Making Injection Mold

There are many reasons as to why the process of injection molding is very popular in the field of plastic production—the most common reason is that it is the best means of producing enormous and identical quantities of plastic parts. Let's know more about the Types of Injection Molding Machines now. Injection molding machines are classified mainly by the type of driving system they use: Hydraulic Injection Molding Machine, Electric Injection Molding Machine, and Hybrid Injection Molding Machine.

Pros:

* The base price of these machines are significantly less than its alternatives.

* Replacement parts are lower cost and easier to find

* Less money in overall maintenance

* Hydraulic parts are more resistant to wear and tear-they are built to last.

* Molding system is slightly easier to control for higher level products

* Hydraulic molding machines have exceptional clamping force

* Large number of units available on the used market

Cons:

* Hydraulic fluid is constantly pumped 24/7 which is a greater amount of power consumption than alternatives

* Fluids can leak out and damage parts around (bad for clean rooms)

* Higher temperatures needed for molding which takes more power and time for cooling

Pros:

* Fast cycle times:These machines are digitally controlled, meaning the process is entirely repeatable and needing no supervision.

* Cleanest process

* Low noise levels for production

* Less energy consumption:Electric injection molding machines only use energy when in action—meaning the motor output is only equal to that of the load requirements.

* Accuracy and Precision is its strength for advanced products.

* Greater repeat-ability creating less scraps and waste products

Cons:

* Up front price is expensive

* Availability for replacement machine or parts can be challenging on used market

* Maintenance supervisors must be savvy with Hydraulic and Electric presses

* Majority are toggle clamp and very limited with two platen clamp

Pros:

* Diversity of designs for products

* Best of both: Hybrid molding machines combine the energy savings and accuracy of electric molders with the force-generating capacity of a hydraulic unit.

* Replaced motor: Hybrids have replaced fixed-speed DC pump motors with variable-speed AC drives so the pump only operates when required and uses the necessary amount of oil for process efficiency.

* Less downtime: These require less maintenance and experience less downtime than an all-hydraulic or all-electric molding machines.

* Price point: Falls nicely between all-hydraulic and all-electric molding machines, making it an affordable option. Especially for medical device manufacturers.

Cons:

* All hybrids are different which causes problems with matching right press to product

* Most difficult to find same replacement machine per application in United States

* Maintenance supervisors must be savvy with Hydraulic and Electric presses
