making molds and casting?

[oslocrimecity2]

Hey.

Since i am not a person living your neck of the woods but in norway, what would it cost and/or what do I need to order from your website to make a mold?

Regards and thanks for an very good informative video.

[BJBEnterprises]

@oslocrimecity2 You can order directly from us over the phone or via email. If you contact us we can send pricing of the materials you are interested and the Data is on our website. We ship international orders every day and always welcome interest from outside the USA. Best regards!

[iruss71]

Is it possible to use fiberglass in a silicone mold?

I was just wondering what its max temp rang was, if any?

[BJBEnterprises]

@iruss71 Yes, you can laminate fiberglass and resin systems (epoxy, polyester, etc) into silicone molds. In general, Silicone mold material has very high temperature resistance and can withstand post cure temperatures required in some laminating systems. You may want to use an appropriate mold release (spray waxes, Par-films, etc) with the silicone to ensure mold longevity. Some users do not use a mold release but mold life may suffer. Mandrels are also popular with silicone material.

[JasperPalmer]

Where does one learn these things?

[BJBEnterprises]

Many technical schools for design and also art schools will have classes on mold making. Many people learn these skills on the job. Otherwise, You tube is a great resource for how-to videos. To learn which materials can be compatible with one another, it is best to call our technical staff to discuss a project.

[CraptasticLMAO]

Is the silicone stuff that will harden or something dangerous for your body and skin etc?

[BJBEnterprises]

There are 2 different types of castable silicone: Tin and Platinum based. It is not recommended that you use a Tin based against the skin. You'll find that most medical grade or skin safe silicones are Platinum based.

[JohnnyC989]

How much would that cost to make? I wonder if you could make a mold for a goalie mask that you could make real masks from ?

[mertmuratkocaman]

what material did u use? im asking about flexible foam ? what is this?

[BJBEnterprises]

The foam is a two-part liquid resin (urethane) that will expand after being mixed. The product number is TC-265 A/B and it cures to a 2.5-3.5 lb density. It cures to become a soft, flexible foam and bonds to the skin previously brushed into the mold. There are different foams available that vary in hardness and weight. These foams can also be pigmented to make colored foam parts right out of the mold.

[Defas13]

what material is used for making glove mold ?

[BJBEnterprises]

The Blue silicone is TC-5024 A/B with SC-5001 Thickening Agent. The rigid urethane shell that is sprayed onto the back of the silicone is SP-200 A/B. See our website to download Data Sheets.

[BJBEnterprises]

Yes, Sculpey can be used as a master pattern. You would want to be sure that the silicone you use is a "Tin-Based" system and not a "Platinum" based catalyst. Sculpey may contain some elements of sulfur that will cause curing issues with a Platinum silicone. The Blue silicone you see here is our TC-5024 Tin-Based with TC-5001 thickening agent to make it brushable.

[IsrealFloresto]

@BJBEnterprises can you make a cast from a wax model

[BJBEnterprises]

Yes, a wax model would work fine. The silicone will not have any problem curing against and releasing from wax.

[julzabro]

can a Sculpey piece be the master?

[starshock01]

if hardened yes
