Exploring the Versatility of Plaster Bandages

Posted by EnvironMolds , Labels: , , , , Sunday, July 2, 2023 11:02 PM

Plaster bandages may seem simple and even queer at times. However, they open the doors to a world of possibilities in life casting itself. Use them to form shell molds or even make body molds directly.

Plaster bandages may look like simple pieces of fabric infused with plaster. But they play an important role in the life casting process, mostly related to capturing the form of the human body in a body mold. Indeed, they work for body molds in much the same way as orthopedic casts and prosthetics.

The bandages are easy to use. Simply roll them out and soak them in water before squeezing out the excess liquid. This makes them malleable and easy to work with. All that is needed is applying the strips and allowing them harden as the moisture evaporates. This will form a rigid mold that captures the shape of the body.

Plaster bandages have dual applications in life casting. The most common usage is to form a shell mold over the alginate mold – as the latter is flexible, it needs to be reinforced to be able to retain its shape during the casting process.

On the other hand, some life casting artists apply the bandages directly on the body. This is especially useful for capturing the shape of the abdomen for making a life cast of pregnant belly. Keep in mind that the plaster mold will not capture intricate details and contours, therefore, it cannot be used on other parts of the body. Moreover, care is required as the plaster tends to release heat which can be uncomfortable or even cause burns on sensitive skin.

However, some artists use them even on the face to replicate the shape for making masks. Dimensional stability is a given here.


How to use?


The process is also easy and straightforward. Just roll out the bandages (cut to size if required) and wet in a bowl of water before squeezing and applying on the alginate mold or directly on the body. A couple of layers will be required to ensure that the mold is thick and sustainable.

While applying the bandages, ensure that they overlap each other and are thicker on the edges. Working in a crisscross manner is the best approach.

Once the plaster has set and dried properly, demolding is as easy as twitching the body a bit before inserting the fingers from the edges of the mold to remove it from the body.

What makes plaster bandages an attractive option is that they are easily available and cost-effective too. They can be used by beginners, hobbyists and professionals alike. They are non-toxic and lightweight; they will not cause allergic reactions on the skin either.

In sum, plaster gauze forms an essential part of life casting. And an easy option for sourcing them is EnvironMolds. The art manufacturer and supplier is renowned in the world of mold making, casting and life casting for providing top quality materials, supplies, tools and equipment at the best prices.

Must-Haves for a Mold Making Art Studio

Posted by EnvironMolds , Labels: , , , Thursday, June 1, 2023 2:03 AM

Arts like casting and life casting begin with making a mold. The mold forms the basic underpinning that will dictate the character and quality of the final casting. Given the wide variety of materials and techniques that can be used for mold making, both amateur and experienced mold makers need to not just familiarize themselves with the options, but also stock the studio with the requisite products.

How to make a mold

 

In addition to this, making molds will also entail the use of tools, supplies and equipment that must be kept handy so that the mold making process can continue without any interruptions or wastage.

Let us take a look at some of the essentials for a mold maker:

  • Materials –Molds can be made with plaster, alginate, latex rubber, silicone rubber, polyurethane resin, etc. The choice will depend on varied factors like the master that is to be replicated, technique to be used for making the mold, material used for casting, etc. Whichever material is being used, it should be stocked in sufficient quantity to eliminate the possibility of running short and having to stop the process. In fact, it is better to have extra material on hand as the mold does not always turn out perfect on the first attempt!

  • Tools –Mold making involves the use of very many supplies and tools, most of which mold makers tend to take for granted. But can one afford to be stuck just because a spatula or gloves are not available when one reaches out for them? Always stock and replace regular items like mixing bowls and containers, mold boxes or containment materials, release agents, spatulas, mixers, cutting and trimming tools and measuring apparatus, apart from gloves, aprons, safety goggles, etc.
  • Equipment –When working with rubbers and resins, a mold maker cannot overlook the possibility of air getting trapped in the material and forming bubbles in the mold. This will call for a vibrating table, pressure pot or vacuum pump and chamber, depending on the materials being used.

Additionally, the work area in the studio should be set up properly. The workspace must be bright and well-ventilated with adequate space to move around freely. At times, a humidifier may also be needed. There should be sufficient storage space as some materials need to be stored in appropriate conditions to maintain their effectiveness and longevity. Even the supplies and equipment should be kept in drawers or shelves rather than just being left around on the table or floor.

As a final note, always opt for top quality mold making materials and tools from established brands and reputed suppliers. Some of them will even provide guidance on how to make molds, tips on what is needed and even share tricks for successful mold making!

The Usage of FiberGel Alginate

Posted by EnvironMolds , Labels: , , , , , Monday, May 15, 2023 7:05 AM

Alginate is a handy material commonly used in life casting. A fiber infused formula has been specially prepared to increase the strength and tear resistance of regular alginate that can be used in animation works.

Alginate is considered the be-all and end-all product for life casting. Even though skin-safe silicone rubber is now available, alginates are more popular and commonly used when it comes to making body molds. This dental grade material is safe for the skin even as it captures the surface impressions with a high accuracy of detail.

While alginate comes in different types, a special formulation has been created specifically for high-end detailed E F/X work. Known as FiberGel E F/X grade alginate, it has been independently tested 40% stronger than other leading brands.

The other benefits apart from extra strength and tear resistance, extend to preventing runs and drips making it perfect for applying on vertical surfaces. Moreover, the fiber matrix will retain moisture, thus reducing the shrink rate and allowing for delayed casting time sans any loss of detail. The mold will also stay soft and flexible for a longer time.



Delving into the Basics


The application of fiber alginate is the same as regular formulations. The manufacturer’s instructions related to the mixing proportions and timing have to be followed to the letter. The mixture should be smooth and free of lumps. It has a set time of 5 to 6 minutes when the consistency and thickness is right.

The alginate should be applied with a gentle but firm hand. Press it down slightly to ensure that it reaches every contour and crevice of the body part. This will ensure that the surface details are captured properly in the body mold.

The model has to be prepared properly prior to the application. The skin surface should be clean, dry and free of any creams or other products. A thin layer of release agent – like petroleum jelly – is preferable as it will avoid snagging of the alginate in the fine body hair.

Safety precautions are necessary in the form of ventilation, gloves and even communication signals with the model. It also essential to ensure comfort and support for the model for the time it takes to prepare the body mold. Props can be used as a reinforcement to maintain the desired posture of the model.

Once it has set properly, the alginate body mold can be easily demolded with a little twitching and prodding. It comes off easily and is ready for immediate use, after the requisite cleaning and finishing. In fact, time is in short supply here, even though the FiberGel alginate does push the evaporation window a bit, allowing more time for making the casting. Different materials like plaster, silicone and resin can be cast in alginate molds.

Finally, getting a life cast right comes down to practice along with oodles of patience. The artist has to keep trying and perfecting the art till they master the intricacies of life casting!

The Many Faces of Liquid Latex Rubber

Posted by EnvironMolds , Labels: , , , , , Sunday, April 23, 2023 6:07 AM

Liquid latex rubber is in a class of its own with a broad range of artistic applications that are not just limited to mold making and casting. It occupies a special place in the world of masks and special effects.

Liquid latex rubber is like the Holy Grail of artistic applications. This fluid material is easy to use and can be used for different purposes. It proves to be flexible, tear resistant and displays exceptional tensile strength across its varied range of applications. It is not only durable but also economical as compared to other mold making and casting materials.

Let us take a look at some of the uses of latex rubber:

  • Molds – Liquid latex can be easily used to make molds of different objects. It will capture details well and can even be applied on vertical surfaces – like architectural details – without it running off. Anything from plaster to urethane or polyester resin can be cast in the latex molds to make figurines, moldings and the like.
  • Casts – What sets casting latex rubbers apart from their mold making counterparts is that they are less viscous. The casts turn out to be like a thin skin, making it perfect for making props, gloves, hollow toys and the like.
  • Mask making – Liquid latex rubber is most identified with making masks. It is the first choice for making different types of masks that replicate the contours of the face to the last detail. It can be finished with monster, zombie or other spooky effects.
  • Costumes – The same rubber is also used to make customized costumes for Halloween and other occasions.
  • Special Effects – Name any kind of special effects on the body and liquid latex can be used to create the same for film, television and theatre productions. Realistic looking wounds, gashes, scars and other effects become possible in the hands of an experienced artist. Many people use it for body painting and even nail art.
  • Protective Coating – Latex rubber is used to form a protective coating on tools and other surfaces. Simply dipping the object in the liquid latex a couple of times (while allowing each successive coat to dry in between) will render a better grip and comfort in usage apart from providing electric insulation.
  • Waterproofing – Dipping a material in liquid latex will make it waterproof after curing. This is usually used for making raincoats and rubber boots that will not allow water to seep through them.
  • Repair Jobs – Pouring a bit of liquid latex serves well for covering up holes and tears in certain fabrics.
 
When it comes to making a choice of liquid latex rubber, RD-407 Mask Making and Casting Latex is useful for all the above purposes. It remains the prime choice for making a latex mask.

In sum, there’s not much that cannot be done with liquid latex. The humble material is easy to use – as simple as pouring it into the mold or dipping the model into the rubber!

Troubleshooting Common Issues with Two-Part Molds

Posted by EnvironMolds , Labels: , , , Tuesday, April 11, 2023 3:21 AM

When a mold is made in parts from the original object, the going gets complex and can involve some troubles for the mold maker. Following is an attempt to clarify the common problems with solutions.

Mold making is a complex art of creating a negative image of an object. This mold is then used to cast a three-dimensional replica of the original object and results in a carbon copy of the same!

There are different techniques of making molds; even the materials used to make the molds can vary – from simple clay and wax to resins and rubbers. In addition to this, the mold cannot be made in one go at all times. Depending on the shape, undercuts and other detailing of the object, it may require the mold to be made in two or more parts.

Needless to say, multi-part molds are more complicated and time-consuming. The method is not only longer, but can get quite intricate too. Given the elaborate process, mold makers often face different issues in the making of multi-part molds.
 


Let us take a look at the common issues and how to deal with them:

Air Bubbles – When air bubbles form in the mold, they will lead to voids in the final casting. These are more common in two-part molds. Therefore, the mold maker should be careful when mixing the mold making materials and pouring the mix into the mold. Some of them – like resins and rubbers – will require degassing in a pressure pot and vacuum chamber respectively.

Flashing – This refers to the excess material seeping out of the mold and forming a layer around the part. This can be due to problems with the parting line and the mold makers are always advised to design it properly. Errors in the parting line can also cause issues during the demolding process. Do not apply excessive force in the clamping either, as this can also make the mold making material seep outside.

Warping – One of the common reasons for two-part molds to get distorted is lack of proper alignment. It is crucial to align the parts of the mold properly before beginning the casting process. Only when the parts fit together properly, will it lead to a perfect casting.

Voids – It is not just air bubbles that can cause voids in the casting. This can also be due to the simple fact that the material was insufficient to fill the entire mold. Therefore, it is important to ensure that the mold is completely filled and the material seeps into all the undercuts and niches of the mold.

Apart from these, there are other mold defects like chipping, cracks, finger tracks, flow marks and so on. These can usually be corrected in two part molds by way of sanding and smoothening the surface. Other issues like depressions or gouges may require using additional material to fill them before sanding the cured mold.

In sum, as the object is complex, the mold making and casting will require extra attention and caution for sure!

Encapsulation by Way of Clear Casting Resins

Posted by EnvironMolds , Labels: , , , Friday, March 31, 2023 3:55 AM

Embedding a special object or even a biological specimen in a clear casting resin is an easy way to preserve it for eternity! The clear quality of the resin ensures that the object stays visible on all counts.

There are casting resins and then there is clear casting resin! Indeed, while polyurethanes are being used for making different types of resin castings, there’s something special about clear resins!

What sets clear casting resins apart from the rest of their ilk is that they can be used for encapsulation. Indeed, the clear quality of the resin makes it perfect for embedding different kinds of objects. They will stay clearly visible from all angles and look beautiful while at it.

The objects to be encapsulated can range from leaves, flowers, buttons, shells and other small objects to even special keepsakes like a stamp, coin, ring or a photograph. The casting process is used to make different objects like paperweights, key rings and jewelry that look both attractive and unique due to the items encapsulated inside them. The same technique also serves well for making point-of-purchase displays, rapid prototypes, special effects, sculpture reproductions, giftware, etc.

On a more serious note, science also falls on encapsulation for preserving biological specimens, like insects, plants and even small animals.
 



How to do it?


Clear casting resin is available as a two-part polyurethane casting system. It is usually mixed one-to-one by volume. Special molds are available that are specifically designed for clear casting. However, most artists prefer to make their own molds to ensure uniqueness in every feature of their casting.

While the mold can be made of almost any material, silicone molds are considered best. Especially, molds made with platinum-cure or condensation-cure silicone material will help preserve the clarity of the casting.

The casting process involves pouring the mixed clear casting material into the mold before gently embedding the object in the desired manner. Prior to this, it is important to degas the clear resin as it is prone to trap air bubbles. A pressure pot will work well here and the casting can be left to cure in the pressure pot itself.

Color can be added to the resin during the casting process – in the form of pigments or dyes. This can create a wonderful marbling effect in the casting.

All clear casting resins cure at room temperature. The cured cast will be UV resistant and non-yellowing.

Points to note


Encapsulation is not as straightforward as simply placing the specimen in the resin casting. The object has to first be cleaned thoroughly. It should also be completely dry. Leaves and flowers will have to be dried to remove the moisture content, and preferably coated with a preserving chemical. Biological specimens call for careful handling.

When it comes to the choice of clear casting resin, the number one option is obviously AquaClear Clear Casting Resin. Available at EnvironMolds, this is optically clear and cures to a hard and non-yellowing resin.
