Rubber Tubing

What Is a Rubber Tubing?

A rubber tubing is a tubular product made of materials such as natural rubber or synthetic rubber.

Rubber tubing primarily functions through its elasticity. It can transmit various forces by stretching, compressing, or bending. Additionally, it can also transport fluids internally. Rubber tubing finds applications in various fields including medical, laboratory experiments, industrial processes, automotive, sports, and household uses.

Typically, a standard rubber tube consists of layers for internal fluid or gas flow, an intermediate layer for strength and elasticity, and an outer layer for protection and resistance to friction. The characteristics of rubber tubing include elasticity, flexibility, water resistance, heat resistance, chemical resistance, and insulation properties. Due to its diverse properties, rubber tubing is suitable for a wide range of applications.

Rubber Extrusion

What Is Rubber Extrusion?

Rubber extrusion is a processing method used to manufacture various rubber products by melting rubber material at high temperatures and extruding it from a mold.

The operating principle of rubber extrusion consists of three main stages: mixing and heating, extrusion, and cooling and shaping. Firstly, rubber material and additives are mixed and heated to melt at high temperatures using an extrusion machine. Next, the melted rubber is extruded into a mold by the screw of the extrusion machine, and finally, the rubber extruded from the mold is cooled and solidified, shaping its form.

Rubber extrusion is utilized in a wide range of products, including hoses, sealing materials, tires, and long-length products, as well as components with complex shapes. Its characteristics include high productivity and the ability to manufacture products with intricate shapes. Moreover, it is widely employed across various industries due to its relatively low manufacturing cost.

Rotational Molding

What Is Rotational Molding?

Rotational molding is a molding process for manufacturing hollow plastic products.

In rotational molding, thermoplastic resin powder is placed into a mold and rotated in an oven. The powder melts and adheres to the inside of the mold, which is then cooled, and the product is removed. This molding method is used in the production of various products such as tanks, drums, buckets, cases, furniture, playground equipment, traffic signs, and outdoor lighting.

Rotational molding offers many advantages compared to other molding methods. Firstly, it allows for the production of products with complex shapes. It also enables the manufacture of large-sized products and is relatively cost-effective. Another characteristic feature is that it allows the use of materials that cannot be used in other molding methods such as injection molding or blow molding.

Roll Forming

What Is Roll Forming?

Roll forming is a manufacturing process for producing long products by continuously compressing and bending metal sheets with multiple rollers.

The operating principle involves multiple rollers shaped differently, and a metal sheet fed forward by a feeding device. The sheet undergoes gradual compression and bending at each roller, resulting in the continuous production of products.

Roll forming finds applications in various fields such as construction materials, automotive parts, household appliances, and industrial machinery. It comprises rollers, a feeding device, a frame, a power source, and control devices. Its characteristics include high productivity, shape accuracy, material efficiency, low cost, and design flexibility. When using roll forming, factors such as material selection, sheet thickness, accuracy, cost, and safety need to be considered.

Pressure Vessel

What Is a Pressure Vessel?

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.

Operating on principles of sealing, pressure resistance, corrosion resistance, and thermal resistance, pressure vessels must be sealed effectively to prevent leakage and withstand the pressure and characteristics of the stored substances. They are utilized across various industries, including chemical, food, pharmaceutical, energy, construction, and even in household applications.

Structurally, a pressure vessel comprises a body, cover, valve, and fittings, marked by its high strength and durability. Safety assurance involves selecting the appropriate vessel and adhering to manufacturing, usage, and storage regulations. Key considerations when choosing a pressure vessel include pressure resistance, corrosion resistance, thermal resistance, safety precautions, and compliance with regulations.

Powder Metal Part

What Is a Powder Metal Part?

A powder metal part is a metal component manufactured by compressing metal powder and then subjecting it to a heating process called sintering.

The manufacturing process consists of four stages: powder production, mixing and forming, sintering, and finishing. Metal powder is produced using methods like hydrogen reduction or atomization, mixed with lubricants and additives, and then compressed into molds. Subsequently, the sintering process bonds the metal powder particles together, completing the part.

Powder metal parts find applications in various industries including automotive, household appliances, machine tools, medical devices, and electronics. They are particularly suitable for parts requiring complex shapes and high precision, offering high strength and durability. Their characteristics include the ability to produce parts with complex shapes, high precision, high strength, and minimal material waste.

Polyurethane Molding

What Is Polyurethane Molding?

Polyurethane molding is a process of producing polyurethane resin by reacting polyol and isocyanate.

There are primarily two methods of molding: high-pressure foam molding and injection molding. In high-pressure foam molding, polyol and isocyanate are mixed and injected into molds under high pressure to foam. On the other hand, in injection molding, the mixed raw materials are injected into molds using an injection machine and then solidified. In both methods, polyurethane resin is formed through a chemical reaction.

Polyurethane molding has applications in various fields such as automotive parts, household appliances, furniture, construction materials, medical devices, and sports equipment. Its features include high flexibility in shape, lightweight nature, thermal insulation, impact resistance, and chemical resistance.
