injection molding machine

Injection moulding is a method of manufacturing parts by injecting materials into moulds. The first method of processing plastics is injection moulding. In this process, the plastic is placed in the hopper, which then injects the plastic heat through a long chamber and a reciprocating screw. Later, it is softened into a fluid condition. The nozzle is located at the end of the chamber. The liquid plastic is forced to cool through the nozzle to close the die. When the plastic is cooled and cured, the semi-finished product withdraws from the press.

Extruder

Plastic kneading is a method of mass production, during which plastic raw materials are melted to form a continuous summary. Extrusion processes are generally used to manufacture films, connecting sheets, tubes, profiles, bars, coat wires, filaments, wires, and cables. Together with the injection moulding machine, the dull plastic is placed in the hopper and fed into a long heating chamber. At the end of the chamber, the material is pressed out of a small opening, or in the shape of the desired product. After the plastic is separated from the mould, it is placed on the conveyor belt to cool. Blowers are sometimes used in this process to assist in cooling.

Blow molding machine

Blow moulding is a forming method for manufacturing hollow plastic products. It relies on gas pressure to make the rubber-like billet which is closed in the die cavity blown into the secondary moulding technology of hollow products.

Thermoforming machine

A special plastic processing method for processing thermoplastic sheets into various products. The sheet is clamped on the frame and heated to the softening condition. Under the external force effect, the sheet is made close to the die surface to obtain the shape similar to that of the die surface. After cooling and setting, the finished product is ready to be repaired. This process is also used in rubber processing. In recent years, new developments have been made in thermoforming, such as the continuous production technology from extrusion sheet to thermoforming.

Compact forming

Compression forming is a common method in thermosetting materials, which is generally not used in thermoplastics. In this process, the material is kneaded into the desired shape. Plastic moulding powder and other materials are added to the mixture to produce special mass. When the die is closed and heated, the material passes through hardening to form its desired shape. Temperature, pressure and the length of time used in the process depend on the desired results.

Calender

Also known as calendering. The final process of heavy leather cleaning. The plasticity of fibers under mixed heat conditions is used to flatten or roll out parallel fine skews on the surface of fabrics in order to improve the pickup process of fabric gloss. The material is fed in, heated and melted, then formed into sheets or membranes, then cooled and rolled up. The common calendering material is polyvinyl chloride.

Kneading machine

Kneading, blank in three-dimensional non-uniform compressive stress effect, from the die hole or gap extrusion to reduce cross-sectional area and increase the length, become the required product processing method called kneading, blank processing called kneading.

Vacuum forming machine

Vacuum Forming, commonly known as plastic absorption, is a plastic processing technology. The primary principle is to use vacuum to absorb the flat plastic hard sheet on the surface of the die after heating and softening, and to form after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other work.

Rotational molding

Rotary moulding is also known as rotational moulding, rotational moulding, rotational casting, rotational moulding and so on. Rotary moulding process is to take plastic raw materials into the mould first, then the mould rotates along two vertical axes and heats them continuously, so that the plastic raw materials in the mould are evenly coated and melted on the whole surface of the mould cavity under the effect of gravity and heat energy, forming the desired shape, then cooling and setting, demoulding, and finally obtaining the product.
