A hot runner controller is a temperature controller used to control the temperature in the hot runner. This helps create the most consistent part(s). Hot runners usually make the mold more expensive to manufacture and run, but generate savings by reducing non-productive plastic and allowing shorter cycle time.
Conformal cooling is a technology utilized in the plastic injection molding industry to improve the efficiency and quality of molded parts. Traditional cooling channels in molds are typically straight and uniform, leading to uneven cooling and thus, longer cycle times and potential defects in the finished product.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
Increasing the temperature of the material or mold allows the material to flow without stiffening before the cycle completes. [1] If the temperature is increased too high, there is a chance to cause a different type of injection molding defect referred to as a burn mark. [3]
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is required.
The blow molding process. Blow molding (or moulding) is a manufacturing process for forming hollow plastic parts. It is also used for forming glass bottles or other hollow shapes. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding.
Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.
In non-steam molding, water will heat the tool to a constant temperature. Plastic will be injected to the warm tool. In steam molding, steam is injected at 160 degrees to heat the tool. When the tool reaches a predetermined temperature (about 140 degrees), the plastic is injected. Cold water is immediately added to the process to cool the ...
