Dice Molds

Dice Molds Background

Dice are items used for generating random numbers during a sort of social and gambling games. Known since antiquity, dice are called the oldest gaming instruments. They’re typically cube-shaped and marked with one to 6 dots on each face. The foremost common method of dice manufacture involves injection molding of plastic followed by painting.

It is through the dice molding that you are able to give your dice a desired shape and design. It is also through this process that large volumes of dice are able to be produced within a very short period.

History of Dice 

Dice have been used for gaming purposes for over centuries. Evidence found in Egyptian tombs has proven this mold used them as early as 2000 B.C.

Other data shows that primitive civilizations throughout America also used dice. These dice, during those old days, were composed of ankle bones from various animals. Marked on four faces, they were to used as magical objects that would predict the longer term. The traditional Greeks and Romans used dice made from bone and ivory.

The dice of most of those early cultures were made in numerous shapes and sizes. The modern-day cubical dice originated in China and are dated back as early as 600 B.C. They were presumably introduced to Europe during the fourteenth century.

Dice were usually handcrafted and produced on a little proportion until the 20 century. As plastic molding technology emerged, methods for applying it to dice molding were drastically developed. This allowed manufacturers to supply mass quantities of dice during a cost-effective manner.

Over the years, a spread of patents for improved methods of dice manufacture is granted.

Materials for Dice Molds

Dice Molds

Numerous materials are forged into dice throughout history. They include such things as bones, glass, wood, seeds, and metals. Today, the foremost widely used base material for dice manufacture is plastic. Plastics are high relative molecular mass polymers that are produced through a spread of chemical behaviour.

For a plastic to be suitable for dice mold, it must have good impact strength, be easily colored, and temperature stability. It’s also desirable that it’s clear, colorless, and transparent. Most dice are made with a thermoset plastic.

One, the plastic that meets all of those requirements is acrylic (PMMA). Cellulose-based plastics also are used.

Since the polymer, which makes up the majority of the plastic is usually colorless, colorants are added to form the dice more appealing. These could also be soluble dyes or comminuted pigments. To supply a white color, an inorganic material like titanium oxide could also be used.

Other inorganic materials like iron oxides are often wont to produce yellow, red, black, brown, and tan dice. Organic dyes like pyrazolone reds, quinacridone violet, and flavanthrone yellow can also be utilized.

A host of other filler agents are added to the plastics to supply a durable, top quality set of dice. To extend the workability and adaptability of the polymer, a plasticizer is included.

Plasticizers are nonvolatile solvents and include things like paraffinic oils or glycerol. To enhance the general properties of the plastic, reinforcement materials like fiberglass are added.

Other protective agents that are added include ultraviolet (UV) protectors like benzophenones to stop UV degradation and antioxidants like aliphatic thiols to alleviate environmental oxidation. Finally, compounds also are used during manufacture to assist in mold dice.

This agents generally includes materials like ethoxylated fatty acids, metal stearates and silicones, which help with the removal of the plastic from the mold.

Designing Dice Molds

The standard die may be a six-sided, plastic cube. All sides are usually marked with one to 6 spots or dots. These dots are arranged, such opposite sides always total seven. For instance, the one-dot side is opposite the six dot side, and therefore, the three-dot side is opposite the four-dot side. During a two dice game, the dice are shaken and thrown on a surface.

The rolled amount is indicated by the edges of the dice that are confronted. If the dice are well-balanced and fair, all sides have an equal chance of landing confront . Counting on the sport, the player will either move her piece or collect money supported this rolled volume.

Some popular games that use dice include craps, chuck-a-luck, and poker dice. Board games like backgammon,and Parcheesi,Monopoly also use mold dice.

Dice Molds are available in a wide variety of sizes and colors. On the other hand, 12 mm dice are typically used for most board games. These dice are considered imperfect because they need rounded corners, which reduce randomness.

Since these dice are often utilized in children’s games, they need to be designed to satisfy certain toy safety standards. Casinos use perfect dice which will be handcrafted. They’re generally larger than parlor game dice with a side measuring 33 mm.

These are red, translucent dice that have extra-sharp edges and corners and white dots. With this design and construction, rolls with these dice have the best probability of being fair.

Specialty dice are produced for several different applications. In some cases, the spots on a typical cube die are replaced by words, pictures, or symbols.

Divining dice, which are wont to predict future events, have different predictive messages on each face. Poker dice have card faces printed on all sides. For blind people, Braille dice are available.

Some games require dice that have a special number of sides and may provide a greater number of outcomes than standard dice. These poly dice can have anywhere from three to twenty sides. They’re used extensively in fantasy role-playing games.

Dice Molding Process

The key design element of dice manufacture is that the mold. Mold may be a cavity carved in steel that has the form of the merchandise that it forms. Typically, a mold is formed from two pieces that are forced together to make the cavity.

When plastic is injected into this mold, it takes on the mold’s shape because it hardens.

Since dice are solid cubes, employing a standard mold isn’t practical because they might take too long to chill. For the production of dice, a special mold design is employed.

This mold is formed from separate chambers, which create individual elements of the die. Since the individual pieces cool, they will be forced together to make a single unified object.

The mold is then opened, and therefore, the die is ejected. Special release agents are used to making the plastic easier to get rid of from the mold. This mold design saves time because the smaller pieces can cool sooner.

The mold is then opened. When the mold is opened, the individual pieces are forced together to make one solid cube. Because the mold was appropriately designed, this cube has indentations that will become the dots on all sides.

The cube is then ejected from the mold, coated, and passed to the subsequent phase of production via conveyor. Meanwhile, the two-piece mold closes again, making it able to create the subsequent die.

Dice molding companies may introduce additional steps, but still, the procedure for molding the dice will remain the same.

Painting and Polishing Dice Molds

to finish the assembly of the die, they’ll be washed and dried before the ultimate decorations are applied. First, the spots are appropriately painted. For specialty dice, words could also be printed, or images could also be applied to every side.

Company logos or other advertising can also be applied. These are often stickers or coatings. The coatings used during this step are specially formulated to stick to the plastic and dry quickly.

Depending on the ultimate use of the dice, they’ll be bulk packaged to be used in board games, or individually wrapped for consumer sale. For board games, the dice are packed up into boxes and shipped to game manufacturers a bit like the other component material.

Once they are sold on to consumers, dice are typically put into plastic blister packs with a cardboard backing. This package has the twin purpose of protecting the dice during shipping and advertising the products.

The finished dice molds are then packaged in cases and shipped by truck to distributors.

Quality Control of Dice Molds

The goal of any dice molds manufacturer is to ensure that molds meet the ultimate market standards. The surest way of ensuring this is by putting I place appropriate dice mold quality control measures.

To ensure that every die produced meets specified quality standards, a variety of internal control measures are taken. Before manufacturing, certain physical and chemical properties of the incoming dice molds raw materials are checked.

This includes things like relative molecular mass determinations, chemical composition studies, and visual inspection of the looks.

More rigorous testing can also be done. For instance, stress-strain testing is often performed to work out the strength of the plastic. Impact tests help determine the toughness of the dice molds.

During the dice molding process, line inspectors are stationed at various points on the assembly line. Here, they visually check the plastic parts to form sure they’re shaped, sized, and colored correctly.

They also check the integrity of the ultimate packaging. If any defective dice are found, they’re secluded from the assembly line and put aside for reforming. Computers also are wont to control plastic use, mold retention time, and line speed.
