Being one of the top most hot runner mould manufacturers in India, Dowell Moulds is recognized for offering hot runner injection moulds India. The hot runner moulds suppliers that we produce are very accurate, making it easy for them to deliver high performance in several industries. Leveraging on our reputation as a precision hot runner mould manufacturer in India and supplier, we offer hot runner moulds per clients’ specifications developed to withstand the test of time and offer the best quality of every mould.
A Hot Runner Mould is the specific type of injection moulding tool that has a heated runner system through which the plastic material is kept in the molten stage as it passes through the injection unit to the mould cavities. This system stands out from a conventional cold runner mould in which the material gets frozen in the runners and usually gets thrown away.
We also provide Hot Runner Cap Mould solutions, designed for efficient and precise cap manufacturing, ensuring minimal waste and faster production times.
Heated Runner System: Hot runner system is made of heaters that ensure the plastic material which is used in molding stays in a molten state. Some of these components are a manifold and a number of heated nozzles that inject the molten plastic into the mould cavity.
Material Efficiency: Compared to cold runner moulds, hot runner moulds do not require cold runners hence using less material hence the production cost is low. The content that is forced into the mould is incorporated in the final product, in its entirety.
Improved Cycle Times: Some of the benefits of hot runner systems include; Since the plastic is held in a molten state, cycle time is reduced hence increasing the production rate.
Consistent Quality: Conventional moulds lack control on injection process, the cavity interest tends to be filled in uneven way while hot runner moulds minimize this problem. Thus, it leads to manufacture of better parts and components with minimum or no defects like sink marks, weld lines, and short shots.
Enhanced Surface Finish: It is often seen that the products made from hot runner moulds have better surface finish since the plastic material has no tendency to cool off at any point before reaching the mould cavities.
Complex Part Design: Hot runner systems make it possible to have more complicated part design since the material storing systems maintain the flow and curtails initial solidification.
Injection: Material in the plastics in a molten state is pumped from the injection unit to the hot runner system.
Distribution: The heated manifold and nozzles are responsible for injecting the molten plastic into the mould cavities in equal manner.
Filling: The material, which is the plastic, flows into the mould cavity to form the required part thus creating the desired shape.
Cooling and Solidification: The parts are then permitted to cool and to crystallize or solidify in the mould.
Ejection: Thus the mould opens and with it the finished parts are thrown out with another set placed in its place in the continuous making of the parts.
Hot runner moulds are in use with many sectors such as automotive, consumer products, electronics, packaging, and medical equipment sectors for manufacturing precise and excellent quality plastic components.
Due to its features, hot runner system results in a lot of prospective material save, increase in manufacture speed, and final product quality, making its use to be widespread amongst the injection moulding processes.
