Technical terms related to plastics (S line)
- Injection molding
- Vacuum forming
- biodegradable plastic
- Rotary Processing
Like crystalline plastics, the material itself has a very low coefficient of friction.
The higher the degree of crystalline nature, the higher the accidental lubricity, and it is often used for components such as gears and bearings.
Metal parts require maintenance, such as the use of lubricants, but replacing them with self-lubricating plastics reduces the amount of maintenance required.
Injection molding is a molding method in which plastic material is heated, melted, pressed and injected into a mold and then cooled and hardened.
Compared to other molding methods, this method is superior to mass-production of the same product and generally uses thermoplastic resin, but thermosetting resin is sometimes used.
In this method, plastic sheets are heated to make them soft and then covered with a mold, and then placed in a vacuum so that they adhere to the mold and are cooled before being formed.
This is a particularly widespread method of thermoforming plastics, and is called "drape forming" when a male mold is used and "straight forming" when a female mold is used.
This is a bonding method in which the same monomer as the acrylic material is poured between the adherend and the adherend and allowed to polymerize at a certain temperature.
This is the bonding method often used for acrylic tanks in aquariums, and is superior to solvent bonding (method of melting the surface of the adherend) in terms of strength, durability and beauty in appearance.
When acrylic materials are used, it is possible to increase the thickness and area by using multiple sheets of acrylic, but the removal of air bubbles during adhesion is a major factor in the quality of the finished product.
It is a plastic that contains oxygen in its main chain and is broken down by microorganisms.
It has the advantage of being environmentally friendly because it does not remain in nature as waste, and it requires less heat to be depreciated.
On the other hand, they are more costly than ordinary plastics and have disadvantages such as limited functionality and durability, and they cannot be reused and must be disposed of.
In some cases, they can be manufactured from biological resources (bioplastics), but in others, they can be manufactured from petroleum.
This is a machining method in which the workpiece is fixed to a shaft and rotated, and the cutter is moved to cut the workpiece in an axis-symmetrical manner.
It is mainly used to process products into spheres and cones, and can be adapted to various processes by changing the conditions of blade application and other factors.
