There are four molding methods, such as [1] stick pipe method, [2] centrifugation molding method, [3]rubber cast molding method and [4] direct pressure methodHere is the features of the material

Polyamide resin made from oil has attracted attention as a new material of buttons since about 1960.
The mold injection method making use of thermal reversibility is adopted for the processing.
Because mass production is possible, it is suitable for general buttons. The buttons which are combined with metal parts and others are more popular than the ones made from nylon resin single material now. Here is the features of the material

It is the urea resin material which is produced with the facility and the technology brought in from Italy.
Because it cannot be dyed later, we color it at the stage of raw material. We pile up the material boards while matching colors and patterns, and then transform them to small round sticks by putting pressure and heat on them with the extrusion machine, push them out and cut them into round slices at the exit. Then, after regulating its water amunt, we put them in the dies of compacting machines, compress and heat them, and then they get transformed into the shape of buttons. After that we dry and polish them after removing the burr (unnecessary thing which protruded from the gaps of dies).Here is the features of the material

Takase Shell：It has the shape of conch and is produced most for buttons. Its whitish light rainbow color is the characteristic. As for shape, reratively flat ones are produced a lot but it is possible to produce ones with the carving of patterns and letters, and sole shape as well. Butterfly Shell：It is a bivalve called margaritaceous shell, which are categorized into three types like white butterfly shell, black butterfly shell and brown butterfly shell by its color tone. Mexican Abalone：The green color called peacock is the feature.Here is the features of the material

They are produced by processing the fruit which ripens and falls on the ground naturally from "Tagua palm tree", which makes its habitat in the tropical forest of Ecuador. They are eco-friendly buttons returning to soil at the time of disposal.
Because the fruit shows its beautiful ivory flesh of fruit when its skin is peeled off, it is called "an ivory nut".
It has the soft touch only special to natural material in both points of material texture and luster. It is a superior material being easy to treat like easy to dye and process as well. Here is the features of the material

The history of buffalo horn buttons dates back to the ancient times,and it is recognized as a button material following nuts and shells in the old days. The materials of buffalo horns has been imported from Foreign countries.　Here is the features of the material

The material hides of cows, horses, goats, etc. are imported by North and South America, and Australia.
After the necessary processing is given to the hides it is cut small and knit a button . The form is fixed with press working. They are painted with paint, and made buttons called basket style.Here is the features of the material

For the raw materials of the wood buttons, the broadleaf trees such as Tsuge (box tree), cherry tree, ebony, birch, olive are used, and they are imported from Southeast Asia (Thailand, Philippines, Malaysia).Here is the features of the material

Casein resin is made from the rennet casein, whose raw material is milk..
To make the material, we first put white pigment, pearl foil (this is put in to get the colored pattern like a pearl when it becomes the product), water and others into the raw material and mix them, then leave it to age for twenty-four hours, put it in a pushing out machine and knead it thoroughly with heat and pressure, and push it out. We can make materials with patterns and shapes of round stick, or belt by changing the shape of the part at the exit.Here is the features of the material

Ii is possible to make ones with delicate designs and volumes that are unable to be expressed with metal press work..
In addition, if there is one archetype, it is possible to make rubber molds and produce in large volume with them.Here is the features of the material

Brass is an alloy of copper and zinc called yellow copper too.
Because it has the property that it can spread, it is possible for both press working and cutting work..Here is the features of the material
