what is Cold and hot running for plastic parts?
Cold running is a process for producing plastic parts in which plastic material is injected into a mold at room temperature. which is great for creating precise and intricate shapes Hot running is a process for producing plastic parts in which a heated plastic material is injected into a mold, it is better for applications requiring higher strength and stiffness.
What are the advantages and disadvantages of Cold and hot running for plastic parts?
Cold running is a process that is used to form plastic parts at room temperature. It is a cost-effective way of producing parts that have complex geometries and shapes. Cold running is often used to produce parts that are thin-walled, highly detailed, and require tight tolerances. The process is also suitable for producing parts that require a smooth surface finish. The main advantage of cold running is that it is a fast and economical process. Another benefit is that it is a clean process and does not require the use of any cutting fluids.
Hot running is a process that is used to form plastic parts at high temperatures. This process is used for parts that require greater strength and superior dimensional accuracy. Hot running is also used for parts that require a glossy finish or have intricate details. The main advantage of hot running is that it produces parts that have high strength, superior dimensional accuracy, and a glossy finish. The main disadvantage of hot running is that it is a more expensive process than cold running and requires more setup time.
