(Brief) Resin shaker tutorial!

So, some of you might know about my Splatoon and Karamari resin shakers, and to request I wrote a small tutorial on how to make your own shaker mold!

The first step is to plan on how you want your shaker to be! You can draw a project on paper, make a model on your PC, whatever you feel like! When you are ready you just need to sculpt (or 3d print) your prototype! Look at existing shaker molds to understand how they're built and to take inspiration!

I used air-dry clay, which I regret because the shrinkage deformed them, so I suggest using a polymeric clay like fimo!

Sand them if needed and make sure the shaker has enough room for the size of whatever you want to put inside!

The second step is to get the silicone for the mold. I used two types of silicone in the past, each with their pro and cons:

The one on the left is a instant silicone putty, it's quick, easy to use and doesn't make a mess, but it's way less flexible and deteriorates quickly. The one on the right is standard clear silicone, which I used for my most recent molds. The quality is better and the transparency helps you seeing what you're doing, but since it starts from a liquid base you need a container and it's messier, not to mention the risk of air bubbles (you can see them actually in there lol). I suggest researching beforehand what kind of silicone it's best for your work! Remember for both types to make sure your shaker stays parallel to the ground, you can make sure of this by putting the item face up on a flat surface (or inside the container) and putting the silicone on top

Once your mold is ready and you wanna make a quick test to see if it worked and don't want to waste resin, use wax! i used a mix of candle and stamp wax on the first mold, and then sculpted, smoothed and refined the wax copies to use to make the mold on the transparent silicone! This step is not mandatory, only if you're not satisfied with your first result.

And you're done! You can now make resin shakers with your own shape! This method is not only for shaker of course, so have fun making your own charms!

Manufacturing Process

PMMA, derived from methacrylic acid (CH2=C[CH3]CO2H), is a significant member of the acrylic resin family. Its production primarily involves propylene, obtained from the lighter fractions of crude oil, and benzene, reacting to form cumene or isopropylbenzene. The resulting cumene undergoes oxidation to cumene hydroperoxide, then acid treatment to yield acetone. Subsequently, acetone undergoes a three-step process to produce methyl methacrylate (CH2=C[CH3]CO2CH3), a flammable liquid. Methyl methacrylate is polymerized, either in bulk liquid form or as fine droplets suspended in water, using free-radical initiators to form solid PMMA. This polymerization process links the molecules together, resulting in the formation of PMMA with a repeating unit structure.

The polymerization reactor receives a feed mixture consisting of a monomer, water acting as the reaction medium, suspending agents, and a monomer-soluble initiator. To adjust the density of the aqueous medium, decrease the monomer's water solubility, and increase interfacial tension, an inorganic salt is added. Polymerization occurs at around 100°C. After polymerization, the resulting slurry is neutralized with sulfuric acid before undergoing filtration or centrifugation. The material is then dried. This method ensures the controlled production of the desired polymer, achieved through the precise interaction of monomers, reaction medium, initiators, and additives within the polymerization reactor.

Applications of Poly Methyl Methacrylate (PMMA)

Scientists have developed an enzyme that can break down plastic

In 2022 alone, the consumption of polycarbonate was estimated at 4.51 million tons worldwide. Here, plastic bottles make up a large part because they are often based on polycarbonate.

A group of researchers has developed an enzyme that can break down a certain type of plastic, which can then be recycled.

A research team at the Department of Materials and Production at Aalborg University[1] in Denmark has developed an enzyme that can break down plastic of the polycarbonate[2] type, so that it can be recycled and used to produce plastic again.

And according to associate professor from the Department of Materials and Production Evamaria Petersen, it is much more climate-friendly than using the chemical process that is used today. “With chemical decomposition, you use much more energy and a very high temperature of around 300 degrees, whereas you use around 70 degrees to break down plastic by using enzymes”, she says.

The reason for the high heat during the chemical process is that the structure of the plastic must change so that it becomes less hard. And therefore the code for a biological breakdown of plastic, according to Evamaria Petersen, is that the temperature is high and that the enzymes can cope despite the heat.

Polycarbonate is found in many everyday products. For example, plastic bottles, garden tools and household goods are often based on polycarbonate. In 2022 alone, consumption was estimated at 4.51 million tonnes worldwide. But in order for enzymes to replace the chemical decomposition process in the future, it will require quite a few more hours in the laboratory.

“So far it is a prototype that we have developed, because in a technical process it is too slow to break down the plastic. But we are in the process of further developing it, so that the process will be faster,” says Evamaria Petersen.

In addition, the research team is developing models for enzymes that can also break down other forms of plastic so that it can be recycled. Polycarbonate has so far been considered non-degradable and therefore harmful to the Earth. But the new decomposition method may be the solution to a greener way to break down plastic in the future, so that it can be used for recycling.

How much does the physical doll cost?

What material is tpe

TPE is a thermoplastic material, but it has a high content of glue and can be recycled. Excellent processing performance, no vulcanization, recyclable, low cost, secondary injection molding, coating and bonding with PP, PE, PC, PS, ABS and other matrix materials, or it can be molded separately.

What material is silicone

Silica gel alias: silicic acid gel, which is a highly active adsorption material and is an amorphous substance. The main component of silica gel is silica, which is chemically stable and does not burn.

TPE and silicone have many similar characteristics, such as soft touch, rubber elasticity, environmental protection and non-toxicity. Silicone is a traditional material. TPE has only emerged in the rubber and plastics industry for nearly a decade or two. Both have their own advantages. However, in terms of processing performance, recyclability, and cost price, TPE meets the inadequacy of silicone materials. With more and more types and applications of TPE, TPE is the preferred material instead of silica gel.

[How to quickly identify TPE and silicone]

Silica gel: The burning flame is bright white, with light odor, less smoke, and the residue is white powder. Silica gel has transparent particles as well as other irregular solid-like materials. It is divided into inorganic and organic silica gel. The hardness range is 10~90A. Silicone has excellent tensile resilience. And TPR/TPE (based on SBS, SEBS substrate). The burning flame is yellow or yellow up and blue underneath. TPR and TPE of different hardness and substrates (the reason there is TPE, TPR is related to the different calling habits of users), the smoke produced is lighter or thicker, and the smell is also different, but they all have the special fragrance of styrene taste.

[Which one is better for dolls or physical dolls? Tpe or silicone? 】

Generally speaking, the silicone material is from 100 to 500 per kilogram, and the TPE is about 5 yuan to 20 yuan per kilogram, so you can feel that if your doll or physical doll is about 1.70, the weight is 35 kilograms, remove the skeleton 2. -3 kg. If it is a better silicone material, the cost of the material alone is close to more than 6000, plus the skeleton, headgear, eyeballs, dentures, matching parts, clothing, logistics costs, labor costs, and no retail sales of tens of thousands Price, there is only one possibility, the silicone material used in the product is very cheap.

TPE silicone doll or entity doll

Therefore, if you want a softer touch, it is recommended to use TPE material. With current technology, it is difficult to make new breakthroughs in silicone material. However, in the future, the material is likely to directly use biological cells, and it will not be any different from the touch of a real person.

Thermoplastic elastomer TPE material is one of the new materials that have been extremely popular in recent years. It is a thermoplastic elastomer material with high elasticity (or even better), high strength, high resilience, and high wear resistance of silicone rubber products. It is environmentally friendly and non-toxic in contact with human skin. It can also be used in medical and survival products for most of the time. Many materials can replace silicone products.

With the widespread application, many TPE merchants have joined the raw material business trend. However, due to the slow acceptance of new materials in many traditional industries, the pace of update is not ideal, and they are committed to contributing to the elastomer business and the social environmental protection cause. Purpose of contribution, A good physical doll with a size of 100 cm needs about 5,000. If it is two thousand yuan, the material should be made of silicone. The weakness of silicone is that it is easy to oil and feels hard and tastes great. The good material is medical silicon. Resin has no such weakness. , But generally speaking, the one-meter physical doll 2000 is hard to buy even if it is made of silica gel, it is best to see the best in kind. I bought Jiu Mei dolls. Mine is a customized model. If you buy it, it is best to customize it yourself. Follow up with the customer service. You must watch the video and watch the video. . . That’s right, the person upstairs is right. It costs tens of thousands to produce one. Of course, the cost will be lowered if mass production is used. However, if you are not very rich, it is better to pay for production than to buy.

There is a well-known domestic doll shop in Guangzhou called Yuanyiyuan entity doll shop that sells this product exclusively, the price is more than 10,000, and the price is 20,000, which is much cheaper. This is a bargain. If you don’t believe it, search on the Internet.

The price of silicone entity dolls is more expensive, domestic all-silicone dolls are more than 20,000 yuan, and those imported from Japan are generally around 50,000 yuan.

Silicone doll is a kind of artificial adult sex product, it can be regarded as a high-end masturbation device, instead of real people to satisfy orgasm. It is also a companion doll, its shape is made according to the ratio of 1:1 for girls. The face is better, and some high-end ones can also be customized. The silicone doll is soft and elastic after inflating, and the skin is similar to that of a real girl. The silicone doll is easy to carry and clean, and can be used repeatedly. All silicone dolls are made of silicone except for the bones, that is, solid dolls. All silicone dolls are more realistic in shape and soft, but the price is more expensive.
