Takeaways
- š” The video introduces the topic of Injection Molding Machine and how it works.
- š ļø Injection molding is a step-by-step cyclic process that is versatile in creating plastic products.
- š The injection molding cycle includes mold closing, injection (filling the mold), cooling, mold opening, and ejection of the product.
- š The process is classified under cyclic rather than continuous processes.
- š”ļø In the injection molding process, thermoplastics are heated, melted, and injected into a relatively cold mold to form the desired product.
- š§° The primary resources required for injection molding are machines, materials, molds, and manpower.
- āļø The first hydraulic injection molding machine was designed in the USA by scientist John W.
- š Products made using injection molding include electrical parts, household items, agricultural tools, and medical devices.
- š Injection molding is used to produce many automotive parts such as door handles, bumpers, dashboards, and taillights.

Q & A
What is the primary topic discussed in the video?
-The primary topic discussed is the introduction to the injection molding machine and its construction, along with an overview of the injection molding process.
What type of process is injection molding classified as?
-Injection molding is classified as a 'cyclical process,' where each cycle involves multiple steps such as mold closing, material injection, cooling, and product ejection.
What are the basic components required for the injection molding process?
-The four essential components required for injection molding are the machine, material (usually thermoplastics), mold, and manpower (operator).
Who designed the first hydraulic injection molding machine, and when?
-John W. developed the first hydraulic injection molding machine in the USA.
What happens during the injection molding cycle?
-In the injection molding cycle, the mold first closes, the material is injected into the mold (indicated by the orange color in the diagram), cooling occurs (indicated by the blue color), and finally, the mold opens and the product is ejected.
What type of materials are typically used in injection molding?
-Thermoplastics are commonly used in injection molding, where they are melted and injected into a relatively cold mold to form the final product.
What kind of products can be made using an injection molding machine?
-Various products can be made, including household items, electrical components, automotive parts (such as door handles and bumpers), agricultural tools, and medical equipment.
How is the injection molding process different from continuous processes?
-Injection molding is a cyclical process, unlike continuous processes, meaning it goes through distinct stages for each product, starting with mold closure and ending with product ejection.
Why is the cycle time important in injection molding?
-The cycle time is crucial because it determines how quickly products can be manufactured. Each cycle must be completed efficiently for high productivity, and the details of cycle time will be discussed in a future video.
What are some examples of automotive parts made using injection molding?
-Examples of automotive parts made using injection molding include door handles, bumpers, backlights, and dashboard components.
