PLASTIC INJECTION MOLDING MACHINES: TYPES AND BENEFITS
PLASTIC INJECTION MOLDING MACHINES: TYPES AND BENEFITS
Why is the process of injection molding very popular in the field of plastic production?
There are many reasons behind it .The most common reason is that it is the best means of producing identical quantities of plastic parts and is very large in size. Machines are classified mainly by the type of Opening and Closing of direction of the mold clamping unit :
The process of operating machines in both Horizontal and Vertical Injection Molding are the same .They follow the same steps . Injection molding falls into an injection mold, holds the mold together to allow the part to harden, open the mold and then eject the parts.
Horizontal Injection Molding:
Most Commonly used machine of plastic molding is the Horizontal injection machine since injection molding began.It is ideal for cylindrical parts and used for higher-volume production runs. KSB Lion is the leading manufacturer of Horizontal Injection Molding Machines.
Some advantages of horizontal injection molding machine are:
It can produce larger parts and more complex shapes
It can use multiple cavities and multi-color molds
It has higher production efficiency and lower operating costs
It has better alignment and stability of the mold
Vertical Injection Molding:
Vertical injection molding is suitable for small inserting products.It is easy to place as it require small space.In Vertical injection molding the product needs to be removed by hand after ejection, which is not easy and not considered as automatic operation. So we can say that a vertical injection molding machine is only suitable for producing small plastic parts.
Some advantages of vertical injection molding machine are:
It can perform insert molding or overmolding easily
It has better access and visibility of the mold
It can use gravity to assist in filling and ejection
It has lower clamping force requirements and less wear on the mold
Both horizontal injection molding machines and vertical injection molding machines have their own advantages and disadvantages depending on the type, size, shape, material, complexity, quality, quantity and application of plastic parts. Therefore, choosing between them requires careful consideration of various factors such as cost-effectiveness, productivity, flexibility, accessibility, safety and maintenance.
